A window handle that turns without properly securing the sash can feel like a small irritation – until it leaves a ground-floor room vulnerable or lets in a draught. Well-fitted window locking systems are a key part of home security, but they also affect how easily your windows open, close and ventilate. The right answer is not always a complete replacement. Sometimes a professional adjustment, new handle or replacement lock is all that is needed.
How window locking systems work
Most modern uPVC and aluminium casement windows use a locking mechanism within the frame rather than relying on the handle alone. Turning the handle moves a concealed metal strip, often called an espagnolette or multipoint lock. This engages locking points around the edge of the opening sash and pulls it tightly against the frame.
The more accurately the sash meets the frame, the better the lock can do its job. A secure window should close smoothly, with no need to lift, push hard or force the handle. When it is locked, the sash should sit evenly against its seals, helping to keep out cold air, rain and outside noise as well as unwanted entry.
The handle is the part you see and use every day, but it is only one piece of the system. A key-locking handle can prevent the handle being operated from inside if glass is broken nearby, while the internal mechanism and locking points provide the main resistance when the window is shut. If the mechanism is worn, damaged or badly aligned, fitting a new key handle alone will not solve the underlying problem.
Common types of window locking systems
The lock fitted to your window depends on its style, age and material. Older windows often use different parts from modern replacements, so it is worth identifying the existing arrangement before ordering a repair.
Espagnolette and multipoint locks
These are widely used on modern uPVC and aluminium casement windows. The handle operates a gearbox, which moves locking points along a metal rail. Depending on the window, those points may be mushroom cams, rollers, bolts or hooks that engage with keeps fixed to the frame.
This arrangement offers strong, even closure across the sash. It also means that poor alignment can affect more than one point at once. A window that catches at the top, leaves a gap on the hinge side or needs a sharp lift before it locks may need its hinges, keeps or sash position adjusted.
Locking window handles
A locking handle is a familiar and useful feature, particularly on accessible windows. It normally has a small key cylinder at the base of the handle. The key should be kept somewhere safe but accessible to the adults in the household, rather than left in the handle all the time.
Handle styles and spindle lengths vary, especially on older uPVC windows. A handle that looks similar may not operate the mechanism correctly, so measuring and matching the part matters. This is one reason a repair visit can be more straightforward than trying several off-the-shelf options.
Sash locks and catch systems
Sliding sash and vertical slider windows commonly use sash fasteners or catches where the two sashes meet. These are designed to hold the window closed, and some versions include a key-operated feature. They can be highly effective when fitted correctly, but they need to be paired with sound frames, well-maintained cords or balances, and a sash that closes squarely.
Restrictors and ventilation catches
Window restrictors limit how far a window opens. They are particularly helpful in upper-floor rooms, homes with young children, and properties where a wide opening creates a safety concern. A restrictor is not a replacement for a main lock, but it can provide useful control when ventilation is needed.
Some windows also have a night-vent position, allowing a small gap while the sash remains partly engaged. Whether this is suitable depends on the location of the window. It may be practical on an upper floor, but it is rarely a sensible security choice for an easily reached ground-floor window.
Security is not just about the number of locks
It is easy to assume that more locking points automatically mean better security. In practice, the whole installation matters. Strong locking hardware is only as effective as the frame, glazing, hinges and fitting around it.
For example, a window with a good multipoint lock can still be compromised if the sash is loose, the hinges are worn or the frame has moved over time. Similarly, double glazing improves comfort and efficiency, but the glass specification and its installation are separate considerations from the lock itself.
For replacement windows, homeowners may wish to ask about security testing and specifications appropriate to their property. A reputable installer should explain the options plainly, including what is included as standard and where an upgrade would offer a genuine benefit. There is no need to pay for features that do not suit the window position or how you use the room.
Signs your window locks need repair
Locks rarely fail without warning. Paying attention to small changes can prevent a window becoming stuck open, difficult to secure or damaged by repeated forcing.
Common warning signs include a stiff handle, a handle that spins freely, a key that will not turn, scraping when the window closes, or locking points that do not engage. You may also notice draughts around one side of the sash, even when the handle is fully down. This can point to alignment issues rather than a failed lock.
Avoid forcing the handle. Excess pressure can break the internal gearbox, strip the handle spindle or damage the keeps on the frame, turning a manageable adjustment into a larger repair. If the window will not lock, close it as securely as possible, avoid leaving the property unattended where practical, and arrange for it to be inspected.
Condensation and general wear can also affect older mechanisms. Dirt in the tracks, paint on moving parts, tired hinges and lack of lubrication all make a lock work harder than it should. A professional can identify whether the mechanism can be adjusted and serviced, or whether a replacement part is the safer long-term option.
When to repair and when to replace
A repair is often the sensible choice when the frames and glass are in good condition. Replacing a faulty handle, gearbox, lock rail, hinge or set of keeps can restore secure operation without the disruption and cost of replacing the full window.
Replacement becomes more worth considering when problems are repeated, frames are distorted, double-glazed units have failed, or the windows no longer provide the comfort, appearance or security you need. If several windows are the same age and have similar faults, comparing the cost of individual repairs with a planned upgrade can help you make a clearer decision.
For older properties, the style of the window matters too. A repair may preserve the character of traditional sash windows, while a carefully chosen replacement can improve thermal performance and everyday ease of use. There is no one-size-fits-all answer – the right route depends on the condition of the existing windows and what you want from them.
Simple care that helps locks last
Window locks benefit from light, regular attention. Keep the frame channels and locking points free from grit, especially after building work or windy weather. Clean the moving metal parts with a soft cloth and use a suitable light lubricant sparingly where recommended. Avoid heavy oils that attract dirt or products that may affect uPVC surfaces and seals.
Open and close each window occasionally, including those in less-used rooms. This helps you spot changes early and makes sure the key, handle and mechanism still operate as expected. If a key is difficult to turn, do not keep trying with force. The issue may be the cylinder, the handle or pressure from a misaligned sash.
Get the lock and the fitting right
Security upgrades work best when they are chosen around the individual window, not picked from a generic shelf. The window type, its location, the age of the frame and the condition of the hinges all affect the suitable repair or replacement.
A proper survey should look beyond the visible handle. At Pearson Glazing, the aim is to give straightforward advice on whether a window can be repaired, adjusted or replaced, without pressure to choose more work than is necessary. For homeowners in south-east London and Kent, this can mean a practical route back to windows that close cleanly, lock properly and give reassurance every time you leave the house.
If a window is stiff, loose or no longer secure, dealing with it early is usually simpler than waiting for the lock to fail completely. A clear assessment from an experienced glazing professional can turn an everyday worry into a straightforward repair decision.

A lock that needs a hard shove, a lifted handle or several attempts with the key is more than an everyday annoyance. It can leave a door difficult to secure and, in some cases, difficult to open when you need it. The good news is that many homeowners can fix sticking locks with a few careful checks. The key is to establish whether the problem is in the lock itself, the key, the handle or the way the door or window is sitting in its frame.
Do not force a stiff key or lean your full weight on a handle. A little resistance can quickly become a snapped key, damaged cylinder or broken multi-point locking mechanism. Start gently, and arrange a repair if the lock feels close to failing.
First, work out when the lock sticks
The timing of the problem tells you a great deal. If the key turns easily while the door is open but sticks once the door is shut, the lock is often sound and the door is out of alignment. This is common with uPVC doors, composite doors and patio doors, particularly after a change in temperature or following years of regular use.
If the key is difficult to insert or turn whether the door is open or closed, look first at the key and cylinder. A worn key, dirt inside the keyway or a tired cylinder may be the cause. If you have a spare key, try it. A spare that works smoothly usually means the everyday key is worn and should be copied before it gets worse.
For doors with a lift-to-lock handle, notice whether the handle becomes difficult to lift before you turn the key. That points towards the keeps, hinges or door alignment rather than the euro cylinder. On a window, a stiff handle may indicate that the espagnolette mechanism is binding, or that the sash is not closing squarely against the frame.
How to fix sticking locks safely
Begin with the least invasive checks. Wipe the key clean with a dry cloth and inspect it for bent teeth, cracks or obvious wear. Never use a bent key in a lock. It may turn once, then break inside the cylinder.
Next, use a lock lubricant made for cylinders. A dry PTFE lubricant or graphite-based product is usually a sensible choice. Apply a small amount into the keyway, insert the key and turn it gently a few times. Wipe away any excess. Avoid cooking oil, grease and household oils. They can feel helpful at first but attract dust and grit, leaving the lock stickier over time.
If the handle or moving parts are stiff, use a light silicone or PTFE lubricant on the accessible moving points of the mechanism. Keep lubricant away from painted finishes and clean any drips promptly. On older timber doors, check that paint has not built up around the lock edge, latch or strike plate.
After lubricating, test the lock slowly with the door open. Lift the handle where required, turn the key, release it and repeat. If it now works freely open but catches when closed, stop focusing on the cylinder. The next step is to check alignment.
Check the door and frame alignment
Close the door without locking it and look at the gaps around the edges. An uneven gap, a door that rubs on the frame, or a latch that does not meet its keep cleanly can all create resistance. You may also notice that lifting the door slightly by the handle makes the key turn. That is a strong sign that the door has dropped or shifted.
Changes in weather can make this more noticeable. uPVC and composite doors expand slightly in warmer conditions, while timber can swell in damp weather. A minor seasonal adjustment may be all that is needed. However, recurring sticking should not be ignored, especially on an external door that protects your home.
Some modern hinges have adjustment points, but the correct adjustment depends on the hinge type and the door system. Small alterations can make a real difference; incorrect ones can worsen the fit or affect weather seals. If you are unsure, it is safer to have the door assessed rather than repeatedly adjusting screws at random.
With multi-point locking doors, the keeps on the frame may also need adjustment. These are the parts that receive the hooks, rollers or bolts when you lift the handle. If the locking points are scraping or failing to engage cleanly, forcing the handle can damage the gearbox inside the door.
Look for signs of a failing lock mechanism
A sticky lock is not always a lubrication or alignment issue. Be alert for a loose or floppy handle, grinding noises, a key that spins without operating the lock, or a handle that will not return to its normal position. These can indicate a worn gearbox, faulty spring cassette, damaged cylinder or failing multi-point mechanism.
If the door will lock only after repeated attempts, arrange a repair soon. Waiting until it will not lock at all can create a security issue, while waiting until it will not open can leave you locked out. In many cases, a professional can replace the affected part without replacing the whole door.
The same principle applies to windows. If a casement window handle will not turn, do not force it. The internal locking strip may be jammed, the handle spindle may be worn, or the window may have dropped slightly. A repair can often restore safe operation and security without the cost or disruption of a new window.
Common mistakes that make sticking locks worse
It is tempting to spray a generous amount of general-purpose oil into a lock and hope for the best. This may provide a brief improvement, but it is rarely a long-term fix. Thick or oily products hold dirt inside the cylinder and can leave the keyway clogged.
Another common mistake is continuing to use a key that has started to bend or catch. Keys wear gradually, so the change can be easy to miss. Replacing a worn key early is simpler than dealing with a broken one inside the lock.
Finally, avoid removing the cylinder or dismantling a multi-point mechanism unless you know exactly what you are doing. On a locked or closed door, this can make access more difficult. It can also leave the property unsecured if the replacement part is not the correct size or specification.
When to call for a lock repair
A professional repair is the sensible option if lubrication has not helped, the door needs lifting to lock, the handle is loose, or the key is showing signs of sticking and catching. It is also worth arranging an inspection after a break-in attempt, if the lock is visibly damaged, or if you are worried about the security of an older cylinder.
For homeowners in South East London and Kent, Pearson Glazing can assess problems with door and window locks, handles and mechanisms as part of a straightforward repair service. A proper inspection identifies whether the issue is a simple adjustment, a replacement cylinder, a handle repair or a fault within the locking mechanism. That means you pay for the work that is needed, rather than being pushed towards a replacement door.
Keep testing the lock gently after any adjustment or repair, both open and closed. A secure door should close without a fight, the handle should operate smoothly and the key should turn without excessive pressure. Addressing small changes early is one of the easiest ways to protect your home and avoid a lock failing at the most inconvenient moment.

A window quote can look good on paper, yet the fitting experience is where homeowners find out what a company is really like. South East window installer reviews are useful because they show how people felt about the whole job: the first enquiry, the survey, the installation, the finish and the support afterwards.
For a purchase that affects your home’s warmth, security and appearance, it makes sense to look beyond a star rating. The most helpful reviews give you a clear idea of whether the company communicates well, turns up when promised and deals fairly with questions or unexpected issues.
What South East Window Installer Reviews Can Tell You
A collection of genuine reviews should help you picture the customer journey, not simply confirm that a firm has completed jobs. Look for comments about the people involved. Were they helpful without being pushy? Did the surveyor explain the options in plain English? Were the fitters respectful of the property and tidy at the end of the day?
These details matter because replacement windows and doors are not off-the-shelf purchases. Every opening is different, and even a straightforward installation can involve practical decisions about trims, existing brickwork, internal finishes or access. A good installer keeps the customer informed rather than leaving them to chase for answers.
Reviews are particularly valuable when they mention the type of work you need. Someone replacing timber-style vertical sliders may have different priorities from a homeowner choosing aluminium bi-fold doors or repairing a misted double-glazed unit. Relevant feedback can tell you more than a general comment such as “great service”.
It is also worth checking whether customers describe a job completed over time. A review written after an installation is useful, but one that mentions how the windows, locks or doors have performed months later gives extra reassurance about workmanship and aftercare.
Read Beyond the Overall Rating
An excellent average rating is encouraging, but it should be the start of your research rather than the end. Read a sensible spread of recent reviews and look for repeated themes. If several customers independently mention clear communication, careful fitting and a clean finish, that usually says more than one especially enthusiastic comment.
Pay attention to how specific the wording is. A review that explains the scope of work, such as replacing front windows, fitting French doors or resolving a lock problem, is often more useful than a short rating with no context. Specific reviews tend to reveal whether a company handles both larger home improvements and smaller repair work with the same care.
You should also consider the age of the reviews. A business can change its team, processes or workload over time. Recent feedback is usually the best guide to what you can expect now, although a consistent record over several years is a good sign too.
A small number of mixed reviews is not automatically a reason to walk away. Home improvement work can be disruptive, and even well-planned jobs occasionally uncover issues once old frames are removed. What matters is whether the installer takes responsibility, communicates promptly and works towards a fair solution.
The Questions Good Reviews Answer
When reading reviews, keep your own project in mind. You are not just trying to decide whether people liked the company. You are trying to find out whether they are likely to be a good fit for your home and expectations.
Useful reviews often answer a few practical questions. Did the quotation match the final price, aside from agreed changes? Was the survey thorough enough to avoid surprises on fitting day? Did the installation team protect the working area and remove old frames and glass properly? Were dates confirmed clearly, and did the team explain any unavoidable changes?
For windows and external doors, look for comments on the finished result as well. Customers may mention quieter rooms, fewer draughts, easier opening and closing, improved security or a noticeable change in the look of the property. Those outcomes are often what homeowners want most, but they depend on accurate measuring and careful installation as much as the product itself.
If you need repair work, reviews can help you identify whether a company is willing to assess the problem rather than pushing straight for a full replacement. A failed sealed unit, worn handle or faulty lock may sometimes be repaired without replacing an entire window or door. Honest advice on this point can save both money and unnecessary disruption.
Watch for a No-Pressure Approach
Double glazing has a long-standing reputation for high-pressure sales visits. Homeowners are understandably wary of time-limited discounts, lengthy presentations and repeated follow-up calls. Reviews can be very revealing here.
Look for comments that describe a straightforward quotation process, clear explanations and time to make a decision. A professional installer should be happy to discuss materials, glazing options and likely costs without making you feel rushed. You may need time to compare styles, consider your budget or speak with other people in the household. That is normal.
There is a balance to strike. A company should be available to answer questions and follow up on a quote, but it should not make you regret asking for one. Reviews that mention a calm, helpful approach are often a strong indicator of how the business treats customers from the outset.
At Pearson Glazing, the aim is to keep the process practical and customer-led, with experienced fitters who also survey work. That can reduce the gap between what is discussed at quotation stage and what happens on site, while giving you a direct route to useful advice.
Use Reviews Alongside a Proper Quote
Reviews are valuable, but they cannot replace a detailed survey and written quotation. Two properties on the same street may need different solutions because of frame condition, opening sizes, building details or the homeowner’s priorities. The lowest figure is not always the best value if it leaves out finishing work, security features, glass specifications or removal of old materials.
Ask for the quote to explain what is included. For example, it should be clear whether the price covers surveying, supply, installation, trims, making good where agreed, waste removal and any relevant guarantees. If you are comparing uPVC and aluminium windows, or deciding between a composite and PVC-u door, make sure the specifications are genuinely comparable.
A good company will explain the trade-offs without jargon. Aluminium can offer slim sightlines and a contemporary appearance, while uPVC can be an excellent, cost-effective choice for many homes. A composite door may suit someone seeking a solid entrance door with strong kerb appeal, whereas a repaired lock or replacement panel may be all that is required in another case.
Reviews tell you how previous customers felt about the service. A survey and quote tell you what your own job will involve. Together, they are a far safer basis for a decision than a headline price or a glossy brochure alone.
A Sensible Way to Compare Local Installers
Start with a few installers whose service area covers your home in south east London or Kent. Read their recent reviews, then narrow the field based on the issues that matter to you: communication, workmanship, cleanliness, price clarity and aftercare.
Once you have spoken to them, notice whether the conversation matches the feedback. Are your questions answered directly? Do they ask sensible questions about your property? Do they explain the likely next steps? A review may bring a business to your attention, but your own contact with the team should confirm whether you feel comfortable proceeding.
Do not be afraid to ask how they would deal with a problem after installation. No homeowner wants to expect an issue, but knowing there is a clear route for adjustments or repairs is reassuring. The best installers do not disappear when the fitting is complete.
Your windows and doors should serve your home well for years. Take the time to read real experiences, ask for a clear quotation and choose the installer that gives you confidence before any work begins.

French doors are often chosen for the view they create into a garden, conservatory or patio. That glass and opening space should feel welcoming, not like a weak point in the home. Secure French doors can provide the light, access and traditional appearance people want, while giving you confidence that the doors are properly designed, fitted and locked.
The key is to look beyond the handles. Door security is not one feature you can add at the end. It comes from the frame, the locking system, the glass, the hinges and the quality of installation working together.
What makes French doors secure?
A well-made pair of French doors has two opening panels that meet in the middle. One is usually the main traffic door, operated by the handle, while the other is held in place by shoot bolts. When both panels are closed and locked, the pair should form a firm, aligned barrier rather than two doors that can be pushed or flexed apart.
For most homes, modern uPVC or aluminium French doors offer a considerable security improvement over older units. Their frames are designed to work with multi-point locking, reinforced areas where needed and modern double-glazed units. Composite-style door systems may also be an option where a more solid entrance-door appearance is preferred, although the best choice depends on the opening, the look of the property and how the doors will be used.
Security should never mean a door is awkward to live with. A good installation gives you an easy handle action, smooth opening panels and a positive lock, without gaps, sticking or rattling in windy weather.
Secure French doors start with the lock
The lock is naturally a major consideration, but it is the whole locking arrangement that matters. Most modern French doors use multi-point locking on the main door. Turning the handle engages locking points along the edge of the sash before the key is used to secure the cylinder.
These points may include hooks, bolts or rollers depending on the door system. Hooks can help resist attempts to force the door open, while bolts provide a firm connection between the sash and frame. The important point is that the lock engages cleanly and fully into properly fitted keeps in the frame.
Choose a suitable cylinder
On doors with a euro-profile cylinder, the cylinder should be appropriate for the level of security required and fitted to the correct length. A cylinder that protrudes too far beyond the handle can be more vulnerable to attack, while one that sits too deeply can be difficult to operate.
Anti-snap cylinders are a sensible upgrade for many external doors. They are designed so that, if force is applied, the outer section breaks in a controlled way while the internal locking mechanism remains protected. They are not a substitute for a sound door and frame, but they are a worthwhile part of a wider security specification.
If you have an existing set of French doors that is otherwise in good condition, replacing worn locks, cylinders or handles can be a practical option. A professional assessment can establish whether a repair will give you the security you need or whether the condition of the doors points towards replacement.
Do not overlook the second door
The inactive panel is just as important as the main opening door. It is normally secured by top and bottom shoot bolts that locate into the head and threshold of the frame. These should be strong, easy to operate and properly aligned.
Loose or damaged shoot bolts can leave a pair of doors less secure even if the main lock is working perfectly. They should also be checked after any movement in the property, a door adjustment or signs that the panels are catching.
Glass needs to be part of the decision
French doors have large glazed areas, which is one reason they are so popular. It also means the glass specification deserves more thought than it sometimes receives.
Toughened safety glass is commonly used in doors because it is designed to break into small, less dangerous pieces if it fails. Laminated glass offers a different benefit: an interlayer holds the glass together after breakage, making it more difficult to create an opening quickly. For doors in a more exposed location, or where security is a particular concern, laminated glass may be worth discussing.
There is a trade-off. Different glass specifications can affect cost, weight and, in some cases, the appearance of the unit. Frosted or patterned glass can add privacy, but it is not automatically a security upgrade. The right choice should balance privacy, safety, insulation and the way your home is used.
Fitting is as important as the product
Even high-quality secure French doors will not perform as intended if they are poorly fitted. The frame must be fixed securely to the structure, level and square, with the sashes adjusted so that locks and bolts engage correctly.
A door that needs to be lifted to lock, catches on the threshold or leaves uneven gaps is not simply inconvenient. It may indicate that the locking points are under strain or not fully engaging. Over time, this can lead to wear and can make the door easier to force.
Good fitting also protects weather performance. Draughts, water ingress and movement can all affect how a door closes and locks. This is why surveying the opening properly before installation matters. At Pearson Glazing, fitters also survey work, helping to keep the advice practical from the first measurement through to installation.
Security features worth asking about
When comparing French doors, it helps to ask clear questions rather than relying on a broad claim that a door is “secure”. The following features are useful indicators of a considered specification:
- Multi-point locking that engages along the main opening door.
- Secure top and bottom shoot bolts on the second door.
- A correctly fitted, quality security cylinder, with anti-snap protection where suitable.
- Toughened or laminated safety glass matched to the location and your priorities.
- Reinforced sections where the door system requires them.
- Security-tested hardware and a professional installation with final adjustment.
You may also want to ask whether the proposed doors meet recognised security standards or are suitable for a particular insurance requirement. Standards can be useful, but they should not become a confusing sales point. What matters is that the specification suits your property and is installed properly.
Everyday habits still matter
A secure door needs to be used as intended. Simply pulling French doors shut may not engage the multi-point lock. Lift the handle fully, turn the key and remove it from the lock, particularly when leaving the house or going to bed.
Avoid leaving keys in the inside cylinder where glass close to the handle could allow someone to reach through after breaking a pane. The best arrangement depends on the door layout and household needs, including how quickly people need to leave in an emergency. If there are children, older relatives or anyone who may need easy access, discuss the options rather than choosing a locking style on security alone.
Regular maintenance makes a difference too. Keep tracks and thresholds free of grit, check that handles feel firm, and arrange an adjustment if the doors begin to drop or become difficult to lock. There is no benefit in waiting until a lock fails completely.
When replacement is the sensible option
Repairs can often extend the life of French doors, especially where the issue is a worn cylinder, faulty handle, misted glass unit or misalignment. Replacement becomes more attractive when the frame is damaged, the doors have significant movement, the locking system is obsolete, or repeated repairs are no longer delivering a reliable result.
Older French doors may also have single glazing, basic handles and limited locking points. Replacing them can improve security, warmth and day-to-day operation in one project. For homeowners in South East London and Kent, a straightforward survey can clarify whether adjustment, repair or replacement is the better value route.
The best French doors should not make you choose between a bright home and a secure one. Ask for a clear explanation of the locks, glass and fitting method, then choose a solution that feels right for your property and the people who use it every day.

A cold line around the edge of a window is more than an annoyance when the heating is on. It can make a room feel uncomfortable, raise energy use and leave you wondering whether the whole window needs replacing. The good news is that, to prevent window draughts, the first step is usually to find where the air is actually getting in. Many problems can be repaired without replacing every window.
Start by finding the source of the draught
Not every cold area near a window is a draught. Glass naturally feels cooler than an insulated wall, especially on a winter morning. A genuine draught is moving air, often felt around the opening sash, the frame, the handles or where the frame meets the wall.
On a still day, run the back of your hand slowly around the inside edge of the window. Pay particular attention to the corners, opening sections and the area beneath the sill. You may also notice curtains moving slightly, a whistling sound in windy weather, or a visible gap in old sealant.
It helps to check these common areas:
- Worn or flattened rubber seals around opening windows
- Window handles, hinges and locks that no longer pull the sash tightly closed
- Gaps or failed sealant between the frame, sill and brickwork
- A poorly fitted replacement unit or an older timber frame that has warped
- Door and window junctions, particularly around patio doors and French doors
If the draught seems to come through the middle of the glazed unit rather than around its edges, the issue may be poor insulation from older single glazing or an ageing double-glazed unit. That calls for a different solution than replacing a seal.
Simple ways to prevent window draughts
A few practical checks can make a noticeable difference, particularly when the window itself is still in good condition. Start by making sure the window is properly closed and locked. On many modern uPVC and aluminium windows, engaging the handle fully helps draw the sash against the seals.
Clean the seals with warm, soapy water and a soft cloth, then dry them carefully. Dirt, paint residue and debris can stop a window from closing as closely as it should. Avoid harsh cleaners or petroleum-based products, as these can damage rubber over time.
For small gaps around an opening sash, replacement weather seals can be effective when they are the correct size and profile. A seal that is too thick can make the window difficult to close; one that is too thin will not stop the airflow. It is worth identifying the existing seal type before buying a replacement rather than applying a generic strip over the top.
Gaps around a fixed frame can often be resealed externally or internally, depending on their location. Cracked silicone, shrinking mastic and failed pointing around a sill are common on older installations. This work needs a clean, dry surface and the right sealant for the material. Simply covering over loose or split sealant rarely lasts.
Temporary draught excluder tape can be useful during a cold spell, but treat it as a short-term measure. It can look untidy, leave residue and may hide a fault that needs proper attention.
Do not block planned ventilation
Trickle vents are designed to provide background ventilation. They can feel cold when open, but blocking them completely can increase condensation, mould and stale air, especially in bedrooms and kitchens. If a vent is noisy, damaged or excessively draughty, it is better to have it assessed than permanently sealed.
The same applies to extractor fans and air bricks. A comfortable home needs controlled ventilation as well as good seals. The aim is to stop unwanted air leakage around the window, not to make the property airtight in the wrong places.
When hinges, handles or locks are the real problem
A window can look closed while still sitting slightly away from its seals. This is particularly common with older casement windows where hinges have worn, dropped or become restricted by dirt. You might find that the gap is worse at the top or bottom corner, or that you need to push hard on the frame before the handle will lock.
In some cases, an experienced repairer can adjust the hinges, realign the sash or replace worn locking components. New hinges, handles or keeps may restore the closing pressure and make the window easier to use at the same time.
Do not force a stiff handle. Excess pressure can damage the gearbox or lock mechanism, turning a relatively straightforward adjustment into a larger repair. If the handle is difficult to turn, the sash is catching, or the lock does not engage cleanly, arrange for it to be checked.
Check the glazing and the installation, not just the seals
Double glazing reduces heat loss, but it does not last forever. If you can see mist or moisture between the panes, the sealed unit has failed. This does not usually create a draught in the same way as a gap around the frame, but it does reduce insulation and can make the room feel colder.
Where the frame remains sound, replacing only the glazed unit can be a sensible, cost-effective option. It avoids unnecessary disruption and can improve warmth and clarity without changing the whole window.
The installation around the frame matters just as much. A draught at the edge of a window may be caused by a gap between the frame and the wall, failed exterior sealant, or poor insulation around the opening. These faults need to be diagnosed properly because the visible gap indoors is not always the point where water or air is entering.
Older properties can add another layer of complexity. Uneven brickwork, timber movement and original reveals may mean a repair needs a more considered approach. Filling every gap with expanding foam is not a reliable answer and can make future maintenance difficult.
Repair or replace: how to make the right call
Repair is often the sensible first option when the frame is in good condition and the problem is limited to seals, hinges, locks, handles or glazing units. It is usually less disruptive and can extend the life of windows that still perform well overall.
Replacement becomes more worthwhile when there are several issues at once: persistent draughts from multiple areas, warped or damaged frames, recurring condensation between panes, poor security, difficult operation or single glazing throughout the property. New windows can improve thermal performance, comfort and noise reduction, but their benefits rely on careful surveying and fitting.
A professional inspection should explain what is wrong, what can be repaired and where replacement would offer better long-term value. There should be no need for guesswork or a rushed decision based on a sales pitch.
Prevent draughts from returning
Once a window is repaired or replaced, a little regular care helps keep it working properly. Clean the tracks and drainage channels so water and debris do not build up. Wipe seals occasionally, check that handles lock smoothly and look for cracks in external sealant before winter arrives.
