This guide walks you through exactly how to adjust uPVC windows step by step, covering horizontal alignment, vertical sash correction, and contact pressure tuning. Learn how to diagnose the specific issue, which tools you need, and crucially, when to stop and call for professional help or when your windows need replacing.

Essential Tools and Preparation for uPVC Window Adjustment

Before you make any adjustments, gathering the right tools and understanding your window hardware will save you time and prevent damage.

• 4mm Allen key – this is the most common size across UK window manufacturers and is needed for adjustable window hinges.
• Phillips head screwdriver – commonly used for hinge adjustments, and top-hung windows need a screwdriver for friction stay adjustments.
• Spanner – this may be required for casement windows for nuts and bolts, depending on the hardware fitted.
• Spirit level – essential for checking window alignment after adjustments
• Soft cloth and mild soapy water – should be used to clean adjustment points before you begin.
• Silicone-based lubricant – friction and stiffness in uPVC windows may be caused by dirt and dry mechanical parts, so applying silicone-based lubricant to moving parts improves operation of uPVC windows and should be part of your preparation.

Important Safety Considerations

Older uPVC windows with cracked or split frames may not hold adjustment screws securely, and forcing hardware into compromised material can cause further damage. If your windows are under warranty, check whether DIY adjustments are permitted, as incorrect modifications could void your coverage. Look for plastic caps on your window hinges; these typically conceal the adjustment screws beneath. Brands like ERA, Mila, and Yale commonly feature documented adjustment ranges. If you remove these caps and find no adjustment screws, your hardware is likely non-adjustable, and you’ll need professional assistance or replacement hinges.

Step-by-Step uPVC Window Adjustment Methods

There are three principal types of adjustment you can make to uPVC windows: horizontal (side-to-side), vertical (up/down), and compression (how tightly the sash presses against the frame seal). Common symptoms of uPVC window issues include catching on the frame and difficulty locking. Incorrect alignment causes uPVC windows to stick when opening, while gaps between the window and frame can lead to draughts. Adjusting uPVC windows can fix draughts and ensure smooth opening and closing, improving both energy efficiency and security.

To identify which adjustment you need, close the window completely and run a thin strip of paper around the edge where the sash meets the frame. Consistent resistance indicates a good seal; any loose spots reveal where the problem lies. You can also try the candle test, which can help identify draught spots-hold a lit candle near the window edges on a windy day and watch for flickering. Use a spirit level to check whether the sash is sitting level, and open and close the window several times to observe exactly where rubbing or sticking occurs.

Horizontal Adjustment for Sticking and Misaligned Windows

When your window sash is rubbing against one side of the window frame, horizontal adjustment is needed. Open the window completely to access the hinge adjusters. On side-hung casement windows, locate the adjustment screws on the hinge leaf where the sash meets the frame. Use a 4mm Allen key for hinge adjustments.

If the sash is catching at the top on the lock side, adjust the top hinge first. The adjustment screw for the hinge can be turned clockwise or counter-clockwise. Turning the hinge clockwise typically pulls the sash towards the hinge side, while turning anti-clockwise pushes it towards the other side. Make small adjustments of roughly a quarter turn at a time, then close the window to test whether it moves in the right direction. If the bottom edge is rubbing, repeat the process on the bottom hinge. The typical horizontal adjustment range is ±3–4 mm, so if your misalignment exceeds this, further adjustments won’t help and the hinges may need replacing.

Vertical Adjustment for Dropped Window Sashes

A dropped sash is a common problem with uPVC windows, particularly on larger or heavier units. Dropped sashes can open gaps between the frame and sash, allowing cold air in and causing heat loss. Adjusting hinges can resolve dropped or misaligned sashes in uPVC windows.

For side-hung windows, locate the vertical adjustment screw, usually hidden under a plastic cap on the hinge. Using your Allen key, turn the screw clockwise to raise the sash or anti-clockwise to lower it. The typical vertical adjustment range is around ±2–3 mm. Ensure you adjust both the top and bottom hinge position equally to keep the sash properly aligned across its full height.

Adjust top-hung windows by tightening screws under the friction stay. If the friction stay has lost tension and the window won’t stay open at the desired angle, locate the tension screw on the stay arm and tighten it. After each adjustment, close the window and check that the gap spacing between sash and frame is even all the way around. Loosen screws to reposition the window for better alignment if needed, then retighten once the sash sits correctly.

Lock Mechanism and Contact Pressure Adjustment

When the window lock is stiff or engages poorly, the locking mechanism and contact pressure likely need attention. If uPVC windows are not sealing properly, adjustments can often improve the situation. Most modern uPVC windows have mushroom cams for adjusting compression and seal pressure-these are the oval or mushroom-shaped rotating components on the edge of the sash that engage with strike plates on the frame.

Adjustments to the locking cam pressure should be made in small increments. Turn the cams to increase or decrease how tightly the sash compresses against the rubber seals. Adjusting the locking cams can increase winter weather tightness in uPVC windows, helping to stop draughts and create a tighter seal. The compression adjustment range is typically ±0.5 mm to ±1.5 mm. The handle of a properly adjusted uPVC window should engage with firm resistance-not so tight that you struggle to turn it, but firm enough to create a better seal against the frame. Small adjustments to uPVC windows should be tested frequently for effectiveness; close and lock the window after each quarter turn to check the result.

If the lock still won’t catch after hinge and cam adjustments, you may need to adjust window locks by repositioning the strike plate. Loosen its fixing screws, shift the plate slightly, and retighten. Misaligned hinges can cause gaps and draughts in windows, so always verify hinge alignment before assuming the lock itself is at fault. Damaged rubber seals reduce a window’s ability to form a tight seal, and no amount of compression adjustment will compensate for perished or flattened seals and will therefore need replacing.

Professional Help vs DIY Solutions

While minor adjustments to uPVC windows are well within the capabilities of most homeowners, there are clear limits to what DIY can achieve. If adjustments do not fix issues, worn hinges or seals may need replacement, which may require professional tools and expertise. Understanding when to call in help can save you money and prevent further damage.

Signs You Need Professional Window Repair

Contact a professional if you notice severely corroded or broken friction hinges, hinge pins that have sheared, or if the misalignment exceeds the ±3–4 mm adjustment range of standard hardware. Draughts can occur due to misalignment over time, but if you’ve worked through all the adjustment points and the window still won’t close smoothly or seal properly, the issue likely goes beyond what adjustment screws can resolve. Older windows, particularly those fitted before the mid-1990s, may have fixed butt hinges with no adjustment capability at all.

Signs You Need Complete Window Replacement

Some problems are beyond repair. Failed double glazing, visible as condensation or fogging between panes, cannot be resolved through alignment adjustments. Extensively warped or cracked window frames, obsolete hardware that’s no longer manufactured, and damaged rubber seals that have perished beyond replacement all point towards fitting new uPVC windows.

New A-rated energy-efficient windows offer significantly improved insulation, better security features, and lower maintenance requirements. Window replacements in England and Wales must comply with building regulations and should be carried out by FENSA-registered installers to ensure proper certification and compliance.

Conclusion

Most uPVC window problems – sticking sashes, draughts, and locks that won’t engage – can be resolved with a 4mm Allen key, a screwdriver, and 15 to 30 minutes of careful adjustment per window. Horizontal, vertical, and compression adjustments each address specific symptoms, and working through them methodically will restore your window’s ability to close properly and maintain a tight seal. Regular maintenance, ideally checked before winter and after periods of heavy weather, keeps everything functioning properly and prevents minor issues from becoming costly repairs.

The key is knowing your limits. If the frame is damaged, rubber seals are perished, or adjustments aren’t bringing the sash back into proper alignment, professional help offers better value than repeated DIY attempts. Whether you’re tackling the adjustment yourself or deciding it’s time for replacement, understanding how your uPVC windows work puts you in control of the decision.

Assess your windows today-check each one for draughts, sticking, and uneven gaps. For straightforward misalignment, the steps above will get your windows properly aligned and sealed. For anything more complex, get quotes from qualified window professionals who can advise whether repair or replacement is the smarter investment.

Broken window lock: what to do first

For most homeowners, a broken window lock looks like one of three things: the window handle turns but the sash will not open, the key will not move at all, or the handle is stuck in the closed position. All three of these problems are fixable.

Start with safety and security checks:

• A broken window lock can affect your home’s security. Intruders can force open a window with a broken lock in seconds, so double-check that ground-floor or accessible windows with faulty locks are not left unsecured overnight.
• A functioning window lock deters potential intruders. If the window is stuck open and will not lock, use timber wedges or a sash stop as a temporary secure measure until it can be repaired.
• If the issue is a jammed window lock on a closed window, focus on safe opening first. Do not force a stiff handle; excessive force can damage window locks, particularly the spindle or uPVC window gearbox inside.

Stop DIY immediately and call a professional if the window frame is visibly damaged, the glass is smashed, or if the window is a sole fire escape from an upstairs bedroom. uPVC window locks, espag strips, and multi-point locking mechanism systems can almost always be repaired or replaced independently of the full uPVC window.

Common signs and causes of a broken uPVC window lock

Most window lock problems start gradually. Signs of a failing window lock include stiff handles and misalignment that worsen over weeks before a complete failure. Common symptoms of a failing window lock include a loose handle or failure to engage when turning the key.

The basic anatomy of a typical espagnolette uPVC lock: the window handle turns a spindle, which rotates a gearbox (centre case) inside the sash edge. The gearbox drives a locking strip with mushroom cams or rollers that engage with keeps (strike plates) fixed to the window frame. Each locking point must meet its keep for the lock to secure the sash.

Common mechanical failures include:

• Worn gearbox teeth in older installations from 2005 to 2012, where zinc alloy components have reached their 15 to 25 year wear life.
• A broken key snapping inside the cylinder, blocking the barrel.
• Loose lock parts such as fixing screws backing out over time, allowing the handle to wobble and transfer damaging force to the gearbox.

Misalignment can prevent window locks from engaging properly. Sagging sashes cause misaligned locks where rollers no longer reach the keeps, mimicking a broken uPVC window lock even when internal parts are intact. Rust and corrosion can weaken window lock components, particularly in coastal locations or kitchens with high moisture exposure. Dirt and debris accumulation can jam window locking mechanisms on high-traffic windows that lack regular cleaning and lubrication. Common causes of broken window locks include wear and tear, corroded parts, repeated slamming, and thermal expansion of the plastic frame.

How to open a stuck or jammed uPVC window lock safely

Improper attempts to open a jammed lock can crack the sash, damage the frame, or shatter the glass. Patience and the right tools matter more than strength.

The approach differs depending on whether you have a loose, non-functioning handle (failed spindle) or a seized mechanism where nothing moves at all.

Step-by-step for a typical side-hung uPVC window:

1. Remove the handle by lifting the decorative caps and unscrewing the two fixing screws. Expose the spindle hole.
2. Test if the spindle turns the gearbox by inserting an allen key or flathead screwdriver into the square hole and rotating gently. If the gearbox responds, the problem is the handle or spindle, not the entire mechanism.
3. If the gearbox does not respond, use a bent allen key and needle nose pliers from inside to push back individual cams or shoot bolts along the locking strip. Protect the frame with a plastic or cardboard shim to avoid scratching.

Modern uPVC hardware often uses co-extruded seals that cannot be pulled out, so access the locking points by gently flexing the sash and using thin tools. Older windows with removable gaskets allow better visibility. To fix a failing lock, remove debris and clean locking points before assuming the mechanism is dead. Adjusting the alignment of the window can resolve locking issues where the sash has shifted slightly.

If the jammed lock will not release after these steps, a completely failed gearbox is the likely cause. At this stage, calling a specialist is the better option; forcing the mechanism risks cracking the frame.

DIY checks and repairs for broken uPVC window locks

Many issues (loose parts, misaligned locks, dirt-related jamming) can be addressed with basic tools. Structural damage and advanced uPVC hardware repairs should be left to professionals.

Standard toolkit for uPVC window lock work:

Tightening loose parts: Check handle screws behind the decorative caps. Tightening loose screws can enhance the security of window locks. A quarter-turn on each screw often removes handle play that would otherwise transfer damaging force to the gearbox.

Alignment check: Close the window slowly and watch where the sash meets the frame. Adjust keeps up, down, in, or out using their fixing screws until cams engage fully. Re-test the locking action.

Cleaning a jammed lock caused by dirt: Brush grit from the espag strip slots and keep holes. Apply a light silicone spray to the moving parts, work the handle to distribute it, then wipe off overspray with a clean cloth. Do not over-apply.

Broken key in the lock barrel: Grip any protruding fragment with needle nose pliers and pull straight out. Do not push the key further in. Graphite powder can help free a stuck fragment. If the broken piece is flush or deeper, a locksmith with extraction tools is needed.

A lock housing should be replaced if cracked or severely corroded. Any sign of cracked plastic around the handle base, deformation of the sash, or metal fragments from the locking mechanism indicates internal failure requiring replacement parts rather than further DIY attempts. Professional locksmiths can assess if a lock needs repair or full replacement. Replacement parts for window locks are often inexpensive and widely available. Most window lock repairs take 30 to 60 minutes in a single visit.

The post How To Fix A Broken Window Lock Easily appeared first on Cosyhomes Windows.

The good news: fixing and insulating draughty windows is one of the most cost-effective improvements you can make for home comfort. To stop draughts from windows, start by checking seals and gaskets for visible damage, apply draught-proofing strips or insulating window film for quick relief, and call a specialist like Cosyhomes Windows for professional repairs if the problem persists. Many draughty windows can be repaired rather than replaced, and sealing windows properly can save approximately £85 annually in energy costs.

In this article, we cover a range of solutions, including:

• Quick DIY fixes – foam tape, silicone sealant, window insulation film, thermal curtains, draft snake
• Semi-permanent upgrades – EPDM and brush strips, secondary glazing kit, hardware adjustments, trickle vents
• Professional repairs – seal renewal, hardware realignment, frame resealing, misted unit replacement
• Secondary glazing – for single-glazed and heritage windows
• Full window replacement – when repair is no longer viable

Spotting Draughty Windows: Signs, Tests, and Red Flags

Before choosing how to fix drafty windows, you need to pinpoint exactly where the air leaks are. A gap along the meeting rail of a sash window needs a completely different fix from a failed seal between the frame and the wall. Misidentifying the source often leads to wasted effort and money.

Practical at-home tests:

• Run the back of your hand slowly around the window on a windy day, and you’ll feel cold air where there are gaps
• Detect draughts using a candle or incense stick; hold it near the edges and watch for flame flicker or smoke drift
• If you have net curtains, check them with the window closed. If they move, air is getting through
• Listen for whistling or rattling during strong winds

Common symptoms of draughty windows:

• Cold spots on walls beside window panes or on the glass itself, even with heating on
• Visible gaps around window frames clearly indicate air leaks
• Rooms that never reach a comfortable temperature despite the heating system running
• Rising energy bills compared to previous winters
• Damp patches or mould forming on window reveals are a sign that cold surfaces are triggering condensation

Small air leaks vs major gaps:

• A tiny gap (under 2–3 mm) at the meeting rail or around a worn gasket may only produce a slight breeze. This can be detectable with a candle but easy to miss by hand
• A warped frame, missing seal section, or separation between the frame and the wall allows large, obvious airflow and significant heat loss
• Rattling sashes usually indicate the window can’t close properly or locking hardware has failed

Regular inspections of seals and caulk can help maintain window energy efficiency over time. If your DIY checks reveal persistent problems, take photos and notes of the affected areas to share with a professional.

Common Causes of Draughty Windows

Windows naturally degrade over 10–25 years. Materials shrink, seals erode, frames warp, and hardware loosens. Even relatively modern windows suffer if the original installation was poor or the materials were substandard.

Seals and gaskets:

• Rubber seals and EPDM gaskets crack or shrink due to UV exposure and temperature cycling. Older windows can lose effectiveness due to worn seals alone.
• Foam gaskets compress over time, losing their ability to rebound and fill the gap around the opening sash.

Frames ageing or warping:

• Timber window frames absorb moisture, dry out, and shrink at joints. Sagging sills create bottom gaps.
• Older uPVC and aluminium frames can warp, settle, or lose their existing window frames’ original shape, preventing a tight seal.

Perimeter sealant failure:

• The mastic between the external frame and brickwork can crack and separate, especially on properties built or refurbished in the 1980s–2000s. Small cracks here let both wind and water penetrate.

Hardware problems:

• Hinges, espagnolette locks, keeps, and handles that no longer align prevent the sash from compressing evenly against seals. Faulty seals are often actually faulty hardware.

Glass type:

• Single pane windows and original box sash windows with single-glazed window glass offer very little insulation (U-values around 5.5 W/m²K), even when frames are sound.

Poor installation:

• Poorly installed windows with twisted frames, uneven packers, or missing sealant are a frequent cause of draughts in builds from any era.

DIY Temporary Fixes: Fast Ways to Calm a Draught

These temporary solutions are ideal for renters, for bridging the gap before professional repair, or when you need to stop window drafts quickly during a cold snap.

• Self-adhesive draught excluder/foam tape: Stick foam or rubber-foam strips around the sash and frame perimeter. Make sure to match the strip thickness to the gap. If it is too thick the window won’t close properly, too thin, it’s ineffective. Self-adhesive foam strips last 1–3 years before needing replacement. Cost: roughly £2–£10 per window. Weatherstripping should fit snugly to prevent air from entering around window sashes.
• Silicone sealant or caulk: Applying silicone sealant can fill cracks and gaps around window frames, particularly where the frame meets masonry. Caulking can seal gaps between the frame and surrounding wall to prevent drafts. Use exterior-grade silicone and avoid covering drainage weep holes, as those prevent water build-up inside the frame.
• Insulating window film: Clear heat-shrink plastic film can serve as a temporary secondary-glazing barrier over single-glazed or very cold windows. Insulating window film can reduce heat loss by up to 30%. Cost: around £5–£20 per window. It can limit your ability to open the window and affects the view slightly.
• Heavy or thermal curtains: Hanging heavy thermal curtains can create a barrier against cold drafts. Floor-length curtains with a pelmet trap an extra layer of still air. Heavy thermal curtains can significantly reduce heat loss at low cost with no structural changes.
• Draft snake/draught stopper: A fabric tube placed along the bottom rail of an existing window or sill blocks cold air seeping under timber sashes. Cheap, easy to make or buy, but needs repositioning each time the window opens.

These are temporary fixes and not permanent solutions. Most reduce your ability to open the entire window freely.

Smarter Draught Proofing: Semi-Permanent Improvements You Can DIY

For homeowners willing to invest a couple of hours per window, these draught proofing measures offer a more permanent fix with better durability than basic tape and plastic film.

• Upgrade to EPDM, silicone bulb, or rubber seals: Replace cheap foam with P-, E-, or V-profile compression seals. These resist UV and temperature swings and last significantly longer. Silicone sealant can last 5–10 years when properly applied. Cost: £10–£20 per window in materials.
• Brush strips for sash windows: Fit brush pile weatherstripping along meeting rails, parting beads, and sliding edges. Brush strips can last 3–5 years and allow window movement without obstruction, which is essential for any opening sash.
• Controllable trickle vents: Rather than sealing off existing vents permanently, upgrade to adjustable models that let you control airflow. This helps manage moisture while keeping outside temperatures at bay.
• Replace perished gaskets and adjust hardware: Many uPVC and aluminium systems use standardised gasket profiles available by the metre. Reseat keeps and tighten locking points so the sash pulls firmly into the rubber seals when locked – this alone can fix faulty seals without replacing parts.
• Low-cost secondary glazing kit: Acrylic panel or magnetic strip systems clip inside the existing window reveal, creating an air gap of 50–100 mm. Interior storm window inserts improve insulation without blocking views. These lean towards a more permanent solution and require careful measurement of the existing window frames.

Addressing air leaks with these methods can reduce heat loss without full window replacement.

Professional Repairs: When to Call Cosyhomes Windows

Many draught issues that seem serious can actually be resolved through targeted professional repair rather than replacing the entire window. This is central to how Cosyhomes Windows approaches every job – repair first, replace only when necessary.

When to call a professional:

• Thick black mould or rotting timber around the window frame or sill
• Windows that won’t close properly due to frame distortion or broken locks
• Condensation trapped between double glazing panes is a clear sign of a failed seal in the sealed unit
• Visible frame movement or separation between the frame and the wall
• Underlying issues that keep returning after repeated DIY attempts

What Cosyhomes Windows can do:

• Replace misted or failed double-glazed units without changing the frame
• Renew rubber seals, EPDM gaskets, and brush pile around sashes and frames
• Re-align hinges, fit new handles, and adjust espagnolette locking points for correct compression
• Reseal frame-to-wall joints with colour-matched mastic for a clean finish
• Carry out a full draught assessment, checking frame distortion, seal compression, and pinpointing the precise source of air leaks rather than guessing

Professional air sealing can reduce energy waste by up to 45%, and professional draught-proofing provides a permanent seal for windows that DIY solutions simply can’t match. Repair can often be completed in a single visit for typical problems like faulty handles, misaligned hinges, or misted units. Visit the Cosyhomes Windows repairs page to find out more about professional solutions.

Secondary Glazing and Upgrades for Single Glazed Windows

Older single-glazed windows and original sash windows are particularly prone to draughts and poor energy performance. With U-values often around 5.5 W/m²K, even perfectly maintained single pane windows let far more heat escape than modern double glazing.

• What secondary glazing does: It adds a discreet inner layer of window glass or an acrylic panel on the room side, trapping an insulating air gap between panes. Secondary glazing can reduce heat loss by up to 60%.
• Temporary vs robust systems: Window insulation film using double-sided tape and plastic film is the cheapest option. More durable solutions include aluminium-framed sliding panels or magnetic strip systems that can be removed seasonally.
• Heritage suitability: Secondary glazing is often permitted in conservation areas and listed buildings where replacing the external window frame is not allowed, provided the system is reversible and non-destructive.
• Combined approach: Pairing secondary glazing with draught proofing on the original sash delivers much more complete performance, tackling both small gaps and overall thermal resistance.
• Cost perspective: Professional secondary glazing runs roughly £160–£700 per window depending on size and style, while DIY acrylic panels cost £50–£150. Cosyhomes Windows can advise whether secondary glazing or replacement windows represent the best route for your property type and budget.

When a Permanent Fix Means New Windows

While many draughty windows respond well to repair, some reach a point where a full window replacement is the only sensible long-term solution. Windows over 20–25 years old often need professional replacement, especially when frames are severely warped, timber is rotten beyond repair, or seals have failed repeatedly after multiple fixes.

Modern windows offer transformative improvements:

• A-rated double glazing or triple glazing with warm-edge spacers and low-e coatings
• Multi-chambered uPVC or thermally broken aluminium window frames that virtually eliminate cold bridging
• Flush sash, casement, or tilt-and-turn designs with multipoint locking for an airtight seal
• High-quality gaskets and adjustable hinges that maintain a tight seal for decades

Replacement windows are more expensive – typically £500–£1,500 each – but the energy savings, comfort gains, and improved home’s energy efficiency are substantial. Professional insulation can significantly improve energy efficiency across the whole property, and homeowners recover up to 84% of insulation upgrade costs at resale. Cosyhomes Windows will always survey your old windows and recommend repair versus replacement based on what’s genuinely most cost-effective.

Balancing Draught Proofing, Ventilation, and Condensation

Completely sealing windows isn’t the goal. You need to stop uncontrolled draughts while maintaining enough ventilation for healthy indoor air quality.

• Aggressive sealing of every gap can increase condensation on cold window glass if moisture from cooking, bathing, and breathing has nowhere to go – leading to mould, peeling paint, and timber rot.
• Never permanently block trickle vents or air bricks. Use them alongside draught proofing to maintain controlled background airflow.
• Use extractor fans in kitchens and bathrooms, open windows briefly after showers, and keep furniture clear of cold external walls.
• Cosyhomes Windows engineers consider both draught proofing and ventilation when recommending repairs, ensuring you don’t simply swap a draught problem for a damp problem.

The best permanent fix blends a tight seal around window frames with planned, controllable ventilation – energy-efficient comfort without the condensation risk.

Next Steps: Getting Your Draughty Windows Sorted

Draught proofing windows delivers noticeable comfort and measurable energy savings without always requiring new windows.

Your action plan:

• Inspect your windows for obvious issues – run the hand and candle tests, check for visible damage to seals, and note any small gaps or frame movement
• Apply safe temporary fixes – foam tape, insulating film, or thermal curtains for immediate relief this winter
• Book a professional assessment if draughts persist, if you spot mould, or if your windows are over 20 years old

Contact Cosyhomes Windows for tailored advice on repairs, secondary glazing, or replacement windows. You can request a survey or send photos of your draughty windows to get started.

With the right combination of DIY solutions, professional draught proofing, and – where genuinely needed – new windows, a warmer, more energy-efficient home is achievable for most properties. Save money, cut your energy costs, and cure drafty windows.
