Window repairs & maintenance

Not every tired window needs replacing. Well-targeted window repairs can cure draughts, sticky openers, misted panes and wobbly handles — bringing back warmth, quiet and smooth operation without the cost of full replacement. Our technicians diagnose problems quickly, complete uPVC window repair cleanly and advise honestly when a new unit would be the better investment. We also offer simple maintenance that keeps your windows performing year after year.

Good repair work is about detail: correct parts, square alignment, neat sealing and careful testing. With those handled, you’ll feel the difference the same evening — tighter seals, quieter rooms and windows that open and close as they should.

Common problems we fix every week

Misted double glazing repair: replacing failed sealed units to restore clarity and insulation.
Window hinge/handle repair: swapping worn friction stays, resetting keeps and fitting new handles or locking gear.
Draughts and leaks: identifying gap paths, resealing perimeters, replacing weather gaskets and trickle-vent components.
Stuck or dropped sashes: re-aligning, toe-and-heeling and correcting packer positions to stop frames binding.
Sash window repair: renewing balances/cords, setting meeting rails and improving seals on sliding sashes.
Security upgrades: fitting modern cylinders, hinge guards and laminated glass in vulnerable locations.

If a repair won’t genuinely last, we’ll say so — and show you the numbers so the decision is clear.

uPVC window repair — what’s usually involved

uPVC is robust, but hardware and seals wear over time. A typical uPVC window repair might include:

Removing the sash to replace friction hinges and recalibrate opening tension.
Resetting striker keeps so multi-point locks engage smoothly without excessive handle force.
Swapping flattened gaskets and re-sealing the perimeter to cut draughts.
Re-glazing and toe-and-heeling larger sashes so they don’t drop.
Cleaning and re-lubricating moving parts for a light, consistent action.

Misted double glazing repair — clear views, better insulation

A foggy pane means the sealed unit has failed. We:

Measure the glass accurately (including spacer thickness and coatings).
Order a matching A-rated replacement unit (privacy/acoustic/solar options available).
Remove beading, extract the old unit and install the new with warm-edge spacers where specified.
Re-bead, seal and test for airtightness.

Results: clearer views, better thermal performance and far less condensation around the edges.

Hinge and handle issues — small parts, big difference

Worn friction stays cause dropped corners, rattles in the wind and sashes that scrape. Tired handles and out-of-line keeps force you to “lean” on the hardware to lock. We match hinge type and stack height, replace as pairs for symmetry, re-align keeps and set the handle gearbox so everything closes with a firm, light action. It feels new because, in the right places, it is.

Sash window repair — keeping heritage smooth and snug

For sliding sashes we offer:

New balances or cords and pulleys, correctly rated to the sash weight.
Meeting-rail alignment and latch setting for a positive close.
Brush and compression seals that cut whistling draughts without spoiling sightlines.
Optional acoustic laminates or safety glass in critical panes.

Where frames are sound, sash window repair preserves character and lifts comfort swiftly.

Repair vs replace — honest guidance on best value

We apply a simple rule: will this repair deliver a stable, multi-year fix?

Repair is best for isolated failures: a single misted unit, a couple of worn hinges, a handle or lock problem, or gaskets past their best.
Replacement is wiser when multiple panes have failed, frames are warped, sashes are heavily dropped or ventilation/compliance needs can’t be achieved with the existing frame.

If replacement makes more long-term sense, we’ll price both routes so you can decide with confidence.

Our repair process — quick, tidy, traceable

Diagnosis and options
We inspect the window, identify root causes (not just symptoms) and give you clear choices with itemised pricing.
Parts matched correctly
We source the exact hinge stack height, handle spindle length, gearbox type, gasket profile and sealed-unit spec to avoid “close enough” bodges.
Tidy on-site work
Dust sheets down, sashes removed safely, components swapped, frames realigned and seals dressed with clean, consistent beads.
Testing and sign-off
We check lock engagement, compression, reveal clearances and smooth operation — then talk you through care tips.
Aftercare
If anything beds-in and needs a tweak, we’ll return promptly.

Preventative maintenance — small habits, long life

A few minutes each season pays off:

Clean and check seals around the frame; replace any perished gaskets.
Lubricate hinges, keeps and handles lightly (avoid over-oiling).
Clear drainage channels at the bottom of frames to prevent water pooling.
Operate every opener a few times to keep hardware moving freely.
Inspect trickle vents and closers to ensure smooth airflow control.

Ask about an annual maintenance visit if you prefer a professional eye on things.

Noise, safety and privacy upgrades during repair

Repairs are the perfect moment to add practical enhancements:

Acoustic laminated units in front bedrooms or home offices to soften road noise.
Laminated security glass beside doors or at low level.
Privacy patterns for bathrooms and overlooked elevations.
Child-safety restrictors on upper floors for peace of mind.

We’ll explain costs and likely benefits so you can choose upgrades that you’ll genuinely notice.

Frequently asked questions about window repairs

How long does a typical uPVC window repair take?

Most hinge/handle jobs take under an hour per window; misted double glazing repair is usually a single visit to measure and a second to fit once the unit arrives.

Will repairing a misted unit fix condensation on the room side?

Replacing failed units stops moisture between panes. Room-side condensation relates to ventilation and room humidity — we’ll advise on vents and daily habits to help.

Can you repair old windows during winter?

Yes. We work cleanly and quickly, keeping rooms protected and warm. We’ll schedule glazed unit swaps to minimise time openings are uncovered.

Do repairs come with a guarantee?

Yes. New parts and sealed units come with manufacturer warranties, and our workmanship is guaranteed. We’ll outline terms clearly.

Are you able to repair windows from any installer?

In most cases, yes. We carry universal and brand-specific parts; if a system is obsolete, we’ll propose compatible solutions or replacement if that’s the only reliable route.

What influences the cost of window repairs?

Parts: hinges, gearboxes, handles, gaskets and sealed-unit sizes/specs.
Access: upper floors or bay windows may need extra time or equipment.
Extent: a simple hinge swap vs multiple windows with several issues.
Upgrades: acoustic/laminated glass or security hardware added during the repair.

Signs to call a repair specialist sooner rather than later

A corner of the sash catches the frame or the handle needs force to lock.
Draughts appear around the perimeter or you hear whistling in wind.
Moisture or fog forms between panes (not just on the room side).
Black-spot mould appears near the glass edge.
The window won’t stay open or slams shut unexpectedly.

Acting early prevents minor issues becoming costly damage.

Proactive care after your repair — five quick wins

Wipe frames with a mild solution; avoid abrasives that scuff gaskets.
Use a tiny dab of silicone-safe lubricant on hinges and keeps twice a year.
Keep curtains/blinds from pressing hard on trickle-vent paths.
Ventilate bathrooms/ kitchens after use to curb moisture.
Note any change in handle force — if it creeps up, call us before parts wear out.
