Can misty double glazing be repaired without replacing the whole window?

Yes. Misted or fogged-up double glazing means the sealed glass unit has failed — but the frame is usually fine. We replace just the glass unit, not the whole window, which costs a fraction of full window replacement and usually takes under an hour per unit once the new glass arrives.

My uPVC door won't lock or is hard to close — can it be fixed?

Almost always. Doors that won't lock, need lifting to close, or catch on the frame usually just need realignment of the hinges and keeps, or a replacement gearbox in the multi-point lock. Both are routine repairs that are far cheaper than a new door.

Is it worth repairing an old door, or should I replace it?

If the door slab and frame are sound, a repair is usually the right call and we'll tell you so. If the door is warped, rotten or has failed in several places, repair money is often better put toward a new composite or uPVC door — we do both, so you'll get an honest recommendation either way.

What we fix

The repairs we're called out for most

Misty / fogged double glazing

Condensation trapped between the panes means the sealed unit has failed — not the window. We replace just the glass unit, at a fraction of the cost of a new window, usually in under an hour per unit.

Locks & gearboxes

Key won't turn, door won't lock, or the handle lifts but nothing engages? Multi-point lock gearboxes fail with age — a routine replacement that restores full security the same visit. Anti-snap cylinder upgrades available too.

Dropped & catching doors

If you're lifting, shouldering or slamming your door to close it, the hinges and keeps need realignment. A quick adjustment now prevents a wrecked gearbox later.

Handles & hinges

Snapped handles, seized hinges, stiff mechanisms — replaced with matching or upgraded parts on uPVC and composite doors and windows.

Draughts & seals

Perished gaskets and flattened weather seals let the heat out and the Belfast weather in. New seals make an old door or window feel years younger.

Window mechanisms

Broken friction stays, windows that won't open (or won't stay shut), and failed espag locks on uPVC windows — all standard fixes.

Straight answers

Repair it or replace it? We'll tell you honestly

Because we fit new doors and windows as well as repairing them, we've no reason to push you either way — the honest answer is the one that keeps your business and your recommendation.

✅ Repair usually wins when…

The frame and door slab are sound
It's one failed part — a unit, lock, handle or hinge
The door or window is under ~15 years old
You're happy with how it looks

🔄 Replacement makes sense when…

The door is warped, cracked or rotten
Several parts have failed or keep failing
Single glazing or first-generation uPVC is costing you heat
Security is the worry — see our composite doors from £1,750 fitted

Not sure which side you're on? Send us a photo — we'll tell you straight, and if a £90 repair does the job, that's what we'll recommend.

Repair questions

Repairs FAQ

Can misty double glazing be fixed without a whole new window?

Yes. Misting between the panes means the sealed glass unit has failed — the frame is usually fine. We replace just the unit, which costs a fraction of a full window and usually takes under an hour once the new glass arrives.

My door won't lock / needs lifted to close — fixable?

Almost always. It usually needs hinge and keep realignment, or a new gearbox in the multi-point lock. Both are routine and far cheaper than a new door — and fixing it early stops a small fault becoming a big one.

Do you charge a call-out fee?

No — quotes are free, and for most repairs we can price the job from a photo and description over the phone. The price is agreed before any work starts.

Should I repair my old door or replace it?

If the slab and frame are sound, repair is usually right — and we'll say so. If it's warped, rotten or failing repeatedly, the repair money is often better put toward a new composite or uPVC door. We do both, so the advice is honest either way.

Which areas do you cover?
