uPVC door repairs

Most uPVC door faults come down to a worn mechanism, a dropped frame, or alignment that has shifted over time — not a failed door. We diagnose first and repair where possible, saving you the cost of a new door.

• Door won’t lock or handle won’t lift — usually a failed multipoint mechanism or alignment issue.
• Multipoint locking mechanism replacement — we source and fit the correct gearbox for your door.
• Stiff, dropped or misaligned doors — adjustment and realignment to restore a smooth close and proper lock engagement.
• uPVC door handles — broken, loose or snapped handles replaced like-for-like or upgraded.
• Cylinder replacement — including anti-snap TS007 3-star upgrades for better security.
• Cat flap and letterbox fitting — cut and fitted to existing uPVC doors.

uPVC window handles & window locks

Window hardware fails for the same reasons as doors: wear, alignment shift, or cheap original parts. We supply and fit replacement uPVC window handles and window locks across all the common profile types found in Finsbury Park properties.

• uPVC window handles — broken, loose or stiff espag handles replaced. We carry a range of standard colours and finishes (white, gold, chrome, black).
• Window lock mechanisms (espagnolette) — the internal locking bar that the handle drives. When the mechanism fails, the window won’t lock even with a working handle.
• Window restrictors — fitted to limit how far a window opens — useful for child safety, ground-floor security, and some insurance or HMO requirements.
• Window locks (keyed) — additional key-operated locks fitted to casement, tilt-and-turn and sash windows for improved security and insurance compliance.
• Sash window locks — surface-mounted and mortice-type sash locks for timber sash windows common in older Finsbury Park properties.
• Tilt-and-turn window mechanism repair — windows stuck in tilt mode or that won’t switch between functions.

Repair where possible, replace when needed

We always diagnose the actual problem before recommending parts. Many faults that look expensive — a door that won’t close, a window that won’t lock — come down to a single worn component. If a part genuinely needs replacing, we’ll show you why and confirm the cost before proceeding.

Frequently asked questions

My uPVC door only locks when I lift the handle hard. Is that a problem?

Yes — that’s a classic sign of alignment trouble or a mechanism starting to wear. It’s worth fixing early before the mechanism fails completely and leaves you locked out or unable to secure the door.

My window handle turns but the window doesn’t lock. What’s wrong?

The espagnolette mechanism inside the frame has likely failed — the handle is working but the locking bar isn’t moving. We can replace just the mechanism without touching the glass or the frame.

Do I need a specific handle for my window profile?

Sometimes, yes — uPVC handles vary by spindle size, backplate dimensions and locking direction. Send us a photo on WhatsApp and we’ll identify the right replacement before attending.

Do window locks help with my home insurance?

Many policies require key-operated locks on accessible ground-floor and low-level windows. Check your policy wording — we can fit key-operated window locks and supply a receipt of work if needed.

Do I need a whole new door or window?

Rarely. In most cases the frame is fine and only the handle, mechanism or cylinder needs replacing. We’ll always tell you honestly if a full replacement is actually necessary.
