My uPVC door won't lock, can you fix it?

Almost always yes. Most common cause is a worn multipoint mechanism inside the door, sometimes called a gearbox. We replace these without taking the door off. Repairs across NW postcodes usually run £69 to £159.

What is a multipoint lock and why does it fail?

It's the long mechanism running the height of your door with hooks, rollers, or shootbolts engaging into the frame when you lift the handle. The gearbox wears out, usually after 8 to 15 years of daily use.

Door is dropping or scraping the frame, can you fix it?

Yes. uPVC doors drop because hinges have worn or the panel has shifted. Re-aligning hinges and adjusting keeps usually solves it within an hour. A warped panel is a separate job.

How long does a typical NW postcode uPVC repair take?

Most jobs are done in 45 to 90 minutes. Multipoint replacement takes the longest, around 60 minutes. Yale, Mila, and Avocet gearboxes are stocked on the van.

Do I need a whole new door or can it be repaired?

Repair is almost always cheaper and faster. Full uPVC door swap is £600 plus and takes a fitter half a day. Replacing the failed mechanism is under £160 and 90 minutes.

Will the same key still work after repair?

Yes, if we are replacing only the mechanism, not the cylinder. The cylinder where the key goes stays unchanged. If the cylinder also needs an anti-snap upgrade, you'll get new keys.

We're in a 1990s estate near Wembley with original doors, worth fixing?

Often yes. 1990s and early-2000s uPVC doors in NW9 and NW10 are usually structurally sound but the gearboxes have worn out. Mechanism replacement extends life by another decade for under £160.

What Our Customers Say

Conservatory door multipoint had been catching for months. Finally died altogether. Heavy-duty replacement now in place, closes solidly for the first time in ages.

Richard B. uPVC door repair
Victorian terrace in NW10, the heavy front door handle snapped off in my hand. Right replacement on the van. Fitted in twenty-five minutes flat.

Tom W. uPVC door repair
Replaced every lock in the flat after a difficult split. Five locks across an Edwardian conversion, done in just over two hours. No questions, no awkwardness.

Naomi F. Lock change
New rental in Kilburn, previous tenant said they'd lost a key. Got both externals changed within two hours of the booking. The phone quote matched the receipt.
