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 NN postcodes typically 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 is the part that wears out, usually after 8 to 15 years of daily use.

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

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 Northampton uPVC repair take?

Most jobs done in 45 to 90 minutes. Multipoint replacement takes the longest, around 60 minutes. Yale, Mila, and Avocet gearboxes 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 half a day. Replacing the failed mechanism is under £160 and 90 minutes.

Will the same key still work after repair?

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

We're in a 1960s estate near Kingsthorpe with original doors, worth fixing?

Often yes. 1990s and early-2000s uPVC doors across NN2 and NN5 are usually structurally sound but the gearboxes have worn out. Mechanism replacement extends life by another decade for under £160.

What Our Customers Say

Composite front door in Abington started catching badly on the frame. Hinges needed adjusting and the gearbox was on its way out. Sorted in just over an hour.

David K. uPVC door repair
uPVC back door wouldn't lift to lock. Worn keep, hinges dropping. Diagnosed and fixed in one visit, no follow-up needed.

Charlotte N. uPVC door repair
Said no callout fee. Meant it. 1am call, came out to a flat near the town centre, charged £55 flat for the lockout. No upsell.

Andrew C. Emergency lockout
Key snapped clean in the front door before work. Engineer extracted both halves within ten minutes of arriving. Cut a new one on the spot.
