uPVC door won't lock, can it be fixed?

Almost always yes. The usual cause is a worn multipoint gearbox. Replacement units for Yale, Mila, Avocet, and ERA come on the van. Sunderland repairs typically £69 to £159.

What is a multipoint mechanism?

The metal strip running the height of the door with hooks, rollers, or shootbolts that engage into the frame when the handle lifts. The gearbox at handle height drives them and is the part that wears.

Door dropping or scraping the frame, fixable?

Usually yes. Hinges adjust up, down, in, and out. Postwar estate doors around Pennywell and Washington often need this every few years, especially after stormy winters off the coast.

How long does a uPVC repair take?

45 to 90 minutes for most jobs. Multipoint replacement is the longest part once the right gearbox is identified. Hinge alignment alone is often under 30 minutes.

Should I just replace the door?

Repair is far cheaper for a sound door. A new uPVC door is £600 plus and takes a fitter half a day. Replacing the failed mechanism is under £160 and 90 minutes.

Will my key still work after the repair?

Yes, as long as we replace only the multipoint. The cylinder and your key stay the same. If you also want an anti-snap cylinder upgrade, fresh keys come with that.

Are postwar estate doors near Washington worth fixing?

Generally yes. Frames and panels on those estates are usually structurally sound, the original mechanisms are what fail. A new gearbox extends the door's life by another decade for under £160.
