My uPVC door won't lock when it gets cold. What's wrong?

Almost always door drop or a worn multipoint gearbox. The mechanism stops aligning with the keep, the hooks won't engage, and damp Cornish weather makes it worse. Realignment plus a gearbox swap fixes most cases.

How much does a uPVC repair cost in the TR area?

£69 to £159 depending on the cause. Hinge adjustment and keep alignment is the cheap end, a full multipoint gearbox replacement is the upper end.

Can you replace just the gearbox or do I need a whole new mechanism?

Usually just the gearbox. The full multipoint strip costs more and only makes sense if the hooks or the strip itself are damaged. We carry the common gearbox patterns.

My handle came off in my hand. Can you fix it?

Yes. Inline and offset uPVC handles are stocked on the van. Most replacements are 15 to 20 minutes once we identify the spindle size and pattern.

Will I need to replace the whole door?

Very rarely. Almost every uPVC door problem is the mechanism, the hinges or the keep. The slab itself is fine. Replacing the door is a last resort.

Do you handle composite doors as well?

Yes. Composites use the same multipoint locking systems as uPVC, just with a thicker slab. Same parts, same engineers.

How long until you can get someone out for a uPVC repair?

Same day for emergencies in Truro and the surrounding TR postcodes. Booked appointments usually within 24 to 48 hours.
