Why won't my uPVC door lock unless I lift the handle hard?

Usually the door has dropped on its hinges or the keeps are out of alignment. Sea air on Cardiff Bay properties accelerates this. A quick adjustment often fixes it without any new parts.

What does uPVC repair cost?

Realignments and hinge adjustments start at £69. Full multipoint gearbox replacements run £119 to £159. A new handle set on top is typically £25 to £45.

Can you repair the door same day?

Most multipoint gearboxes (Yale, Avocet, Fuhr, GU, Maco) are stocked on the van. Common patio and bi-fold parts are also carried, so same-day completion is the norm.

My composite door won't shut at all, is it the lock?

Could be the gearbox, the keeps, the hinges or a swollen frame after wet weather. Engineers diagnose on site within 10 minutes and quote before any work starts.

Do you replace just the cylinder or the whole mechanism?

Whichever the fault calls for. A snapped cylinder needs only a new euro cylinder. A failed multipoint needs the gearbox replaced. We don't upsell the bigger job if the smaller one fixes it.

Is uPVC repair cheaper than fitting a new door?

Almost always. A full new composite door runs £900 to £1,800 fitted. Repairs sit under £200 for the vast majority of faults we see across CF postcodes.

Will the repair affect my warranty?

If your door is under the original installer warranty, repair work by us won't void it provided like-for-like parts are used. We document everything in case the manufacturer asks.

What Our Customers Say

Composite door on a Caerphilly new build wouldn't latch properly. Adjusted the keeps and replaced the centre case. £99 and a bit of advice on keeping the seals clean.

Gareth E. uPVC door repair
Mechanism on our front door in Whitchurch had been getting stiff for weeks. Turns out the multipoint was on its last legs. New gearbox fitted same afternoon, £149. He even oiled the hinges before leaving.

Megan F. uPVC door repair
Front door cylinder snapped during an attempted break-in on our Cathays terrace. Police left, locksmith arrived 22 minutes later and fitted a 3-star anti-snap. Felt safe enough to sleep that night.

Ben H. Burglary repair
Locked out of my Roath terrace at half past midnight after the front door slammed shut behind me. The engineer rolled up in 19 minutes, picked the lock without a scratch on the paint, and charged £59 flat.
