Why won't my uPVC door lock anymore?

Usually a worn-out multipoint gearbox or a door that's dropped on its hinges so the lock points miss the keeps. Both common, both quick.

How much does a uPVC repair cost in SW London?

Realignment with no parts £69. Multipoint replacement £109 to £149. Handle pair £69. Cylinder swap £89 to £119.

Does the brand of the door matter?

Yes for parts. Most SW conversions have Yale, Mila, Avocet or Fuhr hardware. We carry the major gearbox patterns in the van so jobs finish in one visit.

Multipoint replacement 45 to 75 minutes. Realignment around 20 minutes.

Cheaper to replace the door entirely?

Almost never. Composite door replacement starts around £900. Repair lands under £160. Replace only when the slab is cracked or warped.

Will my keys still work after?

Yes when only the gearbox is replaced. Three new keys come with any cylinder swap.

Patio doors and French doors handled too?

Yes. Patio gearboxes, French door multipoints with shoot bolts, conservatory doors. All standard work for SW postcodes.
