Cracked uPVC Door Frame Lock Keep Rebuilt and Repaired

Right below the locking mechanism, the keep section of this white uPVC door frame had cracked clean through. The profile was split into a ragged hole with broken edges, and around it sat a cluster of redundant screw holes where fixings had been shifted over the years. Damage like this is more than cosmetic, since a broken keep stops the lock seating properly and leaves the door insecure. It is precisely the sort of uPVC door lock repair we are called to time and again.

People often search how to repair lock on upvc door and hope a tube of filler will do it, but rebuilding a load bearing keep so the lock engages cleanly is not a job for a generic uPVC door repair kit, which tends to leave a soft, mismatched patch that fails the next time the door is slammed. Our fully trained technicians rebuilt it properly, with proprietary materials and over 30 years of experience since 1993. The fractured section was reformed and reinforced, the old screw holes were filled, and the surface was made smooth and recoloured to match the original white profile before the keep was refitted so the lock bites correctly again.

The after image shows a solid, even frame with the keep sitting true and no trace of the earlier break, all completed on site in a single visit.
