Door Won't Lock?
A UPVC door that has become difficult to lock doesn't necessarily need replacing. The problem may be caused by alignment, hinges, the gearbox or another part of the multipoint locking mechanism.
UPVC Repairs Doctor can diagnose the fault and recommend the appropriate repair.

Send PhotosFrequently Asked Questions
Can a UPVC door that won't lock be repaired?
In many cases, yes. Problems can be caused by alignment, hinges, the lock, gearbox or multipoint mechanism. The fault needs diagnosing before the correct repair can be recommended.
Do I need a complete new door if the gearbox fails?
Not necessarily. Failed locking components can often be replaced while keeping the existing door where suitable parts and the condition of the door allow.
Can misted double glazing be replaced without changing the frame?
Often, yes. A failed sealed glass unit can usually be replaced while retaining a suitable existing UPVC frame.
Can I send photos before arranging a visit?
Yes. Send photos or a short video on WhatsApp along with your postcode and a description of the problem.
