uPVC Alignment & Multipoint
uPVC Double Glazing & Patio Repair Specialists
Sagged door refuses to lock? Lock handle spin with no response? Expert uPVC multipoint locks, gearbox replacement, sash jam adjustments.
Specialist uPVC Door and Window Locks
uPVC composite, French doors, and patio systems use a complex multipoint locking mechanism containing roller cams, hooks, deadbolts, and central gearboxes. Over time, heavy double glazed panes can pull doors out of alignment, making the mechanism load-bearing and preventing safe lock-up.
Our specialized uPVC repair technicians carry an extensive range of replacement gearboxes, central lock strips, sash jammers, and composite euro cylinders to fix and align faulty uPVC mechanisms in one single visit.
Typical uPVC Failure Indicators:
•Lock handle becomes incredibly stiff to lift or push before locking.
•The key will only rotate partially when trying to lock or unlock.
•The door handle spins completely loose without engaging internal locking cams.
