uPVC door not locking? Handle stiff or dropped? Door not closing properly? In the vast majority of cases it's the locking mechanism, handle, hinge, or cylinder at fault — not the door frame. We repair on the same visit, saving you the cost of a new door.
Common Faults
Most uPVC door problems are caused by worn or faulty components — not the frame itself. We replace the part, not the whole door.
The most common uPVC door fault. The gearbox or locking strip wears out — the handle lifts but the door won't lock, or the handle feels very stiff. We replace the mechanism on the same visit.
Old euro cylinders on uPVC doors are a main target for forced entry via lock snapping. We upgrade to TS007 3-star anti-snap cylinders — insurance approved and fitted in under an hour.
Broken, floppy, or seized handles are the second most common uPVC door fault. We carry a wide range of standard handle styles and sizes on the van for same-day fitting.
Dropped or misaligned uPVC doors are almost always caused by worn flag or butt hinges. We replace hinges to bring the door back into alignment and ensure it seals and locks properly.
Shoot bolts (top and bottom locking points) and door keeps repaired or replaced when the door won't lock at all points, or when locking feels stiff on a specific point.
Perished rubber seals on uPVC door frames replaced to restore draught-proofing and weatherproofing. Prevents heat loss and water ingress around the door.
Why BLD
uPVC doors are low maintenance, but their multi-point locking mechanisms, gearboxes, and handles do wear out over time. When a uPVC door will not lock, will not open, or is draughty, BLD carry out same-day repairs across London — often fixing the mechanism without replacing the whole door.

FAQ
The most common cause is a worn or faulty gearbox or multipoint locking mechanism. The lock will feel loose, or the handle will drop. We carry the most common gearbox sizes and can usually replace on the same visit.
Yes. In most cases we replace only the gearbox component, keeping the existing keep, cylinder, and handles where they are serviceable. This is far cheaper than replacing the whole door lock.
A TS007 rated cylinder is designed to break at a sacrificial point before the lock mechanism is compromised in a snap attack. We fit anti-snap cylinders as standard when replacing uPVC door cylinders.
No — there is never a call-out fee. We confirm the price for the work before we start. You only pay for what we do.
