Composite door not locking properly? Handle feels stiff or floppy? Most composite door problems are with the locking mechanism, handle, or cylinder — components we carry on the van and replace on the same visit.
What We Fix
Multi-point mechanisms, anti-snap cylinders, handles, hinges and hardware — we carry the parts for the most common composite door faults and fix them on the same visit.
The most common composite door fault. The gearbox or locking strip wears out, leaving the door stiff or unable to lock. We replace the mechanism on the same visit.
Old cylinders on composite doors are a key weak point for forced entry. We upgrade to TS007 3-star anti-snap, anti-drill cylinders — insurance-approved and fitted same day.
Composite door handles (lever-lever and lever-pad styles) replaced when broken, stiff, or loose. We carry a wide range of handle configurations in the van.
Dropped or misaligned composite doors are usually caused by worn hinges. We replace and re-hang composite door hinges to restore correct alignment and weatherseal.
Letterplates, knockers, and door knockers replaced. Letterbox draught excluders fitted to stop heat loss through the door front.
Shoot bolts (top and bottom locking points) repaired or replaced. Keeps adjusted or replaced when the door won't lock smoothly at all points.

FAQ
The most common cause is a worn or failed multipoint gearbox — the component that drives the locking points when you lift the handle. A worn gearbox often feels stiff or causes the handle to drop. We replace the mechanism on the same visit.
Lock snapping is a common burglary technique. TS007 3-star anti-snap cylinders break at a sacrificial point before the mechanism is compromised. If your cylinder is more than a few years old, upgrading is strongly recommended — and we can fit one same day.
In most cases yes. We carry a range of lever-lever and lever-pad handle sets in various finishes. If we don’t have an exact match on the van, we can source and return to fit — usually within a day or two.
No — there is never a call-out fee. We confirm the price for the repair before we start, and you only pay for the work carried out.
