Composite Door Repairs — Sticking, Dropped & Locked Shut

The GRP skin expands as the sun warms it — dark colours worst of all — so a door that is slightly out of line jams by mid-afternoon and behaves again at night. A hinge and keep adjustment builds in room for that movement. It is the £85 flat visit, no parts.

Almost never. A slight thermal bow on a dark or south-facing door is normal and managed with keep and compression adjustment. A severe, permanent bow on a newer door is a manufacturer warranty matter — Max will tell you honestly which one you have before any money changes hands.

No — and be wary of anyone who offers. Planing cuts the GRP skin, exposes the core and voids the warranty. All alignment on a composite door happens at the hinges and keeps, which is exactly where Max works.

That is a dropped door: the hooks are missing their keeps until you take the slab’s weight yourself. Hinge realignment fixes it in one visit — and stops the strain that kills gearboxes.

Non-destructive entry comes first, and on most composite lockouts the door opens with no damage at all. Even in the rare case that drilling a seized part is the right call, it is done cleanly and the replacement means you won’t spot it once the job is finished.

Almost never. The locking hardware is the same multipoint family used on uPVC doors — if your exact gearbox pattern is discontinued, a gearbox-compatible case rebuilt on the old routing — “universal” repair locks are a last resort, less reliable in most cases, and Max says so before fitting one. A dead mechanism is a parts job, not a £1,500 door.

Labour is £85 + parts + VAT, quoted exactly before Max sets off — adjustment-only visits are £85 flat. Most composite repairs land between about £100 and £250 all-in; a new composite door runs £1,100–£2,500 fitted.

Yes. Brands differ in slab and core — Solidor and Endurance use solid timber, Door-Stop uses foam, Rockdoor adds aluminium reinforcement — but the locks, cylinders, handles and hinges are standard patterns carried in the van.

Dark skins absorb heat instead of reflecting it — surface temperatures reach 60–70°C in direct sun, so a graphite or black door moves far more than a white one on the same street. It is the single biggest factor in summer sticking.

Compression is uneven — the seal meets the frame on one side and not the other. Keep and hinge adjustment restores even pressure right round the slab; seals themselves are replaceable if perished.

Usually blocked drainage slots in the threshold or a failed bottom gasket. Worth sorting quickly on timber-core doors — persistent water at the core is the one thing that genuinely shortens a composite door’s life.

Yes — composite doors take the same euro-profile cylinders as uPVC. Every cylinder Max fits has snap protection as the baseline, with certified TS007 3★ and SS312 Diamond tiers when your door or insurer wants more.

Most jobs are one visit of 45–90 minutes. Gearboxes, cylinders, handles and hinges ride in the van, so diagnose-and-fix usually happens the same day you call.

Adjustment and hardware replacement count as maintenance and don’t touch the slab. What voids composite warranties is cutting or planing the skin — which is precisely what Max never does.

Snapped keys usually extract without replacing anything. If a worn, stiff cylinder caused the snap, it is replaced on the spot — anti-snap as standard — and the price is agreed before the work starts.

Usually, yes. With new composite doors at £1,100–£2,500 fitted, even a full multipoint strip plus new cylinder comes in at a fraction of replacement — and if a slab genuinely is beyond saving, Max will say so rather than sell you a repair.

Parts carry their manufacturer guarantees and the workmanship is Max’s own — every repair leaves with a 12-month workmanship warranty and maintenance guidance for the door, so it stays sorted. If something isn’t right after a repair, he comes back. That’s how a 600-review reputation stays at 5.0.

Specialist GRP paints exist, but many manufacturers void the skin warranty once a door is painted — and dark repaints raise skin temperature, which is exactly where bowing starts. If the goal is a fresh look, talk it through first; if the goal is a door that works, adjustment and hardware are the fix.

Yes. Policies usually ask for TS007 3-star or kitemarked cylinders on multipoint doors — fitted as standard tiers here. If your wording still says BS3621 (a mortice standard), Max fits the multipoint equivalent insurers accept and the invoice spells it out for your policy.

Creaks are usually dry hinges or the slab moving against a proud keep; banging is compression set too loose. Both are adjustment-and-lubrication fixes inside the £85 flat visit — and worth doing before the movement wears the gearbox.
