Your uPVC Door Not Locking? We Fix It in One Visit
If your uPVC door won't lock when you lift the handle, the handle has dropped, or the multipoint mechanism is failing to catch, the cause is almost always a failed gearbox or worn locking strip — and both are fixable without touching the door itself. We carry Fullex, Winkhaus, Avocet, Yale and Mila gearboxes in the van, so in most cases we diagnose and complete the uPVC door repair in a single visit.
Our locksmith is Level 3 City & Guilds qualified, DBS-checked and fully insured. Every job comes with a fixed price before we start — no hidden extras, no call-out fee, and a 12-month guarantee on all parts and labour. Whether you're a homeowner in Clapham with a front door that won't secure, or a landlord in Croydon dealing with a tenant's failed mechanism, we give you an honest diagnosis and a clear price on arrival.
We cover all of South London — from Brixton and Balham to Peckham, Mitcham and Sutton. If a repair isn't possible, we'll tell you honestly. If you need a full lock change in South London afterwards, we handle that too. For lockouts, see our locked out South London page, or our broader lock repair South London service.

uPVC Door Repair Services
We fix all uPVC door faults — usually in a single visit, with parts from the van.
Gearbox Replacement
The central mechanism that drives every locking point on your door. When it fails, nothing catches. We match the exact gearbox to your door and replace it on-site.
Multipoint Lock Repair
Hook bolts, roller cams and deadbolts not fully engaging? We diagnose whether the strip or gearbox is at fault and replace only what's needed — saving unnecessary cost.
Handle & Spindle Repair
A dropped or floppy handle usually means the spindle connecting it to the gearbox has snapped. We replace the handle and spindle as a pair for a lasting repair.
Door Alignment & Hinge Adjustment
Hinge drop causes the door to sit low in the frame, putting strain on the lock and preventing full engagement. We realign flag hinges and adjust the keeps.
Anti-Snap Cylinder Upgrade
We replace standard euro cylinders with TS007 3-star anti-snap versions that are insurance approved and compatible with all uPVC doors across South London.
Patio & French Door Repair
Double-door systems use espagnolette strips, shootbolts and floor bolts. We carry parts for the most common brands and repair both leaves in a single visit.
Bifold Door Lock Repair
Bifold doors use a different locking method to standard uPVC. We diagnose and repair all bifold faults including alignment, mechanism failure and damaged rollers.
Broken Key Extraction
Key snapped inside the barrel? We extract it without drilling the lock, then assess whether the cylinder needs replacing — all handled in one visit.
How uPVC Door Repair Works
Simple, transparent process — fixed price before we start, most repairs done in one visit.
Call and Describe the Fault
Tell us what's happening: won't lock, handle dropped, door dragging. We ask a few quick questions so we arrive with the right parts ready, not empty-handed.
On-Site Diagnosis
We inspect the full door — gearbox, locking strip, hinges and cylinder. You get a fixed price before we touch anything. No surprises, no upselling.
Repaired in One Visit
We carry the most common uPVC multipoint parts for all major brands. Most repairs are completed within 60–90 minutes, leaving your door fully secure.
All uPVC Door Types Repaired
From standard front doors to bifolds and composites — we carry parts for all common types.
Standard uPVC Front & Back Doors
The most common uPVC door across South London homes. We stock gearboxes and strips for all standard sizes, configurations and brands.
French & Patio Doors
Double-leaf systems with espagnolette strips, shootbolts and floor bolts. We repair both leaves and ensure all locking points align correctly with the frame.
Bifold Doors
Multi-panel folding doors require careful alignment to lock correctly. We adjust, repair and replace locking mechanisms on all bifold brands without removing the door.
Composite Doors
Composite doors use the same multipoint mechanisms as uPVC. We repair all brands including Solidor, Rockdoor and Endurance — same parts, same visit.
Common uPVC Door Problems We Fix
Recognise your situation? We fix all of these — usually in a single visit.
Your Door Won't Lock at Night
You lift the handle but nothing catches. A failed gearbox is the most common cause. We can get to you same day and replace it on-site.
The Handle Has Dropped
The handle points down and feels loose. The spindle has likely snapped. A handle and spindle replacement restores full operation.
Door Won't Close Properly
The door drags on the carpet or sits too low to latch. Hinge drop is usually the cause. We realign the hinges so everything engages cleanly.
Hook Bolts Not Engaging
The key turns and the handle lifts, but one or more locking points don't catch. The gearbox or strip needs replacing.
Key Turns But Nothing Locks
The cylinder turns but the mechanism doesn't respond. Usually a failed internal gearbox component — repairable without replacing the door.
Stiff Handle, Hard to Lift
Worn gearbox springs or a misaligned door frame are the typical culprits. We diagnose the root cause and fix it.

Before You Call — 3 Things to Know
Help us help you faster by following these steps first.
Don't Force the Handle
Forcing a stiff or failed handle can snap the spindle or crack the gearbox housing, turning a £120 repair into a £350 one. If the handle won't lift smoothly, call us before applying pressure.
Don't Assume You Need a New Door
In almost every case, a uPVC door repair costs a fraction of replacement. The gearbox, strip and handles can all be changed independently. There is almost never a reason to replace the whole door.
Check the Hinges First
Look at your door from outside. If it's sitting lower than the frame or dragging on the threshold, hinge drop may be the cause rather than the lock itself. Let us know when you call — it means we arrive with the right tools.
