Great communication. Paul was very thorough and dealt with our sticking patio doors. Although he came a little later than arranged we were kept fully informed and were able to track his journey. Very friendly. Pleased with the price of the work.

Third time using this company and as always, brilliant job. This time for replacement sealed units. Always my first call for glazing work.
Door locks fail more often than any other UPVC component, and across Portsmouth we get called out for them more than any other repair. The most common cause is the multi-point locking mechanism inside the door — the long metal mechanism that drives the bolts and hooks when you lift the handle and turn the key. When that fails, the door either won't lock at all, won't unlock, or feels heavy and grinds when you operate it. It's a security issue, an insurance issue, and increasingly a safety issue if you're locked out.
Restoration Glazing repairs and replaces UPVC and composite door locks across every Portsmouth postcode (PO1 to PO6). We carry the most common multi-point mechanism brands on the van — Yale, ERA, Maco, Roto, Fuhr, GU — and can often diagnose and fit in a single visit. Same-day appointments available for genuine lockouts and post-break-in security concerns.
We also fit upgraded TS007 3-star and SS312 Diamond anti-snap cylinders, which are increasingly required by UK home insurance policies — particularly relevant in higher-burglary postcodes across Portsmouth. From £45 per cylinder fitted.

Common Door Lock Issues We See in Portsmouth Properties
- •Multi-point mechanism failure in 15+ year-old UPVC across Cosham, Paulsgrove and Drayton — the gearbox inside the door wears, causing heavy operation, partial locking, or total lock-up
- •Snapped cylinders in Southsea ground-floor flats and Victorian conversions — older non-anti-snap cylinders broken during break-in attempts; these always need replacing, ideally with anti-snap upgrades
- •Misaligned strikers on dropped UPVC doors across older estates — when the door has dropped, the multi-point bolts no longer line up with their keeps
- •Composite door electronic lock failures in modern Gunwharf and Spinnaker apartments — newer composite doors with smart locks where the battery, motor, or controller has failed
- •Worn cylinders in Southsea student-let HMOs — multiple keys, high turnover, and rough handling wear the cylinder pins, eventually requiring replacement
Frequently Asked Questions — Door Lock Repair Portsmouth
How much does UPVC door lock repair cost in Portsmouth?
Multi-point mechanism replacement is typically £120-£220 fitted depending on brand and door height. Cylinder-only replacement (after losing keys or upgrading to anti-snap) is £45-£90 fitted. We diagnose first then quote — sometimes only the cylinder needs replacing.
My UPVC door won't lock — can you come today?
We offer same-day appointments where possible for active lockouts and security concerns. Call 023 8001 2328 to check today's availability. If we can't get there same day, we'll usually attend the next morning.
Should I upgrade to an anti-snap cylinder?
Yes — most UK home insurance policies now require TS007 3-star or SS312 Diamond rated cylinders, especially on UPVC and composite doors. If yours is older than 2015 it's almost certainly not anti-snap. Particularly important in higher-burglary Portsmouth postcodes.
Do you fit smart locks on Portsmouth apartments?
Yes — we fit and repair smart locks (Yale, ERA, Avia and similar) on composite doors common in Gunwharf, Spinnaker and modern apartment blocks. We can also retrofit smart cylinders to existing UPVC doors.
