Services
UPVC Lock Repair UPVC Lock Repair
We offer affordable repairs for uPVC door locks using high-quality replacement parts and upgraded locking systems. Many faulty or obsolete mechanisms can be repaired or retrofitted instead of replacing the whole door. When locks become difficult to use, we identify the underlying alignment issue and resolve it before further failure develops. Every repair is completed with attention to security, function, and durability.
Lock Upgrades
Lock Upgrades
Our lock upgrade service is designed to improve the security of properties fitted with outdated locking systems. As criminal techniques develop, older locks can become increasingly vulnerable and may fail to meet current insurance standards. We fit a wide selection of BS3621 and SS312 compliant products to help maintain valid cover. We can also inspect your existing locks and recommend suitable improvements where required.
Anti Snap Locks
Anti Snap Locks
We install advanced anti snap locks to improve security against the increasingly common method of lock snapping. Our 3 star SS312 diamond standard cylinders are built to withstand recognised euro cylinder attacks and comply with industry testing standards. To provide further protection, we also fit high-security door handles and sash jammers. Every installation is completed using carefully selected, high-quality security products.
Lock Opening Lock Opening

Steven was at my house in under an hour after I first messaged him to say my front door lock had jammed. He was clear up front on his pricing, and talked me through what options were available to me, and was also able to change the locks on another door while he was there. He also gave me some good followup security advice which was very appreciated.

Patio door was shut and wouldnt open, Steve quickly got around that problem. The mechanism was broken beyond repair, he quickly sourced a replacement and fitted it. Called him Friday, he attended on Monday, job was completed with replacement parts and upgraded locks by Thursday of the same week.

Steve rescued us on a cold January evening when we were locked out. On top of getting us back in the house, he also improved the door mechanism whilst fitting the new lock. Amazing service and excellent value!
