Services
Access control
We supply and install tailored access control systems for commercial properties, including mechanical and electrical solutions. Our systems allow customised access rights through keypads, key fobs, or swipe cards, enhancing security for schools, offices, and apartment blocks. With expertise in both stand-alone and networked systems, we ensure secure entry management while maintaining compliance with fire safety regulations.
Bars and grilles
Our made-to-measure security bars and retractable grilles protect residential and commercial properties against forced entry. Fixed bars suit low-visibility areas while collapsible grilles offer flexible security for shopfronts and patios. We install London and Birmingham bars for door reinforcement, meeting police recommendations. All installations comply with safety standards while maintaining aesthetic integration with existing architecture.
Domestic safes
We provide fire-resistant and security safes for home use, available in various sizes to protect valuables, documents, and electronics. Our installation service ensures compliance with manufacturer specifications and insurance requirements. We offer safe opening, rekeying, and additional key cutting services, with options for floor, wall, or underfloor mounting to suit different property types.
Locks
Our comprehensive lock services cover emergency lockouts, lock changes, and security upgrades. We supply and fit all lock types including anti-snap cylinders, digital locks, and multi-point locking systems. Registered key services prevent unauthorised duplication while our mobile key-cutting service ensures rapid response for urgent access needs across residential and commercial properties.
Glazing repairs
We offer 24/7 emergency boarding and glazing repairs for broken windows and doors. Our service includes replacing double-glazed units, UPVC window repairs, and installing toughened or laminated glass.
