Services
uPVC door repairs
We specialise in uPVC door repairs, addressing failed multipoint locks and misalignment issues without requiring full door replacement. Using genuine parts and a two-year guarantee, our engineers restore functionality and security. Services include handle replacements, lock barrel upgrades, and emergency access solutions, ensuring cost-effective, durable results for homeowners and businesses.
Anti-snap locks
Our anti-snap lock installations protect against burglary by preventing lock snapping attacks. We fit high-security Ultion WXM cylinders with anti-pick, anti-drill, and anti-bump features. Combined with PAS 24 handles, these locks create robust barriers against forced entry, offering long-term peace of mind for residential and commercial properties.
Composite door repairs
We repair composite doors with multipoint lock failures, misalignment, or broken handles. Our technicians use genuine Hoppe and FabFix components to replace gearboxes, adjust hinges, and seal drafts. This preserves your existing door's integrity while enhancing security and energy efficiency through precise, same-day repairs.
Patio door repairs
Our patio door repairs address gearbox failures, misalignment, and broken handles without necessitating full replacements. We service tilt-and-slide, bi-fold, and traditional sliding mechanisms, restoring smooth operation and security. Services include hinge adjustments, seal replacements, and draught-proofing to extend your door's lifespan cost-effectively.
Commercial locksmith
We provide tailored commercial security solutions, including coded lock installations, master key systems, and roller shutter lock replacements. Our DBS-checked engineers serve schools, retail spaces, and council properties, offering emergency access, lock audits, and insurance-compliant upgrades to protect business assets and ensure operational continuity.
