Services
Misted Window Repairs
We repair misted double-glazed units by replacing failed seals and glass panes. Our technicians diagnose moisture ingress causes, including blocked drainage or failed gaskets, and restore clarity while preserving original frames. This service extends window lifespan by 10+ years, avoiding costly replacements for properties in Sunderland and Durham.
UPVC Door Repairs
Faulty hinges, snapped locks, and dropped doors are addressed using manufacturer-specific parts. Our mobile vans carry common UPVC components for immediate fixes, including cylinder replacements and security tape installations. This prevents forced entry risks while maintaining door functionality for residential and commercial clients across the North East.
Emergency Boarding
Broken windows and doors receive temporary boarding within hours to prevent further damage. This service includes securing properties after break-ins or storm damage, using durable materials until permanent repairs are completed. Available 24/7 for urgent cases in Newcastle and surrounding areas.
Heritage Glass Repair
Specialist repairs for Georgian bar and leaded glass units maintain historical accuracy. We replace damaged wired cast glass in commercial buildings, ensuring safety compliance without altering aesthetic features. This service caters to conservation areas and listed properties requiring authentic restoration techniques.
Lock Replacements
Failed UPVC door locks are replaced at up to 80% less than master locksmith rates. We install high-security cylinders and restrictors to enhance home safety. Emergency lockouts are resolved swiftly, restoring access without frame damage for homeowners and businesses in Durham and Washington.
