Expert Automatic Door Repair in Letchworth
Reliability is key for Letchworth's corporate and retail sectors. Our independent engineers specialize in zero-downtime door solutions. As independent specialists, we work on all major brands including Dorma, Record, Geze, and Assa Abloy.
Kevlar Drive Belt Tensioning
A loose belt causes 'juddering'. We install reinforced Kevlar timing belts and tension them to factory Newton-meter specs, ensuring smooth acceleration for your Letchworth entrance.
Battery Backup (UPS) Tests
In a power cut, your door must work. We test NiMH battery packs to ensure your door performs its emergency open/close function, a key fire safety requirement in Letchworth.
Threshold Track Cleaning
Grit in the floor guide destroys rollers. We deep clean the sub-floor track and replace stainless steel inserts to ensure gliding operation in Letchworth.
Glass Alignment & Anti-Rise
Heavy doors drop over time. We adjust eccentric rollers and anti-rise bolts to lift the door leaf, preventing it from scraping the floor in your Letchworth premises.
Digital Selector Switch Repair
Can't change modes? We replace faulty FPC 902 programmers, allowing Letchworth managers to toggle 'Auto', 'Exit Only', and 'Locked' easily.
