A curtain hung diagonally means cast nylon or iron end-locks have sheared, or the bottom rail struck an obstruction while closing.
Van Fix: We secure the suspended curtain load, hydraulic-straighten bent U-channels, replace torn laths, and reset travel limits.
Complete loss of response stems from rainwater-corroded exterior key switches, blown control PCB fuses, or a triggered safety edge.
Van Fix: We carry weatherproof armoured key switches, single/3-phase control PCBs, safety edges, and rolling-code fobs for instant repair.
Buzzing or clicking with zero lift points to capacitor capacitance loss, a seized brake solenoid, or sheared reduction gearing.
Van Fix: We load-test phase voltage and install a replacement capacitor or complete tubular/industrial motor on the first visit.
Forklift impacts and crowbar attacks crease bottom T-bars, twist steel side guides, and jam bullet lock pins.
Van Fix: Same-night curtain rebuilds across Camden (NW1) using stocked 75mm galvanized laths and bullet locks—no timber boarding needed.
