Rated 5★ by Local Homeowners
"Torsion spring went with an almighty bang on a Sunday morning — car stuck inside, school run in chaos. Phoned at 8am, engineer was on the drive by 9.15 with the right spring on the van. Door balanced perfectly when he left and he showed me how to test it. £180 all in, no faff."
"Old Hörmann motor had been tripping the consumer unit for weeks. Quoted me a fixed price over the phone, swapped it for a Sommer unit the next morning, paired both remotes and tidied up the cabling. Whisper-quiet now — wife actually noticed."
"Garage door jammed halfway open at 9pm with the car half in, half out. Rang half-expecting voicemail — Steve picked up, talked me through dropping the manual release, and was round within 40 minutes to refit the cable that had jumped the drum. Charged a fair price for an out-of-hours call."
