London branch

Everything we do from London

Every garage door service from the London branch, from repairs to new installations and maintenance.

Every service the London branch offers is below, for houses and for commercial buildings. Where a service has a page written for London, the link goes there.

This branch covers 79 places and almost none of them is a suburb of London. Sarnia is about 100 km west on the 402, Chatham further west again, Goderich and Clinton north to the lake, Stratford and St. Marys northeast, Woodstock east and St. Thomas south. Each is its own municipality with its own building department, which is why the town changes what can be promised about timing far more than the fault does. Nothing else reaches this market: Mississauga is 190 km away and Ottawa 600.

Snow is the reason so much of the work here is the bottom of the door. The London airport station records 190 cm of snowfall across November to April, 52 cm of it in January, against 114.5 cm for a whole year at Pearson. Wet snow packs against the panel, sits there and works into the seam. Past the city limits the same services are a different size of job: Middlesex County counts 2,352 farms across 246,592 hectares, and a machine shed door is a sectional overhead door built to whatever has to drive under it.
