North Toronto
Our technicians arrive in North Toronto ready for the everyday repairs: torsion and extension springs, lifting cables and drums, rollers, hinges, bottom seals, photo-eyes and opener gears. For bigger decisions, such as a new insulated door or a modern opener, we measure, advise and install as a separate service.

Every square is one home in a hundred.
Yes, mostly at floor level. Months of slush and road salt reach the lowest hinges, the bottom brackets and the loop of each cable before anything else on the door, so those get a close look for rust. The technician also checks whether the bottom seal has been freezing to the slab, how the drive has coped with cold, stiff starts, and whether frost or salt film has been blinding the sensors near the floor.
Once a year suits most attached garages here, ideally in the fall before cold weather thickens lubricant and stiffens seals. Door and opener makers suggest lubrication every three to six months and a homeowner balance check and reversal test every month, so an annual professional visit sits on top of that light routine. A lightly used door in a detached garage may go longer; a heavily used one, or one exposed to salt spray, benefits from a spring check too.
Lifting a crooked door is where most injuries around this problem happen, because the springs and cables are loaded unevenly and the door can shift suddenly. Tell the technician on the phone that a vehicle is inside; getting it out is part of the plan, and the door will be supported and levelled before it is raised. A short wait is far cheaper than a bent section or a hand caught between panels.
A photograph of the whole door from outside, a close-up of the damaged section, a picture of the manufacturer's label if you can find it, and a shot of the inside of the door showing the hinges, tracks and springs. Add the door's approximate width and height, whether it is insulated, its colour and panel style, and how the damage happened. That set often lets the technician confirm availability before arriving.
