When the London branch hangs a first opener on a garage, or a new one where the old unit is finished, 3 checks come before the day: power at the ceiling, anyone else who must agree, and the headroom over the opening. How a unit is sized and hung is on the opener installation page. The branch number is (226) 270-9715.
Power at the ceiling, under Ontario rules
An opener needs an outlet beside the motor head, and where the ceiling has none, or a detached garage has no circuit out to it, the outlet is the first job. In Ontario that wiring belongs to a contractor holding a 7-digit ECRA/ESA licence, the only kind of business the Electrical Safety Authority lets do electrical work in a home, or to owners in their own house who file with the ESA before starting. Ask to see the number.
When the work passes inspection, the ESA issues a Certificate of Acceptance, which it calls important for insurance and resale; file it with the house papers. The outlet goes in first and the opener after.
Condominium townhouses: the board before the bracket
At the 2021 census, 28,475 occupied London dwellings were in condominium, apartments among them. A declaration fixes where each unit stops, and so whether a garage door is the owner's or a common element; a part one owner uses alone, the balcony being the usual example, can still be an exclusive-use common element owned by the corporation. The Condominium Authority of Ontario says most changes an owner proposes to common elements need board approval and a formal agreement under section 98 of the Condominium Act. An opener bolts to the ceiling and pulls on the top section, which on a light door takes a strut. Put it to the board before anything is ordered; an owner can get the declaration from the corporation with a records request.
Headroom above the opening
Garaga, one of 3 door makers the branch installs, publishes the figures: 12 inches, 305 mm, above the opening for standard lift on torsion springs, 8 1/2 inches on extension springs, and 2 inches more either way once an electric opener goes on. On London's pre-war streets, where a garage came after a lot laid out before the car, that headroom runs short, so the tape goes there first. In Stratford, about 60 km northeast, such garages can hide a collar tie or a light fixture where the rail wants to run. Where the rail cannot go and the door hangs on a torsion spring, ask about a wall-mount unit beside it, which also needs side room.
Out of town
Up Highway 4, Exeter is about 45 km north, and the 110 homes it gained from 2016 to 2021 usually carry the builder's opener. Out past Dorchester, about 16 km east-southeast, the call is often a machine shed whose door is wider and taller than standard, and the unit is picked for that weight. Say which town.
Booking
Send the contact form with the door's width and height, the height from the top of the opening to the ceiling and to the lowest thing hanging below it, and a photo showing any outlet up there. Condominium owners add what the board said. A door that will not stay put at waist height with the opener off is a spring job first.

Answered for London, on the number this branch answers.
There is no outlet on the garage ceiling. Who puts one in?
A contractor holding a 7-digit ECRA/ESA licence, since the Electrical Safety Authority lets no other kind of business do electrical work in a home, or the owner of the house, who files with the ESA before starting. Ask to see the number. Once the work passes inspection the ESA issues a Certificate of Acceptance, and the opener goes in after that.
Does an opener in a condominium townhouse need approval?
Often, so ask the corporation first. The declaration fixes where each unit stops and so whether the door is the owner's, and the Condominium Authority of Ontario says most changes an owner proposes to common elements need board approval and a section 98 agreement. An opener bolts to the ceiling and pulls on the top section of the door. A records request gets you a copy of the declaration.
How much headroom does an opener need above the door?
On Garaga's figures, 12 inches, 305 mm, above the opening for standard lift on torsion springs, or 8 1/2 inches on extension springs, then 2 inches more once an electric opener goes on. Measure from the top of the opening to the ceiling and to anything hanging lower. Short of that, on a torsion-spring door, a wall-mount unit beside the door is the one to ask about.
