Protech Garage Doors sells and installs garage door openers and new overhead doors across Hamilton, and repairs the ones already hanging there, from its branch at 1495 Bonhill Road in Mississauga, about 55 km by road down the QEW. The lower city's rear-lane garages, the Mountain's 1960s and 1970s streets and the bayfront's loading docks each want a different door and a different opener, and knowing which is which is most of the job. For a quote on an opener or a new door, or to book a repair, send the contact form or email info@protechgarage.ca.
Hamilton has three kinds of garage, and the escarpment sorts them
The 2021 Census counts 222,805 occupied dwellings in Hamilton, and 73,110 of them, one in three, were built in 1960 or before. Nearly all of those sit below the escarpment. The lower city was laid out on narrow lots, so where there is a garage it is usually at the back, on a rear lane: the City counted close to 100 kilometres of laneway in wards 1 to 4 when it rewrote the zoning to allow laneway houses in 2018. A detached garage on a lane off Barton Street is a single door, often the original wood one, on a slab that has heaved through seventy winters. It is unheated, and its opener, if it has one, was bolted on decades later to a ceiling never framed for it.
The Mountain is the second kind. Hamilton finished annexing Barton Township, the farmland on top of the escarpment, in 1960, and most of the 62,560 dwellings the Census dates to 1961 through 1980 are up there: bungalows and side-splits with an attached single, or a carport that somebody closed in later. Those doors are on their second or third opener. The door itself is often 1970s steel with nothing inside it, which is fine over a carport and a cold problem over a garage that shares a wall with the family room.
The third kind is the edge. Glanbrook, which is Binbrook and the airport lands, grew 95 per cent between 2006 and 2016 by the City's own count, and Waterdown on the far side of the escarpment reached about 24,400 people by 2021. Those are 2000s and 2010s two-car doors on the opener the builder hung: the calls for a quieter belt drive under a bedroom and for the first spring and cable change.
Openers and new doors
The opener is the part of a Hamilton garage that gets replaced most often, because it wears out on a schedule the house does not. Protech installs LiftMaster, Chamberlain and Genie openers: a belt drive for a Binbrook two-storey with a bedroom over the garage, a chain drive for a lane garage where nobody will hear it, and a wall-mounted unit where a lane garage has no ceiling room for a rail. New doors come from Garaga, Amarr and Stanley, and the Build Your Door designer will show a lane garage or a Mountain bungalow in the panel and colour before anyone orders steel. Insulated steel suits the attached garages of the Mountain; a plain single-layer door is the honest answer for a lane garage that is a shed with a car in it.
Overhead doors on the bayfront
The Port of Hamilton is 630 acres with 130 tenant companies and about 10 million tonnes of cargo a year. Stelco's Hamilton Works stopped making steel on 2013-12-31; the coke ovens and the cold-rolling lines still run, with about 750 people. Between the piers and Burlington Street the buildings are warehouses and transload sheds, and their doors are sectional overhead doors and dock doors that cycle from the first truck to the last. Protech services and replaces commercial doors and commercial openers there.
Repair, and what the drive means
Repairs are booked same day. The van comes from Bonhill Road over the QEW and the Burlington Skyway, then the 403 for the west end and downtown, the Lincoln Alexander Parkway for the Mountain, and the Red Hill Valley Parkway, open since 2007, for the east end. Downtown is about 55 km by road; Binbrook and Waterdown are further and in opposite directions, so give the street when you book and say whether the garage is attached or on a lane. No minutes are quoted here for the Skyway at five o'clock. A snapped spring, a door off its track and an opener that runs without moving the door are the usual three.
Permits in Hamilton
The City of Hamilton requires a building permit for a detached accessory structure larger than 15 square metres, and treats a garage or carport attached to the house as an addition that needs a permit at any size. Replacing a door in an existing opening is not on that list. Widening a lane garage opening is a different question, and so is the City's laneway-house zoning, which lets a garage on a lane in wards 1 to 4 become a dwelling of up to 550 square feet. Ask the City's building division for that address before ordering a door.
Repair or replace, in Hamilton's terms
What decides the bill is the door and the building it is on. A wood door on a lane garage whose slab has heaved is usually a replacement, because a new spring on a door that no longer meets the floor is money spent on a door that is leaving. A 1975 steel single on a Mountain bungalow that shares a wall with the house is a candidate for an insulated door, and the difference shows up in the room above it in February. A 2012 Binbrook double with a stripped opener gear is a repair, and a small one. Ask for the repair figure and the replacement figure together.

Answered for Hamilton specifically, not for everywhere at once.
My lane garage has no ceiling room for a rail. Is there an opener that fits?
A wall-mounted unit, which sits beside the torsion shaft instead of running a rail down the middle of the ceiling. That is the usual answer on a lane garage off Barton Street, where the building was never framed for an opener and whatever is up there was bolted on decades later. A chain drive is fine in a lane garage where nobody will hear it.
Is an insulated door worth it on the Mountain?
It depends what is behind the door. Most of the 62,560 dwellings dated 1961 to 1980 are up there, and their doors are often 1970s steel with nothing inside, which is fine over a carport and a cold problem over a garage sharing a wall with the family room. The difference shows up in the room above it in February. On a lane garage that is a shed with a car in it, a plain single-layer door does the job and the money is better spent elsewhere.
Does the laneway-house zoning affect my garage door?
It can, and it is worth raising before you order. The City zoning lets a garage on a lane in wards 1 to 4 become a dwelling of up to 550 square feet, which is a different building with different rules from the one the door is going on. Replacing a door in an existing opening is not on the permit list; widening a lane garage opening is a separate question for the building division.
