The Mississauga branch works out of an industrial unit, among the kind of buildings its commercial door work is for. From Unit 14, 1495 Bonhill Rd, in the Northeast Employment Area east of Dixie Road, it supplies, installs and repairs sectional overhead doors, rolling steel doors and rolling grilles across Mississauga and the GTA. How a sectional door and a rolling one differ, and why the spring is chosen by the traffic, is set out on the commercial doors page.
Environment Canada's 1991 to 2020 normals for Toronto Pearson count 22.3 days a year with winds of 52 km/h or more and 26.3 days with thunderstorms. The employment lands around the airport are flat and open, and a dock or bay door there takes the wind across a car park rather than behind a row of houses.
A 12-foot or 14-foot sectional door is a large panel, and wind pushes it into the opening until the rollers are pulled against the edge of the track. A door not built for that load bows, pops rollers, and jams on the next close; a door built for it has heavier struts on each section, heavier track and more brackets holding the track to the wall. Garage doors are tested for wind load to a published standard, ANSI/DASMA 108, so on an exposed opening ask for the door to be specified to a wind load and for the rating to be on the quote. A rolling door handles wind through its guides and windlocks on the ends of the slats, and the same question applies.
Many commercial calls are repairs to a door already in service: a section creased by a trailer, a rolling curtain that has dropped out of a guide, a cable or spring gone on a door that runs all day, a bottom bar pulled loose. The order is the same each time. Make the door safe, lock out the operator at its disconnect, and find out whether the door moves by hand. Then call (289) 975-9045, at any hour, with the door type, its size and what it is doing, and say when the dock can be without it. A door that cannot be closed on a full building is a night call; a door that is merely slow can wait for the quiet end of the shift.
Not every commercial door here is on a dock. Plazas and industrial units with a counter at the front close up with rolling grilles and rolling steel shutters, and those fail in their own ways: a slat that has jumped the guide after being forced, a bottom bar bent by a cart, a lock that no longer lines up because the curtain has dropped. A grille lets the shopfront be seen after hours and a solid shutter does not; which one suits a unit is a question for the owner and the insurer as much as for the door.
The branch also covers the wider GTA for commercial work. Overhead doors in St. Catharines has its own page, and garage door repair in Milton and garage door repair in Brampton are both served from Bonhill Road.
The opening width and height, the headroom and side room, sectional or rolling, insulated or not, the cycles a day, the exposure to wind, and whether the building is heated. The operator is chosen with the door rather than after it; commercial openers in Mississauga covers that half. A new or enlarged opening needs a City building permit before the door is ordered. Send the contact form or email info@protechgarage.ca with photos of the opening inside and out.
Everything we do in Mississauga · Commercial garage doors: what the job involves
The same range from every branch. What changes between them is who drives out, and on which number.
G-5000
The standard bay door: polyurethane injected between two steel skins, a grooved face, one and three quarter inches thick. Thinner and thicker builds exist at R-12 and R-18, and choosing between them is a question about whether the building is heated.
G-4400
An aluminium frame glazed across the whole face, for a showroom or a service bay the street should be able to see into. It is not insulated, and the glass is chosen per opening from more than twenty types, tempered or not.
Photographs are Garaga’s, the manufacturer whose doors we install. They show the models, not jobs we have completed. Colours shift on a screen, and headroom, backroom and the track decide which of these will physically fit an opening, so everything here is where a measurement starts.
Every one below has a page of its own, written the same way this one was.
Broken garage door springs? We replace torsion and extension springs safely and professionally to get your garage door working properly again.
Garage door sensor repair: the door starts down and reverses, or the opener light blinks. What the photo eyes are telling you, and when it is only alignment.
Garage door off track or not moving properly? Protech can safely realign the door, repair damaged tracks, replace rollers and get it running smoothly again.
Springs, cables, drums, rollers, hinges, brackets, seals and opener parts. What is on the truck, what is matched to the door, and what is not a DIY part.
A door that will not move, or stops halfway. The check order that tells you whether it is the opener, the springs, the track or ice, before anyone touches it.
Steel, aluminium and glass, wood and composite garage doors from Garaga, Amarr and Stanley. What the material, the layers and the insulation actually change.
Headroom, backroom and track type decide which doors will fit an opening. What an installation involves, and why the springs are sized to the new door.
Panel damage, rust at the bottom section, repeated failures and an uninsulated door on a heated garage. The four cases where replacing beats another repair.

Answered for Mississauga, on the number this branch answers.
The building decides. A heated warehouse or a unit with staff working near the dock loses heat through an uninsulated panel all winter, and an insulated sectional door also comes out stiffer against the wind. An unheated storage bay gains little from insulation, and a single-skin door there leaves more of the budget for the spring pack and the track.
Mostly the things a buyer cannot see in a brochure photo: the steel gauge, the struts, the wind rating, the spring pack sized to the cycle count, the track, and whether the operator is standard or continuous duty. Two quotes that differ a lot are usually specifying different doors, so compare those lines before the totals.
Call (289) 975-9045 at any hour, or email info@protechgarage.ca for a new-door quote with no rush.
