Doors and openers we install and service
Protech Garage Doors repairs, replaces and installs garage doors and openers across Ottawa from its shop at 46 Grenfell Crescent in Nepean. The phone line is open 24 hours. Call (613) 845-9950 for a snapped spring, a door that has come off its track, an opener that will not respond, or a quote on a new door.
Whether your garage door needs a quick repair, a replacement or help with noise, Protech is here to help.
A spring has gone, a cable has slipped its drum, or the safety sensors are out of line. Same-day, and the truck carries the parts.
What we fixDented, drafty, or thirty years old. Steel, insulated, wood and composite, measured on your opening before anything is quoted.
See the doorsA motor that runs while the door stays put is usually a stripped gear kit, which is a repair. One that stalls after a tune-up is not.
Openers we serviceMost repair calls are a spring, a cable, a track, a sensor or an opener. A torsion spring snaps with a bang and the door turns too heavy to lift. A cable slips off its drum and the door hangs crooked on one side. Rollers jump the track. The photo-eye sensors at the bottom of the tracks get knocked out of line, so the door reverses instead of closing. Or the opener hums and nothing moves.
The truck carries torsion and extension springs, cables, rollers, hinges, drums and opener gear kits, and repairs are booked same day.
A spring is not a homeowner job. A torsion spring on a double door is under enough tension to injure, and the spring pairing, the drum setting and the cable length all have to match the weight of that particular door.
Cold changes how a door behaves. Steel springs stiffen as the temperature falls, old grease thickens, and a door that glided in September drags in January. The opener works harder against it, and a spring that was already worn is likelier to let go on a cold morning. Two things help: a lubrication and tune-up before the snow, and keeping the bottom seal clear of packed snow and ice so the door is not frozen to the slab on the morning you need to leave.
We repair and replace LiftMaster, Chamberlain and Genie openers: chain drive, belt drive and screw drive. When the motor runs but the door does not move, the fault is usually a stripped gear kit, which is a repair rather than a new unit. An opener that stalls, runs loud, or stops partway even after a tune-up has reached the end of its life and gets replaced. A heavy steel, wooden or carriage-style door gets a 3/4 horsepower opener; a lighter door does fine on 1/2.
For a replacement we supply and install residential and commercial doors from Garaga, Amarr and Stanley. Steel is the usual choice: a single-layer door where the garage is unheated and lightly used, and a double-layer insulated door where the garage shares a wall with the house. The insulation is either polystyrene, the lighter option, or polyurethane foam, the heavier one. Ask for rubber weather stripping on the top, bottom and sides rather than PVC, which cracks as it ages. Wood and composite doors suit a house whose front calls for them.
The Nepean shop covers the whole city, Kanata, Barrhaven, Orléans, Nepean, Stittsville, Manotick and Gloucester, and the towns around Ottawa: Arnprior and Carleton Place to the west, Rockland to the east, Kemptville to the south. The full list is on the areas page linked below.
Call (613) 845-9950 at any hour. Have the door type and what you can see or hear ready. A bang from the garage followed by a door that will not lift means a spring. If the door hangs lower on one side, a cable has come off. A blinking light on the opener while the door refuses to close points at the sensors. For a new-door quote with no rush, email info@protechgarage.ca.
The price depends on the part. A torsion spring pair, a cable set, a gear kit and a new opener are four different bills, and a door that needs a spring often needs its cables at the same time. Ask what the visit and the part will cost when you call.
Every one of these has a page of its own, written for that place.

The van leaves from here. It is where the parts are, not a showroom you need an appointment for.
Answered for Ottawa specifically, not for everywhere at once.
It is not a homeowner job. A torsion spring on a double door is under enough tension to injure, and the spring pairing, the drum setting and the cable length all have to match the weight of that particular door rather than a generic figure. The truck carries torsion and extension springs, cables, rollers, hinges, drums and opener gear kits, and repairs are booked same day on (613) 845-9950.
A heavy steel, wooden or carriage-style door gets a 3/4 horsepower opener, and a lighter door does fine on 1/2. Get that wrong and the opener stalls partway on a cold morning after the door has been upgraded. Say what the door is made of and whether it is single or double. The two together set the answer.
Ask for rubber on the top, bottom and sides. PVC cracks as it ages. In a city where the bottom seal spends the winter against packed snow and ice, that is the joint most likely to fail first. It is a specification worth naming on the quote rather than leaving to whatever the installer has on the van.
Steel springs stiffen as the temperature falls and old grease thickens, so the opener works harder against a door that has not otherwise changed, and a spring that was already worn is likelier to let go on a cold morning. A lubrication and tune-up before the snow answers most of it. Keeping the bottom seal clear of packed ice answers the rest.
