Protech Garage Doors supplies and fits garage door parts across Ottawa from 46 Grenfell Crescent in Nepean. Springs, cables, rollers, hinges, drums and opener gear kits ride on the truck, and the parts page says which of those are matched to the specific door and which a homeowner may fit. An Ottawa winter wears some parts out before others, and getting the right one to the door is the other half of the job.
A part comes to the door on the truck
Parts here are identified against the actual door and fitted on the service call. Whether a homeowner can collect one at Unit A on Grenfell Crescent is a question to ask on the phone. What you need when you call is not a part number. It is the door's width, the maker's sticker on the inside of a section (Garaga, Amarr and Stanley are the doors Protech installs, and Protech is a listed Garaga dealer), the brand on the opener head, and a photo of what broke. From those the right part is on the truck, and the repair page covers the visit.
The bottom seal, and March
The part that fails first in Ottawa is the rubber along the bottom of the door, and March is when it goes. Environment Canada's 1991 to 2020 normals for the airport give March a mean daily high of 2.4 and a mean daily low of minus 7.1: a thaw every afternoon and a freeze every night, for a month. Meltwater sits in the lip of the seal, freezes it to the slab, and the first opener cycle of the morning tears the rubber or lifts the screws out of the retainer. Two things follow. Knock the ice off the seal before pressing the button, because a door pulled off a frozen seal by the opener is the gear kit's problem next. And when the seal is replaced, have the retainer checked with it: a bent aluminium retainer will not hold a new seal flat, and the new rubber tears the same way the old one did.
Salt on the bottom section
The City of Ottawa spreads about 185,000 tonnes of road salt a year, the figure its program manager for operational research gave in December 2021. It comes home on the car, drips onto the slab, and the bottom section of the door stands in it from November until the driveway dries in April. The parts that live down there are the bottom brackets, the bottom pair of rollers, the lowest hinges and the foot of each track. Rust at a bottom bracket is the one to take seriously: that bracket anchors the lift cable under full spring tension, so a bracket that has rusted through is a cable job as well, and it is a service call rather than a part. The bottom rollers seize first for the same reason and are the first pair replaced. A hose on the inside of the bottom section on a mild day in March costs nothing and slows all of it down.
Springs on the 2000s subdivisions
Statistics Canada's 2021 count puts 86,735 of Ottawa's occupied dwellings in the years 2001 to 2015. Those are the doors whose original springs are reaching the end of their cycle count now; the spring page has the DASMA arithmetic behind that and why the spring is measured against the door rather than looked up. The 115,070 dwellings from 1961 to 1980 are the other end. A door from that era will have had its springs and cables changed at least once, and what is on it now was chosen by whoever fixed it last, so the sticker on the section may not match the hardware above it. Bring the photo.
Remotes, keypads and the detached garage
Remotes, keypads, rollers and weather seal are the parts a homeowner may fit. The one worth planning is the keypad. On a detached garage with no door into the house, the keypad on the jamb is the way in when the remote is in the car and the car is inside, and on a January morning at minus 14, the airport's mean daily minimum for the month, that matters. It pairs to the head at the visit, and a second remote is paired at the same time.

Answered for Ottawa, on the number this branch answers.
What do you need from me instead of a part number?
The width of the door, the maker sticker on the inside of a section, the brand on the opener head, and a photograph of what broke. Parts here are identified against the actual door and fitted on the service call. Those four things put the right part on the truck. Whether a homeowner can collect one at the unit on Grenfell Crescent is a question for the phone.
The bottom seal keeps tearing. Why does a new one fail the same way?
The retainer is bent. A bent aluminium retainer will not hold a new seal flat, so the new rubber tears exactly where the old one did. Have it checked whenever the seal is replaced. March is when this shows up. A mean daily high of 2.4 and a low of minus 7.1 is a thaw every afternoon and a freeze every night, for a month.
There is rust at the bottom bracket. Is that just cosmetic?
It is the one piece of rust to take seriously. That bracket anchors the lift cable under full spring tension, so a bracket that has rusted through is a cable job as well, and it is a service call rather than a part. The bottom rollers seize first for the same reason and are the first pair replaced. A hose on the inside of the bottom section on a mild March day slows all of it down.
