Garage door spring repair in Mississauga
A broken spring in Mississauga is nearly always on a door from the building boom: Statistics Canada counts 47,955 homes built here in the 1980s, 46,745 in the 1990s and 23,530 between 2001 and 2005. Protech replaces torsion and extension springs across the city from Unit 14 at 1495 Bonhill Rd, in pairs matched to the door they go on. Repairs are booked same day. Send the contact form or email info@protechgarage.ca with the door's width and a photo of the spring above it.
The doors that break springs here
Erin Mills and Meadowvale went up through the 1970s, Lisgar from 1986, Churchill Meadows mostly between 1997 and 2001, and the city was largely built out by 2005. Where a two-car garage from those years carries one wide door, and that door is an insulated steel door, it is the heaviest thing that moves in the house, and the spring pair on it was sized to that weight. A door from 1999 in Churchill Meadows that has never had its springs changed is on a pair fitted twenty-seven years ago. A door from 1975 in Erin Mills is on its second or third set, and the question on the visit is whether the last pair was matched to the door or to whatever was on the truck that day. The spring repair page explains why a spring is measured rather than looked up, and why one is never replaced on its own.
Malton's Ridgewood and Marvin Heights streets from the 1950s, Applewood Acres by the QEW, and the older blocks of Port Credit and Streetsville are where the single doors are, and single doors of that age are where extension springs still turn up. Ask for the containment cable through each new one.
The one job to leave alone
The mechanics are on the shared page. What it cannot say is that on an attached Mississauga garage the door is a wall of the house, and a door that comes down out of balance comes down on the car, the slab, or the person crouched at the bottom bracket. A socket set and a second pair of hands do not make it a Saturday job. Prop the door if a car has to come out, leave the opener button alone, and send the form.
What Pearson's winter does to a spring
Environment Canada's 1991 to 2020 normals for Toronto Pearson, the station inside Mississauga, give January a daily high of -1.2 C and a daily low of -8.9. That is a freeze-thaw rhythm rather than Ottawa's deep freeze, where the January mean is -10.0. A spring cycled at -9 before work and near zero by the school run is worked at two stiffnesses a day, and a pair at the end of its life gives up in that swing. Lake Ontario keeps the nights warmer than inland: Pearson's coldest reading in the 1991 to 2020 record is -31.0 C, against -33.1 at Ottawa's airport.
Dock doors between Dixie Road and the airport
The unit sits in the Northeast Employment Area, among the distribution buildings between Dixie Road and Pearson, where Invest Mississauga counts more than 1,030 logistics businesses and the airport's cargo operation clears customs around the clock. A dock door there cycles more in a shift than a house door does in a month, so a spring on a receiving door is a lost-dock question rather than a parked-car one. When you write, give the door's duty: trucks a day, sectional or rolling steel, and whether the operator is a jackshaft on the wall. High-cycle springs exist for exactly that door and are specified to its cycle count rather than its size.
What to send
The width of the door, whether there is one spring or two above it, a photo of the gap in the coil, and whether the garage is attached to the house. Use the contact form or email info@protechgarage.ca. If the opener strained and stalled before you found the spring, say so: the opener repair page explains what that may have done to the gear kit.

Answered for Mississauga, on the number this branch answers.
Can I change the spring myself over a weekend?
No, and on an attached garage here it is the building that decides that, not the tool. The door is a wall of the house, and one that comes down out of balance comes down on the car, the slab, or the person crouched at the bottom bracket. A socket set and a second pair of hands do not make it a Saturday job. Prop the door if a car has to come out, leave the opener button alone, and send the form.
Why would a spring give out in a mild winter?
Because the swing works it, not the cold. Pearson reads a January daily high of minus 1.2 and a daily low of minus 8.9, so a spring cycled at minus 9 before work and near zero by the school run is worked at two stiffnesses a day, and a pair at the end of its life gives up in that rhythm. Ottawa deep freeze is a different mechanism.
What is a high-cycle spring and do I need one?
A spring specified to a cycle count rather than a door size, and on a receiving dock it is usually the right answer. A dock door between Dixie Road and the airport cycles more in a shift than a house door does in a month, so a spring on it is a lost-dock question rather than a parked-car one. Give the trucks a day, the door type, and whether the operator is a jackshaft on the wall.
