The London branch replaces torsion and extension springs in London, Ontario and the towns it covers, sized to the door and in pairs where the door carries two, then winds and balances them on site. Repairs are booked the same day: call (226) 270-9715 or send the contact form. How the two kinds of spring work, and why winding one is never a homeowner's task, is on the spring repair page. A spring is rated in openings rather than in years, so two doors fitted on the same London street in the same year can reach the end of their springs a long way apart.
Springs wear by the count
A spring is rated in cycles, and DASMA, the door manufacturers' association, defines one as a door moving from closed to fully open and back to closed. A door opened for one commute runs 2 cycles a day, out and back, before errands. The 2021 census counted 138,155 London commuters, and 106,540 of them drove themselves. A household with two of those drivers sharing one garage puts at least 4 cycles a day on its door, so two doors installed on one street in the same year can wear out their springs years apart.
What shortens a spring
DASMA's technical data sheet on spring cycle life lists factors that sit with the household. Doors left open for long periods on a regular basis expose their springs to wider swings of temperature, moisture and air quality, and DASMA's advice is to keep doors closed where possible in places with extreme heat or cold or frequent precipitation. Paint or components added to a door can push it past what the springs were specified for, and an insulation kit glued to an old single-skin door is one such addition. Rust thins the wire and leaves pits where fatigue cracks start. And springs last longer lubricated as the door maker's instructions set out.
None of that is a repair to a spring. It is how the new pair outlasts the pair that broke.
The balance check, and where it ends
An opener maker's support pages describe a balance test that stays on the safe side of the line. With the door closed, disconnect it from the opener with the release, then lift it by hand 3 to 4 feet off the floor and let go. A balanced door stays where it is, supported by its springs, or drifts slowly. A door that slams shut or shoots upward is out of balance. The same pages say no one should loosen, move or adjust the springs, cables or pulleys, all of them under extreme tension. An out-of-balance result is a call to the branch, and a spring that has already snapped wants no test.
A spring that goes before 7 a.m.
In the 2021 census, 8,325 London commuters left for work from 5 to 5:59 a.m. and 23,385 from 6 to 6:59, and another 25,720 left between noon and 4:59 a.m. A torsion spring typically goes with a bang, and at those hours it can go with the car inside and the door shut in front of it. Leave the opener alone: running it with a broken spring strips its gear kit. Do not lift the door by yourself. If the car has to come out, two adults lift and the door is propped, as the spring repair page describes. The contact form can be sent from the driveway with a picture of the gap in the coil, and the repair is booked the same day.
Two towns that count higher
The towns show the same arithmetic. In Lucan Biddulph the biggest body of workers is trades, transport and equipment operators, and a good share of garages hold a work truck and a trailer, so the door runs several times a day. In Dorchester 1,440 of the 1,625 residents who commute drive, 435 commuters are out before 7, and 1,400 of 1,655 homes predate 2001. Name the town when you book.
What to send
How wide the door is, whether the springs sit on a shaft above the opening or run along the tracks and how many there are, a picture of the break, the town, and whether the opener was run after the bang. That gives the branch the picture before anyone drives out; the new springs are measured against the door itself when they are fitted.
If the springs turn out to be sound and the door still shudders, hangs low on one side or stalls, garage door repair in London, Ontario covers the roller, cable, sensor and opener faults the branch handles.

Asked before booking garage door spring repair
Answered for London, on the number this branch answers.
The spring went as I was leaving for work. What do I do?
Leave the opener alone, since running it with a broken spring strips the gear kit, and do not lift the door by yourself. If the car must come out, two adults lift and the door is propped, not balanced. Then send the contact form or call (226) 270-9715 with a picture of the gap in the coil; repairs are booked the same day.
How long should a new pair of springs last?
Count cycles, not years. A cycle is one trip from closed to fully open and back, and a door opened for two commutes and the errands runs several a day. DASMA lists what shortens spring life: doors left open for long periods, extra weight such as paint or components, rust, and skipped lubrication. If your door runs more than most, ask about a longer cycle rating when the pair is replaced.
Can I check whether my springs are weakening?
Yes, without touching them. With the door closed, pull the opener release, lift the door 3 to 4 feet by hand and let go. A balanced door stays put or drifts slowly; one that slams down or shoots up is out of balance. Adjust nothing under tension, and skip the test on a spring that has already snapped.
