What's involved
Garage Door Spring Replacement
A replacement spring restores the counterbalance that lets a sectional garage door move with manageable force. The work starts with the actual door, not just the old spring: door weight, height, track radius, cable drums, and shaft layout determine the correct spring specification. A spring that looks similar can still produce the wrong torque. We remove the failed or worn spring under controlled conditions, install a properly matched replacement, set tension, and confirm that the door is balanced before allowing the opener to move it again.

Symptoms
Signs You Need This Service
- A two-inch gap is visible in the torsion spring coil.
- The door will not stay open without the opener holding it.
- The opener rail flexes while attempting to raise the door.
- The door feels close to its full weight when disconnected.
- One spring is broken and the other appears stretched or rusty.
Repair or replace?
A standard residential torsion spring is commonly rated near 10,000 cycles. For a household opening the door several times a day, that often works out to roughly 7-12 years, although use and corrosion can shorten it. Replacement is the normal answer after a coil fractures. If the door has changed weight or the existing pair is mismatched, the replacement decision should account for the entire counterbalance system rather than copying the failed part.

Root causes
What Actually Goes Wrong
Normal metal fatigue
Spring wire is repeatedly wound and unwound as the door moves. Eventually the steel reaches its design cycle limit and fractures, often leaving a clear gap between two coils near the center.
Door weight changes
Added insulation, replacement sections, decorative hardware, or water-damaged panels can alter door weight. Springs selected for the original door may then be under- or over-sized for the load they must balance.
Corroded spring wire
Surface corrosion creates rough areas where stress concentrates during each cycle. It does not guarantee immediate failure, but corrosion can shorten the usable life of a spring, particularly when the garage stays damp.
Uneven paired springs
On a two-spring system, unequal spring force can leave the door off balance. One spring may have been replaced earlier with a different size, or one may have weakened enough to make the pair work unevenly.
Local conditions
Why This Matters in Mississauga
Many Mississauga households are now seeing original or first-replacement springs reach the end of their cycle life. This is especially common in west-end neighbourhoods such as Churchill Meadows, Lisgar, and Central Erin Mills, where homes built in the 1990s and 2000s may still have aging garage hardware. Calendar age is only a clue; daily use, a second vehicle, and frequent school or work trips affect cycle count. Measuring the current door is more reliable than assuming an old spring specification still fits.
Safety
What to Handle Yourself
Spring replacement belongs to the high-risk end of garage door work. Torsion springs store enough energy to move a heavy door, and the shaft, winding cone, cables, and drums can move suddenly when tension is released incorrectly. Do not substitute screwdrivers for winding bars, loosen set screws, or remove a cable while the spring is loaded. Submit the online form when ready for a spring replacement booking confirmed by email.
The visit
How We Work Through It
-
Identify door specification
We measure the door and review its lift hardware so replacement spring wire, inside diameter, length, and winding direction match the torque the system requires.
-
Unload old spring
The door is secured and the existing spring tension is released with the proper tools. Cables, drums, and shaft hardware are kept aligned during this controlled disassembly.
-
Install matched spring
The replacement is fitted to the shaft with its cones, bearing components, and drums correctly positioned. Hardware is secured before the spring receives any working tension.
-
Set and test tension
We wind the spring to the required setting, level the door through its travel, and test manual balance. Opener travel and reversal are checked only after the door moves smoothly on its own.
Questions
Garage Door Spring Replacement FAQs
How is the correct replacement spring selected?
The correct spring is selected from the door's measured weight and lift setup, Wire size, coil length, inside diameter, winding direction, drum type, and door height all affect torque. A matched spring lets the door stay balanced so the opener guides it instead of carrying it.
Can I open the door with a broken spring?
It is best not to. The door may weigh far more than expected and can move unevenly. A manually lifted door also creates a risk of dropping if your grip or the remaining hardware gives way. Keep it closed and arrange replacement through the online form.
Do two broken-looking springs always need replacement?
A visibly fractured spring requires replacement, while the other spring should be assessed for size, condition, and remaining serviceability. On paired systems, both have usually accumulated similar cycles. The recommended configuration should restore even torque and safe balance instead of leaving a mismatched counterbalance pair.
Will a new spring fix a noisy garage door?
It may fix noise caused by a failing or improperly tensioned spring, but not every sound comes from the spring. Dry rollers, worn hinges, tight bearings, and a damaged track can also make noise. The door should be checked through its full travel to identify any separate friction problem.
