Garage Door Spring
Repair & Replacement

The springs do all the heavy lifting on a garage door. They counterbalance somewhere between 90 and 180 kg of door, twice or more every day, and after 10,000 to 15,000 cycles (call it 7 to 12 years of normal use) the steel simply fatigues and lets go, usually with a bang people mistake for a firecracker. Once that happens, the opener alone cannot lift the door safely.

Summit Premium Services replaces torsion and extension springs across the GTA the same day you call. Our vans carry the common spring sizes, and we always match the replacement to your door's actual weight and track setup. A wrongly sized spring throws off the balance, wears out the opener and fails early, which is why we're fussy about it.

Signs Your Spring Is Broken (or About to Break)

• Loud bang heard from the garage
• Visible gap in the coil above the door
• Door lifts a few inches, then stops
• Door feels extremely heavy by hand
• Door slams down or won't stay open
• Cables look loose or hang off the drum
• Door lifts crooked / one side higher
• Squealing or straining opener

Torsion vs. Extension Springs

Torsion springs sit on a shaft above the door and twist to lift it. They're standard on most GTA homes built since the 1980s, run smoother and last longer. Extension springs stretch along the horizontal tracks, mostly on older or low-headroom garages. We service both. When we replace extension springs we always add safety cables, so if one ever breaks again it can't whip across the garage.

Should You Replace One Spring or Both?

On a two-spring door, our advice is to do both when one breaks. They have identical mileage, so the survivor usually follows within months, and until then the door runs unbalanced. Doing the pair in one visit is cheaper than two separate calls. For busy households and commercial doors we also carry high-cycle springs rated for 25,000+ cycles.
