Garage Door Spring Repair
Coated torsion and extension springs, wound for the weight of your door and balance-tested before we go.
A broken garage door spring has to be replaced before the door is used again, and when the door has two springs, both should be replaced. Springs are the counterbalance: they carry the door's weight so the opener and your arms do not have to. Torsion springs sit on a shaft above the opening and twist; extension springs stretch along the horizontal tracks and must run over a safety cable. DASMA advises replacing both springs on a two-spring door even when only one has broken, which heads off damage when the second lets go; it has the same age and the same fatigue as the first.
Replacement is not a matter of matching the old spring by eye. DASMA lists the wrong door weight and the wrong number of turns among the installation errors that shorten a spring's life or make the job unsafe, so we measure wire size, inside diameter and length, weigh the door as it is now, with its paint, insulation and added hardware, and wind the new spring to the manufacturer's turn count. The finished door should stay put at three or four feet when you let go.
How a Broken Spring Shows Itself
- A bang from the garage like a gunshot
- A two-inch break shows in the coil over the opening
- The opener hums but the door lifts only inches
- The door feels twice as heavy by hand
- It slams down instead of lowering smoothly
- Spring coils that look dull, pitted or rusted
🌊 The Salt and Surge Factor
Clopay says springs break most often in cold weather; in Southwest Florida the usual causes are cycle count and corrosion. A standard spring is designed for about 10,000 cycles, which at four trips a day is under seven years, and moist salt air can start pitting the wire well before that. DASMA notes that corrosion pits are where fatigue cracks begin. In Estero, Naples, Marco Island and Fort Myers Beach, between 28 and 49 percent of housing units are used seasonally (ACS 2020-2024), and a door left fully loaded for months is not resting, so we fit coated springs and tell you the cycle rating of what goes in.
Replacing a Spring, Step by Step
Weigh and measure
Door weight, wire size, inside diameter and length are measured so the new spring matches the door as it is today.
Quote the exact set
One exact quote for the correct springs, approved by you before anything is unwound.
Replace under control
Winding bars, the correct turn count and a matched set go in; extension springs get a safety cable.
Balance and prove
The door must hold at half-open height, then the opener and auto-reverse are cycled and tested.
