Garage Door Spring Repair
Springs are sized from the door's measured weight, fitted in matched sets and checked for balance before the opener goes back on.
A garage door spring that breaks lets go with a bang loud enough to send people out to check the car, and then the door will not lift: the spring was carrying most of the door's weight, and the opener was never built to take it. A torsion spring rides on a bar over the opening and stores energy by twisting; an extension spring sits beside each horizontal track and stores it by stretching. Either one can hurt someone badly, which is why a wound spring is not a weekend job.
We size the replacement from the door itself, not from a chart: measured weight, wire size, inside diameter and length, with paint, insulation and added trim counted in. The door industry's trade group warns that a spring chosen for the wrong door, or a door made heavier by paint or add-ons, wears out early. On a two-spring door we replace both together, set the correct number of turns, and prove the door balances at half-open before the opener is reconnected.
Signs a Spring Has Let Go
- A gunshot crack in the garage, and the door will not rise
- A visible gap in the coil above the door
- The opener runs but the door barely lifts
- The door feels very heavy when you lift it by hand
- The door drops fast instead of lowering smoothly
- Cables hanging slack beside the door
Rust and Spring Life
Rust is the quiet cause behind many breaks. The door industry's own data sheet on spring life explains that rust cuts into the spring wire and leaves corrosion pits, and fatigue cracks grow from those pits, so a spring can fail well before its rated cycles. A bare torsion spring on a barrier island hangs in air carrying sea-spray chlorides, which speed up corrosion on plated steel. We fit coated or galvanized springs here, lubricate them as the door maker's instructions call for, and look for pitting on the old spring so you can see the cause for yourself.
How We Handle It
Weigh and measure
Door weight, spring wire size, inside diameter and length are measured so the new springs match the door as it is today.
Exact quote first
The correct spring set is priced on site and you approve it before anything is unwound.
Safe replacement
Winding bars, the correct number of turns and matching hardware, installed to the door maker's instructions.
Balance proof
The door must float at half-open and hold, then it is cycled on the opener with the safety reversal tested.
