Garage Door Spring Repair
Torsion and extension springs matched to the weight of the door, for two- and three-car garages around Southlake.
A snapped garage door spring cannot be patched; it has to be replaced with a spring sized to that door. The spring is the counterbalance. With a good one, a two-car door feels almost weightless by hand. With a broken one, you face the door's full weight, which on an insulated steel door can be well over a hundred pounds, and the opener was never built to lift that.
Torsion springs sit on a shaft above the opening and twist as the door rises. Extension springs run along the horizontal tracks and stretch. Both hold a great deal of stored energy, which is why DASMA's inspection sheet tells code officials to look at spring parts and not touch them. We choose the replacement by door weight, wire size, inside diameter and length, and we set the winding turns to the manufacturer's instructions; DASMA notes that paint or added trim raises a door's weight, and that wrong turns leave a door too stiff or drifting. Most springs are designed for 10,000 cycles, one cycle being a full open and close.
What a Failed Spring Looks Like
- A sharp crack from the garage, and afterward the door refuses to rise
- A split you can see in the spring coil overhead
- The motor hums along while the door hardly moves
- The door creeps up a little, then sinks again
- Cables hang slack or the door sits crooked after the bang
- Coils look dry, dull or pitted with rust
🔥 The North Texas Heat & Hail Factor
Springs here wear out on cycles, not on the calendar. The Census Bureau's 2020-2024 estimates show that three or more vehicles are parked at 38% of Southlake households and 34% of Colleyville households, and every driver adds another cycle to the door. A spring designed for 10,000 cycles, which Clopay gives as the usual design life, reaches that in about seven years at four cycles a day, and sooner in a busy household. DASMA adds that heat, moisture and rust shorten spring life, since rust pits become the starting point for fatigue cracks. So we ask how often the door runs and quote a higher-cycle spring when the arithmetic calls for one.
How Each Visit Works
Weigh and measure
We take the door's actual weight, spring wire size, inside diameter and length, because charts guess and heavy doors punish a guess.
Exact quote first
You approve one price for the correct spring set on site, before anything is unwound.
Replace and wind
Winding bars, the right number of turns, and new cables or hardware if the old ones are worn.
Balance check
The door must hold itself near half open with the opener disconnected, then it is cycled on the opener.
