Springs
Springs carry the door's weight so the opener does not have to. We measure, match and wind new ones so the door sits balanced and moves smoothly.

Torsion springs wind up on a shaft over the opening, while extension springs stretch alongside the tracks. Either way, the springs rather than the opener carry the load.
When a spring weakens or breaks, the door turns heavy, jerks or refuses to rise. We measure wire size, length and diameter, choose a pair suited to your door's weight and how often it runs, then wind them until the door stays put halfway on its own.
When a torsion spring lets go it sounds like a dropped board or a gunshot. Afterward you may see a gap in the coil above the door.
Ask a technician to release the opener and lift the door. Strong resistance, or a door that crashes down, means spring tension no longer matches the weight.
Without spring help, the motor reaches its force limit a few inches up and stops or reverses, often with a loud hum.
Extension springs that look elongated, or a door that rises faster on one side, suggest worn tension and a balance problem worth correcting.
We record wire gauge, coil length and inside diameter, and consider door weight and daily use, so the new pair fits the load it will carry.
Tension is released with winding bars made for the job and the door is clamped. Cables, drums and bearings are inspected while nothing is under load.
We set the correct number of turns, test balance at several heights and run the opener to confirm quiet, even travel.
A standard spring is rated for about 10,000 cycles. Use the door a few times a day and that can mean several years, while heavy daily use shortens it. Higher-cycle springs use heavier wire and last longer when your door sees constant traffic.
On a two-spring door, usually. Both springs have cycled equally often, so the second tends to follow soon, and pairing old with new can leave the door lopsided. Should the remaining spring look noticeably newer, we mention it and leave the call to you.
Often, and it is worth considering on a heavy or noisy door. Torsion systems lift more evenly and are easier to balance precisely. It is not essential, since a well-sized extension setup with safety cables still works.
If a spring has gone, keep the door closed and the opener off. Describe what you heard and we will explain what the replacement involves.
