A broken spring is a common reason a garage door stops lifting. In an attached garage or a detached single-car garage, the door may become difficult to move, and the opener may strain against its weight. If you hear a sharp pop or see a gap in a coil, leave the spring hardware alone and keep clear of the door.
In Mecklenburg County, our crew repairs torsion and extension spring systems. Torsion springs mount on a bar over the doorway, twisting to offset the door’s weight. Extension springs stretch along the horizontal tracks as the door moves, with safety cables running through them to help contain a spring if it breaks.
We measure the door’s weight and height, drum size, and spring wire size to choose suitable replacements. On a door with two springs, we generally replace the pair so the lift remains even. Our truck carries common spring sizes, safety cables, and winding bars. We use winding bars—not screwdrivers—to handle torsion springs. At the visit, we review the work and provide an exact quote before beginning. Once work is complete, we check the door’s balance and confirm that its safety reversal works.
Signs You Need Garage Door Spring Repair
- I heard a sharp pop, and now the door stays shut.
- I can see a break between coils above the door.
- The opener runs, but the door barely rises.
- The door starts up, then stops partway.
- One side of the door lifts ahead of the other.
- I have to strain to raise the door by hand.
The Charlotte Freeze Factor
Across Mecklenburg County, winter nights average about 34°F, and cold weather can change how spring hardware and moving parts behave. Metal contracts, springs become less flexible, and lubricant may thicken, adding friction as rollers travel. After replacing a spring, our crew checks that the door moves freely rather than treating the spring as the only possible source of strain. We also look for brittle seals or ones that have stuck to the floor, so you know whether the repair involves just the spring or another part of the door system.
How We Handle It
Tell us what the door is doing
A crew member takes your call and notes what you heard, saw, or noticed when the door stopped working. Those details help our crew prepare for the visit.
Inspect and quote
We examine the spring system and the door’s measurements. At the site, we provide an exact quote and get your approval before starting the repair.
Replace the failed parts
We fit springs to the door’s weight, height, drum, and wire size. If the door uses two springs, we generally replace both to keep the lift balanced.
Test the door
We check the door’s balance and movement, then place a 2-inch wooden block in its path to confirm that it reverses on contact. We make any needed adjustments before leaving.
