Garage door spring repair is the call we get most after a cold night. A torsion spring that snaps sounds like a gunshot in the garage, and afterward the door feels as heavy as a car hood. In Bryn Mawr and Rosemont, Hemlock replaces broken springs and sets the tension so the opener is not doing the lifting.
Please do not try to lift the door by hand or keep pressing the button. The opener can strip its gear trying to raise a door with no spring help. Leave it closed, keep the car where it is if you can, and call us.
Signs You Need Garage Door Spring Repair
- A gap of a few inches in the spring above the door
- The door rises a little, then the opener stops and hums
- The door slams down when you let go halfway
- Cables hang slack after a loud bang
Why Springs Break in Winter Here
Springs are steel that wears out with use, and cold makes the metal less forgiving. A spring near the end of its life often gives out on the first cold morning of the season. If one spring on a two-spring door breaks, we talk to you about the other one, since it has done the same work.
How We Handle It
Make it safe
We clamp the door so it cannot drop while we work.
Measure the old spring
Wire size, length and inside diameter are matched to your door's weight.
Install and wind
The new spring is wound to the right number of turns.
Balance test
The door should stay put halfway open when released.
