Broken spring repair

Garage door spring replacement

Heard a loud bang from the garage and now the door won’t lift? A spring has almost certainly broken. We replace torsion and extension springs matched to your door’s weight, then balance and safety-test the door before we leave.

Signs a spring has broken

  • A loud bang from the garage, often when nobody was using the door
  • The opener strains, lifts the door a few inches, then stops or reverses
  • A visible gap in the coiled spring above the door
  • The door feels far heavier than usual when lifted by hand
  • Cables hanging loose beside the door

How it works

What to expect

  1. 1

    Secure the door

    We clamp the door in place and check the cables, drums and bearings before touching the spring.

  2. 2

    Match the spring to your door

    Springs are sized by the door’s weight and height. We fit the right wire size, length and cycle rating instead of a one-size-fits-all part.

  3. 3

    Wind, balance and test

    We wind the new springs, adjust the balance so the door stays put when half open, and test the opener’s force and safety reverse.

Pricing

What affects the price

Every job gets a written price before any work starts.

  • Torsion or extension springs, and how many your door uses
  • Door size and weight (a double door needs larger springs)
  • Standard or high-cycle springs
  • Whether cables, drums, rollers or bearings are worn too

FAQ

Common questions

Should both springs be replaced at once?

Usually, yes. Springs on the same door wear at the same rate, so when one breaks the other is close behind. Replacing both avoids a second visit and keeps the door balanced.

How long do garage door springs last?

Standard springs are rated for about 10,000 open-and-close cycles, roughly 7 to 10 years for most households. High-cycle springs last considerably longer and are worth it on a door you use many times a day.

Can I use the opener with a broken spring?

No. The opener is built to guide a balanced door, not lift its full weight. Running it can strip the gears or pull the door crooked. Leave the door closed until the spring is replaced.

What’s the difference between torsion and extension springs?

Torsion springs sit on a bar above the door and twist to lift it; they run smoother and last longer. Extension springs run alongside the horizontal tracks and stretch. Many older and lighter doors use extension springs, and converting to torsion is often possible.
