Extension Spring Replacement in Miami-Dade & Broward

Extension springs are the long springs that stretch along the tracks on each side of the door. We replace both together and balance the door, the same day — with the safety cables checked so a spring can never whip loose.

Do you have extension springs?

Look at the horizontal tracks that run along the ceiling on each side of the door. If there is a long spring stretched along each track — usually with a pulley and cable at one end — you have extension springs. They are common on older South Florida homes and on many single-car doors. If your spring sits on a bar above the door instead, you have a torsion spring.

Why both springs are replaced together

The two springs share the door's weight. If only one is replaced, the new spring pulls harder than the old one and the door lifts crooked, which wears the cables, rollers and opener. Replacing and balancing both keeps the door running straight.

The safety cable matters

When an extension spring breaks, it releases its energy all at once. A safety containment cable runs through the middle of each spring so that, if it ever snaps, it stays on the cable instead of flying across the garage. Plenty of older doors are missing them. We check every one and make sure yours are in place before we leave.

Signs an extension spring broke

  • A loud bang, and a spring hanging loose or lying on the floor
  • The door lifts crooked, or only one side rises
  • The door feels very heavy, or the opener strains and stops

Stop using the opener and keep everyone away from the door until it is fixed.

Extension Spring Replacement FAQ

Should I switch from extension springs to torsion springs?
Extension springs work well when they are sized correctly and have safety cables. A conversion is sometimes worth it on a heavier door — we will tell you honestly if it makes sense for yours, and we always quote both options.
Can I replace just one extension spring?
We don't recommend it. A new spring and an old spring pull differently, so the door lifts unevenly. Replacing both keeps it balanced.
How long does it take?
Usually about an hour, including balancing and testing.

The New Standard Promise

The price we quote is the price you pay — even if we find more. Every job starts with a free 25-point inspection and an honest written report, and any extra repairs we discover are done at no additional cost.
