Garage Door Torsion Spring Replacement in Floral Park

How to spot a broken torsion spring

Stand inside the garage with the door closed and look at the bar above the opening. A healthy torsion spring is one continuous coil. A broken one shows a clear gap, usually a few inches wide, where the coil has separated. You may also notice:

• cables that hang loose from the drums at the top corners,
• an opener that hums or lifts the door only a few inches,
• a door that sits crooked or feels extremely heavy.

If you see the gap, unplug the opener and call. Running the opener against a door with a broken torsion spring can bend the top section or wreck the opener's gear.

One spring or the pair?

Doors with two torsion springs split the load between them. They were installed together and have done the same number of cycles, so when one breaks the other usually is not far behind. Replacing both from $375 saves a second visit and keeps the door lifting evenly.

A lighter single-car door may run on only one spring. In that case one new spring from $175 is the whole job. We will tell you which you have before quoting.

How we install a torsion spring

1. Clamp the door down and release any remaining tension safely.
2. Measure the old spring and weigh the door's needs.
3. Slide the new spring onto the shaft, set the cable drums and wind with proper bars.
4. Even out the cables, lubricate the coils, and test the balance halfway up.
5. Reconnect the opener and check the auto-reverse.

While the bar is apart we look at the center bearing, the end bearing plates and the drums. Worn bearings make a door noisy and put extra load on the new spring.

Parts that wear out next to the spring

A torsion spring does not work alone. It turns a steel shaft that carries two cable drums, one at each end, and the shaft spins in bearings mounted to the wall. When we replace a spring, we look at each of these:

• Cable drums: grooves should be clean and the set screws tight; a cracked drum can let a cable slip.
• Bearings: a dry or seized end bearing makes a grinding sound and loads the spring unevenly.
• Lift cables: fraying at the bottom brackets is common on older doors and is easy to miss.
• Center bracket: it must be anchored firmly, since it holds the fixed end of the spring.

We do not replace anything on that list without showing you why and giving you the price first.

Was the old spring the right size?

Sometimes the spring that broke was not correct for the door in the first place, especially after an earlier quick repair. Signs include a door that never stayed put halfway, or an opener that always seemed to struggle. Measuring the door rather than copying the old spring fixes that for good.

Torsion springs in Floral Park garages

Torsion systems need a bit of headroom above the door, so they are more common on attached garages and on doors that have already been replaced with newer models. On a back-of-the-lot garage from the 1920s or 1930s with a low header, we sometimes find extension springs instead, or a low-headroom torsion kit. If yours looks different from the description here, see extension spring repair.
