Garage Door Spring Repair in Attleboro, MA
A broken spring is the most common reason a garage door suddenly won't lift. We replace torsion and extension springs for Attleboro homes and balance the door so the opener isn't doing the spring's job.
Signs your garage door spring has broken
Springs rarely fail quietly. Most homeowners notice one of these first.
- A loud bang from the garage, often on a cold morning.
- The door rises a few inches and stops, or the opener strains and reverses.
- A visible gap in the coil of the torsion spring above the door.
- The door feels far heavier than usual when lifted by hand.
- The door drops fast over the last foot of travel.
Torsion springs vs extension springs
Torsion springs
Mounted on a steel shaft above the door opening. They twist to store energy and turn the cable drums as the door moves. Most modern sectional doors use them.
Extension springs
Run along the horizontal tracks and stretch as the door closes. Common on older and lighter doors. They should always have a safety cable running through them.
Why springs wear out, and why we replace them in pairs
Every spring is rated for a number of open-and-close cycles. A standard spring is often rated around 10,000 cycles, which a busy household can use up in several years.
When a door has two springs, they have done the same work. If one has broken, the other is usually close behind, so replacing both keeps the door balanced.
Cold-weather spring failures
Steel is less forgiving in the cold and lubricant thickens, so a tired spring often gives out on the first hard freeze of an Attleboro winter.
Rust from road salt and damp garages weakens coils over time. A light coat of garage door lubricant each fall helps.
Please don't adjust a torsion spring yourself
A wound torsion spring holds enough force to lift the entire door. Loosening the set screws on the winding cone without proper winding bars can break bones or send a tool flying. If a spring breaks, leave the door where it is and unplug the opener.
How spring repair works with us
Inspect
Check springs, cables, drums, bearings and rollers for related wear.
Measure
Match wire size, length and inside diameter to the weight of the door.
Replace
Unwind safely, fit the new springs and wind them to the correct turns.
Balance
Test the door by hand at mid-height and adjust until it holds.
Repair the spring, or replace more?
A broken spring on a sound door is a repair, not a reason to buy a new door. Look at other work when cables are frayed at the bottom brackets, rollers are cracked, or panels are rusted through.
