Carter Garage Door & GatesSprings do the heavy lifting on a sectional garage door. The opener mostly steers the motion; the coiled steel on the shaft above the door, or the long springs stretched beside the tracks, counterbalance nearly all of the door's weight. Once one of them fails, the door suddenly feels like what it really is: a heavy slab of steel or wood.
Hudson County and Bergen County garages go through regular freezing nights each winter, plus damp, salty air carried in from plowed streets. That mix is hard on spring wire. Below we break down the mechanism, the symptoms, and what a technician actually does on a spring replacement visit.
Why cold weather and broken springs go together
Residential springs are built for a limited number of open-and-close cycles. Door makers commonly cite about 10,000 cycles for a standard spring, counting one trip up and back down as a cycle. Each cycle twists or stretches the coil, and tiny fatigue cracks slowly form in the wire. Cold weather doesn't start that clock, but it can finish it.
- Steel turns less forgiving. Low temperatures make spring wire more brittle, so a coil near the end of its life is more likely to crack than flex.
- Lubricant thickens. Grease on rollers, hinges and bearings stiffens in the cold, so the whole system resists every movement a little more.
- Hardware drags. A bottom seal frozen to the slab, tight rollers and rusty bearings all add load that the spring and opener have to fight.
- Moisture and road salt. Slush dripping off tires raises humidity in the garage, and rust pits on the coil become weak points.
Think of cold as the trigger rather than the root cause. A spring that snaps in February had usually used up most of its cycle life already; the freeze just pushed it past the edge.
Signs a spring is worn out or already broken
Some symptoms appear weeks before a failure. Others mean the spring has already let go.
| What you notice | What it usually points to |
|---|---|
| A loud bang from the garage, then the door won't open | A torsion spring has snapped; look for a gap in the coil above the door |
| The opener hums or strains, and the door rises only a few inches | Lost spring tension; many openers stop or reverse when the load is too heavy |
| The door slams down or feels very heavy by hand | The springs no longer balance the door's weight |
| One side lifts higher than the other | One spring broken on a two-spring setup, or a cable problem on that side |
| Stretched or unevenly spaced coils on side-mounted springs | An extension spring that has lost its shape |
| Flaking rust or a visible crack on the coil | Corrosion or fatigue that can lead to a break |
A broken torsion spring is usually easy to spot from the floor, because the coil splits into two pieces with an obvious gap. Extension springs run along the horizontal tracks and should have a safety cable threaded through them. If one breaks without that cable in place, the pieces can whip across the garage.
What to do right after a spring breaks
- Stop pressing the remote or wall button. Running the opener against a dead spring can strip gears, bend the top section or pull the rail loose.
- Leave the red emergency release alone if the door is open. With no spring tension, a door disconnected from the opener can drop hard.
- Keep kids and pets out of the doorway until the door is secured.
- If a car is stuck inside, mention it when you call so the door is handled first.
- If you can see them safely, snap a photo of the springs; it helps identify the right replacement.
Torsion springs are wound under heavy tension, and the winding cones and set screws hold that stored energy. Loosening the wrong part can spin a winding bar out of your hand. Lift cables and bottom brackets carry the same load, so leave them alone too.
What a spring repair visit covers
Garage door spring repair is rarely a straight coil swap. The tech sizes the replacement to the door itself, not only to the old spring, because doors gain weight when panels are replaced or insulation is added.
Matching the spring
- Wire size, inside diameter and length of the coil
- Wind direction (left- or right-hand) for torsion springs
- Door weight, height and the drum or pulley setup
Checking the rest of the system
With tension off, it's a good moment to inspect the parts that move with the spring: lift cables for fraying, drums for cracks, end bearings, and rollers. A frayed lift cable is worth replacing in the same visit, since it carries the load the new spring creates.
Balancing and testing
Once the new springs are wound, a balanced door should stay roughly in place when lifted halfway by hand. The opener is then reconnected, and the auto-reverse and photo-eye tests are run before the visit wraps up.
On doors with two torsion springs, many technicians suggest replacing both together. Both coils have lived through identical use, which means the one still intact tends to fail soon after.
Habits that ease the load through a North Jersey winter
- Glance at the springs once a month from the floor. Gaps, rust or stretched coils are easier to catch before a cold front rolls in.
- Lubricate springs, hinges and steel roller bearings in late fall with a product made for garage doors, not heavy grease.
- Free a frozen bottom seal before opening; chip the ice away instead of letting the opener tear it loose.
- Run a balance check: pull the release with the door fully closed, lift by hand to waist height, and see whether it holds. A door that drops fast or shoots upward needs adjustment.
- Book a tune-up if the door has become louder or slower. A general garage door repair visit can look at springs, rollers and the opener together.

Frequently asked questions
Do garage door springs really break more in winter?
They tend to. Cold makes spring steel more brittle and stiffens lubricants, so a worn spring that might have lasted a little longer in mild weather is more likely to crack on a cold morning. The underlying cause is still fatigue from years of cycles.
Can I lift the door by hand with a broken spring?
It's not a good idea. Without spring tension you're lifting the full weight of the door, and if your grip slips it comes down hard. If a car has to come out, call and describe the setup so a technician can secure the door or replace the spring first.
Should both springs be replaced if only one broke?
Usually, on doors with two torsion springs. Both have done the same work, and pairing a brand-new spring with a worn one can leave the door out of balance. The tech will show you the condition of the remaining spring before you decide.
How can I tell torsion springs from extension springs?
Torsion springs sit on a metal shaft directly above the closed door, usually on either side of a center bracket. Extension springs run alongside the horizontal tracks and stretch as the door closes. Both kinds can be replaced; the parts and steps differ.
