GARAGE DOOR SPRING REPAIR · MOCKSVILLE & THE TRIAD, NC
BROKEN SPRING? DON'T TOUCH IT.
That loud bang from the garage was probably a spring letting go. The door now weighs a couple hundred pounds with nothing helping lift it. Leave it down, call us, and we'll handle the dangerous part.
WHAT WE DO.
- Torsion and extension spring replacement
- Both springs replaced, not just the broken one
- Spring tension adjustment and balancing
- Safety cable installation
- Same-day service in most cases
- Residential and commercial doors
HOW YOU KNOW A SPRING IS GONE.
- A loud bang from the garage, like something snapped. It did.
- The opener strains, then gives up, or the door only lifts a few inches.
- A visible gap in the coil above the door.
- The door slams down faster than it should, or sits crooked in the tracks.
- Lifting it by hand suddenly feels like a deadlift.
Springs do the actual lifting on a garage door. The opener just tells them when. Every open and close counts as one cycle, and standard springs are built for about 10,000 of them, so after seven to ten years a break isn't bad luck. It's arithmetic.
When one spring breaks, its partner has the same mileage. Replacing only the broken one means the old spring drags the new one out of balance and puts you right back where you started in a year or two. We replace both, set the tension to your door's actual weight, and test the balance before we leave.
A word of caution: a wound torsion spring stores enough force to break a hand. It's the one garage door job you should never try with a YouTube video and a socket set. Our technicians do it with winding bars, the right way, every week of the year.
Every spring replacement is backed for 5 years or 10,000 cycles, whichever comes first.
HOW SPRINGS ACTUALLY WORK.
Torsion springs
Torsion springs mount on a steel shaft above the door. As the door closes, the cables wound on drums at each end of the shaft twist the springs tighter, storing the energy that lifts the door on the way back up. When a torsion spring breaks, the coil separates and you can usually see a gap of an inch or two. That gap is the bang you heard.
Extension springs
Some doors, often older or lighter ones, use extension springs that stretch along the horizontal tracks on each side. They do the same job a different way, and they need a safety cable run through the middle so a broken spring can't whip across the garage. If yours don't have safety cables, we install them.
Sizing a spring to the door
A spring is matched to the door by wire size, length, inside diameter, and the weight it has to balance. An insulated door or a door with windows weighs more than a plain steel door of the same size and needs a different spring. We size to the actual door, then fine-tune the tension until the door, disconnected from the opener, holds still about halfway up. That's what balanced looks like.
Right after the bang
Leave the door closed if it's closed. Don't pull the red emergency release while the door is up, because without a working spring it can drop. Don't keep pressing the opener button either; the motor is now trying to lift the whole door and can strip its gear. Our loud bang guide walks through it.
Cables go with springs
A spring break often throws the lifting cables off their drums, and a cable that has sat slack can kink or fray. When we replace springs we check the cables, drums, and bearings at the same time and replace what's worn, because a new spring on a frayed cable is just the next service call. If a cable is hanging loose, read what to do when a garage door cable snaps.
Making new springs last
A spring's life is counted in cycles, so the biggest factor is how often the door runs. A light coat of garage door lubricant on the coils once or twice a year cuts friction and rust, and a yearly garage door tune-up catches a spring that's losing tension before it lets go. High-cycle springs make sense for doors that run all day.
Across the area, parts on the truck
Spring replacement is routine work for us from Mocksville and Advance to Clemmons, Lewisville, and Lexington. The common spring sizes ride on the truck, so most spring jobs are same-day and done in one visit, with the door balanced and cycle-tested before we leave.
STRAIGHT ANSWERS.
REVIEWED OCTOBER 2026
How long do garage door springs last?
A standard spring is rated for about 10,000 open-and-close cycles. For most families that works out to 7 to 10 years. Park outside and it lasts longer; kids running the door all day, shorter. Ours are backed for 5 years or 10,000 cycles.
Should I replace both springs or just the broken one?
Both. They were installed the same day and carry the same mileage, so the survivor is usually weeks from its own bang. Doing both in one visit costs far less than two service calls.
Can I replace a spring myself?
This is the one garage door job we genuinely tell people not to try. A wound torsion spring stores enough energy to break an arm, and winding it takes proper bars and practiced hands. Call us; it's a same-visit fix.
Why does my door feel heavy when the spring isn't broken?
Springs lose tension with age before they break. If the door feels heavier than it used to, or won't stay put halfway up when it's disconnected from the opener, the springs are weakening. Re-tensioning or replacing them is a job for someone with winding bars.
