Your garage door opener gets all the credit, but it's actually the springs doing most of the work. Every time that door goes up, the springs are counterbalancing hundreds of pounds of door weight. and they do it thousands of times over their lifespan without you giving them a second thought. Until they fail.
In Concord, spring failures are more common than people expect. The combination of cold winters, significant temperature swings between seasons, and homes with attached garages that see heavy daily use all add up to accelerated spring wear. This guide gives you the honest picture. what springs actually do, what the warning signs look like, and when you need to call someone.
Most residential garage doors use one of two spring systems: torsion springs, which mount horizontally above the door opening on a metal shaft, or extension springs, which run along the horizontal tracks on either side. Both work by storing mechanical energy as the door closes, then releasing it to help lift the door open.
Without functioning springs, your opener is trying to move a 150- to 300-pound door on its own. something it's not designed to do. A door with failed springs either won't open at all, or it'll open very slowly with the opener straining audibly.
Standard garage door springs are rated for approximately 10,000 cycles. One cycle equals one full open and one full close. For a household that uses the garage door 3 to 4 times per day. pretty typical in Concord neighborhoods like Concord Heights and the South End where most homes have garages as the primary entry point. that works out to roughly 7 to 9 years.
Heavy use shortens that window. Extreme temperature changes also accelerate wear. If you've had your springs for more than seven years and haven't had them inspected, it's worth taking a look. Replacing springs on a planned schedule is far less disruptive than an emergency replacement when a spring snaps without warning.
For context on the bigger picture of what your garage door system should include, take a look at our homeowner feature checklist.
Disconnect the opener using the red emergency release cord and try to lift the door manually. It should move with reasonable ease and stay in place when you stop at mid-height. If it feels unusually heavy or drops when you let go, the springs are likely worn and no longer counterbalancing the door's weight correctly.
A spring breaking under tension can sound like a gunshot or a car backfiring. sudden and sharp. If you heard something like that from the direction of your garage and your door stopped working afterward, a spring almost certainly snapped. Stop using the door and call for service. Continuing to operate a door with a broken spring puts serious stress on the opener and cables.
If one spring fails while the other is still functional, the door will tilt to one side as it opens or closes. This uneven strain also damages cables, tracks, and rollers over time. A door that looks crooked when it moves. even slightly. warrants a closer look.
Take a look at your torsion spring above the door. A healthy spring has tightly wound coils with no visible gaps. If you see a gap in the coil, the spring has snapped and needs immediate replacement. Rust is also a serious warning sign. moisture causes corrosion that makes the metal brittle and prone to sudden failure. In New Hampshire's humid summers and wet springs, this is a real concern for springs that haven't been maintained.
If your opener sounds like it's working harder than usual, hums, or stops partway through lifting the door, it may be compensating for failing springs. Openers aren't built to handle the full weight of the door. pushing them to do so burns out the motor prematurely. Don't ignore this symptom.

This one isn't a disclaimer for the sake of it. it's practical advice. Garage door springs are under significant mechanical tension, storing enough energy to cause serious injury when released improperly. Replacing them requires specialized winding bars, knowledge of the correct spring size for your door's weight, and experience handling the tension safely.
A door without spring support can drop suddenly and without warning. That's a 200-pound panel moving at speed. Even experienced DIYers get hurt attempting this repair. Leave it to a trained technician. the job typically takes 60 to 90 minutes when done properly and the peace of mind is worth it.
Garage Door Concord serves homeowners throughout the area, including in Merrimack and Hooksett, and we see the aftermath of DIY spring jobs more often than we'd like.
Delaying spring replacement doesn't just risk a broken spring. it risks a chain reaction of damage. A weak spring forces the opener motor to overwork, shortening its lifespan. The cables can go slack or snap. Tracks can warp from uneven stress. What could have been a straightforward spring replacement becomes a more involved repair.
If you're noticing any of the signs above, the right move is to schedule an inspection before the failure becomes an emergency. Our service areas page covers all the communities we work in across the Concord region.
Q: Can I replace just one spring, or do both need to be replaced at the same time?
A: Always replace both springs at the same time, even if only one has broken. Springs on the same system wear at similar rates, and the intact spring is likely close to failure as well. Replacing both ensures even tension and prevents a second emergency service call a few months later.
Q: How do I know if I have torsion or extension springs?
A: Torsion springs are mounted horizontally on a rod directly above the garage door opening. you'll see one or two coiled cylinders running across the top. Extension springs run along the horizontal tracks on either side of the door and look like long, stretched coils. Extension springs are more common in older homes; many of Concord's colonial and Cape Cod-style homes built before the 1990s still have them.
Q: Is a spring replacement covered by a home warranty?
A: It depends entirely on your plan and provider. Many standard home warranties cover garage door openers but exclude springs as a wear item. Check your policy details, and when in doubt, call your warranty company before scheduling service so you know what to expect on cost.
