There's a particular kind of morning that garage door technicians across Middlesex County know well: it's cold, it's early, and a homeowner just heard a loud bang from their garage. They go to check, press the opener button, and the door barely budges. or doesn't move at all. Nine times out of ten, a spring has broken.
It's one of the most common garage door emergencies in the area, and it's also one of the most predictable. Springs don't usually fail without warning. They give you signals for weeks or months before they go. The problem is most homeowners don't know what to look for.
This post is about changing that.
Before diving into warning signs, it helps to understand the job. Torsion springs (the horizontal coil mounted above the door opening) and extension springs (the springs that run along the side tracks on older systems) do the actual heavy lifting when your garage door moves. They counterbalance the weight of the door. which can be anywhere from 130 to over 300 pounds. so the opener motor just guides it rather than dragging it.
When springs are healthy, you can lift most garage doors manually with one hand. When they're failing or broken, the door becomes essentially dead weight. That sudden load transfer is also what destroys opener motors. they're not built to lift a full door unaided.
Springs are rated by cycles, not years. One cycle equals one full open-and-close. A standard spring is rated for around 10,000 cycles, which translates to roughly 7 to 10 years for a household using the door 2 to 4 times per day. High-cycle springs (rated for 25,000 cycles or more) last longer but cost more upfront. and are often a worthwhile investment for busy households.
Concord's climate accelerates spring wear in two specific ways. First, the extended winters mean more freeze-thaw cycling, and cold temperatures make metal more brittle. which is part of why spring failures cluster so heavily in late winter and early spring, when the steel is at its coldest and most stressed. Second, the region's high humidity (consistently above 60% relative humidity year-round) promotes corrosion. Rust weakens the metal at a structural level, making springs more prone to snapping even before they've hit their cycle limit.
Homes in neighborhoods like Conantum. bounded by the Sudbury River. or properties near Great Meadows or other low-lying wetland areas in Concord face more ambient moisture than homes on higher ground. If your garage isn't particularly well-ventilated, that moisture has nowhere to go, and it goes straight to your metal hardware.
Homeowners in nearby Lexington and Bedford see the same pattern. spring failures spike every March and April, when the combination of residual cold, moisture, and accumulated wear collides.
This is the most reliable early warning. Disconnect your opener by pulling the red emergency cord, and try to lift the door manually. It should rise smoothly and stay in place when held at waist height. If it feels unusually heavy, drops when you let go, or requires real effort to hold open, the springs are losing tension. Don't keep using the door in this condition. the added load is grinding down your opener motor every single time.
Some noise from a garage door is normal, especially in cold weather. But grinding, squeaking, or popping sounds that are new, persistent, or getting worse are signs that something is wrong. Grinding often points to metal-on-metal friction from springs losing lubrication or tension. Popping can indicate a spring that's close to snapping under load.
If you hear a sudden loud bang. sometimes described as a gunshot or firecracker. and your door stops working, a spring has almost certainly broken. Stop using the door immediately and contact a professional.
Take a look at your torsion spring above the door. Look for:
- Rust or discoloration on the coil surface. rust weakens the metal and dramatically shortens the spring's remaining life - A visible gap in the center of the spring. this is the clearest sign a torsion spring has snapped - Stretched or elongated coils. a spring that looks looser or longer than it used to is losing tension and nearing failure - Fraying cables near the spring drums. broken springs often cause the lift cables to go slack or detach
Monthly visual checks take about 30 seconds and can save you from an emergency call. You don't need to touch anything. just look.
If your door tilts to one side as it opens or closes. or jerks rather than moving in a smooth arc. one spring may have failed while the other is still functioning. This uneven load doesn't just look wrong; it puts abnormal stress on the tracks, rollers, and cables on the functioning side, and can trigger a cascade of secondary damage if left unaddressed.
If you notice your opener straining, humming louder, or stopping mid-lift, it's often compensating for a spring that's no longer doing its share of the work. Since openers aren't designed to handle the full weight of the door, this leads to premature motor burnout. which turns a spring replacement into a spring-plus-opener replacement. Catching the spring early avoids that compounding cost.
There are some spring-related maintenance tasks that are completely safe for homeowners: wiping dust off the hardware, applying a thin coat of lubricant to reduce friction and slow corrosion, and doing visual checks. These are genuinely useful.
What you should never attempt yourself is adjusting spring tension or replacing the springs. Garage door springs are under extreme mechanical tension. a torsion spring stores enough energy that when it releases unexpectedly, it can cause serious injuries. Broken fingers, lacerations, and worse are real outcomes of DIY spring work gone wrong. This is one of those jobs where professional tools, training, and experience aren't optional. they're the point.
When one spring fails, it's almost always worth replacing both at the same time. The surviving spring has been through the same number of cycles and will follow within months. Replacing both now avoids a second service call and keeps the door balanced.

Concord Garage Doors serves homeowners throughout Concord and surrounding towns. If your door is showing any of the warning signs above, don't wait for the spring to snap on a February morning. Check out our FAQ page for answers to common spring and repair questions, or reach out to get eyes on the system before it becomes an emergency.
Q: Can I still use my garage door if I think a spring is failing but hasn't broken yet?
A: Technically yes, but it's not a good idea. A weakening spring means your opener is carrying more of the door's weight than it was designed to, which accelerates wear on the motor and other components. More importantly, a spring that's close to breaking can snap suddenly and without much additional warning. If the door feels heavy, moves unevenly, or is making new noises, have it inspected before continuing regular use.
Q: How do I know if I have torsion springs or extension springs?
A: Torsion springs are the single (or sometimes double) horizontal coil mounted on a metal rod directly above the garage door opening. Extension springs run along the horizontal tracks on either side of the door. they stretch and contract as the door moves. Torsion springs are more common in newer and heavier doors; extension springs are typical in older systems. Both types wear out over time, but they show failure signs slightly differently.
Q: Does Concord's humidity actually affect spring lifespan?
A: Yes, meaningfully. Consistent moisture exposure causes rust and corrosion on the spring coils, which weakens the metal at a structural level and makes the spring more likely to snap before it reaches its rated cycle count. Keeping springs lightly lubricated reduces moisture contact and slows corrosion. but in a high-humidity environment like Concord, springs near or past the 7-year mark should be inspected annually regardless of how they look.
