Garage door springs don't announce their retirement plans. One day your door is working fine. The next morning you press the button, hear the opener run, and the door doesn't move. or worse, you hear a sharp bang that sounds like something heavy fell off a shelf. That's a broken spring, and it happens to homeowners in Wolfeboro every week.
This post is for homeowners who want to actually understand what their springs do, how to recognize when they're failing before they snap, and what the replacement process looks like. No fluff, no upselling. just straight information.
Torsion springs are the horizontal coils mounted above the door opening. They're the standard in most modern garages and are what you'll find on the vast majority of homes built or renovated in Wolfeboro and surrounding communities like Meredith and Laconia over the past few decades. When the door closes, these springs wind up and store tension. When you open the door, that stored energy unwinds and does the heavy lifting. counterbalancing a door that can weigh anywhere from 150 to 300 pounds.
Extension springs run along the sides of the door tracks and stretch as the door closes. They're more common in older homes and are still found in some of the pre-1980s construction you'll see throughout the area. They work the same way conceptually, but they require safety cables to prevent them from becoming projectiles if they snap.
The key point: your opener is not designed to lift the full weight of the door. The springs do that work. When the springs are weakening, your opener compensates by straining harder. and that shortens the opener's life, too.
Springs are rated by cycles, not years. One cycle equals one full open-and-close. A standard spring is rated for roughly 10,000 cycles. For a household that uses the garage door 3,4 times a day. which is common for families using the garage as their primary entry point. that translates to about 7 to 9 years.
In practice, springs in this region can wear faster than average. Wolfeboro's climate cycles between extremes: summers that reach the upper 70s and winters that regularly bottom out in the teens. That thermal cycling stresses metal over time. High humidity compounds it. moisture exposure accelerates rust, and a rusty spring is more brittle and prone to snapping.
If your springs are approaching that 7,9 year window, it's worth getting them inspected proactively rather than waiting for a failure. See our FAQ page for more on what a routine spring inspection involves.
Springs rarely fail without warning. you just have to know what to look for.
Disconnect your opener and try lifting the door manually to waist height. It should feel relatively light and stay put when you let go. If it feels like you're lifting dead weight, or if it slowly drops when you release it, the springs are no longer properly counterbalancing the door's weight. This is one of the clearest early warning signs.
If your door tilts to one side as it opens or closes. one corner rising faster than the other. that typically means one spring has failed while the other is still functional. The door is being pulled unevenly. This creates stress on cables, tracks, and rollers that can cause secondary damage quickly.
Look at your torsion springs monthly. A healthy spring has tightly wound, evenly spaced coils. Warning signs include: - Rust or discoloration on the spring surface. weakens the metal significantly - A visible gap in the coils. the spring has already snapped - Elongated or stretched coils. the spring has lost proper tension
Given Wolfeboro's year-round humidity (rarely dropping below 77%), rust is a genuine concern even in garages that stay relatively dry. Applying a light coat of lubricant to your springs during regular maintenance helps slow the corrosion process.
A squeaking spring isn't always an emergency. sometimes it just needs lubrication. But persistent grinding, popping, or a sudden loud bang are different. A spring snapping under tension releases a sharp crack that travels through the garage. If you hear that sound and your door stops responding, don't try to force it.
If your opener is making more noise than usual, seems to hesitate before lifting, or stops mid-travel, it may be compensating for a weak spring. Openers aren't designed to handle the door's full weight, and using one with a failing spring will burn out the motor prematurely.
This comes up every time: can a reasonably handy homeowner replace garage door springs? Technically, the answer is yes. Practically, the answer is that you shouldn't.
Torsion springs are under extreme mechanical tension. enough to cause serious injuries if released improperly. The job requires specific winding bars and techniques. A door without spring support weighs 150 to 300 pounds and can drop suddenly. This is one of the few home repairs where the professional recommendation isn't about protecting business. it's genuinely about safety.
Wolfeboro Garage Doors handles spring replacements with the right tools, and most jobs take 60 to 90 minutes. When both springs are replaced at the same time (which is the right approach. when one goes, the other isn't far behind), you restore proper balance and give the opener a clean start.

Yes. Springs on a double garage door come in pairs, and they wear at roughly the same rate. If one has snapped, the other has experienced the same number of cycles and is under similar stress. Replacing both at once costs more upfront but saves you from a second service call within months. and prevents the uneven wear that happens when one new spring is paired with one near-end-of-life spring.
For homes with heavier doors. solid wood doors or older steel models common in many Wolfeboro properties. upgrading to high-cycle springs (rated for 25,000 cycles or more) is worth considering. The upfront cost is higher, but the extended lifespan often makes it the better long-term value.
A professional spring replacement should include more than just swapping the springs. A thorough job involves inspecting the cables (which take stress when a spring fails), checking roller and track condition, testing door balance after installation, and lubricating all moving parts. The door should be tested through multiple cycles before the technician leaves.
If you've been putting off addressing a door that's been slow, noisy, or uneven, a spring service visit is also a good time to catch other issues early. Check out our complete list of services to see what a full tune-up covers, or get in touch to schedule a visit.
Q: My garage door opened fine this morning but won't open tonight. Could it be the spring?
A: Yes, and this is actually the most common scenario. Springs often fail during the first use after a period of rest. particularly in cold weather when the metal is at its most brittle. Disconnect the opener and try lifting the door manually. If it's extremely heavy or won't budge, a spring has likely broken. Don't continue using the opener in this state.
Q: How much does spring replacement typically cost?
A: Costs vary based on door size, spring type, and whether you're replacing one or both springs. Standard torsion spring replacement generally runs a few hundred dollars for parts and labor. High-cycle springs cost more upfront but last significantly longer. Getting a written estimate before work begins is always the right approach.
Q: Can I still open my garage door manually with a broken spring?
A: Technically yes, but the door will feel very heavy. potentially 150 to 300 pounds of dead weight with no spring assist. If you need to open the door in an emergency, it can be done carefully with another person helping, but do not use the automatic opener until the spring is replaced. Repeated use of the opener with a broken spring will damage or destroy the opener motor.
