If you walked into your garage this morning and heard a loud bang. or found your door suddenly won't budge. there's a good chance you've got a broken spring. It's one of the most common garage door failures we see across Stoneham and surrounding towns like Medford and Malden, and it tends to catch homeowners completely off guard.
Here's what you actually need to know: the symptoms, the costs, and why you should never attempt this repair yourself.
Your garage door. whether it's on a classic Cape Cod in Haywardville, a Colonial on Nobility Hill, or one of the newer builds near Bear Hill. weighs anywhere from 130 to over 300 pounds. Springs do the heavy lifting. They store tension as the door closes and release it to help lift the door open. Without functioning springs, your opener motor is essentially trying to deadlift a car. and it will burn out trying.
There are two main types:
- Torsion springs. mounted horizontally above the garage door opening, wound tightly around a metal bar. These are the standard on most modern sectional doors in Stoneham. - Extension springs. run alongside the overhead tracks and stretch when the door closes. Older homes, including Stoneham's stock of early 1900s single-family houses, sometimes still have these.
If you're not sure which type you have, look above your door when it's closed. A thick coiled spring across the top is torsion. Springs running along the sides of the tracks are extension.
Springs don't usually snap without warning. Learn to catch the early signs before you end up stranded:
Disconnect your opener and try lifting the door manually. A balanced door should feel like roughly 10,15 pounds. light enough to hold in place with one hand. If it feels like you're lifting a refrigerator, the springs are losing tension.
Raise the door halfway and let go. It should stay put. If it drifts down, the springs can no longer counterbalance the door's weight properly.
Healthy torsion spring coils sit tightly together. A visible gap. sometimes an inch or more. means the spring has snapped. Stop using the door immediately.
Many Stoneham homeowners describe it as sounding like a gunshot inside the garage. That's a broken torsion spring releasing its stored tension all at once. Don't keep running the opener. you risk burning out the motor and damaging the door panels.
If your opener sounds like it's struggling, or the door reverses partway up, the motor is working against dead weight it was never designed to handle alone.
In the greater Boston metro. which includes Stoneham and nearby communities. spring replacement typically runs $175,$375 for a single door, and $300,$450 for a two-car door, depending on spring type and the complexity of your setup. Torsion springs generally cost more than extension springs, but they're more durable and safer.
One thing worth knowing: not all springs are equal. Budget springs are rated for around 5,000,10,000 cycles. A premium high-cycle spring can be rated for 25,000,50,000 cycles. potentially lasting 15,20 years even with daily use. The price difference upfront is modest, but skipping one or two full replacement jobs over your door's lifetime adds up.
Also factor in: if one spring fails, both are typically the same age and under the same wear. Replacing just the broken one and leaving the other is asking for a second service call within months. Most reputable technicians will recommend replacing both at the same time. and they're right to do so.
We're not saying this to drum up business. Garage door springs store an enormous amount of tension. enough to cause serious injury or death if mishandled. Professional technicians use calibrated winding bars, proper safety equipment, and years of hands-on experience to replace springs safely. The tools alone aren't something you'll find at a hardware store, and online tutorials skip over a lot of the ways this job goes wrong.
If you're curious about what else you can do to extend the life of your springs between professional visits, this maintenance guide for homeowners covers lubrication, balance tests, and seasonal checkups in detail.
A quality spring replacement should take 45,90 minutes from start to finish. The technician should:
- Inspect the full door system, not just the broken spring, Replace both springs (on a double-torsion system) - Check and lubricate cables, drums, and rollers, Test door balance before leaving, Provide a written warranty on parts and labor
If a company quotes you over the phone without knowing your door size, spring type, or wire gauge. be skeptical. A legitimate quote requires seeing your setup.
Stoneham's climate runs from sub-freezing winters (lows near 21°F are common) to humid summers. That temperature swing stresses springs over time, and the winter cold in particular makes metal more brittle. Homes closer to Spot Pond and the Middlesex Fells also deal with higher ambient moisture, which accelerates rust on uncoated springs. If your springs are more than seven years old and you haven't had them inspected, this spring (pun intended) is a good time to have someone take a look.

Q: Can I still open my garage door if a spring is broken? Technically yes. but you shouldn't. Running the opener with a broken spring puts enormous strain on the motor and can burn it out. If you need to get your car out, disengage the opener and lift the door manually with help from another person. It will be very heavy.
Q: How long do garage door springs last in Stoneham? Standard springs are rated for roughly 10,000 cycles. For a typical Stoneham household using the garage door 3,4 times a day, that's about 7,10 years. High-cycle springs can last 15,20 years. Cold winters and humidity can shorten lifespans, especially on uncoated or poorly lubricated springs.
Q: Should I replace both springs even if only one is broken? Yes, almost always. Both springs age together and are under the same wear. If one snapped, the other is close behind. Replacing both during one visit saves you the cost of a second service call. and keeps your door balanced in the meantime.
