Garage door springs don't get much attention until they break. Then, suddenly, your door won't budge, your car is stuck inside, and you're searching for someone to come out same-day. It's one of the most common emergency calls in Waltham. and in almost every case, there were warning signs that showed up weeks or months earlier.
This post is about reading those signs early, understanding what you're actually dealing with, and knowing what to do next. For homeowners in Waltham's older neighborhoods. from the Victorian-era homes along the Charles River in Angleside to the ranches and colonials out in Cedarwood and Lakeview. garage door spring failures are more common than you might think, simply because many of these systems have been running for a decade or more.
Your garage door typically weighs between 150 and 300 pounds. The springs are what make it feel light. They counterbalance the door's weight, meaning your opener motor. and your arms, when you open it manually. only have to manage a fraction of that load. Without functioning springs, the door is essentially dead weight.
There are two main types:
- Torsion springs. mounted horizontally above the door opening on a metal shaft. More durable, found in most modern systems, and typically rated for 10,000,20,000 cycles. - Extension springs. run along the horizontal tracks on either side of the door. Common in older systems. If one breaks, the door can become severely uneven and cables may go slack.
One full open-and-close counts as one cycle. A household that uses their garage door four times a day will hit 10,000 cycles in roughly seven years.
This is one of the earliest and most telling signs. Disconnect your opener and try to lift the door manually to about waist height. A properly balanced door should stay in place with minimal effort. If it feels like you're lifting a car hood. or it drops when you let go. your springs are losing tension. At that point, your opener is compensating for the weight the springs are no longer carrying, which accelerates motor wear.
A garage door should open and close with some mechanical sound, but grinding, squeaking, or a loud bang are different matters entirely. A sudden sharp noise. often compared to a gunshot. usually means a torsion spring has snapped under full tension. If you hear that sound and your door stops working, that's exactly what happened. Stop using it immediately and get in touch with a professional.
Grinding or squeaking that persists after lubrication can also indicate that springs are dry, misaligned, or worn past their service life.
Take a look at your torsion spring above the door. A healthy spring has tightly wound, evenly spaced coils. If you can see a visible gap. a separation between coils where there shouldn't be one. the spring has broken. This is not something you can work around. A broken spring cannot support the door's weight and needs immediate replacement.
Also look for rust or discoloration on the coils. Rust makes metal brittle and prone to sudden failure, especially during the wet, humid winters common in Greater Boston. Waltham's consistent year-round precipitation accelerates this kind of corrosion on springs that haven't been regularly maintained.
Does one side of your door hang lower than the other, or does it tilt and shake as it opens? That's a strong indicator that one spring has failed while the other is still holding. The uneven strain also puts excess stress on your cables, tracks, and rollers. turning what started as a spring problem into a multi-component repair if left too long.
If your opener hums, hesitates, or stops mid-lift, it's likely being asked to do work the springs are supposed to handle. Openers are not designed to lift a door's full weight. Running an opener against a failing spring system shortens its lifespan significantly and can lead to motor burnout. an avoidable and more expensive repair.
For a broader look at what signals mean your system needs attention, see our post on recognizing when your garage door needs repair.
Most standard springs are rated for around 10,000 cycles, which typically translates to seven to ten years of average household use. High-cycle springs rated for 25,000,50,000 cycles are available and worth the upfront cost for busy households. If your springs are approaching or past the ten-year mark, they should be on your radar regardless of whether you've noticed problems yet. Proactive replacement is far less disruptive than an emergency failure.
This is worth saying clearly: garage door spring replacement is not a DIY job. Springs are under extreme tension. they store significant mechanical energy, and when that energy releases unexpectedly, the consequences are serious. Broken fingers, facial injuries, and worse have resulted from homeowners attempting this repair without the right tools and training. A garage door without spring support can weigh 150,300 pounds and drop without warning.
Leave spring work. and cable work. to trained technicians. Everything else on the maintenance side is fair game. You can safely lubricate hinges and rollers, swap weatherstripping, and clean your tracks. But for spring replacement, the cost of professional service is genuinely worth it.
If you're unsure what condition your springs are in, schedule an inspection before a small issue becomes an emergency. Garage Door Company Waltham serves homeowners throughout Waltham and the surrounding area. check our service areas page to confirm coverage near you.

Q: Can I still use my garage door if one spring is broken? A: You shouldn't. Operating a door with a broken spring puts excessive strain on your opener motor and the remaining spring (if you have two), and risks the door dropping suddenly. Disconnect the opener and avoid using the door until the spring is replaced.
Q: Should I replace both springs at the same time? A: Yes, almost always. If one spring has broken, the other has likely seen the same number of cycles and is at similar risk of failure. Replacing both at once saves you a second service call. and keeps your door balanced and safe.
Q: How do I know if I have torsion or extension springs? A: Look above the door. A single large coiled spring mounted horizontally on a shaft above the opening is a torsion spring. Two springs running along the overhead tracks on either side of the door are extension springs. If you're unsure, a technician can identify them quickly during any service visit.
