If you've lived in Watertown long enough, you already know what a New England winter does to metal. Temperatures that swing from the low 20s in January up through the 80s in summer put every metal component on your home under real stress. and your garage door springs are no exception. For homeowners in neighborhoods like Coolidge Square, East Watertown, and the West End, a broken spring isn't a distant possibility. It's a when, not an if.
Understanding your springs now. before one snaps. can save you from an emergency call, a car stuck in the garage, and a bill that's two or three times higher than a planned repair.
Watertown sits in a humid continental climate with cold, snowy winters and warm summers. That temperature swing. sometimes 60 degrees or more between seasons. puts repetitive stress on the steel coils that hold your garage door up. Cold weather causes metal to contract and stiffen, and that physical stress accelerates the wear that happens with every single open and close cycle. As one Massachusetts technician puts it, freeze-thaw cycles and salty air make steel fatigue sooner, especially in older properties.
Much of Watertown's housing stock was built before World War II, which means a lot of garages in this city are running on spring systems that were never designed for decades of daily use in a New England climate. If your home in the Bemis neighborhood or near Watertown Square is on the older side, your spring setup deserves a closer look.
Before you can spot problems, it helps to know what you're looking at. There are two main spring types you'll find on residential doors:
Torsion springs mount horizontally above the door opening on a metal shaft. They twist to create the tension needed to lift the door and are generally considered more durable and smoother in operation.
Extension springs run along the sides of the door opening and stretch to provide lifting force. They're more common in older garage setups and tend to be more prone to imbalance if one spring fails before the other.
If you're not sure which type you have, check our services page. we work on both systems and can assess your setup during any service call.
Most homeowners don't notice spring wear until the door stops working entirely. But the signs show up earlier if you know what to look for:
Garage door springs are responsible for counterbalancing the weight of your door, making it easy to open and close. When they fail or weaken, the door's full weight. which can be 150 to 300 pounds. suddenly falls on the opener motor and on anyone trying to lift it manually.
If your opener seems to strain, hum, or quit halfway through lifting the door, it may be compensating for a broken or weak spring. This is hard on your opener motor and can cause it to burn out prematurely.
A spring breaking under tension can make a sharp, sudden noise. often compared to a gunshot. If you hear this while the door is closed and then find it won't open, a spring has almost certainly snapped.
Over time, springs corrode due to moisture and show visible signs of wear like rust, discoloration, or elongation. A rusty spring is more brittle and prone to snapping. Look for gaps in the coils of a torsion spring, or a stretched, misshapen appearance on extension springs.
A standard residential garage door should open in 12,15 seconds. If yours now takes noticeably longer, or if the door tilts or rises unevenly, the springs may no longer be doing their job equally on both sides.
Springs are rated by cycles. 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 that uses the garage door two to four times per day. High-cycle springs (rated for 25,000 to 50,000 cycles) last longer but cost more upfront.
For Watertown homeowners who use their garage as a primary entry point. which is common given the cold winters and the premium on parking in this part of Greater Boston. those 10,000 cycles can come around faster than you'd expect.
If you're unsure how old your springs are, that's worth figuring out. A simple balance test can help: disconnect the opener and manually lift the door to about waist height. If the springs are in good shape, the door should stay in place. If it falls or rises on its own, the spring tension is off and it's time for an inspection.
This is one home repair that belongs on the "call a professional" list. no exceptions. Springs are under extreme tension and store significant mechanical energy. When released improperly, they can cause serious injury. A 150 to 300-pound door can drop without warning if spring support fails mid-repair. Even experienced DIYers can miscalculate the correct spring weight rating for their specific door, which causes premature wear on the opener and the new spring.
Proper replacement requires matching the spring to the door's exact weight and panel style, then performing a balance test to confirm the job is done right. You can read more about how your opener and springs work together in our limit switch adjustment guide, which covers the full mechanical relationship between your opener settings and door movement.
A professional spring replacement in the Watertown area typically takes 60 to 90 minutes. A good technician will inspect not just the springs but also the cables, rollers, and opener settings. since all of that hardware was likely installed at the same time and wears at a similar rate.
When you're ready to schedule a repair or want a second opinion on your spring condition, reach out to our team.

We'd rather help you catch a problem early than get an emergency call on a cold Tuesday morning when your car is stuck inside.
Q: Can I still use my garage door if a spring is broken? A: No. Operating a garage door with a broken spring puts excessive strain on the opener motor and can damage cables, rollers, and other hardware. There's also a real safety risk. the door can drop suddenly without spring support. Stop using it and call for service.
Q: Should I replace both springs even if only one is broken? A: In most cases, yes. If both springs were installed at the same time, they've experienced the same amount of wear. Replacing only the broken one often means the second spring fails within a few months. Replacing both at once saves a second service call and keeps the door balanced.
Q: How do I know if my spring is torsion or extension? A: Look above the door. If you see a single horizontal spring (or two springs side by side) mounted on a bar above the door opening, those are torsion springs. If you see springs running along the horizontal tracks on the left and right sides of the door, those are extension springs.
