There's a reason spring failure is one of the most common garage door calls we get in late winter and early spring here in North Hampton. It's not bad luck. it's physics. The freeze-thaw cycles that define a New Hampshire winter put relentless stress on garage door springs from November through March, and by February many springs have quietly accumulated enough metal fatigue to be one cold morning away from snapping.
If you've ever walked out to your garage, pressed the opener button, heard a loud bang, and found the door won't budge. you already know how disruptive a broken spring can be. This post is about understanding why it happens and what you can actually do about it before you're stuck.
North Hampton sits squarely in a humid continental climate, with January temperatures that regularly struggle to stay above freezing and winters that bring snow from November through April. When overnight temperatures drop well below freezing and then climb back into the 30s and 40s during the day, the metal in your garage door springs expands and contracts with each cycle.
Think of it like bending a paperclip back and forth repeatedly. every individual flex is harmless, but the cumulative stress adds up until the metal gives. Your garage door springs experience the same incremental damage through every freeze-thaw cycle over the course of a New Hampshire winter. By late February or March, after months of this, many springs are operating on borrowed time.
This is also why so many emergency calls happen right as the season starts to turn. it's not that the weather suddenly gets worse, it's that the fatigue finally reaches a breaking point after months of buildup.
Most residential garage doors use one of two spring systems:
Torsion springs are mounted horizontally above the door opening on a metal shaft. They're the more common setup on heavier or double-wide doors and tend to be more durable overall.
Extension springs run along the sides of the door near the tracks. They're often found on older or lighter single-car doors.
Both systems are under significant tension and both are vulnerable to the same cold-weather fatigue. Most garage doors have two springs installed together, and when one breaks, the other is typically close behind. it's been under the same stress for the same number of years.
The good news is that springs rarely fail completely without showing some advance warning. Here's what to look for:
- Creaking, popping, or snapping sounds during operation. These indicate stress building within the coils and should be taken seriously, not ignored. - The door feels heavier than usual when you manually lift it. Your springs are what counterbalance the door's weight. a standard residential door weighs between 300 and 400 pounds. If the springs are losing tension, you'll feel it. - The door opens or closes at an angle, with one side visibly higher or lower than the other. This suggests uneven spring tension. - Slower-than-normal operation, where the opener motor seems to be working harder or the door takes noticeably longer to travel its full range. - Visible gaps in the spring coils or rust on the coil surface. Healthy springs show consistent, evenly spaced coils with no separation.
If you're seeing any of these, it's worth having a technician assess the system before you're dealing with an emergency. The difference between a scheduled replacement and an emergency call isn't just convenience. it's also cost.
When a torsion spring snaps, you'll usually hear a loud bang from the garage. it sounds like a gunshot to many homeowners. The door won't open, or will only rise a few inches before the opener strains and stops. In some cases, the door may drop unevenly or feel completely dead.
At that point, stop using the door. Forcing it with a broken spring puts serious stress on the opener motor, the cables, and the tracks. What started as a spring replacement can turn into a much larger repair job if the door is operated repeatedly in this state.
Spring replacement is not a DIY job under any circumstances. Garage door springs store enough tension to cause serious injury or death if mishandled. This is one of those situations where calling a professional isn't just the convenient choice. it's the safe one. The FAQ page has more detail on what to expect from a service call.
You don't need tools or technical knowledge to catch most warning signs early. A monthly visual check during the fall and winter months. October through March. takes about ten minutes and costs nothing.
With the door closed, look at the torsion spring above the opening. Are the coils evenly spaced, or do you see a gap somewhere? Any surface rust or flaking? Then stand back and operate the door a few times, listening for sounds that weren't there before.
For the balance test, disconnect the opener by pulling the red emergency cord, then manually lift the door to about waist height and let go. A properly balanced door should hold its position. If it drops to the floor or shoots upward, the springs are not carrying the load evenly. that's a call to make before the spring fails on its own terms.
Keeping your springs properly lubricated with a silicone-based spray or white lithium grease also reduces friction stress and meaningfully extends their lifespan. This is a quick add-on whenever you're doing your chain drive maintenance or any other seasonal upkeep.
In North Hampton and throughout the seacoast area. Portsmouth, Exeter, Stratham, Hampton. spring is the busiest season for garage door service calls. Technician availability tightens up fast once the weather breaks and homeowners start discovering winter damage all at once. Scheduling an inspection now, while things are quiet, gets you better availability and gives you options rather than urgency.
If you're already seeing warning signs or your door is behaving differently than it did last fall, reach out and get it looked at before a worn spring becomes a snapped one.
How long do garage door springs typically last in New Hampshire? Most standard springs are rated for somewhere between 10,000 and 15,000 cycles. If you use your garage door four times a day, that works out to roughly 7,10 years. NH's freeze-thaw winters and. for coastal homeowners. salt air exposure can reduce that lifespan meaningfully. Springs on older doors or doors that haven't been lubricated regularly tend to fail on the shorter end of that range.
Can I still use my garage door if one spring has broken? Technically the door may still move, but you shouldn't use it. Operating the door with a broken spring puts excessive strain on the opener motor, cables, and hardware. It's better to use a side entry door until the repair is made.
Should I replace both springs at the same time, or just the broken one? Replacing both is the right call in most cases. 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 months. putting you back in the same situation and paying for a second service call.
