Why Franklin NH Winters Are So Hard on Garage Door Springs (And What to Do About It)
2026-03-29 7 min read
If you've ever walked into your garage on a cold Franklin morning and found the door refusing to budge. or worse, heard a sharp bang from the garage overnight. there's a good chance a spring gave out. It's not random bad luck. There's a very real reason garage door springs fail more often here than in warmer parts of the country, and it has everything to do with the way New Hampshire winters work.
What Franklin's Climate Does to Garage Door Springs
Franklin sits in Merrimack County with a humid continental climate, and the winters here are genuinely harsh. Temperatures regularly drop into the low teens in January, and the freeze-thaw cycle starts as early as October and can drag into May. That constant back-and-forth. cold nights, slightly warmer afternoons, cold again. is exactly what breaks garage door springs down over time.
Here's the mechanics of it: torsion springs are made of tightly wound steel, and steel contracts when it gets cold and expands when it warms up. Every single temperature swing puts the metal through a small but real expansion-and-contraction cycle. Over hundreds of cycles across a winter, microscopic cracks begin forming in the coil. The spring hasn't necessarily aged out. it's been fatigued by the weather itself.
Make this worse: Franklin also deals with high humidity year-round, with average relative humidity running around 85% in January and February. Moisture accelerates corrosion on bare steel springs, weakening them further. By the time late winter rolls around and the temperature swings become the most dramatic. cold mornings, warmer afternoons. springs that have been quietly degrading since November are often right on the edge.
Homeowners in nearby Northfield and Tilton deal with the same conditions, and we see the same pattern: the most spring failures happen in late February and March, not during the coldest days of December. By that point in the season, the cumulative damage has already been building for months.
Warning Signs Your Springs Are in Trouble
Springs rarely snap without giving you some hints first. Here's what to pay attention to:
- The door feels unusually heavy when you try to lift it manually. Springs are what counterbalance the weight of the door. a 200-pound door shouldn't feel like 200 pounds when the springs are working right. - Jerky or uneven movement when the door opens. one side rising faster than the other is a common sign that one spring is weaker than the other. - Squeaking, creaking, or popping sounds during operation. These sounds mean the metal is under stress. - A visible gap in the spring coil. if you can see a separation in the tightly wound coil above the door, that spring is already broken. - The opener is straining or humming louder than usual. When springs lose tension, the motor has to work harder to compensate.
If you're seeing any of these signs, don't ignore them. A broken spring on a heavy garage door is a safety issue, not just an inconvenience. You can learn more about related hardware failures in our complete guide to cable repair, since cables and springs often wear out around the same time on older doors.
What You Can Do. And What You Shouldn't
There are a few things homeowners can reasonably do to extend spring life:
Lubricate annually, but do it right. Apply a lithium-based or silicone-based garage door lubricant to the spring coils before winter. This slows corrosion and keeps the metal from drying out. Avoid WD-40. it's a solvent, not a lubricant, and it evaporates quickly. Never use oil-based lubricants in freezing temps; they thicken and actually add friction.
Keep the garage a few degrees above freezing if possible. Even a small amount of heat from an attached house or a simple electric heater helps maintain the metal's flexibility and reduces the severity of overnight contraction.
Do a visual check twice a year. once before winter and once after it ends. Look for rust buildup on the coils, any visible gaps, and uneven tension (one spring sitting slightly lower or differently shaped than the other).
What you should NOT do: attempt to replace or adjust springs yourself. Torsion springs store an enormous amount of energy under tension. A spring that releases unexpectedly during DIY repairs can cause serious injury. This is one of those jobs where calling a professional isn't just a convenience. it's genuinely the safe call.

When to Replace Before They Break
Most standard garage door springs are rated for around 10,000 cycles (one cycle = one full open and close). If your garage door opens and closes four times a day on average, that's roughly 1,460 cycles per year. meaning a standard spring might last 6 to 7 years under normal conditions. In Franklin's climate, with the added stress of freeze-thaw cycles and humidity, that lifespan can be shorter.
If your springs are approaching that age range, it's worth talking to a technician about high-cycle springs, which are typically rated for 25,000 to 50,000 cycles. The upfront cost is higher, but you won't be dealing with emergency replacements every few winters. It's the same logic as budgeting for any home maintenance. proactive beats reactive every time.
Garage Door Franklin recommends a spring inspection every fall as part of standard seasonal prep. If you missed that window this year, late winter or early spring is actually the second-best time. you'll catch any damage that built up over the season before it becomes a failure.
Frequently Asked Questions
Q: How do I know if my garage door spring is broken versus just worn? A: A broken spring usually has a visible gap in the coil and causes the door to feel extremely heavy or fail to open at all. A worn spring may still function but shows signs like uneven movement, louder-than-usual motor noise, or the door drifting slightly when stopped mid-travel. Both situations warrant a professional inspection. contact us to schedule one.
Q: Can I still use my garage door if a spring is broken? A: Technically the opener may still try to run, but operating a garage door with a broken spring puts excessive strain on the opener motor and cables, and can cause the door to drop unevenly. It's best to avoid using it until the spring is replaced.
Q: How long does a spring replacement take? A: A professional spring replacement on a standard residential door typically takes 1 to 2 hours. If both springs need replacing. which is often recommended even if only one has broken. the job is still usually completed in a single visit.
