Why Madbury Winters Are So Hard on Garage Door Springs (And What to Do About It)
2026-03-30 7 min read
If you've ever walked out to your garage on a cold February morning, pressed the opener button, and heard nothing but a loud bang. you already know what a broken spring sounds like. It's one of the most common calls we get here in Madbury, and it almost always happens in the dead of winter or right at the tail end of it. That's not a coincidence.
What Madbury's Climate Does to Your Springs
Madbury sits in a tough spot weather-wise. Winters here are genuinely freezing. January highs barely scrape above 31°F, and overnight lows regularly dip into the teens. Add in the fact that snowfall runs from October through April, and you've got a long, grinding cold season that puts real mechanical stress on your garage door system.
The issue isn't just the cold itself. It's the freeze-thaw cycle. Temperatures in Madbury fluctuate constantly. a cold night followed by an afternoon warm enough to melt snow, then a hard freeze again overnight. Each one of those cycles forces your torsion springs to expand and contract. Over and over, all winter long.
Torsion springs are already under enormous tension just doing their job. they're essentially storing and releasing energy every time your door moves. When cold steel becomes more brittle and less elastic, and when microscopic stress fractures from repeated expansion and contraction accumulate in the coils, you end up with a spring that's structurally compromised long before it shows any visible signs of failure.
By the time February or March rolls around, those springs have endured months of cumulative stress. What worked fine in November is now on borrowed time.
Warning Signs You Shouldn't Ignore
Springs don't always fail without warning. Here's what to watch for:
The Door Feels Heavier Than Usual
If your opener sounds like it's straining, or the door feels heavy when you lift it manually, that's a sign the spring tension has weakened. A properly balanced door should stay in place when you disconnect the opener and lift it halfway.
Uneven Opening
If one side of the door rises faster than the other, or the door tilts as it goes up, you likely have an imbalance. one spring is failing faster than its partner.
A Visible Gap in the Spring
With the door closed, look up at the torsion bar above the door. If you see a clear separation in the coil. a gap where the spring has separated. that spring is done. Don't use the door.
Squeaking or Grinding on Cold Mornings
Some noise is normal, but a persistent squeak or grinding sound that gets worse in cold weather often indicates the spring is under abnormal stress. This is your early warning.
What You Can Actually Do
You can't stop metal fatigue entirely, but you can slow it down and avoid getting caught off guard.
Lubricate your springs every fall. Use a silicone-based or lithium-grease spray. not WD-40. and coat the coils lightly before the cold sets in. A good lubricant helps prevent the metal from becoming brittle and reduces the rust that moisture-heavy winters can cause. Our neighbors in Dover and Durham deal with the same conditions, and this one step makes a real difference in spring longevity.
Test your door's balance in late fall. Disconnect your opener, lift the door to waist height, and let go. It should stay put. If it drops or shoots up, call a technician to adjust the spring tension before winter hits.
Know your spring's age. Standard builder-grade torsion springs are typically rated for around 10,000 cycles. For a household using the garage as the main entry point multiple times a day, that can translate to roughly 7,10 years. If your springs are approaching that range and you're heading into another New Hampshire winter, it's worth a proactive inspection.

Why You Should Never DIY a Spring Replacement
This point is non-negotiable. Torsion springs operate under extreme tension. enough to cause serious injury or worse if mishandled. Replacing them requires specialized winding bars, knowledge of proper tension calibration, and experience. It is not a YouTube project. If your spring has broken or you suspect it's near failure, stop using the door and call a professional.
Madbury Garage Doors handles spring replacements throughout Madbury and the surrounding towns. If you're not sure what condition your springs are in, a quick inspection is always worth it. especially coming out of a winter like this one.

Frequently Asked Questions
Q: How do I know if my garage door spring is broken? A: The most obvious sign is a loud bang followed by a door that won't open, or opens only a few inches. You may also notice a visible gap in the torsion spring coil above the door, or the door will feel extremely heavy when lifted manually.
Q: Can I use my garage door with a broken spring? A: No. Operating the door with a broken spring puts enormous strain on your opener motor and cables, and can cause additional damage or injury. Disconnect the opener and leave the door closed until a technician can replace the spring.
Q: How long do garage door springs last in a New Hampshire climate? A: Standard springs are rated for about 10,000 cycles, which typically means 7,10 years under normal use. In a cold climate with significant freeze-thaw cycling like Madbury's, springs on the lower end of that range. especially those that haven't been lubricated or inspected regularly. may fail sooner.
