Why Garage Door Springs Fail in Northwood Winters (And How to Stay Ahead of It)
2026-03-16 7 min read
If you've lived in Northwood for more than one winter, you already know how punishing the cold gets. Temperatures regularly drop into the teens. sometimes below zero. and the swings between a cold morning and a slightly warmer afternoon happen over and over from November through March. Your garage door springs feel every one of those cycles, and by late winter, many of them are ready to give out.
This isn't a scare tactic. It's just physics, and it's something Northwood Garage Doors sees play out every single year across town and in neighboring communities like Epsom and Chichester.
What's Actually Happening to Your Springs in the Cold
Torsion springs. the large coiled springs mounted above your garage door. are made of tightly wound high-strength steel. Steel behaves predictably in warm weather, but once temperatures drop toward freezing, the metal contracts and becomes less flexible. As a result, the spring gets slightly shorter and tighter, which means there's more internal tension before you've even touched the door opener.
When you hit that button on a frigid January morning, you're asking a spring that's already under extra stress to do its job of lifting a door that can weigh 150 to 300 pounds. For a spring that's still in good shape, it handles it fine. For one that's been cycling for seven or more years, that added cold-weather tension can be the final push it needs to snap.
Beyond the pure cold, there's a second problem: freeze-thaw cycling. Northwood's winters don't stay at one temperature. they bounce. A morning at 12°F becomes an afternoon at 38°F, then drops again overnight. Each swing forces the metal in your springs to expand and contract. After dozens of these cycles across a full winter season, microscopic fatigue builds up in the steel coils. The spring hasn't grown weaker from one cold snap; it's been weakening incrementally with every freeze-thaw cycle since fall.
Warning Signs You Shouldn't Ignore
Springs rarely go from fine to broken without any notice. The trouble is that most homeowners don't know what to listen or look for. Here are the signs that your springs are struggling:
- The door feels unusually heavy when you lift it manually. This is one of the clearest indicators that spring tension is failing. - Jerky or uneven movement as the door opens. especially if one side rises faster than the other. - Squeaking, popping, or creaking sounds during operation. These sounds indicate metal stress that shouldn't be brushed off. - Visible gaps in the spring coil above the door. A gap means the spring has already snapped and the door should not be operated. - The opener strains or hums louder than usual, especially on cold mornings. Your opener is telling you it's working much harder than it should be.

What You Can Do. and What You Shouldn't
There are a few things homeowners can safely do to reduce stress on aging springs during cold weather. Keeping the springs lightly lubricated with a proper garage door lubricant (not WD-40) helps reduce friction and slows wear. It's worth noting that in cold conditions, standard lubricants can thicken and become less effective. use a lithium or silicone-based product rated for cold temperatures.
You can also help by keeping your garage a few degrees above freezing. If your garage is attached to your home, even modest weatherstripping improvements and an insulated door can make a real difference. For more on that, see our post on preparing your garage door for the colder months.
What you should not do is attempt to adjust or replace the springs yourself. This is not a gray area. Garage door springs store enormous amounts of energy under tension. If a spring snaps or uncoils unexpectedly during a DIY repair attempt, the result can be severe injury or significant property damage. Spring work is a job for a trained technician with the right tools. full stop.
How Long Do Springs Actually Last?
Most standard torsion springs are rated for around 10,000 cycles. one cycle being one full open and one full close. If your household uses the garage door four times a day, that works out to roughly seven years of lifespan. Some springs are rated for 20,000 or even 30,000 cycles and are worth the upgrade if you're already replacing them.
If you've lived in your home for more than seven years and haven't had the springs replaced, it's worth having them inspected before next winter. not after one fails on a cold morning in February.
Don't Wait for the Loud Bang
The most common way homeowners in the Northwood area discover a broken spring is a sudden loud bang from the garage. often while the door is closed and not in use. The door then either won't open at all or drops faster than it should, which creates a safety hazard.
Scheduling a spring inspection or tune-up before that happens is always cheaper and less stressful than an emergency call.

Frequently Asked Questions
How do I know if my garage door spring is broken?
The clearest signs are a door that won't open or feels extremely heavy to lift manually, a visible gap in the coiled spring above the door, or a loud bang you heard from the garage. If any of these apply, stop using the door and call a professional.
Can I still use my garage door if I think the spring is worn but not broken yet?
It depends on how worn it is. A door with a weakened spring puts extra strain on your garage door opener motor and cables, and can accelerate wear on other components. If the door is moving unevenly or the opener is straining, it's best to have it looked at before it becomes a bigger problem.
Is it worth upgrading to high-cycle springs when I replace them?
In most cases, yes. High-cycle springs. rated for 20,000 or more cycles. cost a bit more upfront but last significantly longer and are a smart investment if you use your garage regularly. It's a good example of where spending a little more now saves more later, something we cover in more detail in our post on long-term cost decisions for homeowners.
