Garage Door Springs in Alstead, NH: When to Repair, Replace, or Call a Pro
2026-06-17 7 min read
If you've ever dealt with a stuck garage door, you know how frustrating it can be. Most of the time, a snapped or worn spring is the culprit. Garage door springs in Alstead handle the heavy lifting literally, and when they fail, your door stops working. Understanding what's happening behind that closed door helps you know when to call for help and what to expect in terms of cost and repair time.
How Garage Door Springs Actually Work
Your garage door weighs between 300 and 700 pounds depending on size and material. Springs counterbalance that weight so the opener motor doesn't have to lift the entire load by itself. Without springs, your garage door opener would burn out in weeks. See our guide on commercial garage doors in alstead: what you really need to know.
There are two main types: torsion springs and extension springs. Torsion springs sit above the door on a shaft and twist to store energy. Extension springs run along the sides of the door and stretch. Both do the same job, but they wear differently and cost different amounts to replace.
Torsion springs last roughly 7 to 9 years with normal use, handling about 10,000 to 20,000 cycles before fatigue sets in. Extension springs may wear out faster, especially in Alstead winters when cold temperatures make metal brittle. Read about preparing your garage door for winter: essential tips.
Signs Your Springs Need Attention Now
A snapped spring produces a loud bang or crack. You'll hear it. The door won't open at all, or it opens partway and stops dead. Don't try forcing it. The opener can't compensate for a broken spring, and forcing it will damage other parts.
Other warning signs include a door that opens unevenly, springs that look frayed or bent, or a slow, jerky opening motion. If you notice any of these, call for an estimate before the spring fully breaks.
We've written before about what your garage door noises really mean, and spring failure is often one of them.

Spring Repair vs. Replacement: The Cost Question
A single torsion spring costs between $150 and $300 in parts. Extension springs run $100 to $250 each. Labor adds another $100 to $200 depending on complexity. Most homeowners replace both springs at once, even if only one snapped, because the second one is usually close behind.
If only one spring is bad and the other is still good, you can replace just that one. But springs age together, and replacing just one creates an imbalance that puts extra stress on the remaining spring. Many technicians recommend replacing the pair to avoid a second emergency call next month.

Why Alstead Winters Hit Springs Hard
Cold weather accelerates spring failure. Metal contracts in freezing temperatures, making springs more brittle. A spring that might have lasted 8 or 9 years under mild conditions can snap at 6 years in a harsh New England winter. If your springs are past the 5-year mark heading into fall, have them inspected. It's cheaper to replace them on your schedule than to get stuck on a January morning.
We covered this in detail in our post on spring failure and winter preparation.
When to Call a Professional
Spring replacement is not a DIY job. Springs hold thousands of pounds of tension. A slip, mistake, or miscalibration can cause serious injury or property damage. Even experienced homeowners should hire trained technicians for this work.

Frequently Asked Questions
How do I know if my springs are about to fail? Look for rust, fraying, or visible gaps in the spring coils. Listen for creaking or popping sounds during opening. If the door feels heavier than usual or opens unevenly, springs are likely weakening.
Can I use my garage door if one spring is broken? No. A broken spring removes half the lifting force. The opener cannot safely lift the door, and attempting to do so damages the opener motor and can cause the door to fall unexpectedly.
How much does spring replacement cost near Alstead? A single spring replacement runs $250 to $500 in parts and labor. Replacing both springs typically costs $400 to $800 total, depending on spring type and local labor rates.
Why do springs break in winter? Cold metal becomes brittle and loses flexibility. Winter also means less lubrication, as grease thickens in cold. These factors combine to make spring failure more likely between November and March.
Do extension springs last longer than torsion springs? No. Both types last roughly the same number of cycles (7 to 10 years), but extension springs often wear unevenly and may fail sooner in homes with rough opening habits or poor maintenance.
