Garage Door Springs in Stratham, NH: When to Repair vs. Replace
2026-09-10 7 min read
A customer called last Tuesday with a garage door that wouldn't budge. His torsion spring had snapped that morning. The first question everyone asks: do I need to replace the whole thing, or can you just fix it? The answer depends on age, damage type, and whether the other spring is close behind.
Understanding Your Spring Type
Garage doors use two main spring systems: torsion and extension. Torsion springs sit above the door opening and twist to lift the weight. Extension springs run along the tracks on either side and stretch to assist the lift. Most residential doors in Stratham use torsion springs because they last longer and handle weight more evenly.
A snapped spring isn't a judgment call. It's broken. The door won't open, and neither spring can safely support 300 to 500 pounds of door weight. Attempting a workaround puts you at injury risk.
Repair vs. Replace: The Real Breakdown
You can't truly "repair" a snapped spring. Once a torsion or extension spring breaks, it loses all tension and structural integrity. What you can do is replace that single spring.
Here's where cost matters. If one spring failed, the second spring is likely near the end of its lifespan too. Springs last 7 to 9 years under normal use. If your door is older than six years and one spring just snapped, replacing both springs at the same time prevents a second breakdown weeks later. This approach saves money and inconvenience in the long run.
We've seen homeowners skip the second spring replacement to save $100 or $150 upfront, then call us back three months later when the remaining spring finally gave out. That's two service visits instead of one. Learn more about typical spring lifespan and what drives replacement decisions.

Single vs. Dual Spring Replacement
If your door is newer (under five years old) and only one spring snapped due to a manufacturing defect, replacing just that spring might make sense. Get an estimate first. A professional inspection can tell you whether the second spring shows wear patterns that signal imminent failure.
The cost difference between one and two springs is smaller than you might think. Labor makes up most of the bill. A technician must decompress the system, remove the broken spring, wind the new one, and test everything. Adding a second spring means minimal extra time.

When Damage Goes Beyond Springs
Sometimes a snapped spring causes secondary damage. If the door dropped suddenly, the track might be bent. The door panels could have shifted. The opener might need adjustment. A free estimate will reveal these issues before you decide to proceed.
This is why we always recommend a full inspection when a spring fails. Treating only the spring and ignoring a bent track sets you up for opener strain and future failures. Safety matters most here.

Frequently Asked Questions
Q: Can I drive my car out if my garage door spring is broken? A: No. A broken spring means the door won't open safely, and the opener alone cannot lift the full weight. Do not force it; you risk damaging the opener and injuring yourself.
Q: How much does spring replacement cost in Stratham? A: A single torsion spring replacement ranges from $200 to $350, including labor. Two springs typically run $350 to $500. Read our full pricing guide for context on what drives cost.
Q: Should I replace both springs if only one snapped? A: If your door is over six years old, yes. Both springs wear at the same rate, so the second is likely failing soon. Replacing both at once saves a second service call.
Q: How long does spring replacement take? A: Most jobs take 1 to 2 hours. Same-day service is available in Stratham. Call 19785416990 to check availability.
Q: What causes a spring to snap? A: Metal fatigue from repeated cycles (open/close). Poor maintenance, rust, and extreme temperature swings accelerate wear. Regular lubrication and inspection extend spring life by 2 to 3 years.
