Garage Door Springs in Sandwich, NH: Why Your Spring Snapped and What to Budget
7 min read
A customer called last Tuesday saying her garage door wouldn't budge. Her torsion spring had snapped overnight. Within an hour, she learned the repair would run $300 to $450, parts and labor included. That's far less than the $1,200 she feared paying. Garage door springs in Sandwich fail predictably, and knowing what's ahead saves money and stress.
Understanding Your Two Spring Types
Most residential garage doors use one of two systems: torsion or extension springs. Torsion springs sit above the door, connected to a shaft that turns when the door opens or closes. Extension springs run along the tracks on either side. Both carry the weight of your door. A typical residential door weighs 300 to 400 pounds, and springs handle this all day, every day, for seven to nine years on average.
Torsion springs are more common in newer homes and last longer. They balance load more evenly and fail less dramatically. Extension springs are cheaper upfront but wear out faster and can snap with more force. If your door suddenly drops or feels heavy, a snapped spring is usually the culprit.
What Causes Springs to Snap
Garage door springs fail due to fatigue, not sudden impact. Metal fatigues after thousands of cycles. A typical family cycles their door three to five times daily. Over seven years, that's 7,665 to 12,775 opening and closing motions. Springs lose flexibility with age, rust accelerates failure, and springs installed above humid garages corrode faster than those in dry environments.
Temperature swings in New England also matter. Sandwich winters cause metal to contract and become brittle. Spring failure often happens mid-winter when the metal is coldest and weakest. If you hear a loud bang from your garage, assume a spring snapped. Do not attempt to open the door manually.

Prevention and Budgeting Tips
Spring replacement isn't optional once they fail. However, you can extend their life with basic maintenance. Lubricate springs twice yearly with a light machine oil. Avoid heavy silicone spray, which attracts dirt. Keep the garage reasonably dry. Install a humidifier if your area stays damp.
If you own the home long-term, budget for spring replacement as routine maintenance, like roof shingles or water heater repairs. Springs last seven to nine years, so plan a replacement around year six or seven. Proactive replacement costs about the same as emergency repair but eliminates the crisis and keeps your door working smoothly.

When to Call Emergency Service
A snapped spring is inconvenient, not dangerous, assuming you don't force the door open. The garage door opener motor cannot lift the door without a functioning spring. Attempting to bypass the safety system risks injury and damage to the opener. Call us immediately for a repair estimate.
If your door is stuck closed and you need emergency access, that's a different conversation. We offer emergency garage door service throughout Sandwich. Learn when emergency service is actually worth it and what the cost looks like in our detailed guide.

Frequently Asked Questions
How do I know if my spring is about to fail?
Listen for creaking or squeaking sounds above the door. The garage door may feel heavier than usual during manual operation. Some springs show visible rust or thin sections before failure. These warning signs mean a spring replacement is coming soon, not today.
Can I replace a garage door spring myself?
No. Spring replacement requires specialized tools, safety knowledge, and experience. The tension stored in a spring can cause serious injury. Always hire a professional for this work. DIY repairs void your door's warranty and risk property damage.
How long does spring replacement take?
Most single-spring replacements finish within 60 to 90 minutes, including safety testing. If both springs need replacement or complications arise, allow two to three hours. We schedule same-day appointments when possible.
What's the difference between torsion and extension springs?
Torsion springs twist to lift the door and last longer (seven to nine years). Extension springs stretch along the tracks and typically last five to seven years. Torsion springs cost more but offer better balance and durability.
Do you offer warranties on replacement springs?
Yes. All springs installed by Sandwich Garage Doors include a five-year parts warranty. Some premium springs carry longer warranties. Ask about options when you call for your estimate.
