Garage Door Springs Replacement: Cost & When to Replace in New Milford
2026-07-02 8 min read A2Z Garage Doors
A customer called last Tuesday afternoon. Her garage door wouldn't open, and she'd already spent two hours watching YouTube videos about torsion springs. "How much is this going to cost me?" she asked. The honest answer: $250 to $400 per spring for most New Milford homes, plus labor. But before you panic or grab a wrench, you need to know why springs fail, which type you have, and why calling a professional matters more than you think.
Understanding Your Garage Door Spring System
Garage doors use one of two spring types: torsion springs or extension springs. Torsion springs sit above your door and twist as the door opens and closes. Extension springs hang on either side and stretch like rubber bands. Both store massive amounts of energy, which is exactly why a snapped spring is dangerous to fix yourself.
Springs last roughly 7 to 9 years on average. That lifespan depends on usage, climate, and maintenance. New Milford winters are rough on springs because cold temperatures make metal brittle. If your door cycles 3 to 5 times daily, expect springs to wear faster than in less-used homes.
When a spring fails, your garage door opener can't lift the full weight of the door. You'll hear a loud bang or snap, see the door sag on one side, or find it won't open at all. Don't try to force it.
Spring Replacement Cost Breakdown
Most homeowners in New Milford pay between $200 and $400 per spring, depending on the type and quality. Here's what factors into the price:
Torsion springs typically cost $150 to $300 per spring (material). Extension springs run $50 to $150. Labor adds another $100 to $200 when you hire a professional.
Why the labor charge? Because replacing springs requires specialized tools, precise measurements, and knowledge of how to safely manage the tension. A professional carries liability insurance, too. If something goes wrong during DIY replacement, you're liable for injuries or property damage.
We've seen homeowners quote themselves $150 for parts, then spend twice that on emergency room visits. It's not worth it.

When to Replace Springs (Signs You Can't Ignore)
If your door is hard to open manually, even with the opener, springs are likely worn. A fully functional spring reduces the effective weight of your door to about 15 pounds. When springs fail, you're lifting 300 to 400 pounds by hand.
Listen for squeaking or creaking sounds. These suggest friction and wear. A slow, jerky opening is another red flag. Springs should allow smooth, even movement.
If one spring snaps, replace both. This isn't upselling. Springs wear together. The remaining spring will fail within months if you only replace one, and you'll pay for labor twice. We always recommend replacing the pair to keep your door balanced and your opener safe.

Why DIY Spring Replacement Is a Bad Idea
Torsion springs are under extreme tension. When you loosen the adjustment bolts, that energy can release violently. Fingers, hands, and faces have been seriously injured. Extension springs snap and can whip across the garage at dangerous speeds.
Professional technicians have specialized winding bars, safety equipment, and years of experience. They understand how to calculate the correct spring size for your specific door weight and dimensions. A wrong-sized spring won't lift your door properly and will fail faster.

Spring Maintenance Prevents Early Failure
Keeping springs in good shape extends their life. Lubricate springs annually with a light machine oil. Don't use WD-40; it's too thin. Wipe away dirt and debris.
Have your door professionally inspected every 2 years. Catching wear early means you replace springs on your schedule, not on an emergency basis at 9 p.m. on a Sunday.

Frequently Asked Questions
How long do garage door springs last? Most springs last 7 to 9 years with regular use. Cold winters, frequent cycling, and lack of maintenance can shorten that timeline. Lubricating springs annually and having them inspected every 2 years helps extend their lifespan.
Can I replace just one spring? Technically yes, but we don't recommend it. Springs wear together. Replacing only one leaves the other to fail within months, and you'll pay labor twice. Replacing both springs at once keeps your door balanced and saves money overall.
What's the difference between torsion and extension springs? Torsion springs twist above the door and handle heavier loads more reliably. Extension springs stretch on the sides and are cheaper upfront but less durable. Torsion is the modern standard for most residential doors.
Is it safe to open my garage door if one spring is broken? No. Don't open it manually or with the opener. A broken spring means the door's full weight rests on the opener motor, which can fail or cause the door to drop suddenly. Call a professional immediately.
Why do springs fail in winter? Cold makes metal brittle and reduces its flexibility. New Milford winters are especially hard on springs. Regular lubrication and inspection help springs survive the season better.
