Here's what most homeowners don't realize about garage door springs: they're doing 99% of the lifting work, not your opener. Your motor just guides the door. Those coiled metal rods above your garage are under enormous tension, and when they fail, you're looking at a door that won't budge and a repair bill you didn't budget for. After 15 years installing and replacing springs across Salem and southern New Hampshire, I've seen the same shock on homeowners' faces when I explain the cost and urgency.
There are two main types of garage door springs: torsion springs and extension springs. Torsion springs sit horizontally above your door and twist to lift it. Extension springs run along the sides of the door frame and stretch as it opens. Most residential doors in Salem use torsion springs because they're more durable and smoother. Extension springs are cheaper upfront but wear out faster and create jerky motion.
The type you have determines replacement cost, labor time, and how soon you'll need service again. If you're unsure which yours is, don't try to peek. A snapped spring under tension can cause serious injury. That's not me being dramatic. That's me being honest after watching too many DIY attempts go wrong.
Garage door springs last 7 to 9 years under normal use, not 10 or 12 like some folks assume. They cycle open and close roughly 10,000 times per year if you use your garage daily. That's 70,000 to 90,000 cycles before failure. Cold weather, humidity swings, and salt air from winter roads in New Hampshire accelerate rust and metal fatigue. One snapped spring means the other is usually close behind.
I've replaced springs in January more times than any other month. Salem winters stress metal springs harder than any other season. If yours are original to your home and you bought it more than seven years ago, replace them now before one fails and leaves you trapped inside or outside your own garage.

Spring replacement cost depends on spring type, your door's weight, and whether one or both springs need replacement. A single torsion spring replacement runs $200 to $400 in parts and labor for most Salem homes. Both springs together are usually $350 to $600. Extension springs are cheaper, around $150 to $250 per spring.
That price includes the spring itself, labor, and a safety inspection. Don't hire anyone who quotes you a spring alone without mentioning labor and inspection. Improper installation creates safety hazards and shortens the life of your new springs. If you want an exact estimate for your door, schedule a free quote and we'll assess your springs on site.

A door that opens slowly or unevenly is the first red flag. If one side of your door rises faster than the other, a spring is likely weakening. A loud bang or crack sound when opening or closing usually means a spring just snapped. Some homeowners hear a metallic twang and think it's minor. It's not. Get it checked same day.
Another warning sign: your opener working overtime or making grinding noise. The motor strains harder when springs are weak because it's doing more of the lifting. That extra strain on the opener reduces its lifespan and can cost you a replacement sooner than expected. See our guide on garage door openers in Salem, NH to understand how springs and openers work together.
I understand the temptation to save money. Springs are expensive and you're handy. But springs are compressed and under 200 to 400 pounds of tension depending on your door. If a bolt slips, the spring can unwind violently and cause fractures, lacerations, or worse. Professional tools and safety brackets aren't optional. They're mandatory.
We stock the right springs for Salem homes and install them with proper torque specs and safety checks. It's not just about replacing a part. It's about making sure your door operates safely for years. Visit our services page to see what spring replacement includes, then contact us to get a same-day estimate if your door is already failing.
If your door won't open, is stuck halfway, or you heard a loud snap, don't wait until business hours. A snapped spring is an emergency. Call 19789568293 and ask about our same-day availability. Most Salem appointments can be scheduled within 24 hours, and emergency calls often come in sooner.
Preventive maintenance saves money. If your springs are over six years old, have them inspected this fall before winter hits. A small investment in inspection beats the cost of an emergency call and rushed replacement in January.
How long do garage door springs last? Most springs last 7 to 9 years under normal residential use, cycling roughly 10,000 times per year. Harsh weather, salt air, and daily use can shorten that lifespan. Have yours inspected every two years after year five.
Can I replace one spring or do I need both? If one snapped, the other is likely weakening and will fail soon after. Replacing both at the same time costs only slightly more than one and prevents a second service call in weeks.
Why is spring replacement so expensive? Labor is the bulk of the cost because it's dangerous, requires specialized tools, and takes skill to install correctly. The spring itself is $50 to $150, but the expertise and safety measures make up the rest.
How do I know if my door has torsion or extension springs? Torsion springs sit horizontally above the door. Extension springs run vertically along the sides of the frame. When in doubt, don't look closely. Call a technician to identify and assess them safely.
What happens if I ignore a snapped spring? Your door becomes a safety hazard and your opener can burn out trying to lift the full weight alone. You'll be locked out or in, and the repair bill grows with each failed attempt to operate the door.
