Garage Door Springs Cost & Estimate Guide for Plymouth, NH
2026-08-09 5 min read
Here's what most homeowners don't realize about garage door springs: a snapped spring doesn't just stop your door from opening. It can damage your opener, trap your car inside, and leave you vulnerable to weather or theft until you fix it. The cost varies wildly depending on whether you have a torsion spring or extension springs, but the real number you should care about is the estimate before the work starts.
After 15 years on service calls across Plymouth and the surrounding region, I've seen homeowners shocked by spring replacement bills they thought would be half the price. That shock is preventable. This guide breaks down what garage door springs actually cost, what affects the price, and how to get an honest estimate from someone who isn't trying to upsell you. See our guide on safety reversal testing: a complete guide for homeowners.
Understanding Your Spring Type Matters
Not all springs are created equal, and your door has one of two types. A torsion spring sits above your garage door and winds up to store energy. An extension spring runs along each side of the door and stretches. Torsion springs are more common in newer homes and last longer, typically 7 to 9 years with normal use. Extension springs wear out faster, often in 5 to 7 years.
Why does this matter for cost? Torsion springs run $150 to $300 per spring. Extension springs cost $100 to $200 each, but you usually need two. However, labor is where the real difference shows up. Torsion spring replacement requires specialized tools and takes longer, so labor runs $200 to $400. Extension spring work is simpler, often $150 to $300 in labor. A full torsion spring replacement in Plymouth typically lands between $400 and $700 total. Extension springs usually cost $350 to $600 for both springs and labor combined.

What Drives the Price Up or Down
Your door size matters. A heavy 18-foot commercial door needs heavier duty springs than a standard residential 16-footer. Door weight directly impacts spring cost. Rust or corrosion on your hardware adds time and sometimes requires new brackets or cables, pushing the bill higher. If the snapped spring took out your cable or damaged your pulley system, you're looking at additional repairs beyond the spring itself.
Location and accessibility affect labor too. A garage in a tight residential neighborhood might take longer to work on than a straightforward driveway setup. Winter weather in Plymouth can actually slow us down as well. Cold makes metal stiffer and more prone to breaking during installation, and icy conditions mean extra setup time for safety.
One factor homeowners often overlook: getting a same-day estimate costs nothing. A technician can inspect both springs, the cables, the pulleys, and your opener in 20 minutes and give you a solid price before any work happens. That beats calling three different shops and wasting a week waiting for quotes.
When to Replace Both Springs, Not Just One
Here's a mistake I see constantly. One spring snaps, and the homeowner tells me to replace just that one. I usually push back. If one spring is dead, the other is likely close behind. Springs wear at the same rate because they handle the same load every single day. Replacing both at once costs maybe $150 to $200 more than replacing one, but it saves you a second service call and another full labor charge in six months.
If your door is more than 5 years old and you're dealing with a snapped spring, budget for both. Your next service call won't happen as soon. This is one area where spending a little extra upfront actually saves money long term.
Getting Your Estimate and Avoiding Surprises
Call Plymouth Garage Doors or any local shop and ask for a free estimate. Don't accept a price over the phone without an inspection. Springs vary by load rating, and a technician needs to see your setup in person. When the tech shows up, ask them to walk through what they found. A good estimate explains the spring type, the labor involved, any additional repairs needed, and the timeline.
