Garage Door Spring Replacement in New Hampshire
Fast torsion and extension spring replacement. Springs are matched to door weight and cycle count — we upgrade most homeowners to 30,000-cycle springs for 3× the typical lifespan.
Garage Door Spring Replacement is one part of our garage door repair coverage in New Hampshire. For the full picture — symptoms, costs, and when to repair vs. replace — start with the complete Garage Door Repair guide, or browse every garage door repair service we offer.
Spring replacement is the most common high-stakes garage door repair and the one we strongly recommend professional service for. The torque stored in a wound torsion spring can release a winding bar at velocities that send it across a garage; the cost of a professional spring replacement is a fraction of the cost of an ER visit. We replace torsion and extension springs in a single visit, with springs sized by measured door weight rather than guessed by appearance.
The default upgrade we offer is from builder-grade 10,000-cycle springs to 30,000-cycle high-cycle springs. The price difference is small — usually $40-$60 — and the lifespan triples, which means a typical homeowner replaces springs once during the door's life instead of three times. We back 30,000-cycle springs with a lifetime warranty for the original homeowner.
Every spring replacement includes a balance test, opener force/travel calibration to match the new spring tension, a cable and drum inspection (cables wear at a similar rate to springs and often need replacement at the same time), and a quick photo-eye verification. The complete service is one flat-rate visit with no hidden add-ons.
Signs you need garage door spring replacement
Visible coil gap or break
A snapped torsion spring shows a clear 2-inch gap between coils where the spring separated. Extension springs that have failed often hang slack.
Door won't open with the remote
Modern openers refuse to lift a door without spring assistance — the motor would burn out. Spring failure is the most common cause of 'opener won't lift the door'.
With the opener disconnected, a balanced door should lift with one hand. If you need both hands and full effort, the spring tension is wrong.
Door drops fast and slams
When you let the door go partway up and it crashes down, the counter-weight system has failed. Stop using the door — manual operation is unsafe.
Door 7+ years old, never replaced springs
Builder springs hit 10,000-cycle end-of-life around 7–10 years of typical use. Replacing proactively avoids the crack-of-dawn emergency call.
Common causes & what we fix
Cycle fatigue
Springs are rated by cycle count, not years. The clock starts at install and runs every time the door cycles. End-of-life is a predictable event.
Under-sizing at original install
Builders frequently spec the cheapest spring that meets minimum requirements. Under-sized springs run at higher stress per cycle and fail earlier than rated.
Coastal corrosion
Salt-air pitting weakens spring wire from the outside in. Uncoated springs in coastal zones can fail at 60% of their cycle rating.
Single-spring on a heavy door
Builders sometimes use a single torsion spring on doors that should run dual-spring. Single-spring on a heavy door fails roughly twice as fast.
Lack of lubrication
Torsion springs need a light annual lubrication to prevent inter-coil friction wear. Dry springs fail noticeably faster than maintained ones.

Frequently asked about garage door spring replacement
Top questions homeowners searching for Garage Door Spring Replacement near me ask us:
Should I replace one spring or both?
On dual-spring systems, replace both. The second spring is statistically days or weeks from failing — replacing both at once costs less than two separate visits and re-balances the system properly.
What's the lifespan of a 30,000-cycle spring?
For a typical household at 3 cycles/day, roughly 27 years. Heavy use households still get 12–15 years. The cycle count, not calendar time, governs lifespan.
Can I do this myself?
We strongly discourage it. The energy stored in a wound torsion spring is genuinely dangerous. Our service price is competitive with the cost of buying the correct tools and parts to do it once.
How long does spring replacement take?
Single-spring: 45–60 minutes. Dual-spring or 30,000-cycle upgrade: 60–90 minutes. Add 15–20 minutes if cables also need replacement (common).
What's the coverage?
5 years on standard springs, lifetime for the original homeowner on 30,000-cycle springs. 10-year workmanship guarantee on the install itself.
