Garage door springs come in two main types: torsion springs (mounted above the door) and extension springs (on the sides). Torsion springs last 7 to 9 years under normal use, while extension springs typically wear faster. When a spring snaps, your door becomes difficult or impossible to open safely. The cost for replacement ranges from $200 to $400 per spring, depending on size and type.
Your garage door weighs between 300 and 600 pounds. Springs don't lift it directly; they balance that weight so the opener uses minimal force. Without functioning springs, your opener works overtime. A snapped spring puts dangerous strain on the motor and cables. It also creates a safety hazard because the door can fall unexpectedly.
Most homeowners don't think about springs until something breaks. That's understandable. But springs are the hardest-working component in your entire system. They cycle open and close thousands of times per year. Over time, metal fatigue sets in. Temperature swings in Lyndeborough winters accelerate wear because metal contracts and expands with cold snaps and thaws.
Torsion springs twist around a metal shaft above your door. They use rotational force to lift the weight. These are standard on most modern garage doors and are considered safer because they're enclosed and less likely to snap violently.
Extension springs stretch along the sides of your door frame. When the door opens, they extend; when it closes, they contract. If an extension spring breaks, the coil can snap across the garage, which is why they're considered riskier in homes with kids or pets.
Torsion springs cost slightly more to replace ($250 to $400 each), but they last longer and perform better. Extension springs run $150 to $250 per side. If you're unsure which type you have, take a photo and text it to us at (978) 953-8559 for a quick answer.

A snapped spring is obvious. The door won't open, or it opens partway then stops hard. You might hear a loud bang from the garage.
Less obvious signs include a door that opens slowly, feels heavier than normal, or closes faster on one side. These suggest springs are weakening and failure is near. Don't wait for a complete snap. A preemptive replacement costs less than emergency service and prevents damage to your opener.
If you've noticed your door acting up, our garage door tune-up service in Lyndeborough includes a full spring inspection. We'll tell you honestly whether replacement is needed now or can wait a few months.
Lyndeborough winters are brutal on metal. When temperatures drop to 10 degrees or below, springs become brittle. When they warm back up, stress fractures form. Over one season, a marginal spring can fail completely.
Why garage door springs snap in Lyndeborough winters explains this in detail. The short version: cold metal loses elasticity, and repeated freeze-thaw cycles create micro-cracks that eventually rupture. This is why we recommend having springs inspected every fall before winter sets in.
Salt air and humidity also accelerate rust on the spring coils themselves. Rust weakens the metal from the outside in. Regular maintenance helps, but once rust starts, replacement is the only real fix.
Here's where I'm straightforward. A spring replacement isn't cheap, but it's predictable. Most reputable shops charge between $200 and $400 per spring, including labor. Torsion springs (which most homes need) fall in the higher range because they're more complex to install.
Some companies charge inflated emergency fees. We don't. Same-day service costs the same whether you call at 9 a.m. or 6 p.m. See our garage door cost and pricing guide for more details on what fair pricing looks like across all repair types.
If both springs are original (typically 7 to 9 years old), replace both at once. One spring has already failed; the other will follow within months. Replacing one now and one later costs more in labor.
We serve Lyndeborough and surrounding areas. To get an accurate estimate, we need to know your door's size, spring type, and whether you have one or two springs. A quick inspection takes 15 minutes.

Garage door springs aren't glamorous. But they're essential. When yours fail, don't delay. The longer you wait, the more damage spreads to your opener and cables. Call (978) 953-8559 today to schedule a free quote and get your door working safely again.
How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years with normal use (roughly 10,000 to 20,000 cycles). Harsh winters, salty air, and high-use doors may wear springs faster. Regular maintenance extends life by a few months but can't prevent eventual failure.
Can I replace a garage door spring myself? Springs are under extreme tension and can cause serious injury if mishandled. We strongly recommend professional replacement. DIY attempts void warranties and create safety hazards. Call a licensed technician to handle spring work safely.
Why are both springs recommended for replacement? Springs wear at similar rates because they endure the same cycles. If one snaps, the other will fail soon after. Replacing both at once saves labor costs and prevents a second service call within weeks.
What's the difference between emergency and regular service pricing? Lyndeborough Garage Doors charges the same rate for same-day service as we do for scheduled appointments. No hidden emergency fees. Transparency matters more to us than squeezing extra profit from urgent repairs.
Do you offer financing for spring replacement? Yes. We work with homeowners on payment plans for larger repairs. Ask about options when you call (978) 953-8559 or get a quote online.
