Your garage door springs fail without warning. One day it opens fine; the next, it won't budge or crashes halfway down. A snapped spring is the culprit 90% of the time. Repair costs range from $200 to $400 per spring, but waiting until failure means paying emergency rates. This guide shows you how springs work, when they break, and how to avoid the worst-case scenario.
Your garage door weighs 300 to 500 pounds. Two springs (or sometimes one, depending on your system) support that entire load. They're under constant tension, storing energy when the door closes and releasing it when you open the door. Torsion springs sit above the door frame and twist to manage the weight. Extension springs run along the sides and stretch as the door lowers. Both types typically last 7 to 9 years with normal use, roughly 10,000 to 15,000 cycles. See our guide on garage door openers in derry: belt vs chain & why it matters to your budget.
The problem: springs are working every single day. Cold Derry winters and temperature swings make them brittle faster. When a spring finally snaps, the entire system collapses. Your door opener can't lift the weight alone, so the door either won't open or drops suddenly when closing.
Springs fail for three main reasons. First, wear and tear from constant cycling. Second, rust and corrosion from humidity and salt air. Third, poor maintenance or an undersized spring system installed initially. Read about commercial garage doors in derry: heavy-duty roll-up solutions for warehouses.
Winter months bring extra risk. Metal contracts in the cold, putting springs under additional stress. A spring that's already weakened will snap the moment you try to open your door on a freezing January morning. That's when you'll call for emergency service and pay 50% more than a standard repair.
You can catch a failing spring before it breaks. Listen for a loud bang or crack when operating your door. Look for visible gaps in the spring coil or unevenness when the door opens. If one spring is damaged, the other is likely close behind. Smart homeowners replace both springs at the same time, even if only one has failed.
Our seasonal maintenance guide covers the specific checks that catch spring problems early, saving you from an emergency visit.

Never attempt to repair or replace garage door springs yourself. The tension is extreme, and a slip can cause serious injury. A professional technician takes 30 to 60 minutes per spring.
Standard repair cost: $200 to $400 per spring, including labor and the part itself. A two-spring system runs $400 to $800 total. This is straightforward replacement of a broken spring. Emergency calls (nights, weekends, holidays) add $100 to $200 to that price.
If your springs are 8+ years old, consider full replacement even if one hasn't broken yet. You're already paying for a service call; replacing both springs at once costs only slightly more than a single replacement. You'll avoid a second emergency next year.
New garage door systems sometimes require different spring sizes or styles. When you're considering a full door replacement, springs factor into the overall estimate. Our installation cost guide breaks down how springs fit into the bigger picture.
Call a local company like Garage Door Derry near you, not a national chain. Local technicians understand Derry's weather patterns and typical spring failures. Ask for a free estimate before service. A reputable company will inspect both springs, explain their condition, and quote the work upfront.
Never accept vague pricing like "springs starting at $150." Ask what's included: labor, the actual spring part, and whether they're replacing one or both. Compare two estimates if possible.
Same-day service is common for spring repairs, but emergency rates apply after 5 PM or on weekends. If your door is stuck, that's a safety risk. Schedule a free quote during business hours and avoid the markup.
Regular lubrication and inspection add years to your springs. Once yearly, apply a light silicone spray to the spring coils. Clean debris from the tracks and rollers. These five-minute tasks cut rust risk significantly in New Hampshire's damp climate.

Snapped springs are frustrating, but they're also predictable. Springs don't last forever, and winter in Derry accelerates their decline. The best move is to catch them before failure and replace them on your schedule, not during an emergency.

How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years, or roughly 10,000 to 15,000 opening cycles. Maintenance, climate, and usage patterns affect actual lifespan. New England winters shorten spring life due to temperature stress.
Can I replace just one spring instead of both? Technically yes, but both springs wear at similar rates. Replacing one now means the other often fails within months. Replacing both together saves money on labor and prevents a second emergency call.
Why are spring repairs expensive? Springs sit under 300+ pounds of tension. Removal and installation require specialized tools and training. The risk of injury is high for untrained people, so labor costs are substantial. Parts themselves are $80 to $150 per spring.
How do I know if a spring is broken? A loud bang or crack, uneven door opening, sagging on one side, or a door that won't open at all point to spring failure. Have a professional inspect rather than guessing. Broken springs are dangerous to diagnose yourself.
What's the difference between torsion and extension springs? Torsion springs twist above the door frame and handle the load directly. Extension springs stretch along the sides. Most residential doors use torsion springs. The type determines replacement parts and labor but not overall cost much.
