Garage Door Springs in Londonderry: When to Repair vs. Replace
2026-08-15 7 min read A2Z Garage Doors
If a snapped garage door spring has left your door stuck and immobile, you need a repair, not a replacement of the entire system. Springs wear out from use and age, typically lasting 7 to 9 years depending on cycle frequency and climate. The good news: a spring repair is far cheaper than replacing the whole door, and we can often handle it same day.
What Are Garage Door Springs and Why Do They Break?
Garage door springs come in two main types: torsion springs and extension springs. Torsion springs sit above the door opening and twist to lift the weight of the door itself. Extension springs run along the side cables and stretch to create lifting force. Both types support roughly 400 pounds of door weight, so when one fails, the entire door becomes immobile.
Springs break because of metal fatigue. Every time your door opens and closes, the spring cycles. After 7 to 9 years of normal use, the metal loses its ability to flex without cracking. Winter weather in Londonderry and nearby towns accelerates this wear, especially if you don't keep tracks lubricated or aligned. A snapped spring usually makes a loud bang when it fails, and the door will feel heavy when you try to open it manually.
Repair vs. Replace: The Honest Answer
Here's the straightforward truth: if your spring snapped, repair it. Replacing the entire garage door makes sense only if the door itself is damaged, rusted beyond cosmetic fixes, or over 20 years old.
A spring repair typically costs $200 to $400 per spring, depending on the type and whether you need torsion or extension springs installed. If both springs failed (common in older systems), expect to budget for two repairs. For details on what that investment actually covers, check our garage door spring repair cost guide for honest pricing.

Why DIY Spring Replacement Is Dangerous
You might think fixing a garage door spring yourself saves money. It doesn't, and it puts you at real risk. Springs are under extreme tension. A torsion spring can unwind with enough force to break bones or cause serious lacerations. Extension springs snap with the speed of a whip. Even experienced mechanics use specialized tools and safety cables when working on springs.
Londonderry homeowners who've tried this often call us afterward to fix injuries and botched installations. Let a licensed technician handle it. We use proper equipment and carry liability insurance so you're protected.
Signs Your Springs Need Attention Now
A sagging door that opens unevenly suggests one spring is already failing. Grinding or squeaking noises mean the springs need lubrication, though if you hear a loud crack or bang, the spring has already snapped. If your door won't open at all and feels impossibly heavy when you try to lift it manually, a snapped spring is the culprit.
Don't ignore these signs. A broken spring forces your garage door opener to work twice as hard, shortening its lifespan and risking complete failure. See our emergency service page for what to do if your door is stuck, and call us for a same-day assessment.
Getting an Accurate Estimate Near Me
When you call for a garage door springs estimate in Londonderry, a technician needs to inspect the door in person. We'll identify which spring failed, check the condition of the other spring (even if it's still working), and assess the rest of the system. Torsion springs usually cost slightly more than extension springs, but both are straightforward repairs when you work with someone who knows the job.

How to Extend the Life of Your Springs
Regular maintenance prevents premature spring failure. Lubricate the springs and tracks every six months with a silicone-based garage door lubricant. Keep the tracks clean and aligned so the door doesn't bind or work harder than it should. If you notice the door opening slower than usual, that's a sign springs are weakening.

Frequently Asked Questions
How long do garage door springs last in Londonderry? Most springs last 7 to 9 years with normal use. Factors like humidity, temperature swings, and cycle frequency affect lifespan. If you use your door frequently or live in areas with big seasonal temperature changes, expect springs to wear faster.
What does a snapped spring cost to fix? A single spring repair runs $200 to $400 depending on whether it's torsion or extension. If both springs need replacement (recommended for balanced operation), budget $400 to $800 total. Labor and parts are included.
Can I drive my car if one spring is broken? No. A snapped spring prevents the door from opening safely. Never force it. Call for same-day service right away to avoid damaging the opener or pinching something in the mechanism.
Is it better to replace both springs even if only one broke? Yes, usually. If one spring has reached end of life, the other is likely close behind. Replacing both at once saves you a second service call in a few weeks and ensures balanced door operation.
How do I know if my springs need lubrication instead of replacement? Squeaking or grinding sounds mean lubrication is needed. If you hear a loud bang or crack, the spring has snapped and needs replacement, not lubricant. A visual inspection shows rust or visible cracks.
