Garage door springs fail without warning, leaving your door stuck and your car trapped inside. The good news? Understanding which type you have.torsion or extension.plus knowing realistic replacement costs means you'll never overpay or delay a critical repair. Let's cut through the confusion.
Your garage door uses one of two spring systems, and they work differently.
Torsion springs sit horizontally above your door opening. They twist under tension, storing and releasing energy as the door moves up and down. Most residential doors in Brookline rely on torsion springs because they're durable, quiet, and balanced. A typical torsion spring lasts 7 to 9 years with normal use.that's roughly 10,000 to 15,000 cycles.
Extension springs run vertically along the sides of the door frame. They stretch and contract to lift the weight. You'll find these on older homes or lighter-duty installations. Extension springs wear faster and require safety cables to catch them if they snap, preventing the door from crashing down.
At Brookline Garage Doors, we inspect both types free of charge when you call for service.
Springs fail due to metal fatigue, not sudden damage. Tiny stress cracks develop over years, then one day.*snap*.the spring breaks while the door is opening or closing.
A snapped spring makes itself obvious: your door either won't open, opens partway then drops, or makes a loud bang followed by silence. You might hear a grinding or clicking sound. Don't try to force it. A broken spring puts strain on your opener motor and creates a safety hazard.
Stop using the door and contact our team for same-day service near you. We handle emergency calls across Brookline and neighboring Newton.

I'll be straight with you. Spring replacement isn't cheap, but it's essential. A single torsion spring runs $150 to $300 for the part, plus labor. Most doors need two springs (they work in pairs), so budget $400 to $700 total installed. Extension springs cost less.$100 to $200 per spring.but labor is similar.
These prices assume standard residential doors. High-cycle commercial doors or specialized applications cost more. We provide a written estimate before we touch anything. No surprises.
Why the range? Spring gauge (thickness), length, and your door's weight all factor in. A heavy 18-foot wood door needs heavier springs than a standard aluminum door. We measure on-site and quote accurately.
Read our guide on long-term cost benefits to understand how spring maintenance saves money versus ignoring the problem until your opener fails.
You don't replace springs based on a calendar. You replace them when they fail or show signs of wear.
Replace immediately if: - One spring has snapped, Both springs are leaking oil or rust, Your door is lopsided when closing, The door feels heavier than normal
Replace proactively if: - Springs are original to a 10+ year old door, You use your garage door 5+ times daily, You live in a coastal area (salt air corrodes springs faster)
Brookline's humid climate and freeze-thaw cycles accelerate spring wear. A spring that lasts 9 years elsewhere might last 7 here. That's why we recommend annual inspections, especially in fall.
I respect the DIY spirit, but garage door springs are the exception. A torsion spring under full tension holds 200+ pounds of force. If it slips during installation, it can cause serious injury or death. This isn't exaggeration.it's documented in safety reports.
Leave spring replacement to trained technicians. We're insured, licensed, and equipped. The cost difference between DIY disaster and professional service isn't worth the risk.
If your door is stuck, noisy, or you suspect spring trouble, call us at (617) 446-3026. We'll diagnose the issue, explain your options, and quote an honest price. Many Brookline homeowners are surprised how affordable a timely repair is compared to waiting until the opener burns out.
Spring problems don't resolve themselves. The sooner you act, the sooner your door works safely again.
How long do garage door springs last? Torsion springs typically last 7 to 9 years (roughly 10,000 cycles) with normal use. Extension springs wear faster, often 5 to 7 years. Frequency of use, climate, and maintenance affect lifespan.
Can I replace one spring if only one broke? Not recommended. Springs wear as pairs and fail around the same time. Replacing one leaves the other to fail soon after, causing imbalance and door damage. Replace both for safety and longevity.
How much does a garage door spring cost near me? Single torsion springs run $150,$300; extension springs cost $100,$200. Labor adds $200,$400. A full replacement (two springs, labor, parts) typically costs $400,$700 in the Brookline area.
Is a snapped spring dangerous? Yes. A broken spring removes support from the door, which can crash down unexpectedly. Never attempt to open a door with a snapped spring. Call a professional immediately for safe removal and replacement.
Do I need a permit to replace garage door springs? Not typically. Spring replacement is routine maintenance. However, if you're upgrading the door itself, check our guide on permits and regulations for Brookline's specific requirements.
