Garage Door Springs in Lexington: Torsion vs. Extension (And Why It Matters)
2026-07-16 7 min read
Your garage door springs are the hardest working part of your system, yet most homeowners don't know what type they have until one snaps. Torsion and extension springs do the same job differently, and understanding the difference saves you money and headaches. Here's what you need to know about garage door springs in Lexington before you call for a repair.
Torsion Springs vs. Extension Springs: The Core Difference
Torsion springs wind tightly above your door and twist to lift it. Extension springs run along each side of the door and stretch as it opens. Most modern homes in Lexington use torsion springs because they're smoother, safer, and last longer (typically 7 to 9 years with normal use). Extension springs are cheaper upfront but wear faster and carry more safety risk if they break.
Your door weighs between 300 and 400 pounds. That weight is why springs exist. Without them, your garage door opener would burn out in months trying to lift dead weight.
Why Springs Snap (And When It Happens)
Garage door springs fail because they cycle constantly. A typical spring opens and closes your door 10,000 to 15,000 times over its lifespan. That's it. No mystery, no manufacturing defect most of the time. Cold weather speeds up failure. Massachusetts winters are rough on springs. Metal becomes brittle, and the constant freeze/thaw cycle weakens the coils faster.
If you hear a loud bang from your garage, that's usually a snapped spring. Don't try to use the door. You'll damage the opener and risk the door crashing down. This is a safety issue we take seriously at Garage Door Company Lexington. Read our guide on garage door safety in Lexington to understand the full picture.

The Cost Picture: What Honest Pricing Looks Like
A single torsion spring replacement runs $150 to $250 in parts and labor around Lexington. Extension springs are cheaper (usually $100 to $150 per spring), but most doors need both springs replaced at the same time. A snapped spring means the surviving spring is near the end of its life too.
We don't charge more because you're panicked. Our estimate is the same whether you call at 8 a.m. or 6 p.m. We've seen shops in the area mark up emergency calls by 40 percent or more. That's not how we work. Honest pricing means you know the cost before we touch anything.
Total cost for a typical two spring replacement: $300 to $400 installed. If someone quotes you $600 or more, get a second opinion. Our garage door cost and pricing guide covers what homeowners actually pay in this area.
When to Replace Both Springs (Even If Only One Broke)
This is where we save homeowners real money. If one spring breaks, we strongly recommend replacing both. Here's why: the surviving spring is already 7 to 9 years old. It will snap within months. You'll pay for another service call, another labor charge, and another trip to the garage.
Replacing both springs at once costs maybe $100 more than one. Compared to two separate service calls, you're ahead. We give you a clear estimate upfront so you can decide, not a sales pitch.
Signs Your Springs Need Attention Before They Snap
A garage door that's harder to open than normal. A door that closes unevenly or tilts to one side. Visible rust or corrosion on the springs. These are warning signs. Springs don't always snap without notice. Many fail gradually.
If you suspect spring trouble, don't wait. Schedule a free quote with us and we'll inspect them properly. Same-day diagnosis and repair are available most days.
Maintenance Extends Spring Life
Lubricate your springs once a year with a silicone-based garage door lubricant. Not WD-40 or household oil. Silicone. This reduces friction and slows the wear cycle. A $10 can of lubricant might add 6 to 12 months to your springs' lifespan.
Keep your garage dry. Humidity and salt air (especially if you're near the Route 128 corridor toward Waltham) accelerate rust. If you're running your door in extreme cold, let it warm up before heavy use.

When to Call a Professional
DIY spring replacement is not safe. Torsion springs are under extreme tension. A slip means serious injury or death. We've heard stories of people trying to save $200 and ending up in the emergency room. Don't be that person. Call us instead. Our full service menu includes spring replacement and inspection.
Your garage door springs deserve professional care. Lexington homeowners trust us because we price fairly and explain everything. One call gets you a clear answer.
Springs don't last forever, but they last long enough. When yours fail, you'll know where to turn.

Frequently Asked Questions
How long do garage door springs last? Torsion springs last 7 to 9 years with average use (10,000 to 15,000 cycles). Extension springs typically last 5 to 7 years. Cold climates and frequent use shorten lifespan. Regular lubrication helps extend it.
Can I replace just one spring? Technically yes, but we don't recommend it. If one spring breaks, the other is near end-of-life. Replacing both prevents a second failure in weeks. The cost difference is small; the inconvenience difference is huge.
What's the difference between torsion and extension springs? Torsion springs twist above the door and are safer, quieter, and longer-lasting. Extension springs stretch along the sides and are cheaper but wear faster and pose higher safety risk if they break. Most modern homes use torsion.
Is garage door spring replacement an emergency? Yes. A broken spring means your door won't open safely or smoothly. The opener may be damaged. Call for same-day service rather than trying to use the door. We answer emergency calls across Lexington.
How much does spring replacement cost in Lexington? A single torsion spring runs $150 to $250 installed. Two springs typically cost $300 to $400 total. Costs vary based on spring type and door weight. We provide a free estimate before any work begins.
