A customer called last Tuesday morning. Her garage door wouldn't budge. One glance at the spring above the door told me everything: it had snapped overnight. She asked, "Why didn't I see this coming?" The honest answer is most homeowners don't know what garage door springs in Sharon actually do, or how to spot trouble before it becomes an emergency.
After 15 years on the trucks, I've learned that springs are the hardest working part of your entire system. They're also the most misunderstood. This guide walks you through the two main types, what maintenance actually prevents, and when you need to pick up the phone.
Your garage door weighs 300 to 400 pounds. Springs counterbalance that load, making it light enough for your opener to lift. There's no magic here, just physics and metal under constant tension.
Torsion springs sit on a horizontal rod above your door. They twist and unwind as the door moves. Most modern homes in Sharon use torsion springs because they last longer, run quieter, and handle weight more evenly. A quality torsion spring lasts 7 to 9 years with normal use.
Extension springs run along the sides of your door frame. They stretch and contract. Older homes often have extension springs. They're cheaper upfront but wear out faster, typically lasting 5 to 7 years. Extension springs also need safety cables to catch them if they snap.
Which do you have? Look up at your door from inside the garage. Springs above the door opening = torsion. Springs on the left and right sides = extension.
Springs fail because they're under stress every single day. Every time your door opens or closes, the spring cycles. A typical spring cycles 10,000 to 15,000 times before it gives out. That's roughly 10 years of daily use.
But stress isn't the only killer. Rust, dirt buildup, and lack of lubrication accelerate failure. In Sharon, winter salt and humidity create the perfect storm for corrosion. Springs that sit in damp garages fail faster than springs in dry ones.
Temperature swings matter too. Metal contracts in cold and expands in heat. Repeated cycles weaken the coil over time. If your garage isn't insulated, your springs work harder and fail sooner. (Learn more about this in our garage door insulation guide for Sharon homeowners.)
Real maintenance takes 30 minutes every few months. Here's what stops problems before they start:
Lubricate the springs. Use a silicone spray or garage door lubricant. Don't use WD-40 (it dries out). Spray the coils lightly. This reduces friction and slows rust.
Wipe away debris. Dust and dirt trap moisture. A dry cloth once a month keeps corrosion at bay.
Listen for noise. A squeaking spring means it needs lubrication. A grinding or creaking sound might signal a crack. Call early if something sounds off.
Check the door balance. Open the door manually about waist high, then let go. A balanced door should stay put. If it drifts down or up, the springs are losing strength.

A single snapped spring always requires replacement. You can't splice a spring back together safely. Springs work as a pair on torsion systems, so replacing one means replacing both. Yes, that costs more upfront. But it ensures even weight distribution and prevents the second spring from failing months later.
If your door is over 10 years old and one spring fails, replace both. If it's newer, replacing just the failed spring is acceptable, though uneven wear will eventually catch up. Our spring replacement cost guide breaks down pricing so you know what's fair.
Don't attempt spring repair yourself. Torsion springs carry enough stored energy to cause serious injury. Even releasing tension requires specialized tools and training. Call Sharon Garage Doors for a free estimate and let a professional handle it.
Regular tune-ups cost less than emergency replacements. We've written a full maintenance guide that stops expensive repairs before they happen. The basic idea: spend $100 or $200 now on preventive care, save $500 or $1,000 on emergency calls later.
Spring replacement isn't cheap. Depending on your spring type and door weight, expect $200 to $400 for labor and parts. But you can stretch that timeline by keeping springs clean, lubricated, and monitored.
If your door is slow to open, makes noise, or feels heavier than usual, springs may be weakening. Don't wait for a complete failure. Call us at (978) 346-3855 for a same-day inspection and honest quote. We serve Sharon and the surrounding area with fast, straightforward service.
Your springs work hard so your door doesn't. Give them the attention they deserve, and they'll keep your garage running smoothly for years to come.
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use. Extension springs wear faster, usually lasting 5 to 7 years. Lifespan depends on climate, humidity, maintenance frequency, and how often you use the door.
Can I replace a garage door spring myself? No. Springs carry dangerous stored tension that can cause serious injury or death if released improperly. Only trained technicians with specialized equipment should handle spring replacement. Always call a professional.
Why do springs cost so much to replace? Spring replacement requires specialized tools, precise installation, and safety expertise. Labor typically accounts for 60 percent of the cost. Both springs are replaced together on torsion systems to prevent imbalance and premature failure of the remaining spring.
How do I know if my spring is about to fail? Signs include loud squeaking or grinding noises, a door that feels heavier to operate, visible rust or cracks on the coil, or the door drifting down when held at mid-height. Call immediately if you notice any of these.
What's the difference between torsion and extension springs? Torsion springs twist above the door and last longer. Extension springs stretch on the sides and wear out faster. Torsion is standard in newer homes and preferred by most professionals because of durability and safety.
