Garage Door Springs in Somerville: How They Work and When to Replace
2026-05-26 7 min read
Here's what most homeowners don't realize about garage door springs in Somerville: they're doing nearly all the heavy lifting. That 400-pound door? Springs carry the weight, not your opener. When one fails, your entire system fails with it. Understanding how they work and recognizing warning signs can save you from a sudden breakdown and an expensive emergency call.
How Garage Door Springs Actually Work
Your garage door has either torsion springs or extension springs. Torsion springs sit above the door and twist to create lifting force. Extension springs run along the sides and stretch like rubber bands. Both store massive amounts of energy, then release it to help your opener lift the door smoothly.
Springs are engineered to complete roughly 10,000 cycles. That's about 7 to 9 years of typical use. Some springs last longer; many fail sooner if they're overtaxed or poorly maintained. The springs don't get weaker gradually. They fail suddenly. One day your door works fine. The next, it's stuck or crashing down.
That's why knowing the difference between spring types matters. Torsion springs are safer to replace because the tension is more controlled. Extension springs can snap violently and become projectiles. If you hear a loud bang and your door stops moving, a snapped spring is almost always the cause.
Common Signs Your Springs Need Replacement
A garage door that opens halfway then stops is a classic sign. The opener can't lift the full weight anymore. You might hear a loud noise, metal squeaking, or a sharp crack. Sometimes the door feels unbalanced when opening or closing.
Don't ignore these warnings. A broken spring forces your opener to work much harder, which can burn it out prematurely. If you live in Somerville and your door has shown these signs, get a professional assessment for your garage door spring replacement needs. A technician can inspect both springs and recommend what needs fixing before something else breaks.

Why DIY Spring Replacement Is Risky
Springs are not a do-it-yourself job, even for confident homeowners. The tension is enormous. If a tool slips or you miscalculate, you could be seriously injured. Hospital visits from spring accidents happen regularly.
Professional technicians have the right tools, knowledge of local building codes, and insurance. They'll replace the springs correctly and make sure your door hangs evenly. They'll also check the opener, cables, and other components while they're at it. Schedule a free quote with Garage Door Company Somerville today to get a same-day estimate and skip the guesswork.
Spring Replacement Cost in Somerville
Spring replacement typically costs between $200 and $400 per spring, depending on the type and quality. If both springs need replacing (which is common), budget $400 to $800 total. This seems high until you consider the alternative: a snapped spring that damages your door, opener, or worse, injures someone.

Frequently Asked Questions
How long do garage door springs last? Most springs are rated for 7 to 9 years of normal use, or roughly 10,000 opening cycles. Heavy use, poor maintenance, or extreme temperature swings can shorten this. Regular inspection helps catch wear before failure.
Can I replace just one spring if only one is broken? Technically yes, but both springs typically wear at similar rates. Replacing just one can cause uneven door movement and put extra stress on the remaining spring. We usually recommend replacing both for balance and longevity.
What's the difference between torsion and extension springs? Torsion springs twist above the door and are safer to replace. Extension springs stretch along the sides and can snap violently. Your door type determines which you need. A technician can tell you in seconds.
How much does spring replacement cost near me? In Somerville, expect $200 to $400 per spring installed. Total cost for both springs ranges from $400 to $800. Exact pricing depends on spring size, quality, and your door's weight. Call for a free estimate.
Is a snapped spring an emergency? Yes. Stop using your door immediately. A broken spring forces the opener to carry full weight, which can damage it or cause the door to fall. Contact a professional right away.
