Here's what most homeowners don't realize about garage door springs in Boscawen: they're doing nearly all the heavy lifting. Your opener doesn't lift the door. Those springs do. When one fails, your door becomes a 300 to 400 pound dead weight. That's why a snapped spring isn't just an inconvenience. It's a safety issue and a repair you can't ignore.
Your garage door relies on either torsion springs or extension springs to operate safely. Torsion springs sit above the door and twist to store and release energy. Extension springs run along the sides and stretch to help lift. Both types support the entire weight of your door while the opener simply guides it up and down.
Springs are engineered to cycle thousands of times. A typical spring lasts between 7 to 9 years with normal residential use, roughly 3 to 5 cycles per day. The moment one snaps, the other (if you have two) carries double load. That second spring fails faster. This is why we always recommend replacing both springs at the same time, even if only one has broken.
Before a spring snaps completely, you'll notice warning signs. The door becomes heavier to open manually. You hear a loud bang or crack. The door closes faster than normal or opens slowly. If you see visible gaps or separation where the spring attaches, stop using the door immediately.
Don't attempt a DIY repair. Springs are under extreme tension and can cause serious injury if mishandled. A professional can diagnose whether you need torsion replacement, extension repair, or a full system evaluation. If you're in Boscawen or nearby areas and notice these signs, contact us to schedule a free quote before the spring completely fails.

The cost of garage door spring replacement depends on several factors. Torsion springs typically cost more than extension springs because they're custom wound for your door's weight and size. A professional installation with both springs replaced usually ranges based on your specific door configuration and local labor rates.
When you call for an estimate, we'll ask about your door weight, age, and whether both springs need replacement. The price also reflects the difficulty of access and whether your system has additional safety components like cables or pulleys that need attention. For details on what affects your total repair bill, see our guide on what homeowners actually pay for garage door repairs.
Spring replacement qualifies as an emergency repair in most cases. If you're facing an unexpected failure, our team can often arrange same-day service. Compare this with other emergency scenarios in our breakdown of emergency repair costs.
The best way to extend spring life is regular maintenance. Lubrication, balance testing, and visual inspection catch wear before springs fail. A well maintained system keeps springs working the full 7 to 9 years. Neglected systems fail in 5 years or less.
Most homeowners skip this step until something breaks. Then they're surprised by the cost. A little preventive care now prevents expensive emergency calls later. Our maintenance tune-up guide walks through what actually needs attention each season.
Replacing garage door springs requires specialized tools, knowledge of proper tension, and safety equipment. A technician measures your door weight, calculates the correct spring size, and winds or installs springs to exact specifications. Incorrect tension either leaves your door feeling heavy or causes it to rise too fast and slam at the top.
We've seen DIY attempts that cost homeowners more in the long run due to improper installation or additional damage. Call our services page to learn more about our spring replacement process, or reach out to get a same-day estimate.
How long do garage door springs last? Residential springs typically last 7 to 9 years with normal use (3 to 5 cycles daily). Lifespan depends on spring quality, door weight, and maintenance. Commercial doors with heavy use see shorter lifespans.
Can I replace just one spring? You can, but both springs share the load. Replacing only the broken one causes the remaining spring to fail sooner. Most professionals recommend replacing both springs at the same time for safety and longevity.
What's the difference between torsion and extension springs? Torsion springs twist above the door and are custom sized for each door. Extension springs run along the sides and stretch. Torsion springs are stronger and last longer but cost more to replace.
How much does spring replacement cost? Pricing varies by spring type, door size, and whether one or both springs need replacement. Labor and material together typically reflect your door's specific requirements. Contact us for a free estimate.
Is a snapped spring an emergency? Yes. A broken spring leaves your door inoperable and unsafe. The remaining spring (if you have two) is overloaded and will fail rapidly. Stop using the door and call a professional immediately.
