If your garage door moves slowly, hangs unevenly, or won't open at all, a broken spring is likely the culprit. Torsion and extension springs are the two main types that power your door, and understanding which one you have matters for repair costs and safety. Here's what you need to know about garage door springs in Dovergaragemasters, including why they fail and what repairs actually cost.
Your garage door weighs between 300 and 500 pounds. Springs counterbalance that weight, making it easy to open and close. Without them, the opener motor would burn out trying to lift dead weight.
Torsion springs sit on a shaft above your door. They twist and unwind to raise and lower the panel. Extension springs hang vertically on each side of the opening and stretch as the door goes down. Both types use stored mechanical energy. When that energy is exhausted, the spring snaps or loses tension, and your door stops working.
Springs typically last 7 to 9 years with normal use. Extreme heat, cold, and constant opening/closing can shorten that lifespan significantly.
Most residential garage doors use torsion springs. They're mounted horizontally above the door opening on a wound steel shaft. One or two springs balance the load depending on door size and weight.
Torsion springs are quieter, more durable, and distribute force evenly across the door. They cost more to replace than extension springs, but they last longer and rarely cause safety hazards if they fail. When a torsion spring snaps, your door simply stops moving. You won't have a sudden drop or flying cable.
A single torsion spring replacement in Dover typically runs $200 to $400 per spring, plus labor. If both springs need replacement (common with older doors), budget $400 to $800 total for parts, then add service charges for installation.
Extension springs run along each side of the door opening, parallel to the horizontal track. They stretch downward as the door closes and contract as it opens. Most older homes in Dovergaragemasters use extension springs.
The trade-off: they cost less upfront but present a safety risk if they snap. A broken extension spring can cause the door to drop suddenly or allow the cable to whip around. That's why safety cables exist. They run through the center of each spring to contain it if failure occurs.
Extension spring repairs cost $150 to $300 per spring, making them cheaper than torsion replacements. However, if one snaps, the second is usually close behind, so replacing both at once makes sense financially and practically.

Springs don't just wear out randomly. Several factors accelerate failure:
Rust and corrosion eat away at spring metal, especially in humid climates or near salt water. Massachusetts winters create conditions perfect for rust. Lack of lubrication increases friction and stress on the coils. Overuse from constant opening and closing wears springs faster. Impact or shock from slamming the door or hitting an obstruction can cause immediate failure.
One preventive step: lubricate your springs and hinges twice yearly with a silicone-based garage door lubricant. This simple maintenance extends spring life by 1 to 2 years.
If you suspect a snapped spring, do not attempt to open the door manually or operate the opener. A broken spring means the door's weight is no longer balanced, and you risk serious injury. Call a professional instead. We offer same-day estimates and can often repair the problem the same day you call.
We've covered specific pricing, but what drives the final bill? Several factors matter:
The type and size of your door. Heavy commercial doors or oversized residential doors need stronger springs, which cost more. The number of springs involved. Some doors have one, others two. Your location within the Dover area. Service calls to remote locations may include travel fees. Whether you need both springs replaced at once. Replacing a single snapped spring leaves the other aging spring vulnerable to failure within months. Most professionals recommend replacing both.

Spring repair is not a DIY job. Springs hold enormous tension. Releasing that tension incorrectly can cause serious injury or death. Even experienced homeowners should leave this to trained technicians with proper tools and safety equipment.

How do I know if my spring is broken? Your door won't open, closes slowly, or hangs unevenly on one side. You may hear a loud snap or bang from above the door. Never force the door open. Call a professional immediately for safety.
Can I open my garage door if the spring is broken? No. The door's weight is no longer balanced, and operating the opener risks motor burnout or personal injury. Wait for professional help.
How much does spring replacement cost near me? Torsion springs run $200 to $400 per spring plus labor. Extension springs cost $150 to $300 per spring. Final cost depends on door size, type, and whether you replace one or both springs.
How long do garage door springs last? Most springs last 7 to 9 years with normal residential use. Heavy use, extreme weather, and poor maintenance shorten lifespan. Regular lubrication extends durability significantly.
Should I replace both springs even if only one is broken? Yes. The second spring is nearly as old and stressed. Replacing both prevents a second failure within weeks and saves on service call fees.
