Your garage door relies on one of two spring systems to lift that 300 to 400 pound door smoothly. Torsion springs sit above the door and twist to release energy, while extension springs run along the sides and stretch. Knowing which type you have matters because choosing the wrong replacement can cost hundreds extra and compromise safety.
Not all garage door springs in Epsom are created equal. The two main types serve the same job but work very differently, and mixing them up during repair is a common (and expensive) mistake homeowners make.
Torsion springs are mounted horizontally above your garage door opening. They store energy by twisting as the door closes, then unwind to help lift the door open. Most newer homes and heavier doors use torsion springs because they're more durable and safer. A torsion spring typically lasts 7 to 9 years with normal use.
Extension springs hang vertically on each side of the door frame and stretch as the door closes. They're common in older homes and lighter single-car doors. Extension springs don't last quite as long and require safety cables running through them. If one snaps, that cable prevents the spring from whipping across the garage.
Your door type and weight determine which system makes sense. A heavier wood or insulated door almost always needs torsion springs for reliable operation.
This is where budget matters. Torsion springs cost more upfront than extension springs, but they offer better value over time. A single torsion spring replacement typically runs 150 to 300 dollars, while extension springs cost 100 to 200 dollars per pair.
However, torsion springs last longer and are safer. If you replace an extension spring with a torsion spring to future-proof your door, expect a higher initial estimate. We've seen homeowners spend an extra 100 to 150 dollars upfront only to save money later by avoiding repeat repairs.
The real cost killer is waiting too long. A snapped spring means your door won't open, and ignoring the problem leads to motor strain and costlier repairs down the line. Many homeowners don't realize how much a delayed replacement costs until they need emergency service.

Before calling a technician, you can spot which system your door uses. Look above your garage door opening. If you see a tightly wound coil running horizontally across the top, that's a torsion spring. If you see two springs hanging vertically on either side of the frame, those are extension springs.
Never touch or attempt to adjust a spring yourself. Both types store enormous tension and can cause serious injury if mishandled. Even a small slip during diagnosis can result in a trip to the emergency room.
Most garage doors have two springs working together. When one snaps, the other can't support the door's weight alone. This happens more often in winter across New England because cold makes metal brittle. Our winter garage door spring guide explains why Epsom homeowners see more failures between November and March.
If one spring snaps, replace both at the same time. They wear at roughly the same rate, so the second one will likely fail within months if you only fix the broken one. This double replacement costs more upfront but prevents a second service call and keeps your door balanced and safe.

How long do garage door springs last? Torsion springs typically last 7 to 9 years under normal use, based on about 10,000 cycles per spring. Extension springs last slightly shorter. Lifespan depends on door weight, climate, and how often you use the door. Cold winters can reduce longevity by a year or two.
Can I replace just one spring? You should replace both springs at the same time, even if only one has snapped. Springs wear together and fail around the same period. Replacing just one leaves the other on borrowed time and creates an imbalanced door that strains the opener.
Which spring type is safer? Torsion springs are generally safer because they're enclosed above the door and less likely to whip if they break. Extension springs require safety cables to prevent injury if they snap. Both are dangerous to repair yourself; always hire a professional.
Why do springs cost different amounts? Torsion springs cost more because they're more complex to install, last longer, and support heavier doors. Extension springs are simpler but require more frequent replacement. Local labor rates in Epsom also affect the final bill.
Should I upgrade to torsion springs if I have extension springs? If your door is heavy or you want lower maintenance, upgrading to torsion springs makes sense. It costs more upfront but saves money over time. Ask for an estimate to see if the long-term savings justify the initial investment for your situation.
