A customer called last Tuesday saying her garage door wouldn't close. She'd heard a loud *bang* from the garage the night before but didn't think much of it. Turns out, a torsion spring had snapped. She asked the obvious question: "Why did this happen? I thought springs lasted longer." The honest answer: they do, usually 7 to 9 years, but several factors can cut that window short.
Garage door springs carry enormous tension. A typical residential door weighs 300 to 400 pounds. Those springs counterbalance that weight so your opener doesn't burn out after six months. There are two main types: torsion springs (mounted horizontally above the door) and extension springs (running along the sides). Both fail eventually. Both can be dangerous if you try to replace them yourself.
The lifespan question matters because a snapped spring means your door won't budge. Your car's trapped. Your home's security is compromised. You'll need professional help, and fast.
Springs wear out through regular use. Every open and close cycle stresses the metal. Humidity in the Franklin area accelerates rust and corrosion, especially on older springs without proper coating. Temperature swings (we can drop 30 degrees overnight in winter) cause metal expansion and contraction, weakening the material over time.
Lack of lubrication is another culprit. When springs aren't maintained, friction increases. The metal fatigues faster. A spring that should last eight years might fail in five.
Poor installation matters too. If a technician uses the wrong gauge or misaligns the spring, premature failure follows. This is why choosing a trusted local operator, not a chain box store, protects your investment.

Replacing a snapped spring costs between $200 and $400 for most residential doors. That's far cheaper than ignoring the problem. An unsupported door puts stress on your opener, which can then fail, driving repair costs to $500 or more.
Our blog post on emergency garage door repair costs in Franklin details what happens when you wait too long. The price jumps when secondary damage occurs.
If your springs are approaching seven years old and you live in a humid climate, consider preventive replacement. It costs less than emergency calls at 11 p.m. on a Saturday.
Regular lubrication with garage door spring oil (not WD-40) reduces friction and rust. Do this twice a year, spring and fall. A well-maintained torsion spring can sometimes stretch toward the nine-year mark.
Visual inspection helps too. Look for rust spots, gaps, or unevenness. If one spring looks damaged while the other appears fine, replace both. Springs wear at similar rates. Replacing just one creates an imbalance that stresses your opener and the door itself.
Our garage door maintenance guide covers these checks in detail. Spending 15 minutes twice yearly prevents expensive surprises.

Mountain humidity and temperature swings hit springs harder than flat regions. Springs in Asheville or Boone fail a bit faster than springs in lower elevations. The corrosive environment accelerates wear.
If your door is from 2017 or earlier, and you've never had the springs serviced, they're due. The cost of a routine replacement is nothing compared to a snapped spring that leaves you stranded.
Get ahead of failure. Call us for an inspection. Most homeowners find peace of mind worth the phone call alone.
Don't attempt spring replacement yourself. The stored energy in a torsion spring can cause serious injury. Don't ignore warning signs either. A door that moves unevenly, makes creaking sounds, or feels heavier than usual signals spring fatigue.

Springs don't last forever. But with the right care and timely replacement, you can avoid the stress and cost of emergency repairs.
How long do garage door springs typically last? Most springs last 7 to 9 years with regular use and maintenance. Climate, lubrication frequency, and installation quality affect lifespan. Franklin's humidity can shorten this window.
Can I replace just one spring if the other is fine? No. Springs wear at similar rates and share the load equally. Replacing one creates imbalance, stressing the opener and door. Always replace both torsion springs together.
What does a snapped spring sound like? A loud, sudden bang or crack, like a gunshot. This happens when tension releases all at once. The door won't operate afterward. Call a professional immediately.
Is spring replacement covered by homeowners insurance? Rarely. Most policies classify spring failure as normal wear and tear or maintenance, not damage. Check your policy, but assume you'll pay out of pocket.
How much does spring replacement cost near me? Residential spring replacement in Franklin typically costs $200 to $400 per pair, plus labor. Get a free estimate from us to know your exact cost based on your door type.
