In our years serving Lexington, we've seen this problem again and again: a homeowner hears a loud bang from the garage, the door won't open, and panic sets in. A snapped garage door spring usually means you're facing an unexpected repair bill. The good news? Understanding what's broken, why springs fail, and what replacement actually costs can save you hundreds of dollars and help you make smart decisions fast.
Your garage door weighs 300 to 400 pounds. You don't notice this when it opens smoothly because springs do the heavy lifting. Most residential doors use one of two types: torsion springs (mounted above the door, on a rod) or extension springs (mounted on each side, running along the horizontal tracks).
Torsion springs are the most common in modern homes. They twist to store and release energy as the door moves. Extension springs stretch and contract. Both types are under enormous tension. Over time, metal fatigues. Springs typically last 7 to 9 years with normal use, roughly 10,000 to 15,000 cycles. When a spring snaps, the door becomes immovable and potentially unsafe.
Temperature swings in Massachusetts winters accelerate wear. Cold makes metal brittle; repeated freeze-thaw cycles stress the coils. If you haven't replaced springs in a decade, now is the time to stop waiting.
A loud bang or popping sound when opening or closing is the classic warning. You might also notice the door moving slower than usual, jerking unevenly, or refusing to open at all even with the opener running. Sometimes a single spring fails first; the door tilts or feels unbalanced.
Never try to force a door with a broken spring. The opener can't compensate for the lost support, and you risk damaging the motor or the door itself. For more on recognizing problems early, check out our guide to 5 warning signs your garage door needs professional repair.
Spring replacement cost depends on the type, quality, and whether one or both springs need replacing.
Torsion springs typically run 150 to 300 dollars per spring plus labor. Most single-spring jobs cost 300 to 500 dollars total. If both springs are old, replacing both at once (usually recommended to avoid a second failure soon after) runs 400 to 700 dollars.
Extension springs are cheaper per spring (50 to 150 dollars each) but labor is often higher because both must be replaced together for balance. Expect 200 to 400 dollars total.
Labor usually accounts for half the cost. A technician must safely remove the old spring, install the new one, adjust tension, and test the door. This is not a DIY job for most people. The tension is dangerous, and improper installation can injure you or damage the door.

Preventive maintenance can extend spring life and catch problems before failure. Regular inspection and lubrication reduce friction and stress. If you haven't had your door tuned up recently, garage door maintenance in Lexington pays for itself by catching wear early.
Call a local garage door company and ask for a free estimate. A reputable technician will inspect both springs, check the door balance, and explain what needs replacing and why. Don't assume one broken spring means both are bad, but do ask. If springs are the same age and wear is visible on both, replacing both now prevents a second service call in six months.
Ask whether the estimate includes lubrication, balance check, and a warranty on parts and labor. Most springs come with a limited lifetime warranty covering manufacturing defects. Labor warranties typically run one year.
Get two estimates if the price feels high. Compare apples to apples: spring type, quality, labor, and warranty. The cheapest option isn't always the best, but paying 600 dollars when 400 is fair is wasteful.

Spring replacement is one of the most common repairs we handle. It's also one of the most important for safety and door longevity.
Don't live with a broken spring or delay replacement hoping it will fix itself. A failed spring won't heal, and the strain on your opener and door grows daily. Visit our springs service page to learn more about what we offer, then call 857-855-7892 to book your appointment.
How long do garage door springs last? Most springs last 7 to 9 years under normal use, depending on climate and frequency of use. Massachusetts winters can shorten lifespan due to metal fatigue from temperature changes.
Can I replace a garage door spring myself? We don't recommend it. Springs are under extreme tension and release suddenly if mishandled, causing serious injury. Professional installation is safer and usually cheaper than a hospital visit.
Why did my spring snap without warning? Springs wear gradually but can fail suddenly when metal reaches its fatigue limit. Rust, cold weather, lack of lubrication, and heavy use accelerate failure. Regular maintenance catches wear early.
Is it okay to replace just one spring? If only one spring is broken and the other looks new, one replacement may work temporarily. However, if both springs are the same age, replacing both now prevents a second failure soon.
How much does spring replacement cost? Torsion spring replacement typically costs 300 to 500 dollars total. Extension spring replacement runs 200 to 400 dollars. Prices vary by location, spring type, and labor rates in your area.
