Signs of a Broken
Garage Door Spring
The three clearest signs of a broken garage door spring are a loud bang or pop from the garage, a gap between the coils of a torsion spring, and a door that is suddenly heavy or will not lift. Do not use the door or the opener until it is fixed.
The fix is usually both springs: a torsion pair is $145 to $520 installed on our estimate, or $145 to $715 after hours (October 2026). Signs from Precision Garage Door Service, A1 Garage Door Service and DASMA, read 23 October 2026.

What to do if a spring has broken
- Stop using the door and the opener. A1 Garage Door Service says a door with a broken spring can be opened but that it is unsafe and can cause major damage.
- Leave the springs, cables and bottom brackets alone. DASMA Technical Data Sheet 174 says occupants should not attempt to remove, adjust or repair doors or springs, which move under extreme tension.
- Call a technician and ask for both springs. DASMA says to replace both even if one is not broken.
- Ask for every line separately: springs, labor, service call, and any cables or emergency fee.
Can a weak spring damage the opener?
It can shorten its life. DASMA Technical Data Sheet 190 says a spring that does not meet the door's counterbalance requirement can reduce the cycle life of a door assembly or a garage door motor, and can be a safety issue. A1 Garage Door Service lists an opener that struggles or sounds louder than normal as a warning sign.
Worn but not broken
A spring that looks stretched, wavy, cracked or rusty, or a door that tilts or feels heavier than it did, is worth booking before it breaks: planned in normal hours, a torsion pair is $145 to $520 on our estimate, against $145 to $715 with an emergency fee.

How we price this: Our ranges are estimates built from published inputs, not quotes: retail spring prices, the service-call and hourly rates in Yelp's cost guide, and job times from HomeAdvisor and Yelp. Low ends are rounded down and high ends up to the nearest $5.

- Pair of torsion springs replaced (pair; estimate from stated inputs; includes parts, labor, service call): $145 to $520. parts 2 x $35.38 to 2 x $157.94, plus labor $75 to $200 (a $75 to $100 service call covering the first hour, plus up to one more hour at $100): $145.76 to $515.88, rounded out to the nearest $5.
- One torsion spring replaced (per spring; estimate from stated inputs; includes parts, labor, service call): $110 to $360. parts $35.38 to $157.94, plus labor $75 to $200 (a $75 to $100 service call covering the first hour, plus up to one more hour at $100): $110.38 to $357.94, rounded out to the nearest $5.
- Pair of torsion springs after hours (pair; estimate from stated inputs; includes parts, labor, service call, emergency fee): $145 to $715. torsion pair $145.76 to $515.88, plus an emergency fee of $0 to $199: $145.76 to $714.88, rounded out to the nearest $5.
- Pair of extension springs replaced (pair; estimate from stated inputs; includes parts, labor, service call): $130 to $350. parts 2 x $29.92 to 2 x $72.90, plus labor $75 to $200 (a $75 to $100 service call covering the first hour, plus up to one more hour at $100): $134.84 to $345.80, rounded out to the nearest $5.
Parts are priced at what the two suppliers charge the public. Installers buy for less and many mark parts up, and neither figure is published, so a quote's parts line can be higher than ours.
Wage check: The BLS puts the median mechanical door repairer (the occupation that includes garage door mechanics) at $26.79 an hour (May 2025). Wages are 70.0% of private-industry employer costs (June 2026), so that technician costs an employer about $38.27 an hour before the van, insurance, overhead and profit. Yelp's $40 to $100 hourly rate sits at or above that cost, which is what a billed rate should do. (BLS OEWS, 49-9011 Mechanical Door Repairers; BLS Employer Costs for Employee Compensation)
Frequently Asked
What are the signs of a broken garage door spring?
A loud bang or pop from the garage, a visible gap between the coils of a torsion spring, and a door that is suddenly heavy or will not lift. Precision Garage Door Service calls the gap and the pop classic signs of a broken torsion spring; A1 Garage Door Service says a loud bang often means a spring snapped. Replacing a pair of torsion springs is $145 to $520 on our estimate (October 2026).
Can I still use my garage door with a broken spring?
No. A1 Garage Door Service says you can open a door with a broken spring, but it is unsafe and can cause major damage. DASMA's Technical Data Sheet 190 says a spring that does not meet the door's counterbalance requirement can reduce the cycle life of a garage door motor, so leave the opener off too. DASMA says spring systems should be repaired only by trained professionals.
Do squeaky garage door springs mean they are failing?
Not necessarily. DASMA says springs can squeak from normal use and that this does not necessarily indicate a problem. It suggests a spray-on lubricant made for garage doors first, and a technician if the noise persists.
If one spring broke, should I replace both?
Yes. DASMA says: "If your door has two springs, replace both, even if one is not broken." On our estimate a torsion pair is $145 to $520 and a single torsion spring $110 to $360, because the labor is the same visit.
What does an emergency spring repair cost?
On our estimate a pair of torsion springs after hours is $145 to $715, against $145 to $520 in normal hours. The difference is the emergency fee, which some companies charge and some do not, so ask when you call.
