A broken garage door spring is the single most common repair call we get across Greater Boston. Your door makes a loud bang, stops moving, or suddenly feels impossibly heavy. You call around trying to figure out what it's going to cost. Here's a straight answer — with real numbers for the Greater Boston and South Shore market in 2026.
Spring broke this morning? Call us at (781) 222-DOOR or submit a repair request. Same-day service is available across the South Shore. We stock springs for all standard door sizes on every truck.
What a Torsion Spring Does
Your garage door weighs between 100 and 300 pounds depending on the material and size. The torsion spring — mounted horizontally above the door on a metal shaft — is wound under thousands of pounds of torque. Its job is to counterbalance that weight so your opener only has to lift a few pounds of net force.
When the spring breaks, the opener is suddenly lifting the full dead weight of the door. Most openers can't do it. The door won't move, or it moves a few inches and the opener stops. The spring itself makes a sharp bang when it goes — often loud enough to wake the neighborhood at 6am.
Springs are rated by cycle count. Standard residential springs are rated for 10,000 cycles. A home that opens and closes 4 times per day hits that mark in about seven years. High-cycle springs (25,000–50,000 cycles) cost more upfront but dramatically reduce replacement frequency — worth considering if you run the door heavily.
What Garage Door Spring Repair Costs in Greater Boston
Parts additional — full quote before any work begins
| Spring Type / Scenario | Greater Boston Range (2026) |
|---|---|
| Single torsion spring (standard, one door) | $225 – $325 total |
| Double torsion spring (heavier or wider doors) | $290 – $400 total |

| Spring replacement + cable replacement (bundled) | $350 – $550 total |
These are all-in numbers: service call, parts, and labor. The range depends on your door size and weight, spring specifications, and whether cables need attention at the same time.
Why We Recommend Replacing Both Springs at Once
Most double-car doors use two torsion springs. If one breaks, the other is typically the same age and has run the same number of cycles. Replacing just the broken spring means the other will likely fail within months — and you'll pay a second service call. Replacing both at the same time saves money in the long run and eliminates the second emergency.
What's Included in a Service Call
Our $189 service call covers the technician arriving at your home, performing a full diagnostic on your door system, and completing minor adjustments (lubrication, limit adjustments, sensor alignment). Parts are not included in the base rate — but you receive a written quote before any repair begins. You decide whether to proceed.
For a standard spring replacement, we typically complete the repair in the same visit — usually 45–75 minutes. We stock the most common spring sizes and weights on every truck. Unusual door configurations (extra-wide, custom height, commercial-grade) may require ordering parts, though most residential doors are covered with our standard inventory.
Before you call around for quotes: The lowest quote often reflects cut-rate springs with a 2,000-cycle rating. These fail in 18 months instead of 7 years. Ask any company what the cycle rating is on the spring they're installing — that number tells you what you're actually buying.
Why You Shouldn't Replace Springs Yourself
The internet has tutorials for DIY spring replacement. We're not going to link to them, and we're going to be direct about why this is dangerous.
A torsion spring under full tension contains stored energy equivalent to a powerful projectile. Improper installation, a slipped winding bar, or the wrong spring gauge can cause the spring to release suddenly — at your face or hands. The Consumer Product Safety Commission documents thousands of garage door injuries each year; spring-related incidents are the most severe.
This is not a "it's technically possible but just easier to hire someone" situation. The risk-to-reward ratio is genuinely bad: you save $100–$150 in labor and assume the risk of serious injury. The CPSC explicitly recommends professional replacement for torsion spring systems.
Do not attempt to replace or adjust torsion springs yourself. This applies even if you watched a video and it looks simple. The stored energy in a wound spring is substantial and unpredictable when something goes wrong.
What to Expect on the Day of Service
- We confirm your appointment window — typically a 2-hour window. You'll get a text when the tech is en route.
- The tech inspects the full door system — not just the spring. Cables, rollers, tracks, opener limit settings, and safety sensors are all checked.
- You receive a written quote before any parts are ordered or installed. No surprise charges.
- Repair is completed in the same visit for standard residential doors — usually 45–75 minutes.
- The tech walks you through what was replaced, shows you the failed component, and demonstrates the door operating correctly before leaving.
