Search "garage door spring replacement cost" and you'll find estimates ranging from $95 to $400+. That's a $300 spread for what seems like a straightforward job. Here's why the range is so wide — and what you should realistically expect to pay in Greater Boston.
The Real Cost Breakdown
A fair price for torsion spring replacement in the Boston area (labor + parts) runs as follows:
| Service | Boston Price Range |
|---|---|
| Single torsion spring replacement | $150 – $280 |
| Both springs replaced (recommended) | $220 – $380 |
| Extension spring replacement (per pair) | $130 – $240 |
| Spring + cable inspection & service | $180 – $320 |
If a quote comes in under $100 total, that's a serious red flag. The tech is planning to get in the door on a low number and upsell you dramatically once they're inside.
Torsion vs. Extension Springs — What's the Difference?
- Torsion springs mount above the door on a metal shaft — more expensive to buy but last 2–3x longer. Most Boston homes built after 1990 use these.
- Extension springs run along the horizontal tracks on each side — cheaper parts, more common in older Dorchester and South Boston triple-deckers.
- Always replace both springs at the same time — if one failed, the other is typically within months of failing too, and labor costs make replacing them together far more economical.
Why Boston Spring Costs Are Slightly Higher Than National Averages
Two reasons: labor costs in the Boston metro consistently run 15–20% above the national average, and quality-conscious local companies spec heavier-duty springs specifically for New England's temperature swings. A standard spring that lasts 7–8 years in Atlanta will fatigue in 3–4 years in Boston. The higher upfront cost of quality springs pays for itself in avoided emergency calls.
