Garage Door Spring Replacement Cost in Denver (2026)
Updated June 2026 · 6 min read
A broken garage door spring is the #1 service call we run on classic Denver bungalows — those one-car, 8' × 7' wood or steel doors common in Wash Park, Berkeley, Park Hill, and Sunnyside. Here's exactly what it costs to replace one in 2026, with no upsells and no mystery line items.
The short answer
All-in for a single bungalow garage door spring replacement in the Denver metro — parts, labor, and a 5-year warranty. Most jobs land at $320.
Torsion vs. extension springs
About 80% of Denver bungalow doors built after 1995 use a single torsion springmounted above the door. Older detached garages — especially pre-1980s — often still run two extension springs along the horizontal tracks. Pricing differs:
| Spring type | Parts | Labor | Total |
|---|---|---|---|
| Single torsion (bungalow) | $95 – $160 | $165 – $220 | $260 – $380 |
| Pair of extension springs | $70 – $120 | $175 – $230 | $245 – $350 |
| Dual torsion (16' double door) | $180 – $260 | $200 – $260 | $380 – $520 |
Why Denver pricing runs slightly higher
- Altitude + dry air shortens spring life — we install high-cycle (20,000+) springs by default, not the 10,000-cycle builder-grade stock.
- Bungalow garages are often detached with limited headroom, which adds 15–20 minutes of labor.
- Front Range temperature swings (a 60°F day-to-night delta isn't unusual) demand correctly-tuned winding turns — not a guess.
What should be included in the price
- New high-cycle spring (matched to door weight, not just door size)
- New end bearings and center bearing plate if worn
- Cable inspection and re-tensioning
- Door balance test and opener force adjustment
- Written 5-year parts + 1-year labor warranty
Red flags to avoid
Watch out for:
- Quotes under $150 — almost always builder-grade springs with no warranty.
- "Free service call" companies that show up and quote $700+.
- Replacing only one spring on a dual-torsion door (the other will fail within months).
DIY? Don't.
A loaded torsion spring stores enough energy to break a wrist or worse. We get two or three calls a year from Denver homeowners who tried it. The $250 you'd save isn't worth the ER visit — and most hardware-store springs are 10,000-cycle stock that'll fail in 3–4 years anyway.
Broken spring right now? We're usually there same-day.
