Garage Door Spring Replacement: Costs, Safety, and Why You Should Never DIY
You pressed the garage door button and heard a loud bang. Now the door won't open. That bang was your torsion spring snapping — and it's one of the most dangerous components in your home.
Why garage door springs are dangerous
A standard garage door torsion spring holds 200+ pounds of tension. When it breaks, it releases that energy instantly. Attempting DIY replacement has caused severe injuries and deaths. This is the one home repair that should always be left to professionals.
Torsion vs extension springs
Torsion springs mount above the door on a metal shaft. They're stronger, safer, and last longer (15,000-20,000 cycles). Extension springs mount on the sides and stretch. They're cheaper but less safe and shorter-lived (10,000 cycles).
Replacement costs
- Single torsion spring: $150-$300 installed
- Pair of torsion springs: $200-$400 installed
- Extension spring pair: $100-$250 installed
- High-cycle torsion springs: $250-$500 installed
- Emergency/same-day service: add $50-$100
How to prevent premature spring failure
- Lubricate springs with white lithium grease twice per year
- Schedule annual professional tune-ups
- Replace both springs at the same time (even if only one broke)
- Upgrade to high-cycle springs if you open your door 4+ times daily
Most garage door springs last 7-12 years with normal use (2-4 cycles per day). If your springs are over 8 years old, proactive replacement is cheaper and less disruptive than waiting for them to break.
