Common causes in Denver
Metal fatigue from cycle count
Standard 10,000-cycle springs last roughly 7 years for the average Denver household. High-cycle springs (25,000+) are available for busy homes and HOAs.
Cold-snap brittleness
Front Range temperature swings from 60°F to single digits in 24 hours weaken the steel. Most snapped-spring calls we run hit in December and January.
Undersized or mismatched springs
Builders often install a single spring on a heavy double door. We re-spec to a balanced pair that doubles the lifespan and protects the opener.
How we fix it
- Step 1
On-site diagnosis
Measure wire size, inside diameter, and length; confirm door weight.
- Step 2
Replace in pairs
Even if only one snapped, we replace both so the door stays balanced.
- Step 3
Re-balance & test
Door should float at the halfway point. We tune until it does.
- Step 4
Lube & safety check
Rollers, hinges, bearings, and a 25-point inspection — included.
FAQ
Can I open the door myself with a broken spring?
No — the door weighs 150–300 lb and the opener isn't designed to lift it alone. Forcing it can strip the opener gear or bend the top panel. Leave it closed and call us.
Why replace both springs if only one broke?
Springs wear at the same rate. The second one is days or weeks behind the first, and replacing it now costs about the same labor while doubling the warranty window.
Are your springs warrantied?
Our standard torsion springs carry a 7-year warranty. High-cycle springs are warrantied for 12 years or 25,000 cycles.
Is it safe to replace a spring myself?
A wound torsion spring stores enough energy to break bones or worse. Even seasoned DIYers send this one to a pro. Our techs use proper winding bars and lock-off procedures every time.
