The Ultimate Guide to Garage Door Spring Repair Why you Should Never DIY
Garage door spring replacement is the one repair you should never DIY. A torsion spring stores enough energy to lift a 150–200 lb door dozens of times a day — and that energy releases violently if a winding bar slips. Spring work sends people to the ER every year. Here's why it's a pro job, what it actually involves, and what it costs in Austin.
Why springs are so dangerous to touch
A torsion spring is wound under extreme tension on a bar above the door. To replace it you have to control that tension with winding bars and let it out in careful, measured turns. If a bar slips, or you use the wrong size spring, it can whip loose with enough force to break bones or worse. Extension springs (the long ones along the tracks) are just as risky — they can launch across a garage when they fail.
What a proper spring replacement involves
- Measuring the existing spring (wire size, inside diameter, length) so the replacement is rated for your exact door.
- Safely unwinding the old spring and winding the new one to the correct turns.
- Checking the cables, drums, and bearings — the parts that work alongside the spring.
- Balancing the door so the opener isn't carrying weight it shouldn't.
We almost always recommend replacing springs in pairs — if one has reached the end of its life, the other is close behind, and doing both avoids a second breakdown weeks later.
What spring replacement costs in Austin
Residential torsion springs start at $179 per spring; commercial doors use much larger springs that can reach $700+ each. The $69 diagnostic is credited when you book the repair, and you get the exact price in writing before any work begins.
The bottom line
"Garage door spring kits" exist, but the few dollars saved aren't worth an ER visit or a door that's now unsafe. A trained tech with the right bars and the correctly rated spring does it safely in under an hour — and it's backed by our 3-year parts and 90-day labor warranty.
Garage door spring repair — FAQs
Can I just replace the spring myself to save money?
We strongly advise against it — torsion springs are under extreme tension and cause serious injuries every year. It's a job for a trained tech with the right winding bars.
Should I replace one spring or both?
Both. They wear at the same rate, so replacing the pair avoids a repeat failure and a second trip charge soon after.
