If you woke up this morning and your garage door won't open — or you heard a loud bang when it failed — there's a very good chance a spring broke. Garage door springs do the heavy lifting every single time your door moves, and they're only rated for a certain number of cycles before they give out. When one breaks in St. Charles County, St. Charles Door Pros can usually get there the same day.
Torsion Springs vs. Extension Springs
Most modern garage doors use one of two spring systems. Understanding which type you have helps explain what the repair involves.
🔩 Torsion Springs
Mounted horizontally above the door opening. These wind and unwind to raise and lower the door. Torsion springs are more durable and balanced — most doors built in the last 15 years use them.
Typical lifespan: 10,000–20,000 cycles (7–12 years with average use)
Signs of failure: Loud bang, door won't open manually, visible gap in the spring coil
🔧 Extension Springs
Run along the horizontal tracks on both sides of the door. These stretch and contract as the door moves. Older homes and single-car garages often have extension springs.
Typical lifespan: 7,000–10,000 cycles (5–7 years with average use)
Signs of failure: Door opens unevenly, one side drops, visible broken spring on track
Warning Signs Your Spring Is About to Fail
Springs rarely break without warning. Here's what to watch for before they go completely:
- Door feels unusually heavy when you try to open it manually
- Door opens a few inches then stops
- Visible rust, corrosion, or gaps in the spring coil
- Squeaking or grinding noise when the door operates
- Door opens or closes slower than normal
- The door doesn't stay open at the halfway point — it drifts back down
⚠️ Don't try to repair garage door springs yourself. Torsion springs are under extreme tension — enough to cause serious injury if released incorrectly. This is one repair where calling a professional isn't just recommended, it's the safe choice. Our technicians have the proper tools and training to handle this safely.
