Broken Garage Door Springs
in Rochester, MN
Garage door springs do all the heavy lifting. They counterbalance the weight of the door so you can open it with one hand or let the opener do the work. In Rochester, the deep cold we get every winter — temperatures well below zero — makes steel springs go brittle faster. When a spring snaps, the door either won't move at all or drops hard if you force it.
Quick Answer
Garage door springs break because they wear out after years of use. Rochester winters make this worse — cold temperatures make the metal brittle, and springs snap more often in January and February than any other time of year. A technician replaces the broken spring with a correctly sized one matched to your door's weight. Don't try to open the door until the spring is replaced — the door can fall.
Telltale Signs
Warning Signs to Watch For
- The door won't open even when you press the opener button
- You hear a loud bang from the garage, like a gunshot, when the spring breaks
- The door opens a few inches and then stops or feels extremely heavy
- You can see a gap or separation in the coil of metal above the door
- The opener motor runs but the door doesn't move
- One side of the door hangs lower than the other when partially open
Root Causes
What Causes Broken Garage Door Springs?
Normal Wear and Fatigue
Springs are rated for a set number of cycles — usually around 10,000 opens and closes. A typical Rochester household cycles their door four or more times a day, which means an average spring lasts about seven years before the metal fatigues and snaps.
The Fix
Spring Replacement with Correct Cycle Rating
A technician removes the broken spring and installs a new one sized for your door's exact weight. Upgrading to a higher cycle-rated spring — 20,000 or 30,000 cycles — means you won't be dealing with this again as soon.
Cold Weather Metal Stress
Rochester regularly sees temperatures drop below minus ten degrees Fahrenheit in January and February. Steel contracts in that kind of cold, and a spring that was already worn gets pushed past its limit. That's why most spring failures here happen on the coldest mornings of the year.
The Fix
Spring Replacement and Lubrication
After replacing the spring, a technician applies a cold-rated lubricant to the coils. This helps the metal flex instead of crack when temperatures fall hard overnight.
Rust and Corrosion
Road salt gets tracked into garages all winter long across Rochester. Salt vapor settles on the springs and eats into the surface of the metal. Rust weakens the steel so it breaks earlier than it should — sometimes after only a few years.
The Fix
Spring Replacement and Rust Prevention
The corroded spring comes out and a new one goes in. Regular lubrication with a non-water-based spray keeps rust from forming on the new spring through future winters.
