Broken Garage Door Spring
in St. Paul, MN
A broken garage door spring is one of the most common calls we get from homeowners in St. Paul. Torsion springs, the thick coiled springs above the door, are rated for a set number of cycles. Winters here push temperatures well below freezing, which stresses metal and shortens spring life. Leave a broken spring alone and the door becomes a dead weight that can injure someone or come off the track entirely.
Quick Answer
Garage door springs break because they wear out over time, and St. Paul's cold winters make metal brittle faster. The fix is replacing the spring with the right size for your door's weight. A technician has to do this safely because the spring is under extreme tension. If your door won't open or slammed shut, stop using it and call (218) 274-5818 for an inspection.
Telltale Signs
Warning Signs to Watch For
- The door won't open at all, even with the opener running
- You hear a loud bang from the garage, like a gunshot, often at night
- The door opens a few inches then stops
- The torsion spring above the door has a visible gap or separation
- The door feels extremely heavy when you try to lift it by hand
- One side of the door hangs lower than the other
Root Causes
What Causes Broken Garage Door Spring?
Normal Cycle Wear
Every spring is rated for roughly 10,000 open-close cycles. In a busy St. Paul household, that adds up to about seven to ten years before the metal fatigues and snaps. There is no way to prevent this wear, only to replace the spring before it fails.
The Fix
Torsion Spring Replacement
A technician removes the old spring, measures the door weight, and installs a correctly rated replacement spring. Getting the rating right matters because an undersized spring will fail again quickly.
Cold Weather Metal Fatigue
St. Paul regularly sees temperatures below zero in January and February. Metal contracts in extreme cold, and a spring that is already near the end of its life can snap on the first lift of a frigid morning. This is why spring failures cluster in winter here.
The Fix
Cold-Rated Spring Upgrade
Replacing worn springs before winter with springs made from oil-tempered steel reduces cold-weather failures. The oil-tempering process keeps the metal from becoming brittle in low temperatures.
Rust and Corrosion
Road salt gets tracked into garages all winter in St. Paul neighborhoods like the East Side and Payne-Phalen. That salt moisture sits on the spring coils and causes rust, which eats into the metal and weakens it faster than normal cycling alone.
The Fix
Spring Replacement and Lubrication
Rusted springs need to come out because rust cannot be reversed. After installing a new spring, a technician applies a garage door lubricant to the coils twice a year to slow future corrosion.
