What Causes Garage Door Springs to Break?
A broken spring is the most common garage door failure. One loud bang, and the door will not lift. Knowing why springs break helps you slow the wear and plan for replacement. Here are the main causes.
Normal Wear From Everyday Use
Springs balance the weight of the door, and every open and close adds stress to the steel. A standard spring is rated for about 10,000 cycles, which is roughly 7 to 10 years of normal use, and This Old House puts torsion spring life at 8 to 15 years depending on quality. Wear is the leading cause, and it is unavoidable. Higher-cycle springs simply last longer.
Rust and Utah’s Moisture Swings
Moisture is the enemy of steel. Rust increases friction and weakens the coil, so a rusted spring breaks sooner. Snow, melt, and humidity all speed this up. A light coat of lubricant a couple of times a year slows rust and extends the spring’s life.
Cold Winters
Utah winters put extra strain on springs. Steel contracts in the cold, and a spring already weakened by years of cycling often gives out on the coldest mornings. This is why broken spring calls climb through winter.
The Wrong Spring Size
A spring has to match the weight of the door. An undersized spring works harder on every lift and burns through its cycles early. This often follows a cheap or rushed replacement. Correct sizing is one reason spring work belongs with a professional.
Skipped Maintenance
Neglect shortens spring life. A door that never gets inspected or lubricated wears faster across every part. A yearly check of the balance, the coil, and the hardware catches problems before a spring snaps.
Why This Is Never a DIY Repair
A torsion spring holds enough stored tension to cause serious injury when it releases. The U.S. Consumer Product Safety Commission documented dozens of garage door deaths and thousands of injuries before federal safety standards took effect in the early 1990s, as noted on its 50-year safety review. Do not try to lift a door with a broken spring, and do not attempt the swap yourself. Utah homeowners schedule broken spring repair Utah with a company like Sunny Garage Doors, who replace both springs and reset the balance safely.
Slow the Wear, Plan the Replacement
You cannot stop springs from wearing, but you can stretch their life. Lubricate twice a year, keep rust off, and replace both springs together when one goes. For more home improvement ideas, keep up with the parts of your home that wear over time. A little attention now saves you from a door stuck shut later.
