Why Your Garage Door Spring Snaps in Green Bay Winters

If you’ve ever heard a loud bang from the garage on a frigid Green Bay morning, there’s a good chance a torsion spring just let go. Here’s why it happens so often here — and what to do about it.

Cold makes steel brittle

Garage door springs are wound steel under enormous tension. When temperatures swing from a thaw to -10°F (a normal week in Green Bay), the metal contracts and becomes more brittle, and an already-worn spring finally fails.

Springs have a lifespan

Most springs are rated for about 10,000 cycles — roughly 7 years of normal use. If your home is in Allouez, De Pere or Howard and the door is the original, it’s living on borrowed time.

What to do when it snaps

• Don’t keep hitting the opener — you can burn out the motor or bend the track.
• Don’t try to lift a heavy door with a broken spring; it’s a serious injury risk.
• Call a local pro for a same-day replacement.

Prevent the next one

A quick fall tune-up — lubrication, balance check, and a look at the cables — catches a tired spring before it strands your car. Call Green Bay Garage Door Pros at [PHONE] to get on the schedule before the deep cold hits.
