Why winter breaks garage doors
Cold does three things to a garage door. It makes spring steel more brittle, so a spring near the end of its life is far more likely to snap on a frigid morning. It thickens old grease and stiffens rollers and hinges, making the opener work harder. And moisture freezes at the bottom of the door, sometimes sealing it to the concrete. That is why the coldest weeks of the DeKalb winter bring the most broken-spring and stuck-door calls of the year.
What to do before the cold sets in
A few steps make a real difference. Clean out the old, gummed-up lubricant and re-apply a proper garage-door lubricant to the springs, rollers, hinges, and opener rail — never use WD-40, which is a cleaner, not a lubricant. Check the weather seal along the bottom so the door does not freeze down, and clear ice and packed snow from the threshold. Most important, have the springs and balance checked, since winter is exactly when a tired spring gives out.
The value of a fall tune-up
The simplest way to winter-proof a door is a fall tune-up. We lubricate everything correctly, adjust the balance so the opener is not straining against a heavy door, inspect the springs and cables for wear, and test the safety reverse. If a part is close to failing we catch it now, on your schedule, instead of during a cold-snap emergency. For $79 it is cheap insurance against the most common winter breakdowns.
