Philadelphia winters put real stress on a garage door — freeze-thaw cycles swell and shrink wood trim, road salt corrodes hardware, and cold makes torsion springs more brittle right when they're under the most load from a heavy, cold door. Here's a practical checklist to run before the first hard freeze.
1. Lubricate the moving parts. Rollers, hinges, and the torsion spring itself should get a light coat of a garage-door-specific lithium grease (not WD-40, which strips lubricant rather than adding it) before winter. This cuts down on the stiff, jerky movement that overworks the opener motor in cold weather.
2. Check the weatherstripping. Run your hand along the bottom seal and side stops. Cracked or flattened weatherstripping lets in cold air and lets snowmelt pool at the base of the door, which speeds up rust on the bottom bracket.
3. Test the balance. Disconnect the opener (pull the emergency release) and lift the door halfway by hand. It should stay in place. If it drops or shoots up, the springs are compensating incorrectly for the door's weight — a sign of spring fatigue that gets worse, not better, in the cold.
4. Look at the springs themselves. Rust spots, visible gaps between coils, or a spring that looks stretched compared to its neighbor are warning signs. Torsion springs are under massive tension and are not a DIY repair — if you see wear, that's a call, not a project.
5. Inspect the cables and bottom brackets. Fraying at the cable ends or a bent bottom bracket are common after a door has been forced open manually during a stuck-in-cold moment. Both are cheap to fix now and expensive to ignore.
6. Clear the tracks. Road salt and grit tracked in from car tires builds up in the vertical tracks over winter. A quick wipe-down keeps rollers running true and reduces strain on the opener.
If anything on this list turns up wear, worn parts don't get better with warmer weather — they get replaced under worse conditions, usually during an emergency call.
