Winter Garage Door Care on the South Shore
Damp cold, freeze-thaw nights and road salt are hard on garage doors. Most winter breakdowns announce themselves weeks ahead. Here is what to watch and what to do.
- Frozen seals
- Cold-morning spring breaks
- Road salt

Frozen Bottom Seals
Slush melts off the car, runs under the door and freezes. In the morning the opener pulls against a seal glued to the slab, and something gives: the seal tears, the drive gear strips (from $219), or a tired spring snaps. Keep the threshold clear and dry, and replace a torn seal (from $120).
Cold-Morning Spring Breaks
A spring near the end of its cycles often fails on the first truly cold day. If you hear a bang and the door will not lift, leave it closed and call. One spring starts at $269, a pair at $485.
Signs to catch it in the fall: the door feels heavier by hand, drifts down when released halfway, or the springs are more than about seven years old on a busy door.
Road Salt at the Threshold
Rockville Centre is inland, but road salt rides into every garage on the tires. It collects exactly where the cables and bottom brackets sit. Rinse that corner now and then through the winter and look for rust and broken strands.
A Fall Checklist
- Lubricate hinges, rollers, springs and bearings.
- Check the bottom seal for tears and gaps.
- Test the balance and the auto-reverse.
- Check the opener battery backup, if you have one.
- Book a tune-up (from $119) if anything looks worn.
When to Call Instead
- A bang and a door that will not lift — a broken spring.
- A cable hanging loose or a door rising crooked.
- A hum with no movement after a frozen morning — possibly a stripped gear (from $219).
- A door that keeps reversing after the threshold is clear and dry.

Winter Questions
Answers as of October 2026. Still unsure? Call (516) 442-8171 and describe what the door is doing.
Why does my garage door stick to the ground in winter?
Melted snow runs under the bottom seal and freezes overnight. Do not force it with the opener; free it gently with a plastic scraper or warm (not boiling) water, then dry the threshold.
Why does my garage door reverse in cold weather?
Grease thickens in the cold and the door moves more stiffly, so the opener senses resistance. Lubricate with a cold-rated spray and have the balance and force checked if it keeps happening.
Do garage door springs break more in winter?
Springs wear by cycles, but a spring near the end of its life is more likely to snap on a hard-freeze morning, which is why spring calls jump on the first cold days.
