Massachusetts winters test every moving part of a garage door. Temperatures swing from 40 degrees to below zero, ice storms knock the power out, road salt gets tracked in, and snow piles up against the door. These are the five cold-weather problems that come up every winter, what causes each one, and what to do about it.
If your door has already failed and you need it working now, start with what to do when your garage door won't open, then see what an emergency call costs.
1. A Spring Snaps on a Cold Morning
You press the button on the coldest morning of the week and nothing happens, or the door lifts a few inches and stops. Maybe you heard a loud bang from the garage overnight. That is a broken spring.
Why it happens: Springs are rated in cycles, and a common rating for a standard spring is 10,000 (one cycle is one open and one close). At about four cycles a day, that is roughly seven years. A spring near the end of its rating already has fatigue in the steel, and a cold morning, stiff grease and a seal frozen to the floor all add strain on the day it finally lets go.
What to do: Stop pressing the button, and don't try to lift the door. If it feels like 100 lbs or more, the spring is broken: leave it closed and call for spring replacement. If the door hangs crooked after the bang, a lift cable may have come off too: broken garage door cable covers what not to touch. If your car is trapped, the emergency steps post explains when the red release is safe to use and when it is not. Never pull it with the door partly open and a broken spring, because nothing will hold the door up.
Prevention: If your springs are around seven years old or more going into winter, have them checked. Replacing a worn spring on a scheduled visit means you pick the day, instead of the coldest morning of the year picking it for you. Lubricating the springs before the cold helps a spring with life left in it, but it won't save one at the end of its rating. See how long garage door springs last.
2. The Door Freezes to the Ground
You press the button and hear the opener strain, but the door won't move. Or it lurches up and tears the bottom seal. The cause is ice bonding the rubber seal to the concrete.
Why it happens: Rain, melting snow or condensation collects at the base of the door. When the temperature drops below freezing, that water bonds the seal to the floor. The opener either can't break the bond or breaks it by tearing the seal.
What to do right now: Don't keep hitting the button. Each try strains the opener motor and can strip its gears. Instead:
- Break the ice bond gently with a flat shovel or a putty knife, working along the whole length of the door.
- A hair dryer softens small patches of ice. Never pour hot water: it refreezes, often worse.
- Once the door is free, run it once to confirm it works, then clear the water and snow in front of it.
Prevention:
- Keep the area in front of the door clear of snow and standing water.
- A silicone spray on the bottom seal before a freeze helps stop water bonding to the rubber.
- If it keeps happening, check whether water pools at the door. A seal that is torn, flattened or too stiff to seal also lets water in; weatherstripping can be replaced on its own.
3. Ice in the Tracks and Stiff Hardware
Your door suddenly sounds different: louder, rougher, with new clicks and pops. Or it hesitates or sticks at the same point every time.
Why it happens: Grease thickens in the cold, rollers and hinges stiffen, and every metal part contracts a little. Snow that blows in or drips off a car can freeze in the bottom of the tracks, and a roller that meets ice binds there.
What to do:
- Look in both tracks for ice or debris at the height where the door sticks. A hair dryer melts small buildups; again, no hot water.
- Lubricate the hinges, rollers, springs and bearing plates with a garage door lubricant (silicone or white lithium).
- Check that the track mounting bolts are snug. A door that has been running rough can shake them loose.
- If the door sticks at the same spot with no ice there, look for a dent or a bent section of track. That needs track repair, not more force.
4. The Opener Runs Slow, Stalls or Reverses
The opener used to lift the door easily. Now it labors, stalls partway up, or reverses on the way down for no reason you can see.
Why it happens: Cold thickens the grease in the opener's gears and on the rail, and the door itself is stiffer to move. An opener that was barely coping in the fall may not have the margin in January.
What to do:
- Check the door's balance. With the door fully closed, pull the red release cord and lift the door by hand. About 10-15 lbs is normal. If it is much heavier, the springs are weak or broken: stop, close it gently, and don't lift it further. The opener is fighting a spring problem it can't fix.
- Don't turn up the opener's force settings to push through a stiff door. The force setting is part of what makes the door stop and reverse when something is under it. Fix the balance or the binding instead.
- If an older opener struggles every winter even with a balanced, well-lubricated door, it may be time for a new opener.
Power outages: Winter storms take the power out, and the opener can't run without it. If you need the car out, use the red release only with the door fully closed, lift the door by hand, and lock it again when you're back: a released door can be lifted from outside. An opener with a battery backup keeps working through an outage.
Prevention: Lubricate the rail or chain before winter, and keep the garage as warm as practical. An insulated door helps the opener too.
5. Weatherstripping Cracks and Leaks
You notice drafts, water, or even snow getting in around the edges of the door. Or the bottom seal is cracked, hard, or hanging off in sections.
Why it happens: Rubber and vinyl seals harden in the cold, especially after years of sun and compression. Once they lose their flex, they can't follow the uneven floor and frame, and gaps open up. Freeze-thaw cycles make it worse: water gets into a small crack, freezes, expands, and opens the crack further, over and over through the winter.
What to do: Replace the damaged sections. The bottom, side and top seals are separate pieces and can be replaced independently. The bottom seal usually fails first because it takes the most abuse. See weatherstripping replacement.
Prevention: Inspect the seals every fall before the cold hits, and don't ignore small gaps: they grow once winter starts.
Test the Safety Reversal Before Winter
Cold, frost on the photo-eye lenses and a bumped sensor bracket can all affect how the door reverses. Test it before winter and again every month:
- Lay a 2x4 flat on the floor in the door's path and close the door. It should reverse when it touches the board.
- While the door is closing, pass something through the photo-eye beam near the floor. The door should stop and reverse.
If either test fails, don't use the opener until it is fixed. See the safety sensor troubleshooting guide.
Pre-Winter Checklist
The theme across all five problems is the same: work done before winter prevents emergencies during it.
- Lubricate the springs, rollers, hinges and opener rail with silicone or white lithium spray.
- Check the balance: with the door fully closed, pull the release and lift by hand. About 10-15 lbs is normal.
- Inspect the weatherstripping and replace anything cracked, torn or hard.
- Tighten the hardware: bolts, brackets and track fasteners.
- Test the safety reversal with the board and the photo-eye.
- Clean the tracks and look for dents or bends.
- Consider insulation if the garage is attached and the door isn't insulated. See the insulation guide.
You can do most of this yourself in under an hour. A maintenance visit covers lubrication, a spring tension check, safety testing, track alignment and hardware tightening, including the spring work that needs the right tools.
