Fall Garage Door Checklist for North Shore Homes

September on the North Shore is easy on a garage door. The heat is gone and the ice hasn't arrived yet. That makes it the best time to find small problems, before cold weather turns them into a door that won't open on a school morning.

Why fall is the right time

Cold is hard on garage doors in three ways, and Clopay's own guide to cold-weather problems covers all three:

• Lubricant stiffens. Old grease hardens and gets gummy in the cold, so the door drags and the opener works harder.
• Seals freeze to the slab. Water collects under the door, freezes, and holds it down. Forcing it can rip the bottom seal.
• Springs get more brittle. Spring steel that's already near the end of its life is more likely to snap in cold weather.

Fall is also the start of nor'easter season. NOAA notes these storms are most common between September and April, and most severe in winter. A door that's already out of balance or has a torn seal won't handle wind-driven rain well. (We cover storm prep in a separate post.)

1. Look it over (5 minutes)

With the door closed, stand inside and look at:

• Springs: a gap in the coil of a torsion spring above the door means it's broken. Don't run the door.
• Cables: frayed strands or a cable that looks slack or loose on its drum.
• Rollers and hinges: cracked wheels, wobbly rollers, or hinges with cracks around the screws.
• Tracks: dents, loose bolts, and leaves or grit collected in the bottom of the track.
• Panels: cracks, rust spots on steel, or soft, split wood near the bottom.
• Photo-eyes: both sensors pointing at each other, lenses clean, and mounted no more than 6 inches above the floor. That height is in DASMA's opener safety guide.

2. Balance test (3 minutes)

DASMA's safety and maintenance guide describes this test. With the door fully closed, pull the opener's emergency release to disconnect it. Lift the door by hand. It should move freely, and when you let go about 3 to 4 feet off the floor it should stay put.

If it slides down or shoots up, the springs are out of adjustment or wearing out. That's a job for a technician. Close the door, reconnect the opener, and book a tune-up.

3. Safety-reverse test (2 minutes)

Reconnect the opener and open the door. Lay a 2x4 flat on the floor in the door's path and close the door with the remote or wall button. The door should stop when it touches the board and reverse. Then wave something in front of a photo-eye while the door is closing. It should stop and go back up.

DASMA specifies a 2x4 laid flat, not a paper towel roll, because the test checks that the door reverses when it's about 1.5 inches off the floor. If your door fails either test, stop using the remote until it's fixed. Our reversing-door page covers the common causes.

4. Lubricate the right parts (5 minutes)

Clopay's lubrication guide recommends a silicone-based spray or white lithium grease, applied to:

• Hinge pins
• Roller bearings on steel rollers
• Torsion springs and the bearing plates at each end

And a few things not to do:

• Don't lubricate the tracks. Rollers are supposed to roll, not slide, and grease in the track collects dirt.
• Don't use WD-40 or household oil. Clopay says they attract dust and grit.
• Wipe off the extra and run the door a few times to spread it.

Clopay suggests every six months for average use and every three months if the garage is your main way in and out. Our garage door maintenance checklist covers the rest of the year.

5. Check the seals

Close the door and look at the bottom from inside. Daylight along the floor, a flattened or cracked rubber seal, or leaves blowing in all mean the bottom seal is done. Check the vinyl stop molding along the sides and top too.

A good bottom seal is the cheapest winter upgrade there is. It keeps out cold air, water and critters, and it helps stop the puddles that freeze the door to the slab. Also sweep the slab where the door lands. A clean, dry landing spot freezes less.

6. Clear the path

Fall on the North Shore means leaves, acorns and pine needles. Clear them from the tracks, the threshold and the photo-eyes. Move rakes, bikes and bins away from the door's path and from the sensors. If something blocks the photo-eye beam, the door won't close.

What to leave to a technician

Springs, lift cables, cable drums and the bottom brackets that hold the cables are all under heavy tension. DASMA's guide is blunt about it: only qualified people should adjust springs. If your balance test failed, a cable looks frayed, or the door is noisy and jerky, that's the time for a professional visit, not a YouTube video.

A tune-up covers the tension parts, balance, opener force settings and safety tests in one visit. Booking it in the fall means it's done before the first cold snap, when calls for broken springs and frozen doors pick up.
