Fall Garage Door Maintenance Checklist Before Winter
By HUSH Garage Door Service· Published
Before Ottawa's first freeze, run 5 checks on your garage door: balance and springs, lubrication, rollers and cables, the bottom seal, and the safety reverse. Fall is when a worn part is cheapest to fix.
Why do garage door maintenance in the fall?
Fall is the single best time to service a garage door in Ottawa, because winter is what exposes every weakness.
| Fall job | Why now |
|---|---|
| Lubricate rollers, hinges, bearings, springs | Old grease is what drags at minus fifteen |
| Replace a hardened bottom seal | A worn seal is what bonds the door to the slab |
| Run the balance test | A tired spring snaps on the first cold morning, not in July |
| Test both safety systems | Cold shifts brackets and fogs lenses |
| Tighten the hardware | Hundreds of summer cycles have loosened it |
Cold makes tired steel brittle, stiffens lubricant, and freezes a worn seal to the slab. A part that was merely worn in October is the part that fails on the coldest January morning.
Doing the work now means you find the weak link on your own schedule, not when your car is trapped and it is minus twenty. This checklist is the fall once-over; for the deeper season-long picture see our guide on garage doors in Ottawa winters. For the parts of that season you should hand to a technician, the winter maintenance page sets out what the visit covers.
What are the 3 checks on a fall garage door checklist?
Work through these 3 checks in order. The first two take about 15 minutes of your own time. The spring and cable items are where a technician earns their keep.
Test the balance and look at the springs
With the door fully closed, look at the springs and cables first without touching them. A gap in the coil, a clean break or a loose cable means stop there and call, and never adjust a spring yourself. If they look whole, disconnect the opener with the red release cord and lift the door by hand to about waist height. A healthy door stays put.
One that drops or flies up is out of balance, which points to the springs. A spring near the end of its roughly 10,000 cycle life is exactly what snaps in the first cold snap.
Lubricate everything with a cold-rated spray
Wipe the tracks clean, then spray a silicone or white lithium garage door lubricant on the rollers, hinges, bearings and the springs. This is the highest-value five minutes you can spend, a dry, cold roller drags and squeals, and dry hinges crack. Avoid WD-40 as the lubricant; it is a cleaner, not a grease.
Check the rollers, cables and hardware
Spin each roller and feel for grinding or flat spots, and look along the lift cables for fraying or rust. Tighten any visibly loose bolts on the hinges and brackets by hand. If a cable looks frayed or a roller is shot, book it now, because a cold morning is the worst time for either to fail.
How do you check the bottom seal and threshold before winter?
The bottom seal is the rubber strip that keeps cold air, water and snow out, and it is the part most likely to let your door freeze to the ground. Press on it: if it is cracked, hard or flattened, it is no longer sealing, and a worn bottom seal will let meltwater run under the door and refreeze overnight.
Replace a tired seal before winter rather than during it, and keep the threshold swept clear of snow and ice so water cannot pool and bond the seal to the concrete. A clear, dry threshold and a fresh, flexible seal are what stop a common winter problem, a door frozen shut before work. A wooden door that stops closing properly in winter, garage or house, is usually swollen by moisture or pushed out of line by frost heave, so check the bottom edge for soft, swollen wood while you are down at the seal.
How do you test the opener and the safety reverse before winter?
With the door balanced and lubricated, the opener moves it with almost no effort. If the opener strains, reverses, or runs slow, the door is dragging and needs the mechanical fixes above before you touch a single opener setting. Never crank up the opener force to muscle a binding door. Raising the down force is what stops a door reversing off an obstruction, which is the one safety function the opener must never lose.
Finish by testing the safety reverse: lay a 2x4 flat on the floor under the middle of the door and close it. The door must reverse as soon as it touches the board. Then wave something through the photo-eye beam while it closes and confirm it reverses. If either fails, the sensors or the auto-reverse need service before winter.
Which winter checks should you leave to a technician?
The cleaning, lubricating, balance test and threshold work are all safe to do yourself. The spring, cable and bottom-bracket items are not, because they are under high tension and can injure you, so those are the parts to hand to a technician.
If your fall check turns up a worn spring, a frayed cable, a binding track, or a door that fails the balance test, book a tune-up before the cold sets in. A technician handles the high-tension parts safely, adjusts the opener, and sends your door into winter ready, which is far cheaper than an emergency repair in January.
