Garage Door Maintenance Checklist for Illinois Homes
A garage door is the heaviest moving object in most homes and the one that gets the least attention. Twenty minutes twice a year will roughly double the working life of the hardware and prevent most of the emergency calls we run.
Twice a year: the balance test
Close the door. Pull the emergency release cord to disconnect the opener. Lift the door by hand to about waist height and let go.
A balanced door stays put. If it drifts down, the springs are losing tension. If it flies up, they are over-tensioned. Either way the opener is now compensating, and openers are not built to do that for long.
Reconnect the opener by pulling the cord again and running the door once.
Twice a year: look and listen
Run the door and watch it move. It should travel smoothly, evenly, and stay square in the track. Jerking, hesitation or one side leading the other means something is binding.
Look at the springs for gaps, the cables for fraying or rust, the rollers for flat spots, and the track for dents or spreading. Look at the hinges for cracks around the bolt holes.
Twice a year: tighten and lubricate
Snug up the hinge and track bolts with a socket wrench. Leave the bottom brackets alone - they are under cable tension.
Lubricate hinges, roller stems, bearing plates and spring coils with garage door lubricant or light lithium grease. Wipe off the excess. Do not lubricate the track.
Every month: test the safety features
Place a block of wood or a roll of paper towel flat on the floor in the door's path and close the door. It should touch the object and immediately reverse. If it does not, the down force setting needs adjusting.
Wave a broom handle through the photo eye beam near the floor while the door closes. It should stop and reverse. If nothing happens, the sensors need attention.
Before winter
Check the bottom seal. Illinois freeze-thaw cycles pull the rubber out of the retainer and once there is a gap, snow, water and mice find it. A new seal is inexpensive and takes minutes.
Check the weatherstripping down the sides and across the top. Check the floor is level enough that the seal actually meets it.
If the garage is attached or heated, this is the point to think about whether an insulated door would pay for itself.
Before summer
Humidity is what rusts cables, usually at the point where they wrap around the drum. Look closely there.
Check the opener's battery backup, if fitted. Backup batteries typically last two to three years and a dead one is only discovered during an outage.
What to leave alone
Torsion springs, cables, bottom brackets and drums. All four are under or attached to spring tension. Everything on that list can injure you badly, and all four are quick jobs for someone with the right bars and clamps.
