5 garage door maintenance steps to avoid expensive repairs

CHICAGO (WLS) -- A little preventive maintenance can go a long way. Especially when it comes to your garage door, the largest moving object in your home.

In this week's Easy Fix, DIY Playbook's Casey Finn shares a quick, twice-a-year routine that can help extend the life of your garage door and prevent costly repairs down the line.

"We're going to do a little garage door maintenance," Finn said. "It's very quick and easy, and it's going to keep your garage door working well."

What you'll need:
Rag
Garage door lubricant (white lithium grease)
Ladder (if needed)

Step-by-step breakdown

Step 1: Inspect the door
Start by opening and closing your garage door. Listen closely for squeaks, grinding, or any jerky movement that could signal a problem.

Step 2: Clean the tracks
Wipe away any dirt or debris that could block the door's movement. Keeping the tracks clear helps everything run smoothly.

Step 3: Clean the sensors
Locate the photo-eye sensors near the bottom of the door and wipe them clean so the safety system can function properly.

Step 4: Lubricate moving parts
Spray hinges, rollers, springs, and other moving metal components with garage door lubricant or white lithium grease. Use a rag to catch drips and wipe away the excess.

One key tip from Finn: skip a common household product.
"I don't want you to use WD-40 for this," she said. "If you learn anything from this segment-don't use WD-40."

Step 5: Check weatherstripping and clean the door
Inspect the rubber seal at the bottom of the door for cracks or gaps. If it's worn, add it to your to-do list. While you're at it, give the door a quick clean if needed.

Important notes
-Your garage door is the largest moving object in your home
-Perform this maintenance twice a year
-Lubricate moving metal parts only - not the tracks
-Pay attention to new squeaks, grinding, or uneven movement
-Keep photo-eye sensors clean so the safety system works properly
-Check weatherstripping for wear and tear
-Call a professional for spring or cable repairs

If you keep up with this simple routine, you can help your garage door stay safe, quiet, and working properly year-round.
