A garage door is typically the largest moving object in a home. Regular seasonal maintenance is essential to keep it operating quietly, safely, and reliably for years to come. By performing a few simple inspections and lubrication tasks every six months, you can prevent costly emergency repair calls and extend the lifespan of your opener and springs.
1. Visual Inspection of Hardware
Begin by checking all the moving parts of your garage door system. Look closely at the metal tracks for any dents, bends, or obstructions. Inspect the rollers for signs of wear, such as chipped edges or worn-out bearings. Check the lift cables running from the bottom brackets to the drums at the top—if you see any fraying, corrosion, or loose strands, do not touch them. High-tension cables should only be adjusted by a trained professional.
2. Proper Lubrication Technique
Proper lubrication reduces friction and noise, saving wear and tear on the opener motor. Use a high-quality silicone or lithium grease spray, and avoid heavy WD-40, which can attract dust and grime. Apply a light coat of spray to the roller bearings, track hinges, and spring coils. Wipe away any excess oil to prevent dripping.
3. Testing Balance and Safety Sensors
To test the balance, pull the red emergency release cord to disconnect the door from the opener. Lift the door manually to about waist height. A well-balanced door should stay in place or drift only slightly. If it slams shut or shoots upward, the spring tension is incorrect and needs adjustment. Finally, test the safety photo-eyes by placing an object in the door's path while closing—the door should instantly reverse.
