Step 2: Check the tracks with a level to make sure they’re properly aligned. Horizontal tracks should slant slightly down toward the back of the garage; with roll-up doors, the vertical sections of track should be exactly plumb. Both tracks must be at the same height on the garage walls. If the tracks are not properly aligned, loosen but do not remove the screws or bolts that hold the mounting brackets, and tap the tracks carefully into position. Recheck the tracks with the level to make sure they’re in the right position; then tighten the screws or bolts at the mounting brackets.

Step 3: Clean the tracks with concentrated household cleaner to remove dirt and hardened grease. Clean the rollers thoroughly, and wipe both tracks and rollers dry. Find the garage doors Kirkland WA.
