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.
Safety Inspections: Garage doors operate under a massive amount of tension. It’s the tension that makes a garage door work properly, but this tension can also pose a threat when the garage door is out of order. To ensure that your garage remains a safe place, we provide an annual, 14-point safety inspection. This can pinpoint problem areas before they spiral out of control and help you prevent costlier repairs after something goes wrong.
