Things You'll Need:
- Ladder (6 foot)
- Pliers or Linemen (1 Pair)
- Screwdrivers (Philips Head and Standard)
- WD-40 (1 Can)
-
Step 1
Close the garage door. Make sure you have enough light to work with.
-
Step 2
Using a ladder, visually inspect both of the garage door tracks. The tracks keep the garage door rollers in line and in place. Make sure the lips of the tracks are not flattened or damaged. If so, bend the track inwards, back into place, with a pair of pliers or linemen.
-
Step 3
Visually inspect the rollers and their brackets. The rollers are, of course, the "wheels" that allow the door to move. Make sure the brackets holding the rollers are tight. They are typically screwed into the door and will only need a Philips head or standard screwdriver to tighten. This is the most common culprit in terms of sagging garage doors.
-
Step 4
Visually inspect the hinges between each section of the garage door. Loose or broken hinges are the second most common sagging culprit. They too can be tightened with a screwdriver. Damaged hinges must be replaced and can be found at any reputable hardware store.
-
Step 5
Once all the screws have been tightened, the roller brackets tightened, and any damaged hinges replaced, lubricate the rollers and track with a healthy dose of WD-40.
