Can you straighten a garage door?

Yes, you can straighten a garage door that is bent, warped, or dented depending on extent of damage, door material, and whether tracks also bent, though severe damage may require panel or full door replacement. For minor dents in steel garage door panels caused by car bump or basketball, you can straighten by tapping dent from inside with rubber mallet, using block of wood behind dent for support, and using auto body filler for small creases, then painting. For aluminum doors that are lightly bent, you can gently push panel back with hands, but aluminum creases easily. For tracks that are bent causing door to be crooked, you can straighten vertical tracks by loosening mounting bolts and tapping track back to plumb with rubber mallet, then tightening bolts, or using pliers to open track channel if rollers popped out. However, if door panels are severely bent, creased, or folded, straightening may weaken metal and door may not seal properly, so replacing single panel costing 250 to 800 dollars or full door costing 800 to 2500 dollars is better. Wood doors that are warped from moisture may be straightened by adjusting hinges, but often need replacement if warped badly. If door is off track due to bent tracks, professional track straightening costs 150 to 400 dollars. Always disconnect opener before straightening and wear gloves, as door heavy.
