0 Maria Snellville, GA on Feb 01, 2011 Like Clip this is the picture of the trim on the garage door that is rottening it isnt big can i just cut this out and put a new piece in. Like Clip 1 Comment Humphries Homes Decatur, GA Just go up about 6 inches from the existing rot and you should be good. Leave a small gap at the bottom so that it is not in direct contact with the concrete. NOTE: You can drag and drop your photos to reorder them Required Comment Saving...
