The side door of my garage is a 32 x 80 wood door, and there's no storm door to protect it from the weather. So the bottom has rotted out, and in one picture you can see some ripples in the upper part which may just be paint - not sure about that yet.
Anyway, I wondered if I could set my saw to a depth of maybe 3/16 inch and saw across roughly where the tape residue is shown in the pictures, and glue in a placement piece of wood. Then I would fill with some kind of filler from the bottom to fill any void, then finish with another strip of new wood on the bottom. Then finish off with heavy duty primer and several coats of paint.
It appears the only practical alternative is a prehung metal door which Home Despot will install for me for around $400. Of course they would also sell me a replacment wood door, with all the routing done and holes drilled per my measurements, for about $150 plus delivery, but, you know, if I'm gonna install a new door, I think I'd rather it not be a wood door.
Well what guidance would you give me about this? Is it silly to try to "repair" the existing door?
Thanks for any comments or suggestions.
