I think I'm posting this in the right place.
We are coming to the end of our home inspection period and the seller has agreed to "rebulid" the plenum. According to the inspections, the plenum has been in contact with the soil and the bottom has corroded away. My question is, can that be "rebuilt" or should we ask the seller to replace the plenum completely?
I would feel so much more confident if I knew this was a routine repair.
