I just bought a house which has been converted from forced air to hot water baseboard heating. Someone removed all of the ducts, but left the register covers in all of the floors on the first floor. I want to remove these, but they all leave gaping holes into the basement.
My personal thought is to somehow fill the holes with wood and then put flooring on top of the patches. I'm handy, but I don't have the technical training to know what kind of wood to use, what size pieces to buy, screws/nails, etc. I'm confident I can do the work if I know what materials to get.
Has anybody done this sort of work before?
