Contractor using concrete over some kind of metal mesh to ceiling in 1949 single family home . Originally had plywood (not drywall and room was an add-on), which came down due to rotted wood beams underneath. He replaced some beams, added the mesh, is troweling in concrete. I don't like the looks of it so far and am worried. No other room in the house has concrete ceiling.
For what it's worth, the added on ceiling was surrounding by concrete - just not in the center of the ceiling. But surrounding walls and frame of center is concrete.
Did I make a big mistake? Should I pay and have it all removed and drywall put up? Please help...this is new territory for me...:confused::
