We live in a 2 story log house the main beam is rotted and 70% gone from termite damage. Can this be replaced, as the other floor joists are notched in to the main beam?
Hard to say without seeing it, but you may have to put two new beams in, one on each side of the existing one to support the joist. Call Ryan at 877-788-5647 for more answers. They do all of the structural work.
