We had a home inspection done on a house we want to purchase and discovered that the home has no under house access. There is a poured concrete "grid" with 2 x 8 wooden floor joists resting on the concrete. This puts the floor joists only a couple inches up off the dirt ground and the subfloor about 10 inches from the dirt. The cooper water pipes are threaded under the joists and sit partially buried in the dirt. We were all dumbfounded. Can this situation be changed or worked with? Or should we run from this house as fast as we can?
