rubble foundation
We have a rubble foundation that needs attention, cleaning and insulation. a wire brush will remove most of the loose material and scling. The question is what is the best way to insulate . The cost to foam is approx. $ 3,000 vrs the cost to insulate with a breathing material on the wall. either way we need studs and drywall. I think that we should leave the wall accessable for air flow to get rid of any moisture, so I am questioning the foam. Any thoughts?
