I'm about to condition my ~600 sq. ft crawlspace by removing existing batt insulation, spray foaming the rim joists, installing Thermax foam board on the foundation walls, and putting down 8 mil poly (half the floor is dirt, half concrete slab). I have gotten two quotes. One was $9,000 and one was $5,000. The $9k seems insanely high, and even the $5k seems just high.
When I had the house inspected before I bought it, my home inspector guessed it would cost about $2k to do this. (He recommended that I take the above steps.) So, I'm trying to figure out which one of us is smoking crack.. Does anyone even have a ballpark guess for this?
