I'm looking at the cost to change my crawl to a conditioned space. This is a 5,000 sq/ft 1 1/2 story house in west Tn. I haven't measured the first floor space yet but I would guess it at 2500 sq/ft. The house is only 5 yrs old. The crawl is only 30-36" tall and there is no water problems under the house. I know I'm having the stack affect going on because I have felt the cold air coming in on supper cold days. I can feel it most in the master bath around the tub. I think if I'm feeing it here as much as I am then it's coming in everywhere. The thing I need to figure is how do I figure at what price is it worth to correct? I was talking to a contractor that is a friend of mine and we were comparing utility bills. Our houses are about the same size but his has a conditioned basement and his bill was half the cost of mine. This just confirms what I'm thinking.
Your thoughts please?
