Attic Insulation - Costco
I am looking to get my attic insulation updated and asked costco and a guy came and gave me an estimate of $1.25/ square foot. He said they will install or extend the baffles. They will use blown in fibreglass for R-50 to 18 inches. Right now it is only upto 5 inches. (So they will add another 13 inches). There is apparently a lifetime warranty as in if the insulation settles to less than 15 inches they will do it again or something along those line. Made a comment about the attic hatch and how that is wasting energy and they will upgrade it.
Good quote and go ahead or ask some other person.
