We saw Insta-Insulation on Holmes on Homes so we thought they would be ridiculously overpriced like the other contractors they use on the show. But Insta-Insulations surprised us, the beat the other two quotes we had and their installation people were top notch! They even gave us some tips on finishing off our renovation. The result is that our attic is super air tight, no drafts at all. It is warm in the winter and it stays cooler then it used to be in the summer. The BASF product they use is amazing, I wish I could afford to do the whole house!
