A client contacted us after he removed the old existing insulation himself. He was asking us only to put fresh new insulation. As the attic was empty, we noticed the existence of mold spores, as well as some sources of air leaks. Thus, prior to blowing in our cellulose insulation, we managed to seal all the air leaks and remove all the mold spores before putting around 17 inches of our TruSoft cellulose insulation to reach the thermal value of R60. As a result, the attic was now very well insulated, which will increase the energy efficiency and the residential confort of the house.
