Insulating a moldy attic in La Prairie, Qc

Problem

Our client, residing in La Prairie, contacted Systèmes Econergie due to continuous discomfort related to drafts in his house, despite the heating working constantly. Our specialist Houssem visited for a free inspection and estimation. He explained that a poorly insulated attic is most probably the cause of the residential discomfort. He identified some major problems: There was insufficient insulation, compromising the attic efficiency. From the other side, there were mold stains on the existing insulation and ceiling due to excessive moisture in the attic, which, in turn, resulted from unsealed air leaks in the attic. 

Solution

We started by removing the existing insulation, which was decayed due to mold, to facilitate the identification of all sources of air leaks in the attic. Using our excellent Mold X2 product, our team was able to eliminate all remaining mold stains. We sealed all areas with air leaks to ensure optimal sealing of the space. The sources of air leaks were numerous, such as ventilation ducts, attic access hatches, and holes for wires and pipes. We blew in our cellulose fiber insulation. This achieved a thermal value of R60, ensuring optimal insulation for the climate of this region in Quebec.
