Mold Elimination and Perfect Attic Insulation in Sainte-Marthe-Sur-Le-Lac, Quebec
Challenge
A resident of Sainte-Marthe-sur-le-Lac, Quebec, contacted us after discovering the presence of several mold spores within his attic. The problem was not only affecting the indoor air quality of the house, but could also lead to long-term structural damage. Our specialist's free inspection revealed that the issue was caused by inadequate insulation and numerous unsealed air infiltrations.
The amount of insulation in the attic was well below the recommended norms for our climate, which contributed to heat loss. In addition, the lack of airtightness allowed warm, moist air to infiltrate the attic, thus increasing humidity levels and creating an environment conducive to mold growth. The result was incarnated by black stains on the wood as well as on the existing insulation.
Solution
To remedy the situation, our team implemented an approach aimed at optimizing the attic's thermal insulation:
Removing the old insulation
Existing, deteriorated and contaminated insulation was removed to identify all the hidden sources of air leakage.
Treatment with Mold-X2
The attic surfaces, including the floor and roof soffit, were treated with Mold-X2. This treatment eliminates mold stains and prevents their recurrence.
Air Sealing work
We then sealed all sources of air leakage, including ventilation ducts, space around the chimney, and openings created for cables and pipes.
Installation of cellulose fiber insulation
A new, uniform layer of cellulose fiber was blown in to achieve a thermal resistance of R60. This type of insulation is not only high-performance, but also environmentally friendly and fireproof.
