Reliable Attic Insulation Services & Air Sealing Solutions in Dorval, QC

Our client in Dorval reached out due to significant concerns about the condition of his attic, which had gone uninspected for a long period. Upon scheduling a comprehensive inspection through our appointment center, our specialist visited the property. The inspection revealed excessive humidity and a noticeable odor, both symptoms of unaddressed air leakage. These air leaks were traced to junctions, including penetrations around the chimney, recessed lighting fixtures, and various service entry points for wiring and plumbing.

Unsealed air leaks in the attic significantly disrupt the thermal efficiency, causing heat loss during winter and heat gain in summer, leading to uncomfortable indoor climates. This thermal bypass not only increases the home's reliance on HVAC systems but also results in elevated energy consumption, reflected in higher Hydro bills. Additionally, insufficient insulation and unmanaged air leaks contribute to moisture buildup, which fosters mold growth, posing a risk to both the structure and air quality.

Upon contract approval, we initiated the remediation process:

Removal of existing insulation: This critical first step allows for the identification of all concealed air leakage points, particularly those masked by the old insulation.

Air sealing: Using industrial-grade ZypFoam, we meticulously sealed all air leak sources. This step is essential in establishing an effective air barrier to maintain thermal consistency and eliminate drafts.

Installation of high-performance insulation: We installed TruSoft cellulose insulation, applying 16'' to achieve an R60 thermal resistance. TruSoft's fire-retardant and mold-resistant properties make it a superior material for long-term energy efficiency and moisture control.

By upgrading to an R60 insulation level and sealing the attic air leaks, the thermal performance of the home improved drastically, reducing energy consumption and mitigating the risks associated with moisture. The client experienced immediate results in indoor comfort and anticipates long-term savings on heating and cooling costs.

The client expressed great satisfaction with the technical precision of the work and the professionalism of our team throughout the process.

Ms. Samoluk contacted Systèmes Éconergie because her attic had not been re-insulated for at least 10 years. She had started feeling some cold breezes in the house, which made the rooms less comfortable.

Our specialist went on site for the free inspection of the attic, and strongly recommended changing the insulation system .The fiberglass insulation was insufficient and got moldy in some places.

Our team of experts has completely reinsulated the attic. We removed the old wool, sealed all the gaps and wired the holes on the attic floor with a polyurethane foam. Finally we blew 16” of cellulose fibers to achieve an R60 value. Our client now can benefit from his comfortable home for many years to come.
