Attic Insulation & Air Sealing Services in Lachute, QC

When a homeowner in Gore noticed that his attic was suffering from moisture, mold, sagging insulation, and drafts, he needed a solution to restore stable thermal comfort, reduce his heating bills, and protect his home from moisture problems. At Systèmes Éconergie, we removed the contaminated insulation, treated the affected areas, and applied complete caulking to eliminate all air leaks. We then installed our dense, high-performance TruSoft cellulose blown insulation, which fills all gaps and provides a uniform thermal barrier while resisting moisture and mold. The attic is now dry, healthy, and well protected, the interior temperature is stable, and the home enjoys lasting energy efficiency without the risk of mold returning.

In Lachute, the owner of this house was facing a classic problem: his attic was equipped with old, inefficient insulation, allowing warm air to escape and causing significant heat loss and high heating bills. The situation also created cold spots inside, making some rooms uncomfortable in winter. To solve these problems, our Systèmes Éconergie team removed the worn insulation, cleaned the attic, and carefully caulked all air leaks, including crawl spaces, access hatches, and ducts. We then blew in our TruSoft cellulose, an eco-friendly, high-performance insulation that provides consistent thermal insulation, optimal airtightness, and lasting energy efficiency. Thanks to this comprehensive intervention, the attic has been transformed: the house retains heat better, indoor comfort has improved, air quality has been preserved, and energy savings are significant. This experience perfectly illustrates how professional attic insulation in Lachute, combined with precise caulking and the use of TruSoft, can transform a home, reduce heating costs, and provide lasting comfort for its occupants.
