Winnipeg's Insulation Experts

At Lockport Insulation, our comprehensive approach transforms your home into a model of efficiency and comfort. First, we address air leakage by sealing all penetrations in the attic—light fixtures, plumbing stacks, and vents—preventing unwanted heat loss and moisture intrusion. This step protects your roof, walls, and living spaces from damage and mold, while improving indoor air quality.

Next, we balance ventilation based on Canada Building Code formulas, installing roof chutes, gable vents, and intake/exhaust systems that remove excess moisture and heat. Proper ventilation keeps ice dams from forming, extends shingle life, and maintains a healthy attic environment.

Finally, we add high‑quality cellulose insulation to achieve the desired R‑value, typically R‑50 or R‑60. The loose‑fill material is fire‑resistant, pest‑repellent, and environmentally friendly, providing superior thermal performance without the bulk of rigid boards. The result is lower utility bills, a quieter home, and a significant increase in property value.

Beyond attic work, we offer wall insulation, wall injection, and insulation removal services. Our wall injection technique refills older cavities with cellulose, eliminating dust, pollutants, and allergens while boosting R‑value. For homes undergoing exterior renovations, we conduct assessments and replace damaged insulation, vapor barriers, and sheathing, installing rain screens for enhanced protection. When moisture, mold, pests, or asbestos are present, our safe removal processes restore safety and comfort without disturbing the living space.

Every project begins with a free in‑home estimate and a personalized plan that maximizes Efficiency MB rebates—often covering up to half the cost. By partnering with Lockport Insulation, you invest in long‑term savings, increased comfort, and a healthier, more resilient home.
