Air Sealing Ottawa
Air sealing is the most cost-effective first step to a more comfortable, efficient home — it identifies and plugs the gaps, cracks, and openings that insulation alone can't address, stopping drafts and reducing heating and cooling costs year-round. Ottawa's wide temperature swings — from -30°C in January to +30°C in July — and older housing stock in neighborhoods like Westboro, the Glebe, and Orléans make insulation, air sealing, and moisture control high-value upgrades. Exposed bedrock in areas like Kanata and Stittsville also makes radon a real concern.

Air Sealing Ottawa — Common Questions
What is air sealing?
Air sealing is the process of identifying and plugging gaps, cracks, and openings in your home's envelope — the barrier between conditioned indoor air and the outside.
How do I know if my home needs air sealing?
Signs include drafts near windows or doors, uneven room temperatures, high energy bills, and visible gaps around outlets or light fixtures. A blower door test during our free assessment can precisely measure air leakage.
Does air sealing work with my existing insulation?
Yes! Air sealing and insulation work together. Sealing air leaks first and then insulating is the most effective approach to improving your home's efficiency.
Will air sealing make my home too airtight?
Modern air sealing is done carefully to maintain healthy indoor air quality. We ensure proper ventilation is in place so your home breathes safely while staying efficient.
