Spray Foam Insulation Ottawa
Spray foam insulation is one of the highest-ROI upgrades for homes in the Ottawa Valley and Outaouais — it expands to seal every gap and insulate in one step, cutting energy bills, eliminating cold drafts, and strengthening your home's building envelope. 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.
