Spray Foam Insulation Cornwall
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. Cornwall sits on the St. Lawrence River with cold, humid winters and many older brick and frame homes built before modern insulation standards. Drafts, high energy bills, and moisture are common — making spray foam, air sealing, and crawlspace encapsulation valuable upgrades for local homeowners.
