Applying Building Science to Ottawa’s Historic & Modern Homes

A beautiful home is only as good as the structure behind the walls. Denys draws on the research and principles of the Building Science Corporation (BSC) to ensure your renovation is built to last in Ottawa’s extreme climate.

“Building Science” is the study of how heat, air, and moisture move through a building. We apply this knowledge to:

Moisture Control: Ensuring your new kitchen or bathroom is properly vented and sealed.
Historic Retrofits: We specialize in the sensitive restoration of Ottawa’s older homes, applying science to ensure old structures breathe correctly.
Structural Integrity: Using materials and methods that prioritize longevity.
