QUESTION:
I’m putting a new basement under my house. How can I make sure it’s done properly to prevent mould?
ANSWER:
When adding a new basement, the most critical factor in preventing mould is proper drainage and moisture control. A well-designed basement drainage system is essential—and not every contractor gets it right.
Always verify your contractor’s credentials, ask for references, and make sure they have proven experience with below-grade construction. Details like waterproofing methods, drainage layout, and ventilation can make the difference between a dry, healthy basement and years of costly problems.
There are also smart design decisions—like right-sizing mechanical systems—that can improve efficiency and save money long-term.
If you’d like guidance through these decisions, I’m happy to help you avoid expensive mistakes, future repairs, and unnecessary stress.

Question: “I’ve heard the city of Weyburn ( building code?) will not permit sheathing the exterior of your house in high-density foam. While it is added R value, do you think the vapor-tight foam locks condensation inside the exterior walls of the home?”
