In this episode of the Build Better Homes Podcast, hosts Royal Mortier and John O’Shea sit down with Nate McIntyre, Building Envelope Specialist and founder of CS Forensics, to break down how air, water, and material compatibility affect the long-term performance of homes and buildings.

Nate shares two decades of experience in construction forensics, uncovering how small oversights like improper flashing, insulation placement, or poor ventilation can lead to costly failures down the line.

From leaky attics and wet walls to how technology like 3D modeling and infrared scanning is changing inspections, this episode brings building science to life through real stories, practical advice, and a few hilarious moments (yes, even cat pee makes an appearance).

• The evolution of building science and moisture management
• How 3D modeling, Matterport, and laser scanning are changing inspections
• Common causes of air and water intrusion and how to prevent them
• The difference between design errors and installation errors
• How energy codes and climate affect building materials
• The importance of QA/QC and maintenance in preventing defects
• Real-world stories from construction defect cases (and some you won’t believe)

It’s not just about building tighter, it’s about building smarter. Understanding how materials, moisture, and air movement interact is key to preventing the hidden problems that cost builders time, money, and reputation.
