Building CIRS-aware, mold-resistant homes with Special Guest Brian Tinker

In this CIRS Group Podcast episode, hosts Jacie and Barbara interview Brian Tinker, founder of Breathe Well Homes and a master builder with 30+ years of experience, whose work became personal after his wife’s CIRS diagnosis revealed their home’s role in her illness. Brian explains how moisture control is the core issue behind mold problems and why modern “tighter” energy codes can create sick homes without proper ventilation. He highlights common high-risk materials and methods (e.g., OSB, MDF, spray foam off-gassing, flex ducting, traditional grout), shares practical strategies for moisture management, wall assemblies that can dry, and using ERV/HRV systems to keep homes breathing. He discusses cost increases (about 35–45%), his course and consultations, remote build guidance, and his newer Breathe Well Vans concept, plus interest in manufactured homes for faster, lower-cost options.
