Mold Prevention & Indoor Air Quality (Part 2)

It’s an IAQ Deep Dive…part two! Matt welcomes Sean Harris back to the studio to continue their discussion indoor air quality improvements for existing homes, focusing on mold prevention, HVAC upgrades, filtration, and dehumidification—especially in hot, humid climates like Texas. Sean emphasizes that mold issues often stem from leaky ductwork in unconditioned spaces, poor ventilation, and high humidity, leading to compromised air quality. Instead of cleaning mold, he recommends removing contaminated materials and improving source control.For HVAC systems, Sean suggests keeping ductwork in conditioned space, using MERV 13+ filters, and installing a ventilating dehumidifier to maintain humidity below 50%. He warns against running HVAC fans continuously, as this can pull humid air into the system, worsening mold issues. He also recommends in-room HEPA filtration (isuch as IQAir or Austin Air) over whole-home air purifiers.They discuss (and advise against) gimmicky air purification methods like UV lights and ionizers, which can create harmful byproducts. Instead, homeowners should monitor IAQ with smart sensors, track humidity, and optimize their home’s ventilation and filtration. Sean emphasizes "optimization over maximization"—cost-effective solutions like air sealing, replacing moldy ductwork, and using high-quality air filters rather than full HVAC overhauls.Both Matt & Sean encourage homeowners to prioritize practical, science-backed IAQ improvements for a healthier living environment.Thank you to episode sponsor Mbrico.

Prairie Sun & Timber

Matt welcomes fellow Build Expert, Travis Brungardt, to discuss the brand-new Build Original Series® Prairie Sun & Timber, which follows Travis as he builds a hybrid high-performance home blending Structural Insulated Panels (SIPs) and traditional framing. Travis outlines the project, noting that the upper level utilizes SIPs for insulation and strength, while the walkout basement level is conventionally framed with ZIP-R9 panels for flexibility. Throughout the series (and build itself), a key focus is air-sealing and moisture control. To prevent common SIPs failures like ridge rot, Travis applied PROSOCO Cat 5, a liquid-applied WRB, continuously from foundation to ridge, ensuring an airtight and waterproof structure. Matt & Travis discuss SIPs challenges, particularly running electrical wiring. Instead of the traditional method of melting wire chases, Travis framed a service cavity inside the walls, making installations easier. Matt and Travis emphasize the benefits of hybrid construction’s, proper air-sealing techniques, and ways to maximize performance while maintaining flexibility.

Mold Prevention & Indoor Air Quality in New Construction

Matt welcomes indoor air quality (IAQ) expert Sean Harris to explore mold prevention strategies for new construction. They discuss key building science principles, including air sealing, moisture management, and proper dehumidification to prevent mold growth in hot, humid climates like Texas. Sean emphasizes the importance of moving ductwork into conditioned spaces, using AeroBarrier and AeroSeal technology, and installing dedicated dehumidifiers to control humidity. He reveals that 90% of the 140 homes he inspected in 2024 had mold in the ductwork, even in new homes, due to poor moisture control. Sean recommends dedicated return and supply duct configurations for dehumidifiers and suggests a separate attic dehumidifier for homes with spray foam insulation. They also cover air quality monitoring, humidity control strategies, and redundancy for long-term performance.Thank you to episode sponsor Allura.

Building Generational Wealth, Literally

Matt interviews Paul Atherton, CEO of High Spire, about how builders can create generational wealth by leveraging their construction businesses for real estate development. Most builders sell their companies for 1-2x earnings, which isn’t enough to pass down wealth. Instead, Paul outlines three wealth-building pillars: operating a profitable business, investing in real estate, and adding value to assets.Builders have a competitive edge in real estate because they understand construction costs, materials, and labor, allowing them to budget more accurately than traditional developers. We can invest in land development, adaptive reuse projects, and value-add properties, turning older commercial spaces into high-yield investments. Paul stresses the importance of cap rates, IRR (Internal Rate of Return), and strategic financing; he recommends builders aim for 25% IRR on projects and seek off-market deals.For those new to investing, Paul advises strengthening branding and marketing, setting anti-goals to maintain work-life balance, and networking with commercial brokers and private investors. Builders should analyze 20 real estate deals per month to understand market trends. While High Spire offers capital investment opportunities, the goal is to help builders become self-sufficient real estate investors.With real estate offering long-term appreciation and cash flow, builders who reinvest wisely can secure financial freedom for future generations.

Slab vs. Crawlspaces

Matt does a deep dive into foundations and why one foundation might be a better choice than another, depending on your location.Many foundation styles came about because of frost-line differences. Northern builders might have a 3-foot frost line, which means it's necessary to dig below the frost line to avoid freeze-to-thaw issues in the wintertime. In other parts of the country, there might be a 1-foot frost line so a crawlspace makes the most sense. Finally, in the South and parts of the country with almost no freeze-to-thaw issues, slab on grade works great with a foundation embedded 12 - 18 inches into the existing soil.Matt considers how a foundation should be done when keeping ducts inside the conditioned space of a home. He focuses on crawlspaces versus slab on grade, with an emphasis on HVAC systems inside the conditioned envelope.Find Matt and The Build Show on the web:Build Show Videos: https://buildshownetwork.com/go/mattrisingerInstagram: @risingerbuild and @thebuildshowTikTok: @thebuildshowYouTube channel: https://www.youtube.com/@buildshowWebsite: https://risingerbuild.com/ and https://buildshownetwork.com/Don't miss a single episode of Build Show content.
