What makes a great project manager in the residential construction world? Matt and Risinger Build business partner, Tim Hill, sit down to discuss what they’ve come to define as a GREAT project manager. Drawing on years of experience, they identify five essential qualities: 

1. Leadership
2. Collaboration
3. Communication
4. Work Ethic
5. People Management

Great project managers earn the respect of their teams through fairness, transparency, and deep knowledge. They must also collaborate effectively with everyone involved—from clients and design professionals to subcontractors and suppliers. Strong communication skills are key, with an emphasis on sharing updates early and often, especially when things go wrong. Weekly written progress reports, regular client meetings, and proactive problem-solving help keep projects on track. A solid work ethic is another cornerstone: successful PMs do whatever the project demands, even if that means working late or on weekends. They’re not just clocking hours—they’re taking ownership. People management, the fifth trait, ties everything together. PMs need emotional intelligence, adaptability, and the ability to influence and motivate a wide range of personalities. 

Matt and Tim also discuss the value of critical and logical thinking, which underpins all five qualities. They recommend using tools like PSP testing to evaluate applicants’ soft skills and cognitive strengths. Tune in for practical guidance for builders aiming to grow exceptional teams.

Matt welcomes fellow Build Expert, Travis Brungardt, back to the studio for a “back to basics” conversation: HVAC 101, which includes foundational concepts, practical advice, and common mistakes in residential HVAC systems. Emphasizing the importance of proper planning, they stress starting with accurate manual J load calculations to avoid outdated “rules of thumb” like sizing based solely on square footage. 

Matt & Travis also break down the crucial roles of manuals D (duct design), S (equipment selection), and T (terminations). Both champion rigid metal ductwork for optimal airflow, using minimal flex duct only at final connections to reduce noise. Also, they warn against unconditioned attic duct runs and advocate for dedicated return ducts in each major room to maintain balanced airflow and comfort. The conversation explores the pros and cons of two-stage and variable-speed systems, promotes ductless mini-splits for additions, and strongly advises against zone damper systems due to reliability issues.

They also highlight the importance of user education: set thermostats and forget them, avoid "fan on" mode, and design systems for future maintenance access. Matt and Travis remind builders that a well-designed and properly installed HVAC system not only improves energy efficiency but also delivers lasting comfort and better indoor air quality.

Matt and his business partner, Tim Hill, dive deep into the realities of profitability in the construction industry. Recorded in the brand-new Risinger Build studio, Matt & Tim share a candid conversation about the challenges general contractors, home builders, and remodelers face when it comes to profit margins, client expectations, and project planning. Despite the common misconception that builders are highly profitable, they reveal that average net profits hover around just 5–6%. This low margin—combined with high risk—requires smart planning, detailed pre-construction processes, and disciplined financial management to ensure long-term sustainability.

Matt and Tim stress the importance of transparency in pricing and standing firm on realistic budgets, even if it risks losing a job. They warn against chasing "portfolio projects" that look good on paper but lead to financial losses and client frustration. A major theme is the need for builders to carefully align with clients, architects, and budgets before contracts are signed to avoid scope creep and misaligned expectations.

Not only do Matt & Tim discuss the “what” and the “why” of profit margins but also share the “how” to manage profit and loss statements effectively, including separating direct costs, indirect costs, and overhead.

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.

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. Check out the first two episodes of Prairie Sun & Timber on thebuildshow.com.

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.

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. For expert coaching and funding, visit HighSpire.com.

This week on the Build Podcast, Matt welcomes Justin Pratt from Builders Firstsource (BFS) back to the ROCKWOOL studio to explore the future of home sales, particularly whether traditional model homes are obsolete. Rising construction costs and changing buyer expectations have made 3-D digital tools a cost-effective and efficient alternative.

With over 398 pre-vetted home plans at BLDRPlan.com, builders can license ready-to-build designs that integrate seamlessly with BFS’s advanced building technologies.

The Home Configure system from BFS allows builders to showcase homes digitally, enabling buyers to explore layouts, customize finishes, and visualize their homes in 3D—all without stepping into a physical model. This streamlines the sales process, eliminates costly last-minute changes, and speeds up construction. By integrating prefabrication and digital modeling, the BFS READY-FRAME® system has been proven to reduce build times by 40%.

What’s next from BFS? They are set to launch a real-time pricing module, similar to automotive “build & price” tools, allowing buyers to see accurate costs for their selections.

Matt is solo this week for an in-depth discussion on spray foam insulation, focusing on the differences between closed-cell and open-cell foam and the benefits of creating a conditioned attic space. Traditionally, HVAC systems and ductwork are placed in unconditioned attics in the South, leading to energy loss, duct leakage, and humidity issues. By using spray foam insulation at the roofline, homeowners can effectively seal and condition their attic, improving efficiency and reducing moisture problems.

Matt highlights Owens Corning Ultra-Pure Natural Polymers closed-cell spray foam as his preferred insulation choice, citing its high R-value (~R7 per inch), low VOC emissions, excellent air sealing, and moisture resistance. Unlike open-cell foam, which can allow vapor to pass through, closed-cell acts as a Class II vapor retarder, preventing moisture accumulation at the roof deck. This is crucial in humid climates where improper insulation can lead to condensation issues, a phenomenon known as "ping pong water" that can cause long-term damage to the roof structure.

For humidity control, Matt advises builders to install dehumidifiers or controlled air supply in conditioned attics to maintain proper moisture levels. He also stresses the importance of hiring experienced spray foam contractors, ensuring the correct thickness and installation quality.

Another key topic is roof durability and leak prevention. Matt recommends using full peel-and-stick underlayment beneath metal or tile roofs for long-term water protection. He debunks the myth that spray foam prevents leaks, explaining that small, intermittent leaks can go undetected, leading to hidden rot over time.

Tune in for everything you need to know (and more!) about spray foam insulation.
