144 - Tips for Young Builders with Tim Hill – Risinger Build

What does it really take to grow as a young builder today? Jake and Steve bring in Risinger Build’s Managing Partner, Tim Hill, for a fast-paced, experience-packed conversation full of practical advice for builders looking to level up their craft, business, and mindset.

Jake and Steve give Pete the boot for this one—and for good reason. Tim joins them to share real-world insights on everything from building capital and managing budgets to client communication, niche-building, and avoiding the projects that drain your time and sanity. Across the episode, there are a “baker’s dozen” takeaways that every young builder needs to hear.

143 - Venting Cathedral Roofs & 6-Sided Insulation Explained

A deep dive into cathedral roof design and insulation strategy. The team compares solid-sawn rafters vs. scissor trusses, smart vapor retarders vs. poly, and discusses optimal roof pitches. You’ll learn when to vent from the topside, from below, or go unvented entirely—and why those choices matter.
In the last 10 minutes, the crew unpacks one of building science’s trickiest topics: 6-sided containment of air-permeable insulation—and how it impacts attic R-values and energy performance.

142 - Sage Advice for Young Architects

Seriously? These 3 clowns are sages? The discussion includes how to select the "right” school. How much should a school include building science compared to learning it on the job? And what about even just the 4 control layers?  And all three of us stand squarely with Steve: if you want to design buildings, get out on the job site first, second, and last over the course of your prep and your years on the job. And then take what you learn at the site to improve the information transfer you accomplish with your drawings!

141- BUILDING SCIENCE NAIVETE? You heard it here first!

All of us in the industry have projects--likely early in our careers--that we just either cringe about or wonder how the heck we got away with that one? The boys wax nostalgic about stories of their naivety over the years, turning them into valuable lessons learned. Actual building topics include spray foam, sill sealer, combining blower door & IR imaging, slab-on-grade insulation, and rainscreens.

140 - Window Installation: Can We Do Better?

Installing windows is getting more, not less, complicated. Pete lobbies for a different, more durable, and simpler gasket installation of windows. Steve and Jake weigh in with their insights and challenges to what Pete is up to. And a bonus: with Steve and Jake's help, Pete creates a new word: "Poninions" (Pete crashed the words opinions and positions, and his "friends" just could not let it slide).

139 - Roof framing, thermal bridging, and Cold climate wall worries

The boys start with a really cool problem-solving involving a monopoly framing, big overhangs, and thermal bridging. And the follow-up is an excellent question from Western Canada regarding the use of ZIP sheathing with a Class I interior vapor retarder. It's a great discussion involving R-values, air barriers, vapor permeability (including all Classes of vapor retarders), wetting, and drying. Whew! Good thing that Steve had a "great" joke to close this one out...(gag).

138 - Finding a High-Performance Builder

If you can't find an experienced high-performance builder, then find a professional builder who is willing to listen and learn! And add in time and money in the budget for that listening and learning. The same can go for your architect. But as Steve says: "SOMEONE has to drive the bus. Put on your big boy pants and move your business to the next level."

137 - Another two-fer - Thermally-broken basement slab-to-Superior Wall panel connection AND exterior sump pumps

All 3 UBIP podcasters are fond of the Superior Wall System, but connecting the extended "foot" of the foundation wall panel to the basement slab is a bit tricky. But not for Steve, but of course. And while sump pumps OUTSIDE are a mystery to Pete, Jake & Steve walk Pete through it. And a bonus: using gravel to spread the structural load and better manage the water load. All that and a "joke" by Steve to-just-die-for...

136 - We Want More! Permanent Wood Foundations & Career Pivotal Moments

Once again, we drive wood into the ground, but only in the context of Permanent Wood Foundations. No surprise that this discussion is all about water & drainage. And some episodes ago, the boys each revealed pivotal moments in their careers in the building industry and wrapped up with a request for your pivotal moments. We got one, but what a doozy from our buddy Carl Seville of SK Collaborative. I think we might be done now (at least for a while) with PWF, but come on now: email us your pivotal moment in our industry!

134 - Another Double Feature - SIPs vs Stick-Frame & Thermal Degradation of Rigid Insulation

Whole bunch of reasons to consider SIP building systems BUT switching from stick-framing is not a walk in the park. But UnBuild It has a ton of experience with SIPs. Next up: Just how stable are the R-values of rigid insulations (the plastic ones with blowing agents) over time? The boys spend just the right amount of time on this on...(just could not resist that).

133 - Deep Dive on That Pesky Transition: Top-of-Foundation/Bottom-of-Above-Grade Wall

Should exterior above-grade wall sheathing or framing line up flush to the outside face of the foundation? Is sealing the bottom of the above-grade wall and foundation with a sill sealer product like Protecto Wrap Triple Guard a good idea? This sets off Jake, Steve, and Pete on balancing water protection, air sealing, and drying potential at this key transition and challenges for control layer continuity. Finally, Steve gets TMI with his sleeping arrangements with his wife...

132 - The Pre-Construction Process?

Plenty of reasons for the question mark: Pete wondered what this term really meant; Jake points out that for most of his career, he was not involved in this process as a builder; Steve gets pretty heated when this process does not include budget (at least a realistic budget...). Gem here from Steve: "70% of a home's budget is hardwired into the number of square feet."

131 - Two Q's: Isn't ZIP-R backwards? Shouldn't we rainscreen roofs as well as walls?

Two great questions on which the boys pontificate in fine
form. Yes, ZIP-R is "backwards" (rigid insulation interior to
structural sheathing) but that does not mean that it doesn't work; it
does, just differently. So why don't we typically rain screen roof
claddings? The short answer is it always costs more, regardless of the
type of roof cladding. But you know the saying: vent until you
can't...

130 - Two Qs: Job Site Safety & Garage Moisture Management

What could be more fun than yammering on about scary job site stories and just how confusing a space your garage can be? You listeners ask the damndest questions, so we just keep on cranking... Per usual, Steve closes us out with humor worthy of these two questions...

129 - A Crazy Space - Decks Over Garages (or worse) & Living Spaces

The advice starts with "don't ever do this" and then dives into the details for doing it right: slope, overhangs, pedestal systems, step-down from house to deck, and truck liners. Wait, what? Jake describes a long-past project involving a spray-on truck bed liner protective coating (and there actually ARE spray-on residential roof systems for decks—who knew?).

127 - Master Plumber Eric Aune Part II: How NOT to wait for hot water!

Eric Aune would make the perfect Marvel Superhero Plumber. With tank versus Tankless water heaters, multiple small tanks, and on-demand recirc systems, Eric brings real-world insight to all sorts of plumbing technologies and techniques. And of course, Steve closes the episode with a special look to his future.

126 - All Things Water Heating with Eric Aune

Eric provides Steve and Jake with a plumber's perspective on almost every residential, domestic hot water system available in the US. Stick around for terms like "cold water sandwich," "air-to-water," "CO2 refrigerant," and "recirc." It's absolutely gripping!

125 - Christine Williamson: From training building practitioners to teaching the next generation of architects

Jake spends time at Virginia Tech with Christine Williamson, a leading building professional who integrates building science and architecture. In her first year as an Assistant Professor of Architecture, Christine applies building science to architecture courses such as Environment and Building Systems I and II. In her own words about her new position,  Christine says, "Architecture education is, I think, a lot closer to more of a fine art program than maybe a lot of people realize. That is something I would like to change." 

Jake springs a pair of UnBuild It questions on Christine: how does ZIP-R work in terms of moisture control and the best way to configure a crawlspace.
