“Money turns to water.” In this episode, we sit down with Dave from Pro Clima (Technical Innovation Engineer) to talk about the real transition from being on the tools to quoting jobs, running projects, and trying to keep cash flow under control.

Dave’s story is a good one. He started as a carpenter, spent years in the trade, then went back to uni and completed a Bachelor of Applied Physics before landing at Pro Clima. That mix of site experience and building science makes him one of the most practical voices in the high performance building space, especially when it comes to building envelope design, condensation management, and the details that keep homes durable.

We get into the building details that keep failing across Australian housing: box gutters, flat roofs, balconies over living areas, and planter boxes. Different details, same problem. Waterproofing risk. Dave breaks down why these designs leak, why minimum compliance is not the same as good building, and what builders and designers can do earlier in the process to avoid expensive failures later.

We also take a look at the NCC (National Construction Code), DTS (Deemed to Satisfy), verification pathways, and why “compliant” does not always mean “safe” or “durable”. If you care about building quality, moisture control, airtightness, and building homes that actually last, this episode will give you practical language and a better framework for decision-making.
