Introducing the creator of Block and Caulk

March 28, 2018

President

ESS Design Build, Austin, Texas

2017 Revenue: $2.5 million 

Biggest Achievement: In 2015, I came up with a system for air sealing homes called Block and Caulk. It’s the same amount of labor, but when it’s done you have the tightest home and no spray foam insulation. I’m educating people on how to build a very energy-efficient home in a simple fashion that can be taught and reproduced. The use of my system is becoming more and more common, and that is me leaving my mark all over the country.
