Our Story

In 2008 cofounders Brian Holtzman and Josh Johnson decided to transform their expertise in construction and real estate into a company that would offer the highest level of insulation services. The result was Eco Tec Insulation, based in Skokie, IL, which gained a reputation for quality insulation across the Chicagoland area. The company grew quickly and expanded its reach to include much of the area around southern Lake Michigan. Eco Tec has installed insulation in over four thousand homes, from small projects like bathroom remodels to major thirty thousand square foot homes. We have also worked with some of the most recognizable brands in the world including McDonald’s, CVS, Trader Joe’s, and many more.
