Episode Overview
After a month away from the site, the foundation is finally nearing completion, having been delayed by a three-week soil cleanup. With the intricate, 30-corner foundation walls in place, it's time to apply a proactive termite treatment under the slab. This innovative chemical allows termites to unknowingly enter the treated area, where they ultimately perish, and its effectiveness has been confirmed for over seven years. Before pouring the slab, the crew lays down a layer of 2-inch styrofoam insulation and installs a radiant heat system, which Richard insists on using in every slab, even if it’s not immediately activated. Later, our host visits a Florida home constructed by a major insurance company, sharing valuable tips on loss mitigation, including features like sprinklers and reinforced door jambs. Back at the site, the slab is poured, marking another significant step forward for homeowners Di and their project.
