A year after California’s worst wildfire, the people of Paradise are still clearing the devastation where about 90% of homes were lost. Kevin, Tom, and Richard meet three families determined to rebuild according to the wildland urban interface codes. Nathan travels to a Sears kit house in Richmond, Virginia to tighten an old, loose stair railing; Mauro demonstrates how to strip paint off of old door hardware; Heath explains the uses and purposes of different types of electrical boxes; Richard replaces an old thermostat with a smart thermostat without replacing the original two wires in the wall.
