Master electrician Allen Gallant shows Kevin how he's going to update the recessed light fixtures and add new sconces over the mantel. Norm visits a factory in Londonderry, New Hampshire, to see how they're making and testing two types of windows for the project. Roger shows Kevin the infiltration system that is going to disperse the water from gutters into the ground.
