This Old House

Charlie and Tom Silva work in the attic, installing a hip beam and roof rafters to match the original roof. Downstairs, building scientist Joe Lstiburek discusses with Kevin O'Connor how insulating exterior walls can damage siding if energy flow isn't considered. Later, Mark McCullough brings in a stone cutter to cut through the original foundation, creating a garage door opening in the basement.

The team joins Charlie Silva for their new project in Westford, Massachusetts. They are introduced to homeowners who plan to lovingly restore the historic colonial that was damaged by fire. Kevin O'Connor tours the first floor while Tom Silva assesses the fire damage.

It's moving day in Ridgewood, as the renovation wraps up. Peter gives Kevin O'Connor a tour of the first floor while Kay gives Tom Silva a tour of the upstairs. In the basement Kay finds Richard Trethewey and Peter where Richard explains the new upgrades. Later, the homeowners and Jenn Nawada enjoy the new patio and water feature. Everyone joins them outside to thank Zack Dettmore and his crew.

Jenn Nawada meets tree care expert Matt Chase, who points out issues harming the Sugar Maple. In the basement, Richard Trethewey meets Kordian Rak, who discusses the new combo boiler heating both radiant and domestic water. Kays mother and Tom Silva cut tile for the pantry backsplash. Kevin O'Connor meets electrician Matthew Sczensy, who suggests a wireless light switch instead of rewiring.
