Drilling begins on a geothermal system.  Norm visits first-period homes.  Kevin tours a factory where the stairs and panels are built.  On the North Shore, he learns of a new technology to seal ductwork.

Kevin helps fit the cabinets.  Work starts on the driveway.  Granite is used for a patio.  The den gets wainscoting.  The homeowners select interior paint colors.  Erik installs the factory-made staircase.
