Homeowners Terry and Sima Maitland puzzle over exterior paint colors, settling on a pumpkin for the field and cream for the trim. They discuss a few details of the farmer's porch that may be reconsidered: a post up against the body of the main house, trim treatment along fascia, and a gutter. Inside, our host checks out a new central vacuum system, while the guys review the heating and cooling systems for the new addition: radiant baseboard downstairs and in the master bedroom, in-wall radiant tubing for mudroom, stairwell, and master bath. Preservation mason Steve Roy diagnoses the fireplaces on the first floor and decides that the chimney should be rebuilt from the roofline up. Finally, landscape contractor Roger Cook supervises hydroseeding of the lawn.
