This Old House

The garage is nearly complete and fitted with trim that has been primed before construction. Our host and Mary-Van discuss insulation in the garage ceiling and the wall that meets the kitchen. Our master carpenter and general contractor install a low-maintenance, vinyl-clad window that has been adapted to make it more appropriate to a 1800s house. Then our host meets with security specialist Don Martini to learn more about interior and exterior motion detection systems, as well as reprogrammable alarm access code for bed and breakfast guests. He then meets up with our master carpenter on the roof where he's installed a skylight. Richard Trethewey debates the merits of different heating and cooling systems, including gas-fried furnaces, radiant-style baseboard heating, heat exchangers, and low-noise air conditioning units.
