A new front walk is put into place at the Winchester, Mass., colonial-revival while contractor Tom Silva measures storm windows. Inside, cabinetmaker Jeff Peavey shows off his kitchen cabinets, and plumbing-heating expert Richard Trethewey explains heating strategies for each floor of the house, including the basement. Meanwhile, carpenter Norm Abram visits a Connecticut firm that makes storm windows, and host Steve Thomas tours a suburban-Boston park known as Middlesex Fells Reservation. And on “Ask This Old House”: “Housecall” segments feature the removal of ivy covering a house and the replacement of a third-floor bathroom window.
