This Old House Hour

Tom marries the addition's new roof to the old by graduating the rafters. Architect David Whitney explains how just 200 additional square feet will transform this house. Masonry repairs with a new mortar additive provide a waterproofing solution for the fieldstone basement. Roger tours the Italianate Garden at Elm Bank; Norm and Tom perform surgery to re-open a door in the foyer. In the second half of the hour, on ASK THIS OLD HOUSE, Richard visits Charlotte, North Carolina, to install a whole-house humidifier. Kevin and electrician Scott Caron install hardwired smoke and carbon monoxide detectors for a young family in Indianapolis. Tom shows how to remove stripped screws. And the guys ask, "What is it?"
