This Old House - Season 20 Episode 5 The Watertown House - 5
5.60 30 minutes The landscape work begins with landscaper Roger Cook and arborist Matt Foti marking trees slated for pruning or renoval and Matt's crew relieving the yard of some of its overgrown burden. Inside, the crew begins to rebuild the old oak staircase in the center of the building while mason Lenny Belliveau assesses the state of the flues with the help of a tiny ""lipstick"" camera. Atop the scaffolding, we learn how he has rebuilt the chimneys from the roof up, copying the corbelled and decorated originals.
