This Old House - Season 26 Episode 13

Kevin opens the show in Concord, Massachusetts, where dozens of stately elm trees once lined Main Street - until Dutch Elm disease nearly destroyed them all. At the project house, elm tree specialist Roger Holloway plants two three-inch caliper Princeton Elms - a disease-resistant cultivar that is helping return the elm to the American landscape. Well contractor David Haynes begins prospecting for water in the side yard, while master electrician Allen Gallant shows Norm the challenge he's facing with wiring both the SIPs and the timberframe barn. Lighting designer Susan Arnold shows Kevin some creative lighting solutions at another renovated barn in Reading, Massachusetts. Tom installs pre-finished cedar single panels that go up six times faster than individual shingles and carry a 35-year warranty. As darkness falls, the new well is already 200 feet deep, and counting.
