Tom shows Norm the progress on the approved dormer and how he's waterproofing its low slope roof.
Richard stops by the Charlestown Navy Yard to see a special guest arrive - the last wooden whaling ship in the world, the Charles W. Morgan, built c.1840. Tom shows Norm the progress on the approved dormer and how he's waterproofing its low slope roof. Inside, insulation is in and wallboard is going up. Out back, mason Mark McCullough installs a reclaimed brick veneer on the new kitchen bump out. Kevin checks on the kitchen design details, and Norm and Tom replace the fake shutters with operable shutters made of durable fiberglass and PVC. In the second half of the hour, on ASK THIS OLD HOUSE, the guys tackle practical solutions for drought. Richard and Kevin are at Lake Mead, the largest reservoir in the country, that's only at 40 percent capacity. Roger visits Las Vegas to replace a water-guzzling lawn with a desert appropriate alternative. Kevin meets with meteorologist Jim Cantore to hear cautionary tales from the front lines of the drought. And Richard travels to San Francisco to replace an old-fashioned toilet with a new "water sense" solution.
