We visit the island of Nantucket, where architect Ann Beha's firm is expanding and renovated the historic Atheneum, the town library. She agrees to help out in Salem. In Salem, the crew erects aluminum pump jack staging - a safe and efficient system, especially when many trades will be working on the exterior. We tour a couple of paint jobs with painting contractor Mike McManus and asks him to squeeze our house into his schedule.The guys finish reglazing the old window sash, using old-fashioned mouth-blown restoration glass. In the basement, Richard Trethewey points out an inefficient electric water heater that currently handles both sides of the house, and an oil heater that could use some tuning up. Our master carpenter points out ""cooked,"" degraded old clapboards on the upper third of the building and recommends replacing them.
