This Old House (1979) : 15x2

The asbestos removal crew begins to strip the house of shingles, under the watchful eye of a state official. As a prelude, our master carpenter visits a lab to confirm that the shingles contain asbestos, while our host meets a doctor who confirms the health dangers of the fiber. Back at the house, the crew sets up pump-jack staging, and the Gallants talk about the estimate ($91,000) versus what they can afford ($80,000).
