4. The Winchester House - 4

Host Steve Thomas lends carpenter Charlie Silva a hand in slowly jacking up the second floor, then general contractor Tom Silva glues and bolts reinforcing LVLs to the damaged floor joists. Plumbing and heating expert Richard Trethewey arrives to drain the heating system and disconnect the old radiators. In the kitchen, homeowner Kim Whittemore and a friend take down the chimney brick by brick. The next day, some unwanted trees are cut ""up"" rather than cut down, as they are chain-sawed apart and lifted piece by piece out of the backyard with the help of a large crane.
