How experts tackle structural decay and flood management in historic home renovations

This episode of This Old House demonstrates professional techniques for leveling sagging floors, framing new interior walls, and managing pest infestations. Beyond the construction site, the team explores the engineering history of the Charles River to understand regional flood control strategies.

The renovation process highlights practical solutions for common historic home issues. General contractor Tom Silva demonstrates how to correct a sagging kitchen floor from the basement, while master carpenter Norm Abram utilizes a systematic approach to framing by pre-assembling wall sections before installation. The team also addresses structural integrity by replacing termite-damaged sills and implementing eco-friendly pest control measures for carpenter ants.

The episode also shifts focus to environmental engineering. Plumbing and heating expert Richard Trethewey consults with Bill Gode, the Massachusetts State Director of Flood Control, to examine how the Charles River has been modified through major engineering projects, specifically the construction of three significant dams. This segment provides context on how large-scale infrastructure influences local landscapes and property protection.
