This Old House Key Art

This week on PBS’s home improvement show, “This Old House,” the team heads to Westford to tackle a trio of essential, if not exactly glamorous, tasks. Forget fancy finishes and designer kitchens; this episode is all about the nitty-gritty structural elements that make a house a home.

In “Westford: Septic, Stairs and Subs,” airing Thursday, April 24 at 8:00 PM ET, host Kevin O’Connor oversees the installation of a brand-new septic system. It’s a job that’s more critical than it sounds, and the episode will likely offer a detailed look at the process, demystifying a system most homeowners take for granted.

But the plumbing doesn’t stop there. The crew will also be tackling the rough plumbing work throughout the house, giving viewers a practical understanding of how the pipes fit together and the essential role they play. Plus, there’s the small matter of a fire-damaged staircase that needs repairing, a task requiring both precision and an understanding of historical construction methods.
