In this episode:

Plumbing and Heating Expert Richard Trethewey tells all about how his career as a plumber started. As a 4th generation owner of a successful plumbing and heating company, Richard knew what he would do for a career very early on. He would draw pictures of himself fixing sinks and making plumbing repairs in school.

While working for his father’s business, Richard explains the company received a call from a public television channel asking if they’d be interested in appearing on the show. Despite not having money to offer, Richard’s father saw it as an opportunity to pay their success forward. While his father might not have been the most comfortable TV personality, Richard’s calm demeanor on screen made him a natural fit for This Old House. Years later, no one better fit for the role on Ask This Old House than Richard.

Next, we meet tech expert Ross Tretheway and host Kevin O’Connor back at the shop to talk about Smart Thermostats. As Kevin asks the hottest questions on the topic, Ross explains the features, cost, savings, and convenience that a smart thermostat can offer to almost any home. Ross describes how far thermostats have come to Kevin, and even some of the most up-to-date, cutting-edge features that today’s thermostats have to offer.

After the smart thermostat conversation, Kevin meets master electrician Heath Eastman for a lesson on switch legs. Heath explains that many homeowners have a switch in their home that doesn’t appear to control anything. Heath tells us that, in many cases, these phantom switches are intended to control an outlet, but that renovation and repairs along the way could be the cause of the missing functionality. After explaining why that is, Heath shows Kevin how to restore the switch function to the affected outlet.

Finally, general contractor Tom Silva supports a homeowner suffering under a rotted porch post. Tom and the homeowner dig into the rotten post base to find the issue and then get to work removing the affected wood. Next, Tom shows the homeowner how to mill new components from a recycled, water-resistant material before putting everything back together for caulk and paint.
