From his early years Richard witnessed his father working in the sphere of plumbing and heating, so learnt a lot watching his dad developing his business.


Richard started his career as a member of his father’s company, Trethewey Brothers, Inc. He’s a registered master plumber, and works both on the TV show series “This Old House” and as a hired plumber and  Heating, Ventilation, & Air Conditioning (HVAC) specialist. Richard left his father and uncle’s company in 1990, to launch his own, which he called RST, Inc. The company does everything related to HVAC equipment, plumbing and complete pipe systems installation. The company has its office registered in Westwood, Massachusetts, having nine employees, including Richard himself.

During his long career Richard has been invited onto such TV shows as “Late Night with Jimmy Fallon” (once in 2010 and twice in 2012), “The Tonight Show Starring Jimmy Fallon” (once in 2015 and again in 2017), in which he shared his experience of starring in the “This Old House” house improvement series.

This Old House

Launched in 1979, the franchise “This Old House” became one of the most popular house improvement series, having 40 seasons on WGBH-TV – in 2019 the show was obtained by WETA-TV. During its history the show won 17 Emmy awards and was nominated more than 80 times for many others.

Focused on renovating old houses, the series revealed many useful tips for those who decided to make changes in their houses themselves, with their own hands. As the program attracted a larger and larger audience, the franchise expanded, and WGBH-TV launched two more similar shows: “Ask This Old House” and “Inside This Old House”. Richard Trethewey appeared in all sister shows of the franchise.

“Ask This Old House”

Richard became a member of the regular cast for “Ask This Old House” along with his colleagues Roger Cook, Tom Silva and Kevin O’Connor, appearing as the host of the show. “Set near Boston, the experts answer questions on home improvement from readers of the “This Old House” magazine, and from the viewers of the show.

Some of them are even visited by the hosts of the show, getting practical analysis on their issue and some assistance in solving their problem. Kevin O’Connor participates in some of such episodes, helping the workers to do the task.

“Inside This Old House”

The show that aired from 2003 to 2004 was pretty much the same as “Ask This Old House”, the difference being that it concentrated on one theme, for example, landscaping, heating, installing windows, etc., and discussed it during the whole episode, giving comprehensive answers to all the questions related to the chosen topic. Richard, as usual, acted as the expert on plumbing, heating and air conditioning.

“This Old House: Trade School”

They say, ‘keep a dress long enough and it will come back in style’. Well, it turned out to be true for the show “This Old House”, as in 2017 the show spawned another spin-off with the same old hosts, including Richard Trethewey, Norm Abram, Roger Cook and Tom Silva, who discuss the same things related to the house improvement process, comparing their previous experience and modern day solutions. The spin-off is aired by the CW network.

Richard has been married to Christine for more than 20 years, and they’ve welcomed two sons: Ross and Evan, who are both starring in the show “Ask This Old House”.

Appearance, clothing style

Thus, he shared the photo of him standing in the cellar of the house he improved in terms of the show “This Old House”, and the ceiling was way too low for him: ‘There are many things I will miss about our fabulous Jamestown project; the original basement height is not one of them. I’m just too tall’, Richard wrote in his tweet.
