Early Life and Background: Age and Roots of a Plumbing Prodigy
Born on September 16, 1956, in Dedham, Massachusetts, Richard Trethewey’s age of 69 reflects a lifetime dedicated to plumbing and home improvement. Growing up in a family of plumbers, Richard inherited a passion for the trade from his father, Ron, and great-grandfather, Harry, who founded Trethewey Brothers in 1902. His early exposure to the family business shaped his expertise, starting with sweeping floors at age 12 and progressing to apprentice roles. This hands-on experience, coupled with his American nationality and Caucasian heritage, grounded him in a tradition of craftsmanship that he later brought to television.

After his father’s brief stint, Richard took the reins in 1980, becoming a mainstay for over 940 episodes across This Old House, Ask This Old House, and This Old House: Trade School. His ability to explain complex plumbing and HVAC systems in relatable terms made him a fan favorite.

As vice president, he has overseen innovative projects, including sustainable heating systems. A 2023 interview with Fine Homebuilding revealed Richard’s advocacy for eco-friendly technologies, such as heat pumps, which he predicts will dominate home heating by 2030. His company’s focus on renewable energy aligns with industry trends, adding a unique angle to his professional legacy.
