Ron was the proprietor of Trethewey Bros. Inc., the family plumbing and heating business serving the Boston community since 1902.

Ron loved working on the show but was not comfortable with cameras, so he asked his 25 years old son, Richard to take over.

He has also appeared in ‘This Old House’ spin-off series, Ask This Old House and Inside This Old House.

Now, he is a licensed master and journeyman plumber in the Commonwealth of Massachusetts.

In 1990, he founded RST Inc., a manufacturer’s representative for several lines of plumbing and HVAC equipment.

He also serves on the editorial board of This Old House magazine, published by This Old House Ventures, Inc.

He has contributed to several books published by This Old House Books, including Complete Remodeling and The Homeowner's Manual.

Additionally, he also authored ‘This Old House Heating, Ventilation and Air Conditioning’ in 1994.

His sons, Evan Trethewey and Ross Trethewey are also involved in their father’s business and sometimes appear on ‘This Old House.’

Richard has an estimated net worth of $1.6 million.
