Harry Clark Plumbing and Heating Inc. started as a plumbing service company called Grand Ave. Plumbing in 1946. The company, led by Harry Clark, moved to Piedmont Ave. and changed the name to "Harry Clark Plumbing." Harry, along with his wife Madeline, ran a successful neighborhood plumbing company for many years. After he passed away, Madeline realized that she was not ready to retire or sell. On top of her experience working with her husband, she came from a family of plumbers and had worked with her father when growing up, so she decided to take over the business herself. She applied and succeeded in becoming a California licensed plumbing contractor: one of the first in the state!

In 1976 Mrs. Clark was finally ready to retire. She found Donald and Beverly Marshall, who had worked in the industry since 1952, to buy the company. Donald and Beverly continued the tradition of the local plumbing company, specializing in service for the Bay Area. They hired their youngest son Brad Marshall, a union-trained journeyman, in 1985. By 1989 Donald and Beverly were ready to retire. They sold the company to their two sons, Brad and Don Marshall.

Today, Harry Clark Plumbing and Heating Inc. retains its roots as a specialized air conditioning, heating and plumbing service company. We have expanded our service base to include sewer repair and replacement, as well as heating and air conditioning service and installation.
