Clark Harry Plumbing & Heating Inc
Clark Harry Plumbing & Heating Inc., located in Oakland, CA, has a rich history that dates back to its inception as Grand Ave Plumbing by Harry Clark. After Harry’s passing, his wife Madeline took the reins, becoming one of the first women in California to hold a plumbing contractor license, and successfully led the company before passing it on to Donald and Beverly Marshall in 1976.
Continuing the legacy of community-focused service, the company was split into two entities in 2020: one specializing in plumbing and sewer services, and the other in heating and air conditioning. Today, two brothers operate the business from two buildings on Broadway, committed to delivering the highest quality products and services to their customers.
