Harry Clark Plumbing & Heating, Inc., based in Oakland, California, has a rich history that dates back to its founding in 1941 by Harry Clark. Initially starting as Grand Ave Plumbing, the company evolved and relocated to College Ave before finally settling on Piedmont Ave, where it was rebranded to its current name. The company has been a staple in the community for decades, providing reliable plumbing and heating services.
After Harry’s passing, Madeline Clark, his wife, took the reins of the company. With a strong background in plumbing rooted in her family's legacy, she became one of California's first licensed female plumbing contractors, proving that dedication and resilience can transcend gender barriers in the industry. In 1976, after years of successful leadership, she sold the company to Donald and Beverly Marshall, experienced professionals in the plumbing sector since 1952. They continued the tradition of quality service, training the next generation by hiring their son, Brad Marshall, in 1985.
As the company progressed, it changed hands within the Marshall family, with Don and Brad taking over in 1989. They further cemented their commitment to the community by purchasing a new building on Broadway in 1994 and expanding with another location in 2012. In a strategic decision in 2020, they split the company into two distinct entities: one focusing on plumbing and sewer services and the other on heating and air conditioning. Today, Harry Clark Plumbing & Heating continues to thrive under the guidance of the Marshall family, embodying the values of exceptional service and community dedication. As they look to the future, they aim to pass on their legacy to the next generation.
