Grateful for how HCP made my full sewer lateral replacement easy and breezy. I needed extensive documentation for reimbursement purposes, and their staff was quick and responsive. Thanks all!

Harry Clark Plumbing & Heating, based in Oakland, CA, has a rich history that began with Harry Clark, who founded Grand Ave Plumbing in the early 1940s. After his passing, his wife, Madeline, became one of the first licensed female plumbing contractors in California, continuing the legacy of quality service in the community.
In 1976, the company was passed on to Donald and Beverly Marshall, who upheld the tradition of local plumbing service. Today, it operates as two distinct companies—one focusing on plumbing and sewer services and the other on heating and air conditioning—while remaining committed to providing exceptional products and services to their customers.
