Company History

The company grew from a single-truck operation into a small fleet over 15 years. Early work focused on older East Bay homes with galvanized pipes and aging sewer laterals. Seeing a steady need for trenchless options and camera inspections, the business invested in sewer video equipment and jetting systems to reduce disruption for customers.

Over time Calmo's added commercial service capability and expanded the service area to include both inland and coastal Bay Area communities.
