Star’s Janitorial Services of Concord, California
Family-owned commercial cleaning since 2012
Star’s Janitorial Services is a family owned and operated commercial cleaning company headquartered in Concord, California. Since 2012, we have cleaned offices, medical facilities, warehouses, and residential communities across the East Bay and Contra Costa County.
The company was founded in 2012 by Maria M. Hernandez, Founder and CEO, who brought more than 20 years of facility-maintenance experience to a single mission: give every client a clean, healthy, well-cared-for environment. Today the business is a true mother-and-daughter operation. Maria’s daughter, Briana Cruz, Director of Operations & Business Development, runs client communication and account satisfaction, so the same family that founded Star’s still answers your call. Today, two generations of our family work together to carry that standard forward. We do not just clean surfaces; we build lasting partnerships rooted in reliability, responsiveness, and results.
Our crews receive ongoing training and supervision, and we follow detailed service scopes, with photo documentation available for applicable services and projects, so facility managers always know exactly what was done.
Star’s Janitorial Services is a locally owned and operated commercial cleaning company headquartered in Concord, California. Since 2012, we have served businesses and communities throughout the East Bay. We are independently owned and are not affiliated with similarly named cleaning companies in other states.
