38 Years Keeping Inland Empire Buildings Spotless

DBM started in 1987 as Davenport Building Maintenance with a single construction clean-up account in Lake Elsinore. Three generations of the Davenport family later, we run nightly and weekly janitorial programs for offices, medical suites, warehouses, restaurants, schools, and wineries across Riverside County and North San Diego County. We are commercial only, and we build our reputation one dependable shift at a time.

Straight Answers

How Much Does Commercial Cleaning Cost in Riverside County?

Most commercial cleaning in the Temecula and Murrieta area runs about $0.05 to $0.30 per square foot per visit, or roughly $250 to $600 to clean a 5,000 sq ft office one time. Recurring janitorial contracts usually land between $200 and $3,000+ per month depending on square footage, how often you need service, and the scope of work.

Medical, food-service, and industrial facilities typically run higher because of specialized disinfection and compliance requirements. The honest answer is that every building is different, which is why we start with a free walkthrough and give you a clear, itemized quote with no surprises.
