About Us
Drain Cleaning Across California
We run California Drain Cleaning from our base at 3274 E Guasti Rd Ste 100 in Ontario, handling drain cleaning jobs for homes and businesses statewide. Our team works regularly in San Bernardino County and nearby cities such as Rancho Cucamonga, Upland, Fontana, and San Bernardino, where we see the same patterns of older piping, tree-root intrusion, and seasonal buildup that appear in many parts of the state.
We keep regular hours so customers know when to expect us: Monday through Friday 8am to 6pm and Saturday 9am to 2pm. Every job starts with a clear description of the work and an upfront quote, and we leave only after the customer has inspected the line and confirmed the flow is restored.
Because we cover the full state, our crews stay ready for the range of conditions found from coastal cities to inland valleys, adjusting methods for the hot-summer Mediterranean climate that drives increased grease and debris issues during long, warm periods.

- Fixed business hours posted so you can plan without guessing

What CA Customers Say
“My kitchen sink backed up with greasy water after cooking for a family dinner, and nothing I tried worked. California Drain Cleaning sent a tech who scoped the line and ran a powered auger through the main to break up the grease buildup. Water now drains right away without any gurgling.”
“The shower in my master bath was draining slow from hair and soap scum, leaving standing water after every use. They used hydro jetting on the branch line to clear it out completely. The flow is strong again and the floor stays dry.”
“Tree roots had invaded the main sewer line near my backyard, causing the toilet to bubble and the laundry sink to overflow. The crew located the blockage with a camera, cut the roots, and flushed the line. Everything works normally now with no recurring clogs.”
