For sewer problems, call us first, at 707-258-6000, ext. 9. Day, night, weekends, or whenever, if you’ve got a problem with your drains, just call us first. If the problem is in our sewage mains or laterals, we can save you the cost of a plumber's visit. Our answering service will take your name, address, and telephone number, and a member of our crew will call you back or be on your doorstep within 30 minutes.
Our services are free of charge. Keep in mind that the sewer lateral from the property line to the house is the responsibility of the property owner. If the problem turns out to be in your section of the sewer line, you may still need a plumber’s help.
