Referral service, not a contractor. SF Drain & Sewer Pros does not perform plumbing, drain, or sewer work. Calls to (415) 555-0100 are connected to an independent, licensed local provider, who may pay us for the referral. Always confirm the provider's license and get a written estimate. How this works
Clogged drain or sewer backup in San Francisco?
San Francisco's housing stock is old. Many homes and flats were built before 1940, and the city's hilly lots and mature street trees are hard on underground pipes. Slow drains, gurgling toilets, and backups are common, and they're easier and cheaper to fix early.
Sewage coming up a drain right now? Stop using all water fixtures (no flushing, showers, dishwasher, or laundry), keep people and pets away from the wastewater, and call a drain professional. Read the step-by-step backup guide.
