Sewage backup cleanup in Tiburon, CA

Sewage is grossly contaminated (Category 3) water. A backup calls for professional cleanup and a plumber to fix the cause. Here's what that looks like in Tiburon, what to do, and how to get connected with an independent, licensed local provider.

Sewage backup cleanup in Tiburon: what we see

Tiburon's homes from the 1950s–70s are old enough for laterals to need attention, and hillside lots mean long runs downhill. Large landscaping and trees near laterals add root pressure.

The local picture

House age and sewer laterals. The age of the house is a good guide to the age of the lateral. Tiburon has mid-century and contemporary hillside homes with view decks and large windows, homes on the flats near Blackie's Pasture, and older homes near Old Tiburon.

Lot, slope and trees. Long laterals, steep runs and big trees all raise the odds of trouble. Tiburon spans a peninsula with steep, exposed slopes facing the bay and wind, plus flatter shoreline areas.

Conditions vary a lot from street to street in Tiburon, so a provider should assess your specific home.

What to do right now

  1. Keep everyone, especially children and pets, out of affected areas.
  2. Stop using water: no flushing, showers, dishwasher or laundry.
  3. Don't touch sewage without boots, gloves and eye protection.
  4. Photograph the damage for insurance.
  5. Call a plumber for the cause and a restoration provider for cleanup.

  • Find your sewer cleanout so a plumber can reach the lateral quickly.
  • Have the lateral camera-inspected if you have big trees and an older home.
  • Keep grease and wipes out of drains.
  • Check whether your policy has a sewer or water backup endorsement.
