About 83% of homes in San Miguel were built before 1980, and older clay or cast iron sewer pipes crack and clog with roots over time. Contra Costa County carries a Very High river flood risk rating from FEMA, and rising water can overload sewer pipes and push wastewater back up through floor drains.

A typical sewage & biohazard cleanup job includes:

  • Containment and negative air to keep contamination out of unaffected rooms
  • Raw sewage removal from floors, basements, crawl spaces, garages and utility rooms
  • Sanitizing after sewage reaches concrete slabs, tile grout and unfinished basement walls
  • Decontamination of HVAC components and air paths when sewage odor has spread
  • Commercial sewage cleanup in restaurants, offices, shops and apartment buildings

3. Cut out and discard

Contaminated drywall, trim and flooring are removed to clean material, and waste is sealed for proper disposal.

The crew treats lingering smells, checks air paths and walks the owner through what was done.

Common Questions About Sewage Cleanup in San Miguel

How long does sewage cleanup take?

Small jobs may be finished in a day, while larger ones with tear-out, drying and odor treatment take longer. The time depends on the area affected and what had to be removed. The crew can tell you what to expect after assessing the space.

What illnesses can raw sewage cause?

Sewage can carry germs such as E. coli, norovirus, hepatitis A and Giardia. They spread through skin contact, splashes and hand to mouth contact. Washing well and wearing protection reduce the risk, but removal by a crew reduces it most.

Do plumbers clean up sewage?

Plumbers usually clear the blockage or repair the pipe, but most do not remove contaminated materials or disinfect the space. A sewage cleanup company picks up where the plumber stops, and the two jobs often happen in sequence.

Do sewage cleanup companies handle commercial properties?

Yes. Commercial sewage cleanup in restaurants, offices, shops and apartment buildings follows the same biohazard steps, with added attention to keeping part of the building usable and to documentation for managers and insurers.

Who pays for sewage cleanup, the landlord or the tenant?

It depends on the cause, the lease and local law. A landlord's policy may cover the building, while a renter's policy may cover belongings. If the blockage was in a public sewer main, the city or utility may be responsible for the repair.

What if the sewage came from a septic tank?

A septic overflow is cleaned as raw sewage, both inside any affected building and on nearby ground. Contaminated soil, materials and surfaces are handled and disinfected. A septic service may also need to empty or repair the tank.

Raw sewage on the floor in San Miguel, CA?

Raw sewage is a biohazard, so do not wait on cleanup.
