Sewage Removal and Disinfection in Gilroy, CA

Sewage restoration is the work of returning a space to safe, usable condition after a backup. It starts with removing contamination, and repairs and rebuilding only follow once the area is clean.

Need residential or commercial sewage cleanup in Gilroy or nearby parts of Santa Clara County? Call Gilroy Biohazard Cleanup Help for help in your basement, crawl space, garage, restroom, kitchen or utility room, wherever wastewater has spread.

Only about 36% of homes in Gilroy were built before 1980, but newer pipes can still fail from roots, blockages or ground movement. Gilroy averages about 20 inches of rain a year. Backups here usually come from blockages, roots or broken pipes rather than storms, but the cleanup is the same.

The work often covers:

  • Cleaning and sanitizing of salvageable furniture, appliances and stored belongings
  • Decontamination of HVAC components and air paths when sewage odor has spread
  • Cleanup after toilet, tub, shower and floor drain overflows
  • Cleanup of sewage under a house or in a crawl space where pipes have failed
  • Sanitizing after sewage reaches concrete slabs, tile grout and unfinished basement walls

Step by Step: Sewage Removal and Disinfection in Gilroy, CA

1. Safety check and containment

The crew checks for electrical and slip hazards, puts on protective equipment and seals off the affected area so sewage does not spread.

2. Remove the liquid

The team takes out all standing wastewater and wipes down wet surfaces before touching anything else.

3. Removal of porous materials

Carpet, padding, drywall and insulation that soaked up sewage are cut out, bagged and hauled away as contaminated waste.

4. Sanitizing and deodorizing

Remaining surfaces are washed and disinfected, and odor is removed at its source rather than covered up.

Sewer Backup Questions Answered for Gilroy, CA

Can sewage backup make me sick even after it is cleaned up?

If the cleanup missed contaminated materials, germs and odor can linger. That is why crews remove porous materials, disinfect every surface they touched and inspect the work. Thorough removal is what lowers the risk.

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.

What are the signs of a sewage leak?

Watch for a rotten-egg or sewer smell, wet spots or stains on floors and walls, unusually green grass over a pipe, and multiple drains backing up at the same time. If any of these show up, keep people away from the area and have the cause checked.

Can carpet be saved after a sewage backup?

Usually not. Carpet and padding soak up Category 3 water and cannot be reliably made safe, so they are cut out and discarded. Hard surfaces, sealed wood and items in closed containers can often be cleaned and kept.

What should I do right after a sewage backup?

Keep everyone out of the area, including pets, and stop using sinks, tubs and toilets that feed the pipe. Turn off power to wet areas only if it is safe. Then call a cleanup team and your insurer, and take photos before anything is moved.

How do I clean sewage off concrete?

Concrete is porous, so sewage soaks in. The surface is scrubbed, rinsed and treated with a disinfectant, and the wash water is collected rather than spread. Stubborn odor may need a second round of treatment.
