  • Odor removal and deodorizing after the sewage has been taken out
  • Disinfection of hard surfaces, framing and subfloors with EPA-registered products
  • Cleanup after toilet, tub, shower and floor drain overflows
  • Tear-out of sewage-soaked carpet, padding, drywall, baseboards and insulation

The Sewage Backup Cleanup Process in Ontario

1. Walk through the damage

Technicians trace the sewage from the source to the farthest wet spot, including under cabinets and into wall bases.

2. Sewage extraction

Standing sewage is pumped or scooped out, and the contaminated area is mapped to see how far the liquid traveled.

3. Cut out and discard

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

4. Sanitizing and deodorizing

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

Sewage Cleanup Frequently Asked Questions in Ontario, CA

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 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.

How do I clean up a sewer backup?

Keep people and pets out, turn off power if water is near outlets, and avoid touching the sewage. Safe cleanup needs protective gear, extraction, removal of soaked materials and disinfection. For anything more than a small spill, a cleanup company is the safer choice.

What is Category 3 water, also called black water?

Category 3 water is the most contaminated level, and sewage is the standard example. It can carry disease-causing germs and should never be cleaned with household supplies alone. Flood water that touched sewage is treated the same way.

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.
