A drain backed up into the downstairs bathroom during heavy rain. They contained it, took out what was ruined, disinfected everything, and cleared the smell. I did not have to touch a thing.
Harper D.Sewage came up through the floor drain and it was awful. The crew showed up in full gear, handled it safely, and dried it out. Respectful and professional through a rough day.

Call and dispatch

On-site assessment

Verify and bill
We log moisture readings until the structure is dry, then document the loss and bill your carrier directly.
Sewage and drain backups are the one water loss you should never clean up yourself. This is Category 3 black water, and it carries bacteria and other contaminants that make protective gear, containment, and proper disinfection non-negotiable. In Olympia, heavy rain can overwhelm the sewer system and push water back up through floor drains and lower-level fixtures, and an aging side sewer or a root-blocked line does the same. Precision Mitigation & Restoration is equipped to contain it, remove it, and disinfect the space so your home is safe again.
What makes sewage a biohazard
Black water is treated differently from clean water at every step. It requires care because it:
- Carries bacteria, viruses, and other pathogens that pose real health risks
- Soaks into porous materials that then cannot be safely saved
- Contaminates everything it contacts, spreading beyond the visible water
- Leaves odor and residue that require true disinfection, not just mopping
The CDC has clear guidance on the hazards of contaminated floodwater and sewage, which is why we handle it in protective gear and follow strict containment.
Sewage or a drain backup in your home? Do not touch it. Call our 24/7 Olympia line and a crew arrives in protective gear to handle it safely, 45 to 90 minutes out.
☎ Call (360) 498-7387How we clean up sewage safely
Every step is built around safety and full decontamination, not just removing the water.
- Contain the area so the contamination does not spread through the home
- Remove and dispose of porous materials that cannot be disinfected
- Extract the black water and clean and disinfect all affected surfaces
- Dry the structure to a verified reading and confirm the space is safe again
The EPA offers guidance on cleaning up after contaminated water. When it is a sewage loss, our crews take on the whole job and document it for your insurer.
Keep a backwater valve in mind if backups repeat
If your home backs up during heavy Olympia rains more than once, a backwater valve on the side sewer can keep the system from pushing sewage into your lower level. Ask a plumber about it after we clean up.

Sewage and Black Water Cleanup questions, answered
Water in your home right now?
Do not wait for the FAQ. An Olympia crew is standing by 24/7.
(360) 498-7387 Call nowWhy can I not clean up sewage myself?
Sewage is Category 3 black water carrying bacteria and pathogens, so it requires protective gear, containment, and disinfectants to handle without risking your health. It also soaks into materials that must be removed safely, which is not a household job.
Is sewage backup covered by insurance?
Sewer and drain backup is often a separate endorsement rather than part of a standard policy, so coverage varies. We document the loss thoroughly and bill your carrier directly if you carry that coverage.
What has to be thrown away after a sewage backup?
Porous materials that soaked up black water, like carpet, pad, and the lower part of drywall, usually cannot be safely disinfected and are removed. Hard, non-porous surfaces can be cleaned and disinfected in place.
Will the smell go away?
Yes. Proper removal, disinfection, and drying clear the odor at its source. Masking it without removing the contamination does not work, which is why we treat the cause, not the smell.
How fast can you respond to a sewage backup?
Most of Olympia and Thurston County is 45 to 90 minutes out, any hour. We treat black water as an emergency and roll a crew with the right protective equipment right away.
What causes sewage backups in Olympia?
Heavy rain overwhelming the sewer system, an aging or root-blocked side sewer, and a failed backwater valve are the common causes here. Backups often come during the same big storms that cause other flooding.
