How to Clean Up After a Toilet Overflows in Corvallis
Your toilet just overflowed and sewage is spreading across your Corvallis bathroom floor. This is not regular water damage. Toilet overflows are classified as Category 3 contaminated water, and the cleanup process requires disinfection, not just drying.
Harris Restoration
Why Toilet Overflows Are DangerousToilet water contains bacteria, viruses, and pathogens that cause illness
Even if the overflow looks clear, it's contaminated with fecal matter, urine, and other organic waste.
When this water contacts porous materials like grout, drywall, or carpet, those materials absorb the contamination and cannot be adequately disinfected
The water also spreads quickly into adjacent rooms, underneath baseboards, and through floor gaps into subfloor and ceiling spaces below.Immediate Steps After a Toilet OverflowStop the overflow by shutting off the water supply valve behind the toilet. It's a small valve near the floor that turns clockwise to close. If the valve is stuck or missing, shut off the main water supply to the house.
Do not touch contaminated water with bare hands. Put on gloves, remove any items from the wet area, and start soaking up water with disposable towels. Do not use your regular bath towels or cleaning rags.
Bag everything that contacted the water and dispose of it. Open windows and run fans to ventilate the space.Professional Sewage Cleanup and DisinfectionWe arrive in full PPE and establish containment to prevent cross-contamination. Then we extract contaminated water using truck-mounted vacuums, remove porous materials that contacted sewage, and bag them for disposal.
Hard surfaces like tile and concrete get scrubbed with EPA-registered disinfectants rated for sewage contamination. We treat walls and framing with antimicrobial solutions and dry everything to below 15 percent moisture content. Air scrubbers with HEPA filters run continuously to capture airborne particles.
Only after surfaces pass disinfection testing do we begin restoration.Insurance Coverage for Toilet OverflowsToilet overflows caused by a blockage in your plumbing are usually covered.
