Sewage Backups Are a Category 3 Biohazard — Not a DIY Job
Black water contains bacteria, viruses, and parasites that cause serious illness.
Per the IICRC S500 standard, sewage is classified as Category 3 'black water' — the most contaminated and dangerous water loss possible. It contains E. coli, Hepatitis A, Salmonella, Giardia, Rotavirus, and other pathogens capable of causing severe illness, especially in children, the elderly, and immunocompromised individuals.
Anything porous touched by sewage — carpet, pad, drywall, insulation, particleboard, upholstered furniture, and most flooring underlayment — must be removed and discarded. There is no safe way to clean and reuse these materials. Hard, non-porous surfaces require professional disinfection with hospital-grade EPA-registered antimicrobials, applied at the correct dwell times.
Portland sees sewage backups most often during heavy rain when combined sewer systems overflow, after main-line clogs from tree roots, and from failed sump pumps in older basements. Whatever the cause, the response is the same: contain the contamination, remove all affected porous materials, sanitize every hard surface, neutralize the odor at a molecular level, and dry the structure to verified standards. We are equipped, certified, and willing to do every step safely.
Health & Property Risks of Untreated Sewage
The longer you wait, the worse — and more expensive — it gets.
Disease Exposure
E. coli, Hepatitis A, and other pathogens cause serious gastrointestinal and respiratory illness.
Airborne Contamination
Sewage gases and aerosolized bacteria spread through HVAC systems within hours.
Pest Attraction
Untreated waste attracts rodents, flies, and cockroaches — adding a second infestation problem.
Structural Saturation
Black water destroys drywall, insulation, subfloors, and framing within 24-48 hours.
Permanent Odor
Sewage odor bonds to porous materials and HVAC ducts — only molecular treatment removes it.
Insurance Complications
Improper DIY cleanup can void coverage and invalidate your homeowner's claim.

Frequently Asked Questions
Answers to what Portland homeowners ask us most.
Is sewage backup really dangerous?+
Yes. Sewage contains live pathogens like E. coli, Hepatitis A, Salmonella, and Giardia that cause serious illness through skin contact, ingestion, or inhalation of aerosolized droplets. Children, pets, and immunocompromised individuals are especially at risk.
Can I clean up sewage myself?+
We strongly advise against it. Without proper PPE, containment, and EPA-registered disinfectants, you risk illness, spreading contamination through your HVAC system, and voiding your insurance coverage. Sewage is a Category 3 biohazard.
Will insurance cover sewage backup?+
Standard homeowner's policies often exclude sewer backup, but many carriers offer affordable sewer-backup riders. Check your declarations page or call your agent. We help document the loss either way for your claim.
What needs to be thrown away after sewage exposure?+
Per IICRC S500: carpet, pad, drywall (typically 2 feet above the water line), insulation, particleboard, upholstered furniture, and any porous material that contacted contaminated water must be removed and disposed of as biohazard waste.
How long does sewage cleanup take?+
Most residential sewage cleanups take 3-7 days: emergency containment and removal in day 1, sanitization in days 2-3, and verified structural drying over the following 3-5 days.
Will the smell really go away?+
Yes — when treated correctly. Surface deodorizers only mask odor. We use hydroxyl generators or ozone treatment that breaks down odor molecules at the source for permanent removal.
Do you handle commercial sewage backups?+
Yes. We respond to restaurants, offices, multi-family buildings, schools, and retail spaces with discretion and after-hours availability to minimize business interruption.
