Renters make up about 48% of households in Portland. Tenants should tell the landlord right away, and the cleanup team can provide documentation for the lease and any claim. Multnomah County carries a Relatively High river flood risk rating from FEMA, and rising water can overload sewer pipes and push wastewater back up through floor drains.
What sewage & biohazard cleanup covers:
Doors are closed, vents covered and the work area is isolated so contamination stays where it started.
Standing sewage is pumped or scooped out, and the contaminated area is mapped to see how far the liquid traveled.
Carpet, padding, drywall and insulation that soaked up sewage are cut out, bagged and hauled away as contaminated waste.
Disinfectant is applied to every affected surface, the space is dried and aired out, and the crew inspects the finished work.
Most sewage & biohazard cleanup jobs in Concordia, Portland, OR cost between $1,500 and $10,000, based on published cost guides.
Commercial sites can cost more or less depending on access, hours and how much of the building has to stay in use during cleanup.
| Type of job | Typical range |
|---|---|
| Most homeowners | $2,000 - $10,000 |
| Category 3 sewage | $7.50 - $7.50 per square foot |
| Published span | $1,500 - $8,000 |
| Category 3 sewage | $2,500 - $10,000 |
These ranges come from published cost guides (Bob Vila, Fixr, BioCleaners Directory, Biohazard cleanup company pricing guide) and are not a quote for Concordia. Price drivers include square footage affected, category of water, porous materials that must be removed, drying time. For a real number, call (877) 812-4220.
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.
After the sewage and soaked materials are out, floors and walls are scrubbed with a cleaner, then treated with an EPA-registered disinfectant used by label directions. Unsealed concrete can hold odor and needs extra attention. Crews often handle this step with professional equipment.
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.
The price depends on how much sewage there is, how far it spread and which materials must be removed. A bathroom overflow costs less than a flooded basement. The team sets the price after seeing the space, and nothing is decided on a call alone.
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.
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.
