Robinson Restoration handles category 3 sewage cleanup in Seattle, WA with biohazard-certified crews, 24 hours a day. We contain the area, extract the sewage, remove contaminated porous material, disinfect with EPA-registered products, dry the structure to IICRC S500 targets, and document every step for your insurance carrier.
It has rained for four days, and now there is water on the basement floor that did not come from any pipe you can see. It came up the floor drain, and it smells like what it is. Sewage cleanup in Seattle starts with that call.
The house is the reason. Most of the older neighborhoods went up between 1900 and 1930 over full basements, and the side sewer running from that basement to the street is often the original clay pipe. Clay joints open, tree roots find them, and the line narrows a little more every year until a wet week finishes the job. Large stretches of the older city also carry rain and sewage in one pipe, so a long storm fills the main while your lateral is already choked. The lowest opening in the house takes the pressure: the basement floor drain, the laundry standpipe, the toilet in a basement bathroom. If that basement holds a bedroom or a rental unit, it is a finished room, not a utility corner.
Robinson Restoration dispatches Seattle sewage calls from the operations center in Kent. A person answers at any hour, and the crew is on-site in 90 minutes or less. Speed matters more on sewage than on clean water. Bacteria multiply fast in warm, wet carpet pad and drywall, and the first 24 hours decide how much of the basement gets cleaned versus torn out. The crew seals the basement, shuts the HVAC off, extracts with dedicated equipment, bags out what soaked, disinfects the hard surfaces with EPA-registered antimicrobials and dries the structure to IICRC S500 targets with readings logged daily. You get photos of every stage, a written scope, and direct billing to your carrier.
On a Seattle basement backup the order never changes: seal the room first, take out what soaked, then prove with a meter that the framing is dry.
The affected area is sealed, the HVAC is shut off and the crew is in full PPE before anything is touched. Sewage and solids come out with dedicated extraction equipment, not the shop vac in your garage.
Carpet pad, drywall, insulation and anything porous that touched the water gets bagged out under containment. Hard surfaces are cleaned and disinfected with EPA-registered antimicrobials.
Structural drying runs to IICRC S500 targets with moisture readings logged daily, and the file goes to your adjuster with photos of every stage. Any rebuild is managed through vetted licensed contractors and sister companies.
A cracked clay lateral is the usual start of a Seattle basement backup, and it fails on the wettest week of the year. Roots grow into the open joints, paper and grease catch on the roots, and the pipe closes down until the basement drain is the only way out. Getting the line open is a plumber's job. Everything after that is sewage cleanup, and it is ours: containment, extraction, removal, verified drying.
In the older parts of the city one pipe carries both stormwater and sewage, so a storm that runs for days can push the main past capacity even if your own lateral is clear. The flow reverses at the lowest opening in your house. What comes up is category 3 water no matter where it started, and it is handled the same way: full PPE, containment, and the porous materials removed rather than dried.
A lot of Seattle basements have become bedrooms, offices and rental units, so the backup lands on carpet and drywall instead of a bare slab. That changes the scope. Carpet pad, the bottom of the drywall and the insulation behind it come out under containment, and contents get sorted into what can be disinfected and what has to go. For a rental, the file shows dates, photos and scope for tenant and carrier alike.
Seattle sits on glacial till and dense clay, so winter rain does not soak down. It moves sideways along the hill until it finds a foundation, and a basement that was already damp at the perimeter dries slower once the sewage is out. Drying it back to IICRC S500 targets takes longer than a dry slab would, and we log the readings daily until the numbers hold, not until a set number of days has passed.
Most of the sewage calls we run in Seattle start in one of three places: main lines blocked by tree roots, basements, and municipal surcharges during heavy rain. Where the backup starts decides how far it spreads, what has to be removed, and which parts of your policy apply.
The side sewer from a 1920s house to the street was laid in short clay sections, and every joint is a door for roots. Once the line is mostly blocked, a heavy load of rain or a full load of laundry is enough to send the flow back up the basement drain instead of out to the main.
Seattle basements are the lowest point on the lot and the lowest point in the plumbing, so they take the backup first and hold it longest. The floor drain, the laundry standpipe and an old basement toilet are the openings. Concrete can be cleaned and disinfected. The carpet pad and the bottom of the drywall cannot.
Where stormwater and sewage share a pipe, a long rainy stretch can fill the main faster than it drains. The system relieves itself into the lowest connected fixture, and on a hillside street that is usually a basement below the road. Clearing your own line does not help when the pressure is coming from the main.
Water is how most losses start. It’s rarely where they end. The same local crew handles all of it.
When a backup takes out flooring, drywall or a finished basement, we manage the rebuild too. Drag the handle to compare a documented Robinson project.
“Had a leak in our wall and our plumber recommended Robinson Restoration to handle remediation of the water damage. Christian and Adolfo were awesome. Great communication throughout the setup of the containment area and installation of the equipment to start the drying process.”

“Just started a project with Cole and Chuck at Robinson Restoration and had to write a review straight away. These guys have been fantastic. We were away on a week long trip when we had a kitchen leak that destroyed our flooring and subfloor.”

Sewer backup coverage is policy-specific, and many Washington policies only cover it through a sewer and drain backup rider. We review your policy language before you file, document the Seattle loss with photos, moisture readings and a written scope, and bill your carrier directly for covered work. You pay your deductible.
Subject to policy coverage and deductible. We handle the paperwork, photos, and adjuster calls.
When you search for sewage cleanup near me in Seattle, the name that matters is the one whose crew is already in a truck. Robinson Restoration dispatches from Kent, a person answers at any hour, and the crew arrives with containment, PPE and dedicated extraction equipment. The inspection is free. What you get is a sealed basement, removed materials photographed before they leave, and a file your adjuster can approve.
Usually the cleanup is yours to start, whatever the cause. The side sewer from the house to the main is generally the owner's pipe to maintain, and a root-blocked clay lateral is a private-side failure. If the city main surcharged in the storm, that is a separate conversation with the utility, and it does not stop bacteria multiplying in your carpet pad while you wait. Robinson Restoration starts containment and extraction on the first visit and documents the source for whichever claim applies.
That depends on your policy language and on how the loss started. Sewer backup is policy-specific, and many Washington policies only pay for it through a sewer and drain backup rider. Robinson Restoration reviews your policy with you before you file, photographs the basement before anything is moved, writes a scope of what comes out and bills the carrier directly for covered work. If the rider is not there, we tell you up front instead of after the demo.
Often yes, once the basement is sealed. The crew closes off the work area, shuts the HVAC down so contaminated air does not travel through the ducts, and runs the extraction and removal under containment. Whether you stay depends on where the furnace and the water heater sit, whether the basement holds the only laundry, and how much of the floor above is affected. We tell you on the first visit. Kids and pets stay away from the basement until the drying is verified.
Anything porous that soaked goes: carpet pad, the wet band of drywall, insulation behind it, cardboard boxes, upholstered furniture that sat in the water. Hard surfaces stay and get cleaned, disinfected with EPA-registered antimicrobials and verified: the concrete slab, metal shelving, tile, sealed wood that only got splashed. The line between the two is contact with category 3 water, not how the item looks after it dries. Bagging the porous material out under containment is what keeps the rest of the house clean.
Fast. Sewage carries E. coli, salmonella, hepatitis A and parasites you cannot see or smell, and bacteria multiply quickly in warm, wet material. The first 24 hours are the danger window: what is extracted and bagged inside that window is a cleanup, and what sits past it becomes a tear-out. Do not wade in, even in boots, and do not run fans or a shop vac, because both spread contamination. Photograph the room from the stairs, stop using water in the house, and call.
Robinson Restoration manages the rebuild through vetted licensed contractors and sister companies. The person who scoped the tear-out is the same one managing the drywall, flooring and trim going back in. Rebuild starts once the drying readings hold at IICRC S500 targets, not before, and the rebuild scope is written separately from the cleanup and goes to your adjuster with the photos from every stage.
