Robinson Restoration handles category 3 sewage cleanup in Olympia, 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.
Third day of rain and the basement floor drain is bubbling. Then it is rising, and it smells like the sewer because it is the sewer. In an older Olympia house near high groundwater, that drain is the lowest opening, and the sewage cleanup starts there.
Olympia gets more rain than Seattle, and the wet season runs from October into spring without a real break. By January the ground under the older neighborhoods around the Capitol campus is saturated, groundwater is at its winter high, and the sewer mains are carrying that load too. Houses in the oldest parts of the system still drain through clay side sewers, and roots have had a century to find the joints. When a heavy rain surcharges those lines, the sewage comes back through your lowest opening, and in a South Capitol basement that is the floor drain. On the west side it is a slab-level bathroom in a 1970s home where groundwater is already pushing up through the slab.
Robinson Restoration dispatches Olympia from the Kent operations center, which handles Thurston County alongside King and Pierce. A person answers 24/7 and the crew is on-site in 90 minutes or less. The basement is contained with the HVAC off, the sewage extracted, the porous material bagged out. Hard surfaces get EPA-registered antimicrobials, then the structure dries to IICRC S500 targets with readings logged daily. We photograph every stage and document the cause, because a municipal surcharge and a blocked side sewer are two different conversations with your carrier. Billing goes direct to the carrier, and any rebuild runs through vetted licensed contractors and sister companies.
In an Olympia basement with groundwater already in the slab, the Verify step is the one we refuse to rush.
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.
In the older South Capitol homes with a basement, the floor drain sits below every other fixture, so when the sewer main surcharges, that is where it surfaces. It needs no blockage in your line. It comes up because the city system is full and your drain is the nearest low point. Everything stored on that floor, carpet, cardboard, the bottom of the paneling, touched category 3 water, and it comes out.
Thurston County groundwater peaks in the same weeks the mains carry the most rain, and an Olympia basement can take both at once. That changes the sewage cleanup. It gets contained, extracted and removed, but drying to IICRC S500 targets on a slab that groundwater keeps damp is slower and must be measured daily, and the file has to separate what the backup did from what the groundwater did. Your carrier will.
The oldest parts of the sewer system serve Olympia's oldest houses, and the private lines running out to the main are clay with roots in the joints. Under a long rain, a root-choked line stops passing water and the backup finds your lowest drain. Same category 3 water, but the cause is on your side of the property line, which changes both the repair and the claim. The crew notes what came up before anything moves.
The Craftsman bungalows near the Capitol campus sit on post-and-pier foundations over shallow crawlspaces, with original cast iron waste lines under the floor. When one cracks, the sewage goes into the crawl instead of up a drain and soaks the soil and the insulation under the floor. That is a sewage job in a tight space: containment at the hatch, removal of what soaked, and a dry-out that is verified, not assumed.
Most of the sewage calls we run in Olympia start in one of three places: floor drains and the lowest fixtures, municipal surcharges during heavy rain, and main lines blocked by tree roots. Where the backup starts decides how far it spreads, what has to be removed, and which parts of your policy apply.
In an older Olympia home the basement floor drain is the lowest opening on the whole line, which is why a winter surcharge arrives there and nowhere else. The first sign is bubbling or a wet ring around the drain during a long rain, and by the time the water is across the floor it has reached everything stored on it.
When a multi-day rain loads the mains and the groundwater is already at its winter high, the city system can surcharge back through private connections. Your line may be clear. The sewage still comes up your lowest drain, and it is still category 3 water that needs containment and removal, not a mop.
Clay side sewers under the oldest neighborhoods take roots at every joint. A blocked line stops every drain in the house, and the backup surfaces in the basement or the ground-floor bathroom. Roots on your side of the line are a different claim than a city surcharge, so the cause gets documented first.
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 Olympia 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.
Sewage cleanup near me in Olympia, during a rain that will not stop, means a crew from Robinson Restoration's Kent operations center in full PPE with dedicated extraction equipment, on-site in 90 minutes or less. They contain the basement, get the sewage out, remove what soaked and dry the slab to a measured target. The inspection is free, and a person answers the phone at any hour.
Upstairs, usually yes, with the HVAC off and nobody going downstairs. Sewage is category 3 black water carrying E. coli, salmonella, hepatitis A and parasites you cannot see or smell, so the basement is off limits: no wading in, even in boots, no fans, no touching outlets near the water. Keep kids and pets upstairs and stop using water. If the furnace or the only bathroom is in the wet zone, say so on the call and we will tell you straight. Robinson Restoration answers 24/7 and is on-site in 90 minutes or less.
Because the loss is inside your house, and that is what your policy covers or excludes. A municipal surcharge during heavy rain is one of the common causes we document, and the documentation matters: sewer backup coverage is policy-specific, and many Washington policies only pay through a sewer and drain backup rider. Robinson Restoration photographs the drain and the waterline, notes the cause, reviews your policy language with you before you file and bills the carrier directly for covered work.
No. A shop vac spreads category 3 water, a mop pushes it into the concrete and under whatever it is sitting on, and bleach on a wet carpet pad does nothing to the pad. Porous material that touched it has to be removed under containment, and the hard surfaces need EPA-registered antimicrobials and verification, not a household spray. What you can do before the crew arrives is stop running water, keep everyone out, turn off the HVAC and take photos from the top of the stairs.
Porous material that touched the sewage comes out: carpet and pad, the bottom of drywall or paneling, insulation, cardboard and anything upholstered that sat on the floor. Hard surfaces stay: the slab, the drain, tile and metal shelving get cleaned, disinfected with EPA-registered antimicrobials and verified. Groundwater complicates the drying, not the removal. The slab in an Olympia basement in January dries to IICRC S500 targets on its own schedule, and the readings are logged daily until it gets there.
Which fixtures backed up, and whether the rest of the house still drains, are the first clues, and the crew writes down both before anything is moved. Roots in a clay side sewer, a failed pump and a city surcharge are three different claims, and the file has to say which one this was. Robinson Restoration photographs the drain and the fixtures and writes the cause into the scope. A plumber's camera inspection settles it, and that report goes in the same file.
Removal and disinfection are the fast part. Drying is what takes days, and in an Olympia basement during the wet season the slab is fighting groundwater the whole time, so the crew dries to IICRC S500 targets and logs the readings daily instead of guessing from how the floor feels. When the readings hit target and the surfaces are verified, the containment comes down. If drywall or flooring came out, the rebuild is managed through vetted licensed contractors and sister companies with the same project manager.
