Why Bothell Homeowners Call Us First
A sewage smell is a sign that waste is still sitting somewhere in your home. We remove it, disinfect the space, and verify the air is clean before we pack up.
Odor Gone, Not Masked
We do not fog the room and leave. We pull the contaminated carpet, cut out sewage-soaked drywall, and treat the framing with an antimicrobial solution. In most Bothell homes the smell is noticeably gone within 24 hours, and fully gone once the structure reads dry on our moisture meter.
Fast Response, Day or Night
Sewage smell gets worse with every hour it sits. We run 24/7 sewage smell removal in bothell, so a call at 2 a.m. gets a real person and a crew headed your way. Most Bothell addresses see us on site within 60 to 90 minutes.
Certified, Insured Technicians
Our techs hold IICRC WRT and IICRC ASD certifications and follow OSHA 10 safety rules on every sewage job. That matters when waste water is involved. We wear full PPE, set containment barriers, and keep the rest of your home out of the contamination zone.
We Work With Your Insurance
Sewage backup claims are common, and we document them the way adjusters expect. We photograph the damage, log moisture readings, and build the scope in Xactimate so your claim moves faster. That is a big part of why homeowners call us for affordable sewage odor removal bothell Washington.
Our Sewage Odor Removal Process
Every job follows the same five steps. You will know what is happening, how long it takes, and when the air in your home is safe again.
Inspect and Locate
We walk the space with a moisture meter and thermal imaging camera to find every wet or contaminated spot, including behind walls and under flooring. This usually takes 20 to 30 minutes. You get a clear picture of the source before we touch anything.
Contain and Remove
We set containment barriers and put on PPE, then pull sewage-soaked carpet, absorbent pads, and any contaminated drywall. A portable sewage pump and wet/dry vacuum handle standing waste water. This is the step that removes the source of the odor.
Extract and Disinfect
A truck-mounted water extractor pulls the remaining water from the subfloor, then we apply an EPA-registered disinfectant and biocide to every affected surface. Framing, baseboards, and concrete get treated. This is where the sewage smell removal bothell work really happens.
Dry and Purify
We place Dri-Eaz and Phoenix Restoration Equipment air movers and dehumidifiers, plus air scrubbers with HEPA filters. Drying typically runs two to four days. We check readings daily and do not pull equipment until the structure is dry.
Verify and Restore
We confirm the odor is gone and the moisture readings are back to normal, then replace what we removed. That can mean new drywall, flooring, or sewage-resistant insulation. You get a walkthrough and a written summary of everything we did.
Local Experience You Can Check
Sewage odor is a restoration problem, not a cleaning problem, and we treat it that way. Our technicians are trained through the IICRC in water damage restoration (WRT) and applied structural drying (ASD), and we follow Washington State Department of Health regulations for handling sewage-contaminated material. We work with RIDGID and Shop-Vac extraction gear, Dri-Eaz and Phoenix Restoration Equipment drying equipment, and Jon-Don supplies on every job. We know Bothell building stock, from older homes near Bothell Landing to newer construction in North Creek, and we know how our wet winters push crawl space contamination and basement flooding calls.

What Our Sewage Odor Removal Includes
Every job starts with a full inspection and ends with a verified dry structure and clean air. We remove the source, disinfect the space, and dry it out. If rebuilding is needed, we handle that too. Here is what is covered on a standard sewage odor removal call in Bothell.
What's Included
Source Inspection and Mapping
We use a moisture meter and thermal imaging camera to find every wet and contaminated spot, including behind walls and under flooring. You get a clear explanation of where the odor is coming from and what it will take to remove it.
Contaminated Material Removal
Sewage-soaked carpet, pad, contaminated drywall, and sewage-resistant insulation that has been exposed get removed and bagged for proper disposal. This is the step that eliminates most of the odor at the source.
Extraction and Disinfection
A truck-mounted water extractor and portable sewage pump remove standing waste water. We then apply an EPA-registered disinfectant and biocide to the subfloor, framing, and concrete to kill the bacteria causing the smell.
Commercial Drying
Dri-Eaz and Phoenix Restoration Equipment air movers and dehumidifiers run until the structure reads dry on our meter, usually two to four days. Air scrubbers with HEPA filtration run alongside to clear airborne particles and odor.
Odor Verification
Before we pull equipment, we confirm the odor is gone and moisture readings are back to normal. If any smell remains, we keep treating. You get a final walkthrough so you can check the space yourself.
Sewage Smell Problems We Solve in Bothell
A sewage smell is a symptom, not the problem. These are the issues we find behind most odor calls in Bothell, and how we fix each one.
Sewage smell coming from the basement after a backup
The odor drifts upstairs and into living areas, and the moisture left behind feeds mold growth after sewage within 24 to 48 hours.
We extract the standing water, pull any sewage-soaked carpet, and disinfect the concrete and framing. Dehumidifiers dry the space, and we verify with a moisture meter before we finish. Most basements smell clean within two days.
Persistent odor from a crawl space
Crawl space contamination keeps the whole house smelling, and Bothell's damp winters make it worse because the space never dries on its own.
We remove contaminated insulation, treat the soil and framing with an antimicrobial solution, and run dehumidifiers until the space is dry. We also check for the slow leaks that let sewage in to begin with.
Smell that returns after a DIY cleanup
Household cleaners kill surface bacteria but leave sewage in the carpet pad, subfloor, or wall cavity, so the odor comes back within days.
We find what was missed using a thermal imaging camera, remove the contaminated material, and disinfect the surfaces underneath. That is what makes the fix permanent instead of temporary.
Odor after a toilet overflow that sat overnight
Waste water soaks into the subfloor and the smell spreads through the room and into adjacent spaces, and the longer it sits the more material has to be replaced.
We pull the saturated carpet and pad, extract the water, and treat the subfloor with EPA-registered disinfectant. Drying equipment finishes the job. Most overnight overflows are handled in a single visit plus two to three days of drying.
When Bothell Homes Need Sewage Odor Removal
A finished basement floods with sewage after heavy fall rain in Bothell.
We pump and extract the waste water, remove sewage-soaked carpet and contaminated drywall to the flood line, disinfect the framing and concrete, and run commercial dehumidifiers until the space reads dry.
The basement smells clean within 48 hours, and the structure is dry enough to rebuild without risking mold growth after sewage.
A rental property in Canyon Park has a toilet overflow that goes unnoticed for two days.
We extract the water, pull the saturated carpet and pad, treat the subfloor, and document everything in Xactimate for the landlord's insurance claim. Air scrubbers run during the drying phase.
The odor is gone, the unit is rentable again in under a week, and the landlord has the paperwork to support the claim.
A homeowner near Silver Lake notices a sewer smell in the hallway but no visible water.
We trace the odor with a moisture meter and thermal imaging camera, find contaminated drywall behind the baseboard, cut it out, treat the framing, and dry the wall cavity.
The hidden source is removed, the hallway smells normal again, and the repair is limited to one section of drywall instead of the whole wall.
A crawl space in Westhill stays damp all winter and starts smelling like sewage.
We remove contaminated insulation, treat the soil and joists with an antimicrobial solution, and run dehumidifiers until the space is dry. We also look for the drain line leak feeding the problem.
The crawl space dries out, the smell stops drifting into the living space, and the homeowner avoids a larger mold remediation down the road.
Tools and Methods We Use
Tools & Equipment
Truck-Mounted Water Extractor
Pulls large volumes of waste water out of carpet, pad, and subfloor fast. It removes the water that would otherwise keep feeding the odor and the bacteria behind it.
Portable Sewage Pump
Handles standing sewage in basements and crawl spaces where a truck mount cannot reach. We use it to clear the space before extraction and disinfection begin.
Dri-Eaz and Phoenix Restoration Equipment Dehumidifiers
Remove moisture from the air and structure during the drying phase. Drying usually runs two to four days, and we check readings daily until the space is dry.
Air Scrubber with HEPA Filtration
Filters airborne particles and odor during drying. It runs alongside the dehumidifiers so the air in your home clears while the structure dries.
Moisture Meter and Thermal Imaging Camera
Find wet material behind walls and under floors that you cannot see. This is how we locate the source of a smell when there is no visible water.
RIDGID and Shop-Vac Wet/Dry Vacuums
Pick up residual waste and water in tight spaces after the main extraction is done. They let us clean corners, baseboards, and crawl space edges thoroughly.
Methods
IICRC WRT and ASD Standards
Our technicians follow IICRC Water Damage Restoration and Applied Structural Drying standards on every job. That means documented moisture readings, verified drying goals, and a structure that is actually dry before we call the job complete.
EPA-Registered Disinfection
We apply EPA-registered disinfectant and biocide to every surface sewage touched. This kills the bacteria that cause odor and reduces the health risk from handling waste water in your home.
Containment and PPE Protocol
We set containment barriers to keep the contamination zone separate from the rest of your home, and our crews wear gloves, respirators, and Tyvek suits. OSHA 10 safety rules govern how we work around sewage.
Xactimate Documentation
We build the scope in Xactimate, photograph the damage, and log daily moisture readings. This gives your insurance adjuster the documentation they need and keeps your claim moving instead of stalling.
How Sewage Odor Removal Works in Bothell
Bothell's wet fall and winter push a lot of sewage odor calls our way. Older homes near Downtown Bothell and Bothell Landing often have cast iron or clay drain lines that crack and back up, while newer construction in North Creek and Canyon Park tends to have finished basements where a backup soaks carpet and drywall fast. Crawl spaces are common in the older neighborhoods, and once sewage gets into a crawl space, the damp air keeps the smell alive until the space is dried properly. We follow Washington State Department of Health regulations for handling sewage-contaminated material, and we work with King County homeowners on insurance claims every week. If you need emergency sewage smell removal service bothell WA, we know which streets flood first and how to get equipment to your door quickly. We serve ZIP codes 98021, 98011, and 98041.
Service Areas
Older homes close to the river with original drain lines. Backups here often involve cast iron pipes and crawl spaces that stay damp through winter.
A mix of newer homes and commercial buildings. Finished basements are common, so a backup usually means carpet and drywall removal plus several days of drying.
Many rentals and multi-family properties. We handle a lot of insurance-documented sewage odor jobs here for landlords who need fast turnaround between tenants.
Sloped lots with crawl spaces that collect moisture. Sewage odor here often traces back to a slow drain leak rather than a single backup event.
Local Considerations
Wet fall and winter with heavy rain
Saturated ground raises the water table and puts pressure on older drain lines, which is when most Bothell sewage backups happen. Odor calls spike from October through March.
Older housing stock with cast iron and clay drain lines
These lines crack and root-infiltrate over time, causing repeat backups. We often recommend a camera inspection after cleanup so the same problem does not return next season.
Damp crawl spaces under older homes
Crawl space contamination holds odor longer because the space never dries on its own. We run dehumidifiers longer in these homes and treat the soil, not just the surfaces.
Finished basements in newer construction
Carpet, pad, and drywall soak up sewage fast, so more material has to be removed. The upside is that concrete subfloors dry faster than wood once the contaminated material is gone.
Canyon Park Basement Backup
A finished basement took on sewage after a fall rainstorm. The carpet was soaked, the pad was saturated, and the smell had moved into the stairwell and first floor. The homeowner had tried a store-bought cleaner, which did nothing.
We extracted 40 gallons of waste water, removed 600 square feet of sewage-soaked carpet and pad, cut out two feet of contaminated drywall, and disinfected the concrete and framing. Drying ran three days. The smell was gone by day two.
Maintenance & Follow-up
We recommended a camera inspection of the drain line and a backwater valve to prevent the next backup. The homeowner also runs a dehumidifier in the basement each winter.
An upstairs toilet overflowed and sat for a day while the family was away. Water ran through the floor into the ceiling below. The hallway and downstairs room smelled like sewage, and the drywall was soft to the touch.
We pulled the saturated carpet and pad, extracted water from the subfloor, removed the damaged ceiling drywall, and treated the framing with an EPA-registered disinfectant. Drying took four days. Moisture readings returned to normal.
Maintenance & Follow-up
The family now shuts off the water supply when traveling and checks the toilet supply line annually. We replaced the drywall and repainted after the structure was verified dry.
A slow drain leak fed sewage into a crawl space for weeks. The insulation was contaminated, the soil was wet, and the smell had worked its way into the living room above. The homeowner could not find the source on their own.
We removed the contaminated insulation, treated the soil and joists with an antimicrobial solution, and ran dehumidifiers for five days. The leak was repaired, and the crawl space dried to normal readings. The living room smell cleared completely.
Maintenance & Follow-up
We set the homeowner up with a yearly crawl space check before the rainy season and a moisture meter to monitor the space themselves. Catching a leak early keeps the repair small.
How much does sewage odor removal cost in bothell?
Most Bothell sewage odor jobs run $450 to $2,800 in 2026, depending on how far the contamination spread. A single-room toilet overflow with carpet removal sits at the low end. A finished basement with contaminated drywall, soaked flooring, and crawl space work lands at the high end. Insurance often covers the work when the backup is sudden and accidental, and we document the scope so your claim moves.
How do you get rid of sewage smell in a house in bothell WA?
You get rid of it by removing the source, not by covering it up. We pull sewage-soaked carpet and contaminated drywall, extract standing water with a truck-mounted extractor, and treat every surface with an EPA-registered disinfectant. Air scrubbers with HEPA filtration run during drying. In most Bothell homes the smell drops sharply within 24 hours and is gone once the structure reads dry.
What causes sewage odor in bothell homes?
The most common causes we see are sewage backup into a basement, toilet overflow, crawl space contamination, and slow leaks from aging drain lines. Bothell's wet winters make it worse, because damp crawl spaces hold odor and feed mold growth after sewage. If the smell shows up in one room and not another, the source is usually under the floor or behind the wall in that room.

Called about a sewage smell in our basement and they came out the same evening. Found the source in 20 minutes, pulled the wet carpet, and treated everything. The smell was gone the next day. Fair price and no upselling.
We had a crawl space that smelled terrible for months. They removed the contaminated insulation, treated the soil, and dried it out over five days. They showed us the moisture readings each visit. Honest crew and the smell has not come back.
A toilet overflowed while we were out of town and the smell was awful. They handled the cleanup and worked directly with our insurance adjuster. The Xactimate documentation made the claim easy. Would call them again without hesitation.
