Biohazard cleanup in Seattle covers crime scenes, deaths at home and hoarded homes across King County.
In Seattle, 51% of homes are in buildings with five or more units, against 37% across King County.
The short answer for Seattle
Biohazard cleanup in Seattle costs different amounts for every job, because the price depends on how large the affected area is, what material was soaked, and how much has to be removed rather than cleaned. A written estimate after an on-site assessment is the only reliable figure, and anyone who quotes a flat price over the phone is guessing.
The type of job matters first. Blood and bodily fluid cleanup in one room is smaller than unattended death cleanup, where fluids may have reached the subfloor. Hoarding cleanup is priced by the volume of material, the paths that must be cleared and any contamination underneath.
Housing in Seattle shapes the scope. According to Census estimates, 51% of homes are in buildings of 5 or more units, compared with 22% statewide, and 56% of homes are rented. In an apartment, a leak can pass through flooring into a neighboring unit, so the work may extend past one room. Renting also changes who handles the bill. A tenant's family, the landlord and a property manager each have a stake, and a landlord's policy may cover part of the work, so it is worth asking before anything is signed.
Older construction adds to what comes out. Census figures show 39% of Seattle homes were built before 1960, against 21% across the state. Older carpet, wood subflooring and plaster hold fluids more deeply and are more often torn out than wiped down.
For an executor, the practical step is to photograph nothing inside, keep the space closed and ask for itemized estimates. The same applies to crime scene cleanup in Washington, where a reputable estimate lists labor, disposal and materials separately.

Not a quote: typical 2026 national ranges from published cost guides (Fixr, HomeGuide and Yelp cost guides, read 12 October 2026). Your price depends on what happened, how long the scene went unattended, how far contamination spread into floors, walls and the heating and air system, and the volume of regulated waste.
Local facts for King County
- 56% of homes in Seattle are rentals, against 36% across Washington, so a landlord is often part of the call.

- 33% of residents 65 and older in Seattle live alone.
The basics
Biohazard cleanup is priced by the job. Crews are billed by the hour, regulated medical waste by the pound, and materials that soaked through are removed and listed in the written scope.
Two jobs of the same kind can differ by thousands of dollars: how far the contamination spread, how long it sat, and how much has to be cut out decide the total.
Biohazard waste rules that apply in Seattle
Washington has no statewide license for general biohazard cleanup; companies that remove or repair building materials during a job must register as contractors with the Department of Labor and Industries, companies that decontaminate former drug lab sites must hold a Department of Health clandestine drug lab decontamination contractor certificate (RCW 64.44.060, chapter 246-205 WAC), and companies that haul biomedical waste for pay need a Utilities and Transportation Commission certificate. Look up any registration at Washington L&I.
Seattle households and this question
Cost depends on the size of the affected area, how long the situation went unnoticed, and what materials were soaked. Seattle's own figures point to a few things that tend to shape the work.
According to Census estimates, 41% of Seattle households are one person, compared with 31% in the county and 27% in the state. In a home where someone lives alone, a problem can go unnoticed longer, and a longer wait usually means more materials to remove. Unattended death cleanup in these homes often involves flooring and subfloor, which raises the scope of work.
Housing matters too. Census estimates show 51% of Seattle homes are in buildings of 5 or more units, against 22% statewide, and 39% were built before 1960, against 21% for the state. In an apartment, contamination can reach neighboring walls or shared plumbing. An older building may have layered flooring and old wall materials that need extra care.
CDC PLACES estimates put frequent mental distress among Seattle adults at 15.7%, against 14.0% in the county. For families dealing with suicide cleanup, the first call is often the hardest part. If you or someone close to you is struggling, call or text 988, the Suicide and Crisis Lifeline.
To get a firm number, describe the space and how long it has been affected, then ask for a written scope before any work begins. A policy may cover part of the cost, so ask your insurer what applies.

What King County callers ask
How much does biohazard cleanup cost in Seattle?
Published cost guides give national ranges rather than city prices. A typical home biohazard job runs $1,500 to $5,000 in the Fixr, HomeGuide and Yelp guides, and standard-risk technicians bill $25 to $150 an hour. A job in Seattle follows the same drivers: what happened, how long it went unnoticed, how far it spread and how much waste has to go. Ask for the scope and price in writing before work starts.
How much does biohazard cleanup cost per hour?
According to Fixr and HomeGuide (2026), standard-risk biohazard technicians bill $25 to $150 an hour and high-risk pathogen work runs $50 to $600 an hour. Fixr lists crime scene and after-death crews at $400 to $600 an hour, unattended death crews at $200 to $300 an hour and odor control at $75 to $100 an hour. Regulated waste disposal is billed separately, at $2 to $20 a pound.
Why does decomposition increase cleanup costs?
Because more has to be removed. The longer a death goes unnoticed, the further fluids soak into flooring, subfloor, walls and furniture, and more of it has to be cut out, bagged and hauled as regulated waste, which is billed by the pound. Odor treatment also takes longer, sometimes several days of air scrubbers. Heat speeds all of it up, so the season matters as well as the time.
What could change the final cost?
Contamination found under flooring or behind walls once work starts is the most common reason. More waste than expected, a call-out at night or on a weekend, which Fixr (2026) prices at $500 to $1,000 a visit, and rebuilding after the cleanup also change the total. Ask the company in writing what the price includes, what would change it and how you will be told before extra work is done.
How much does hoarding cleanup cost?
According to HomeGuide, Yelp and Fixr (2026), a typical hoarding cleanup with no biohazards costs $1,000 to $4,000, and HomeGuide gives about $1 to $2 per square foot. Hauling adds $150 to $350 per load, and biohazards such as human or animal waste add $1,500 to $5,000. The size of the home and how much has to be sorted set the total, so ask for the scope and price in writing.
