What Our Biohazard & Crime Scene Cleanup Service Includes
Crime Scene Cleanup
Crime scene cleanup addresses blood, tissue, and forensic residue left after law enforcement releases a property. In Bothell, we regularly work with King County Sheriff’s Department and Bothell Police to coordinate arrival timing once the scene is cleared. Our technicians remove all biohazardous material, treat surfaces with EPA-registered disinfectants, and document every step with photos that support your insurance claim and personal records.

Trauma & Unattended Death Cleanup
Unattended death scenes present unique challenges in Bothell’s climate, where our cool, damp winters can accelerate decomposition and extend odor penetration into subflooring and wall cavities. We use Injectidry systems and negative air machines to address vapor pressure differentials, the force that drives odor molecules into porous materials, then remove and properly dispose of affected structural elements when necessary. Every unattended death cleanup includes a written scope, a photo record on every visit, and direct coordination with your insurance adjuster.

Hoarding Cleanup
Hoarding environments often conceal biohazards beneath years of accumulation: pet waste, spoiled food, mold colonies, and in some cases, deceased animals. Our Bothell crews work methodically through hoarding cleanups, sorting salvageable items from biohazardous waste with the homeowner or their representative present, documenting each room’s condition before and after. We coordinate with mental health professionals when requested and never dispose of items without explicit written authorization.

Blood & Bodily Fluid Cleanup
Blood and bodily fluid incidents range from accidents in the home to workplace injuries, and Bothell’s mix of residential and light commercial properties means we handle both. We treat all blood as potentially infectious, following OSHA Bloodborne Pathogens Standard protocols with full PPE, double-bagging of waste, and chain-of-custody documentation for medical waste disposal. Surfaces receive a three-stage treatment: cleaning, disinfection with hospital-grade solution, and verification with ATP testing where appropriate to confirm biological load reduction.

Infectious Disease Disinfection
Infectious disease disinfection targets pathogens like C. difficile, MRSA, norovirus, and COVID-19 in homes, businesses, and healthcare settings throughout Bothell. We apply electrostatic sprayers to deliver disinfectant into corners and crevices manual wiping misses, then document treatment areas, contact times, and product concentrations. For commercial clients near the I-405 corridor or in Bothell’s medical office clusters, we provide post-treatment certification for facility records.

Tear Gas & Chemical Cleanup
Tear gas residue, pepper spray, and other chemical irritants penetrate deep into porous surfaces and HVAC systems, causing respiratory irritation long after visible residue is gone. In Bothell, we’ve remediated tear gas contamination in residential properties where law enforcement deployment affected adjacent units, requiring whole-structure assessment. Our process includes surface decontamination, HVAC duct cleaning, air scrubbing with activated carbon filtration, and air quality verification before reoccupancy.

Signs You Need Biohazard & Crime Scene Cleanup Right Now

- Visible blood or bodily fluids on porous surfaces. Carpet, drywall, and unfinished wood absorb biological material within minutes, and household cleaners cannot reach the contamination depth. Professional extraction and treatment prevents bacterial growth and odor penetration that destroys structural materials.
- Persistent odor that returns after cleaning. Biohazard odors indicate material still present, often in subflooring, wall cavities, or HVAC ducts where amateur cleaning cannot reach. In Bothell’s older homes near Main Street, we’ve found odor sources in crawl spaces and between floor joists that previous cleaners missed entirely.
- Law enforcement or coroner has released the scene. Once official investigation concludes, the property owner becomes responsible for all biological remediation, and delays increase contamination spread. We coordinate directly with Bothell Police and King County Medical Examiner to time our arrival appropriately.
- Hoarding conditions with unknown duration or contents. Hoarding environments hide risks that worsen with time: ammonia from pet waste damages respiratory tissue, mold releases mycotoxins, and structural load from accumulated material creates collapse hazards. Our crews assess and document before any removal begins.
- Known infectious disease exposure in the environment. Pathogens like C. difficile form spores that survive standard disinfection and remain infectious on surfaces for months. Professional application with sporicidal agents and documented contact times is required for safe reoccupation.

AfterOur Biohazard & Crime Scene Cleanup Process - Step by Step
- 1
Written assessment and price before work begins. Haven Standard, Clause 1: a technician arrives, documents the scene with photos, identifies all affected materials and areas, and delivers a written price with line-item scope. No work starts until you sign. This is the same process we’ve used on 12,000+ jobs since 2011.
- 2
Containment and engineering controls. We establish negative air pressure using HEPA-filtered air scrubbers to prevent cross-contamination, seal HVAC returns in affected zones, and post warning signage per OSHA and IICRC standards. In Bothell’s multi-family buildings near Beardslee Boulevard, we’ve contained units while neighbors remained in place.
- 3
Removal of biohazardous material and affected structural elements. All biological waste is double-bagged in labeled biohazard containers with chain-of-custody documentation for licensed medical waste disposal. We remove and dispose of carpet pad, saturated drywall, and compromised subflooring, photographing each layer before and after.
- 4
Cleaning, disinfection, and verification. Surfaces receive mechanical cleaning followed by EPA-registered disinfectant application at specified concentration and contact time. Where appropriate, we verify biological load reduction with ATP testing, documenting results in your job file alongside daily photos.
- 5
Final documentation, reoccupancy clearance, and warranty delivery. You receive a complete photo record, waste disposal manifests, treatment logs, and the signed 365-Day Done Right Promise under The Haven Standard. For insurance claims, we provide direct adjuster coordination with documentation formatted for claims review.
How Much Does Biohazard & Crime Scene Cleanup Cost in Bothell?

A typical blood and bodily fluid cleanup in Bothell runs $1,500-$3,500 for contained incidents affecting one or two rooms. Trauma and unattended death cleanup, where decomposition has affected subflooring and wall cavities, typically ranges $3,000-$6,000 depending on structural material replacement needs. Hoarding cleanup varies most widely, from $2,000 for single-room situations to $10,000+ for whole-house environments with extensive biohazard discovery, though most Bothell hoarding cleanups we handle fall in the $3,500-$7,000 range. Infectious disease disinfection for residential spaces generally costs $1,000-$2,500; tear gas and chemical cleanup, which often requires HVAC remediation, runs $2,500-$5,500.
Several factors move these ranges. Square footage of affected area is primary: contamination that has seeped through carpet into subfloor doubles the scope. Material type matters too, hardwood and tile clean differently than carpet and pad, which usually require full removal. Time since incident affects decomposition depth and odor penetration, particularly in Bothell’s cooler months when bodies decompose more slowly but moisture drives mold growth concurrent with biological breakdown. Access issues, crawl spaces, attics, or properties with limited parking near downtown Bothell, add labor hours.
To avoid overpaying, demand a written scope with line-item pricing before work begins, and verify that disposal fees, testing, and documentation are included rather than added later. Haven Standard, Clause 1 exists precisely to prevent the scope-creep additions that plague this industry.
