Crime Scene Cleaner Online has spent years building a reputation in Markham for one simple reason: we show up when other services won't. Biohazard scenes — whether from trauma, unattended death, hoarding, or chemical contamination — require more than cleaning.

Situations We Handle
When to Call a Professional Biohazard Crew in Markham
If any of the following conditions exist at your Markham property, professional biohazard remediation isn't optional — it's legally and medically required.
🩸
Blood or Bodily Fluid Exposure
Any visible blood or bodily fluid at a scene falls under biohazardous material classification. Standard cleaning products won't achieve the disinfection levels required by OSHA and ABRA protocols.
💀
Unattended Death or Decomposition
Decomposition produces biogases, volatile compounds, and fluid saturation that can extend several inches into structural materials. Remediation requires material removal, disinfection, and odor neutralization by a certified crew.
🧪
Methamphetamine or Drug Lab Residue
Chemical residue from illicit drug production requires air sampling, surface testing, and systematic decontamination using specific solvents and PPE. This is a regulated process, not a cleaning job.
🚿
Sewage Backup or Category 3 Water
Black water from sewage backups carries E. coli, hepatitis A, salmonella, and norovirus. Without certified Category 3 remediation, the pathogens remain active in flooring and wall cavities long after the water recedes.
🏚
Extreme Hoarding — Biohazard Level
Level 4–5 hoarding scenes present compounding hazards: vermin infestation, structural compromise, mold proliferation, and concentrated bodily waste. Remediation requires a full hazard assessment before a single item is moved.
🏭
Industrial or Commercial Biohazard Spill
A confirmed workplace biohazard exposure in IL triggers OSHA recordkeeping requirements and mandates professional remediation. Our crews carry the documentation to satisfy both OSHA and insurance audits.
Our Services
Every Type of Biohazard Remediation — Serving Markham and Beyond
Our service teams aren't generalists. Each track below has dedicated equipment, specific training certifications, and a documented protocol built around that scene type.
01
Crime Scene & Trauma Remediation
When law enforcement releases a trauma scene, the remediation that follows is regulated work. Our technicians are trained in chain-of-custody awareness, proper handling of biohazardous personal effects, and full restoration of the space to a habitable condition after cleaning and disinfection.
ATP luminescence testing · forensic odor neutralization · full documentation for insurance
02
Unattended Death & Decomposition Cleanup
The timeline between an unattended death and discovery determines the scope of remediation needed. Hours means surface contamination. Days means structural material saturation. Weeks or longer means structural material removal, subfloor extraction, and neutralization of volatile biogases that have migrated through the building envelope.
Our meth lab decontamination process starts with air and surface sampling by a certified industrial hygienist, followed by a systematic decontamination using specific solvents approved for meth residue removal. We handle disposal of all contaminated materials under DOT hazmat regulations and provide documentation for the state health authority in IL.
IH testing & clearance sampling · HVAC decontamination · state-compliant documentation in IL
04
Sewage Backup & Category 3 Water Remediation
Category 3 water — groundwater, sewage, and other grossly contaminated water — is classified separately from clean water or gray water floods precisely because of its pathogen load. Standard water damage restoration companies are not equipped or licensed for Category 3 work. Our Markham crews carry the proper PPE, antimicrobial agents rated for hepatitis and norovirus, and moisture measurement tools to confirm complete elimination of standing contamination.
When a hoarding environment includes animal carcasses, animal or human waste, rotting food, or accumulated biohazardous material, standard junk removal companies aren't an option. Our hoarding remediation teams in Markham are trained in trauma-informed communication, scene hazard assessment, and multi-phase remediation planning that accounts for structural assessment, pest control coordination, biohazard removal, and complete sanitation.
We work directly with facilities managers, property managers, risk management departments, and insurance adjusters in IL to coordinate biohazard incidents from first call through final documentation. Our commercial response team carries multi-liability commercial certificates and can respond to facilities of any size across Markham, IL.

No Surprises — Price First

3
Systematic Scene Decontamination

4

We don't hand over keys and leave. A final walkthrough confirms visual clearance, ATP results are shared with you in writing, and all biohazardous waste manifests are provided for your records.
