Crime scene cleanup goes far beyond ordinary janitorial work. Technicians must remove blood, tissue, and other bodily fluids that can carry bloodborne pathogens such as HIV, hepatitis B, and hepatitis C. The process begins with a thorough assessment of the scene to identify all contaminated surfaces, including porous materials like drywall, carpet, and upholstery that may need to be removed and disposed of according to state and federal regulations. Every step follows strict protocols from the Occupational Safety and Health Administration (OSHA) and the California Department of Public Health, ensuring that the area is not only visually clean but also biologically safe for future occupancy. For property owners in Ontario, the stakes are high. Unattended deaths — often discovered days or weeks after the event — can result in advanced decomposition, strong odors, and insect activity that penetrate deep into building materials. Crime scene cleanup in these cases involves the use of industrial-grade disinfectants, HEPA vacuuming, and sometimes ozone treatment to eliminate airborne contaminants. The goal is to restore the property to a condition that is safe for family members, tenants, or buyers to re-enter. Because Ontario has a mix of residential neighborhoods, commercial properties, and rental units, prompt and thorough cleanup helps prevent further damage, legal liability, and emotional distress for those who must deal with the aftermath. This work is not about aesthetics; it is about public health and the dignity of the space. ## Areas We Cover in Ontario Our crime scene cleanup services extend throughout Ontario and its surrounding communities.
