What You Need to Know About Crime Scene Cleanup
Crime scene cleanup is the professional removal of blood, bodily fluids, and other biological hazards left behind after a traumatic event. Here’s a quick overview:
| Topic | Key Facts |
|---|---|
| Who does it | Licensed biohazard remediation companies |
| Who pays | Property owner, homeowners/renters insurance, or victim compensation programs |
| How long it takes | Usually 1–2 days depending on severity |
| Can you DIY? | No — it is dangerous and may violate regulations |
| 24/7 availability | Most professional companies respond around the clock |
When emergency responders leave a scene, the burden of cleanup falls on the property owner — not law enforcement. That silence after police and ambulance vehicles drive away can be overwhelming, especially for commercial property managers who need spaces restored quickly and safely.
Crime scene cleanup is not ordinary cleaning. It involves exposure to bloodborne pathogens like HIV, Hepatitis B, and Hepatitis C. It requires specialized training, proper protective equipment, and strict compliance with OSHA and EPA regulations. Attempting it without professional help puts people at serious risk.
California alone averages nearly 3,000 homicides per year. Across the country, thousands more suicides, unattended deaths, and industrial accidents create urgent cleanup needs every single day.
I’m Terry Zastrow, owner of ZBM Inc. — an IICRC-certified firm with approximately 30 years of experience providing crime scene cleanup and biohazard remediation services to state agencies, municipalities, and private-sector clients in Wisconsin. In the sections below, I’ll walk you through everything you need to know to handle these situations safely and confidently.

What is Crime Scene Cleanup and Who is Responsible?
When a traumatic event occurs on a property, many people assume that the responding police department or forensic unit will handle the aftermath. In reality, once law enforcement finishes documenting evidence and releases the scene, their job is done. They pack up their yellow tape and leave, leaving the property owner with the daunting and emotionally draining task of restoring the space.
This is where professional biohazard remediation, commonly referred to as forensic cleanup or crime scene cleanup, comes into play. It is a highly specialized industry dedicated to the safe removal of blood, bodily fluids, tissue, and other potentially infectious materials (OPIM) from residential, commercial, and industrial properties.
At ZBM Inc., we understand that the responsibility of cleanup falls squarely on the shoulders of the property owner. Whether you are a grieving family member or a commercial property manager in Watertown, WI, trying to keep your business running, you do not have to carry this heavy burden alone. You can learn more about how we help by exploring More info about trauma cleanup teams.
Our primary goal is to protect people from dangerous bloodborne pathogens and restore peace of mind. Regular household cleaning supplies simply cannot eliminate the microscopic pathogens that thrive in biological waste. Without the proper chemicals and techniques, you risk spreading the contamination further. For a deeper understanding of how these hazardous situations are managed alongside other property emergencies, check out our Guide to biohazard and fire cleanup.
Situations Requiring Professional Crime Scene Cleanup
Professional remediation is necessary in several distinct, high-risk scenarios:
- Homicides and Violent Crimes: These situations often involve significant blood splatter and structural contamination.
- Suicides and Attempted Suicides: These tragic events require extreme sensitivity, rapid response, and deep sanitization.
- Unattended Deaths (Decomposition): When a person passes away and is not found for days or weeks, natural decomposition occurs. Biological fluids can quickly saturate carpets, subfloors, and even seep into the rooms below.
- Industrial Accidents: Severe workplace injuries or fatalities that involve heavy machinery require rapid, compliant sanitation to protect remaining staff and minimize business downtime.

Every single one of these scenarios requires specialized tools, commercial-grade disinfectants, and highly trained technicians. If you are located in the Jefferson County area, you can access localized assistance through our dedicated trauma and crime scene cleanup services in Lake Mills, WI.
Health Risks, Regulations, and Certification Requirements
The primary reason why general cleaning staff or homeowners should never attempt crime scene cleanup is the sheer volume of health risks involved. Human blood and bodily fluids can carry deadly, invisible pathogens. These include:
- Hepatitis B (HBV): A highly resilient virus that can survive in dried blood on surfaces for up to a week.
- Hepatitis C (HCV): A bloodborne virus that causes chronic liver disease.
- Human Immunodeficiency Virus (HIV): The virus responsible for AIDS.
- Infectious Bacteria and Fungi: Especially prevalent in decomposition cases, where airborne bacteria and overpowering odors present severe respiratory hazards.
Because of these extreme dangers, federal and state agencies heavily regulate the biohazard remediation industry. The Occupational Safety and Health Administration (OSHA) enforces strict standards, including the Bloodborne Pathogens Standard (29 CFR 1910.1030). This standard mandates that any worker exposed to blood must have comprehensive training, a formal exposure control plan, and access to personal protective equipment (PPE).
If you are interested in the professional side of this industry, including how we train our staff to meet these rigorous standards, read our guide on How to break into the biohazard business.

State-Specific Regulations and Reimbursement Limits
While we primarily serve our local communities in Southeast Wisconsin, it is helpful to look at how different states regulate and fund these services. Different states have unique agencies and compensation boards set up to assist victims of violent crimes with the financial burden of cleanup.
| State | Regulatory Authority / Licensing Agency | Maximum Victim Compensation Limit | Key Regulatory Detail |
|---|---|---|---|
| Wisconsin | Wisconsin Department of Health Services | Varies by program / insurance | ZBM Inc. is fully licensed, bonded, and insured to serve Southeastern WI. |
| California | California Department of Public Health | Up to $1,709 (CalVCB) | Cleanup must be performed by a registered Trauma Scene Waste Management Practitioner. |
| Florida | Florida Department of Health | Up to $2,250 (CVC Program) | Permits companies as biomedical waste generators/transporters; does not directly regulate cleanup methods. |
For families dealing with the aftermath of a crime, these state-funded victim compensation programs can be a financial lifesaver, helping to offset the out-of-pocket costs of professional restoration.
Training and Certifications for Crime Scene Cleanup
To safely navigate these hazards, professional technicians must hold industry-recognized certifications. The gold standard for trauma scene restoration is the ANSI/IICRC S540 Standard for Trauma and Crime Scene Cleanup. This standard outlines the scientific principles and field-tested practices required to safely clean, sanitize, and verify the safety of a contaminated environment.
Key certifications and training programs include:
- ABRA (American Bio Recovery Association): Offers rigorous credentialing levels for bio-recovery technicians.
- HAZWOPER (Hazardous Waste Operations and Emergency Response): Essential training for handling chemical and hazardous materials.
- OSHA Bloodborne Pathogen Certification: Annual training focusing on cross-contamination prevention and PPE compliance.

The Professional Cleanup Process and Biohazard Disposal
At ZBM Inc., we follow a highly systematic, multi-tiered process to ensure that a contaminated property is returned to a safe, livable state. We treat every biological spill with “universal precautions,” meaning we assume every drop of fluid is infected with transmissible pathogens.

Our technicians wear full-body, liquid-impermeable suits, heavy-duty gloves, boot covers, and full-face respirators. We establish strict containment zones using plastic barriers to prevent the cross-contamination of unaffected areas.
One of the most critical aspects of our work is identifying hidden contamination. For example, a tiny, dime-sized blood spot on a carpet often masks a massive, two-to-three-foot pool of fluid that has soaked through the carpet pad and saturated the wooden subfloor beneath. We use specialized chemical reagents and high-intensity bio-illuminators to detect hidden splatter on walls, behind baseboards, and inside electrical outlets.
We also use ATP (Adenosine Triphosphate) testing to verify cleanliness. This scientific test measures organic cellular activity on a surface, giving us quantifiable proof that all biological matter has been successfully eradicated. For a straightforward breakdown of these procedures, refer to our Quick start guide to clean crime. If you reside in Dodge County, you can find our localized biohazard cleanup services available 24/7.
Step-by-Step Remediation Timeline
While every scene is unique, a typical professional cleanup follows a structured timeline:
- Step 1: Rapid Assessment & Estimate (Hours 1–2): We perform a detailed walkthrough to determine the scope of work, identify structural damage, and provide a transparent estimate.
- Step 2: Containment & Isolation (Hours 2–3): We seal off the affected areas and set up air scrubbers to control odors and airborne pathogens.
- Step 3: Biohazard Removal (Hours 3–8): We carefully remove and package all heavily saturated, unsalvageable materials (like carpet, padding, and drywall) into federally approved biohazard disposal boxes.
- Step 4: Sanitization & Deodorization (Hours 8–24): We apply commercial-grade, EPA-registered disinfectants using a three-tiered chemical system to destroy bacteria, viruses, and fungi. We then use specialized equipment to permanently neutralize lingering odors.
- Step 5: Verification Testing (Hour 24+): We conduct ATP testing to guarantee the space is 100% safe for occupancy.
If you are located in Jefferson County, we can quickly dispatch teams to your property to handle any crime scene cleaning needs.
Insurance Coverage, Discretion, and Finding Help
One of the most common questions we receive is: How are we going to pay for this?
Fortunately, in the vast majority of cases, homeowners, renters, or commercial property insurance policies will cover the cost of professional crime scene cleanup. Insurance companies recognize that biohazards present a legitimate structural and safety risk to the property.
At ZBM Inc., we work directly with your insurance provider to make the process as stress-free as possible. We document the entire cleanup process with detailed photos, itemized lists of damaged materials, and official disposal receipts to ensure your claim is processed smoothly.
Beyond the technical cleanup, we understand the immense emotional toll these situations take on families and business owners. We prioritize discretion above all else. Our teams arrive in unmarked vehicles, and we maintain strict confidentiality, never speaking with the media or curious onlookers. We focus on helping you get through one of the hardest days of your life with dignity and respect.

Frequently Asked Questions about Biohazard Remediation
Does homeowners insurance cover the cost of crime scene cleanup?
Yes. In most situations, standard homeowners and renters insurance policies cover the cost of professional biohazard remediation. The cleanup of blood and bodily fluids is typically treated as a property damage claim. We can work directly with your insurance adjuster, submitting all required documentation and photos to minimize your out-of-pocket expenses.
How long does the cleanup process typically take?
The majority of professional cleanups are completed within 24 to 48 hours. However, the timeline depends on the severity of the scene. For instance, an unattended death decomposition that has affected structural subfloors or drywall may take longer, as we must carefully remove contaminated building materials to permanently eliminate deep-seated odors and biological fluids.
Can I clean up a crime scene myself?
We strongly advise against this. Cleaning a trauma scene yourself exposes you to dangerous bloodborne pathogens like Hepatitis B and C, which can survive outside the body for days. Furthermore, standard household cleaning products are not powerful enough to fully sanitize the area, and improper disposal of biohazardous waste is illegal in many jurisdictions. Finally, the emotional trauma of cleaning up after a loved one can leave lasting psychological scars.
