What to Ask Before Hiring a Crime Scene Cleaner in Alameda County and Santa Clara County

The origins of crime- and trauma-scene cleaning services can be traced back to the 1990s when only a handful of companies operated in this industry. At that time, the field lacked regulation, and awareness of contamination risks was minimal.

"I was young and inexperienced and found myself in a situation straight out of a movie. I quickly took action to assist a woman in her time of dire need, and that's how I entered the crime scene and cleaning business," shared Nick-Anthony Zamucen, Founder of Bio-One Inc.

Today, the landscape has changed dramatically, with hundreds of companies advertising crime and trauma scene cleaning services. However, navigating through this multitude of options during one of life's most traumatic moments can be overwhelming. To help you make an informed decision, we've compiled a list of questions to ask before selecting a crime and trauma scene company.

Questions to Ask Before Hiring a Crime and Trauma Scene Cleaner

When evaluating crime and trauma scene cleaning technicians or business owners, asking the right questions is crucial to finding the best fit for your needs and circumstances.

  1. Are you local? Response time is critical in dealing with blood spills to prevent biohazards from spreading and to ensure swift remediation. Avoid companies with technicians located hours away, and steer clear of toll-free numbers that may lead to call centers. Bio-One Fremont typically responds within 30 to 60 minutes.
  2. Is your business certified and insured? Ensure that the cleaning company holds certifications in handling bloodborne pathogens and follows OSHA guidelines for personal protective equipment (PPE) and remediation processes. Additionally, verify that they are adequately insured to protect both your property and their employees. Bio-One Fremont's technicians are certified in Mental Heath First Aid and trained by by the San Francisco County Department of Mental Health to better communicate with their clients.
  3. What is your process for disposing of biohazardous waste? Proper disposal of biohazardous waste is essential for public health and safety. Verify that the company is familiar with local regulations regarding waste disposal and has a robust plan in place to adhere to these guidelines. Bio-One Fremont is a licensed Trauma Scene Waste (TSW) Management Practitioner with the state of California. (License #806)
  4. What happens to valuable or personal items impacted by the cleanup? A professional cleaning service should be respectful of your possessions, especially items of sentimental or monetary value. Ask how they handle such items and whether they will keep you informed throughout the process. Bio-One Fremont provides clients with a "Property Retention Form". This form helps the highly trained technicians search for valuable items during their cleaning process. The current 2024 list of recovered items includes: Cash ($6,300 and counting), Jewelry (Valued at over $21,000), Pension Documents, Family Trust Plans, Vehicle Titles, Military Pensions, Investment and Banking Accounts and more...
  5. How will you charge for your services? Understand the billing process upfront, particularly if you plan to file a claim with your home insurance. Reputable companies like Bio-One Fremont can assist with insurance claims, alleviating the burden on you. If you're uninsured, request a free line-item estimate to compare costs with other local providers.
  6. Will you prioritize discretion during and after the job? Confidentiality is paramount in sensitive situations. Choose a company that values discretion, such as Bio-One Fremont, whose unmarked vehicles and discreet work practices ensure privacy for you and your neighbors.
  7. Do you provide post-cleanup resources? Beyond cleaning, you may need flooring replaced or fresh drywall installed, which will also be covered under your home insurance claim, and a recommendation could help speed up the reconstruction process. Bio-One Fremont connections with local counselors and victim's advocates. A reputable company should be able to recommend trusted resources to support you through the aftermath.

Above all, ensure that the company you choose demonstrates care and compassion for your situation. Their primary focus should be on providing support and assistance to you and your loved ones during this challenging time.

Girl Upset - Suicide Prevention Resources

According to the American Psychiatric Association, suicide is the 10th leading cause of death in the United States and the second leading cause of death (after accidents) for people aged 10 to 34. And according the CDC, published reports from 2020 suggest that the pandemic has had a negative effect on children’s mental health. 

“Beginning in April 2020, the proportion of children’s mental health–related ED visits among all pediatric ED visits increased and remained elevated through October. Compared with 2019, the proportion of mental health–related visits for children aged 5–11 and 12–17 years increased approximately 24%. and 31%, respectively.”

Researchers have yet to link recent suicides to the pandemic since 2020 suicide data is not yet available. But on the ground, there's growing concern.

The February 2021 NPR article “Child Psychiatrists Warn That The Pandemic May Be Driving Up Kids' Suicide Risk” explores possible correlation. Takeaways include:

  • NPR spoke with providers at hospitals in seven states across the country, and all of them reported a similar trend: More suicidal children are coming to their hospitals — in worse mental states.
  • The number of kids with suicide attempts coming to the emergency room at UCSF Benioff Children's Hospital Oakland, in California, in the fall of 2020 was double the number in the fall of 2019.
  • At Riley Hospital for Children in Indianapolis, the number of children and teens hospitalized after suicide attempts went up from 67 in 2019 to 108 in 2020. And October 2020 saw a 250% increase in these numbers over the previous October.

For ways to help kids at risk, NPR encourages readers to read Part 2 of their story, “Make Space, Listen, Offer Hope: How To Help A Child At Risk Of Suicide”.
