Short answer
Before a crime scene cleanup provider arrives, make sure everyone is safe and police have been called, leave the scene undisturbed until investigators formally release it, keep people and pets out of affected areas, avoid cleaning blood or residue yourself, gather the police report number and release time, call your insurer, and ask a victim advocate about support and compensation.
Safety first, then wait for the police release
Safety comes before everything else. If anyone is hurt or in danger, or if you think someone may still be in the building, leave and call 911. Do not go back inside until police tell you it is safe. Medical care for anyone injured is the priority, and cleanup can always wait.
If police are already on scene, follow their instructions. They may ask you to wait outside, to leave the property entirely or to answer a few questions. It can feel frustrating to be kept out of your own home or business, but those first hours matter for the investigation.
Once everyone is safe, take a breath. The next steps are practical, and none of them require you to touch the scene yourself.
Until investigators formally release the property, it is part of an active case. Cleaning, moving items or even opening windows could disturb evidence that detectives need. A professional cleanup company will not start work until the scene is released, and you should not either.
The length of a hold depends on the crime and the agency. A burglary might be processed in a few hours. A serious assault may take longer. Ask the officer in charge how you will be notified, and write down the name, badge number and case number they give you. The investigating agency is the only authority on when your property is released.
If you need medication, a phone charger, documents or clothing while the property is on hold, ask the officers whether someone can retrieve them for you.
Once the scene is released, how do I keep it from getting worse?
After release, the property is back in your hands, but the affected areas still contain biological material and investigative residue. The goal until the cleanup crew arrives is simply to contain the situation, not to fix it.
Close doors to affected rooms where possible. Keep children, pets and visitors away. If it is safe to do so without walking through contaminated areas, you may consider turning off fans or forced-air systems that could carry odors or particles through the home, and asking your provider whether that is appropriate for your situation. Avoid walking through affected areas, since shoes can track material into clean rooms.
- Close off affected rooms and keep them closed
- Keep children and pets in unaffected areas or elsewhere
- Do not walk through stained areas or disturb fingerprint powder
- Leave broken glass or damaged items for the crew
- Secure broken doors or windows with help from a locksmith or glazier if needed
Should I try to clean up blood or fingerprint powder myself?
It is natural to want to erase what happened as quickly as possible. However, cleaning blood without training and protective equipment can expose you to bloodborne pathogens, and scrubbing porous materials like carpet or upholstery often spreads contamination deeper and wider. That can make the professional job larger and harder to document for insurance.
Fingerprint powder is also trickier than it looks. Wiping it with a damp cloth can smear it across walls and fabrics. Professionals use specific techniques for different surfaces.
If a small item you urgently need is in an affected area, ask the cleanup provider to retrieve and clean it first rather than grabbing it yourself.
The same caution applies to broken glass and damaged furniture that may have blood on them. Leave them where they are unless they create an immediate hazard, such as glass on a path children use. In that case, cover the area with a box or board rather than sweeping it up, and point it out to the crew when they arrive.
Documenting the scene without making things worse
Photos can help your insurance claim and your own records, but they are not worth risking exposure or disturbing the scene. Wait until police have released the property. Then, if you feel able, take pictures from doorways and hallways without stepping into stained areas. Wide shots showing each room and closer shots of damaged doors, windows and belongings are usually enough.
You do not have to photograph blood or anything else that would be upsetting to see again. The cleanup provider will document the affected areas in detail during its assessment and can share those images with your insurer. Many people prefer to let the professionals handle that part entirely.
Start a simple written log as well. Note when you discovered the incident, when police arrived, when the scene was released, whom you spoke with and what each person told you. Keep receipts for any immediate expenses, such as a locksmith, board-up service, hotel room or replacement medication. These small records often become important later, and they are much easier to keep from the start than to reconstruct weeks afterward.
If the crime happened at a business, add a note about any employees or customers who were present, any security camera footage you have been asked to preserve and any areas you have closed to the public. Police may request camera recordings, so avoid deleting or overwriting anything until they tell you it is no longer needed.
Details to gather before you call a cleanup company
Having a few details ready makes the first call faster and helps the provider plan. You do not need to describe the scene graphically. Practical facts are enough.
- The property address and the best way to access it
- The police case number and the time the scene was released
- Which rooms or areas are affected
- Flooring and furniture types in those areas
- Whether the property is occupied, and by whom
- Your insurance company and policy number, if known
- Any urgent needs, such as a business that must reopen or children who live there
Does calling after hours change anything?
Some situations genuinely cannot wait until morning, such as a home where a family must sleep that night or a business that serves the public. Others can safely wait a day. If you are unsure, describe your situation honestly and ask the provider whether immediate response is truly needed.
After-hours service can cost more; in its 2025 cost guide, Fixr lists a $500 to $1,000 per-visit surcharge for 24-hour emergency biohazard response. Not every company prices this way, but it is fair to ask whether an emergency charge applies and whether an initial containment visit could be separated from the full cleanup.
If you do need someone right away, ask what they will do on the first visit and what will follow once a full scope is written.
How the first few hours can unfold
Picture how those hours can go for one homeowner. A man comes home late on a Friday to find his front door forced and a neighbor waiting outside. The neighbor saw someone run out, bleeding from a hand. The man calls 911 and waits with the neighbor until police arrive.
Officers clear the house, photograph the damage, dust the door and a jewelry box for prints and release the home around two in the morning. The man writes down the case number and release time. He closes the hallway door, keeps his dog in the backyard and avoids the stained entry rug.
He calls a cleanup company, gives them the case number, the affected areas and the flooring type and agrees to a morning visit rather than paying for an overnight dispatch. A friend helps him board the broken door panel. He calls his insurer's claims line and leaves a message. By mid-morning, a supervisor arrives to assess the scene and write a scope.
This account is illustrative, not a real client's. Your own experience will depend on the incident and the agencies involved.
Other calls to make in the first day
Report the loss to your homeowners, renters or business insurer and write down the claim number. Ask the police or prosecutor's office for a victim advocate, who can explain your rights, help with a victim compensation application and connect you with counseling. If you rent, notify your landlord or property manager.
It is normal to feel shaken, angry or unsafe after a crime at your home or workplace. Ask a friend or relative to stay with you or to let you stay with them. Taking care of yourself is part of taking care of the property.
If the crime happened at work, let your employer or building manager know as well, even if the damage seems limited. They may have their own insurance, security procedures or preferred vendors, and early notice helps everyone coordinate instead of calling different companies at once.
