Homicide Cleanup
Homicide cleanup of blood, tissue and contaminated materials after investigators leave.
See homicide cleanupGet blood, body fluids, fingerprint powder and odor removed from a home, apartment, rental or business in Cambridge once police release the property. Most crime scene cleanups take one to three days.
Crime scene cleanup, also called forensic cleaning or trauma scene cleanup, is the removal of blood, body fluids, tissue and contaminated materials after a violent crime, then disinfection and odor removal so the property is safe to use again.
It starts where the investigation ends. Police, detectives and the medical examiner collect evidence and remove the deceased, but they do not clean. The scene is released to the property owner, the family or the landlord, and the cleanup becomes their responsibility.
Crime scene cleaners, also called forensic cleaners or a forensic clean up crew, treat every drop of blood as infectious. They trace how far it traveled, remove what cannot be disinfected, clean and treat every surface, and haul the hazardous materials away under medical waste rules. It is a form of biohazard remediation, and the cleanup process covers these steps from start to finish.

You can call during the day or overnight, and unmarked vehicles help keep the situation private from neighbors.
You can take the work scope, disposal documents and photographs to landlords or insurance companies and move forward.
Keepsakes, photos and documents are set aside and reviewed with you, never thrown out without asking.
You hear the cleanup steps and what affects the price before any work starts, so you can make the right decision for your family.
You may need crime scene cleaning services whenever blood or body fluids remain after a violent event. Typical situations include:
Commercial crime scene cleanup in offices, stores and warehouses, with work areas isolated during cleaning.
Tissue and blood may affect furniture, walls and flooring across multiple rooms.
Tear gas or pepper spray residue on walls, fabrics and HVAC ductwork after a standoff.
Ceilings and walls may have blood spatter, and the carpet and subfloor beneath a person may be saturated.
The first hours matter for your health, your insurance claim and the final cost. Before the cleanup technicians arrive:
Call (888) 351-0904Most residential crime scene cleanup costs between $1,500 and $7,500. Published cost guides show this range. Companies generally set a price for the whole job rather than charging by the hour. Surface blood limited to a small area may cost less. When several rooms or the subfloor are affected, costs may exceed $10,000. An on-site assessment determines the final price.
These ranges come from published national cost guides, not from a site visit. The price for your property is set after the on-site assessment, and you hear it before work starts.
Ask about cost: (888) 351-0904Your policy controls whether crime scene cleanup has coverage. A homeowners or renters policy might classify the event as accidental and sudden, with a possible deductible.
Your homeowners or renters policy terms determine coverage following a violent crime. Make the event report quickly, then write down your claim number.
The Massachusetts Office for Victim Assistance runs a Victim Compensation Program that lists crime scene cleanup among covered expenses for victims of violent crime. Insurance is usually checked first.
Property owners typically pay for and organize crime scene cleanup in shared areas and rental homes.
Ask whether biohazard cleanup is covered, whether you can choose the cleanup company and what photos or records the adjuster needs.
Differences between crime scenes do not change the safe order of the work. Often described as the remediation process, crime scene cleanup proceeds step by step, beginning with the first walk-through and ending at final inspection.
You or your representative walks through the area with technicians, who document it in photos and settle the scope before cleaning begins.
Technicians put on full personal protective equipment, then contain the affected area using plastic sheeting and negative air.
Crews cut away soaked mattresses, furniture, carpet, pad and drywall, then bag and seal them as medical waste.
All surfaces receive cleaning followed by an EPA-registered hospital-grade disinfectant applied for the full contact time.
Odors are addressed where they begin with air scrubbers, ozone or hydroxyl machines, while HVAC vents receive inspection.
Tracking documents accompany closed containers to a medical waste facility that is permitted to receive them.
You receive records and photos for the claim, and technicians can use ATP testing to check surfaces.
After the affected materials are removed, your chosen contractor or an insurer-selected vendor can install new flooring and drywall.
You can call anytime. You speak with a crime scene cleanup specialist who outlines the process and schedules a start time with you.
Serious health risks can come from blood and bodily fluids, including contamination beyond what you are able to see.
Carpet does not stop blood from reaching the pad and subfloor, while grout and spaces under baseboards can trap it. Surface cleaning leaves it there, where odor and bacteria come back.
Medical waste rules apply to soaked materials. They cannot go in household trash or a dumpster, and must go to an approved treatment facility.
Blood can contain HIV, hepatitis C and hepatitis B. According to the CDC, hepatitis B remains viable on surfaces for at least seven days, including when blood appears dry.
Can you clean it yourself? Wear gloves and apply an EPA-registered disinfectant when fresh blood is limited to a few drops on any hard, non-porous surface. Anything that reached fabric, carpet, wood or drywall, or any amount you cannot see the edges of, needs professional cleanup.
For most crime scene cleanups, time at the property is one to three days. A recent scene with a small affected area can take a day, while structural removal at a heavy scene can extend the work to two to five days.
| Scene | Typical time on site |
|---|---|
| Light scene, one area | Often one to two days |
| Typical scene, one to two rooms | Often one to three days |
| Several affected rooms or a subfloor removal | Often two to five days |
Odor removal begins by taking away its source. If fragrance is sprayed over tissue or blood, the smell is hidden for only a few days.
After the contaminated materials are gone, the cleanup team can use HEPA air scrubbers to capture particles, hydroxyl generators that are safe to run while people are present, and ozone treatment in empty rooms for stubborn odor. Thermal fogging reaches odor in fabrics and wall cavities, and HVAC ductwork is checked so smell does not travel to other rooms.
Federal rule 29 CFR 1910.1030 sets requirements for protective equipment, training and handling whenever workers can be exposed to blood.
Disinfectants used on blood should be registered by the EPA and left on the surface for the full contact time on the label.
Massachusetts calls this medical or biological waste, and it includes materials saturated with blood. Department of Public Health rules control its storage, treatment, disposal and transportation, so it must be treated first and cannot go in household trash.
Massachusetts uses a statewide system. The Office of the Chief Medical Examiner, under the Executive Office of Public Safety and Security, investigates violent, suspicious or unexplained deaths. Cleanup starts after police or the medical examiner release the scene.

Planning for access, containment and cleanup can depend on local population, housing and entry conditions.
The 66.5% renter share means many cleanup calls may involve lease responsibilities, building access, and approval from more than one person.
Because the median home dates to 1950, cleanup planning should account for older finishes that may not tolerate heavy moisture.
About 5,500 older residents live alone in Cambridge, representing 39.5% of seniors and making regular welfare checks especially meaningful.
Because just 16.3% of housing is single-family, cleanup may require protecting elevators, corridors, and neighboring occupied areas.
You can ask about cleanup in nearby communities and ZIP codes during the call.

Published guides say most home crime scene cleaning costs range from $1,500 through $7,500. Limited surface cleaning can fall below the usual range, and major multi-room scenes can cost more than $10,000.
Most crime scenes require one to three days of on-site cleaning. A light scene can be done in a day and a heavy scene with subfloor removal can take up to five days.
Law enforcement and the medical examiner remove evidence and the deceased without cleaning the property. The family, landlord or property owner generally arranges crime scene cleanup through professional crime scene cleaners.
Your homeowners or renters policy terms determine coverage, and you may have a deductible. Notify the insurance company, then ask if biohazard cleanup is included in your coverage.
