Crime Scene Cleanup
Crime scene cleaning begins after police release and covers blood, odor and the affected property.
See crime scene cleanupGet blood, bodily fluids, contaminated materials and odor removed after investigators release a home, rental, business or vehicle in Rockingham County. The cleanup scope is based on where contamination traveled.
Homicide cleanup is specialized crime scene work performed after investigators complete their duties and release the property. It removes bodily fluids, blood and other contaminated materials.
While the medical examiner and law enforcement concentrate on investigative duties, they do not clean what remains at the property. Homicide cleaning can be arranged after release of the scene by an authorized person, including an owner, landlord or relative.
The cleanup process goes beyond ordinary cleaning services. Cleanup technicians locate contamination in the affected area and surrounding areas, protect unaffected rooms, remove materials that cannot be disinfected and treat cleanable surfaces. The work also includes hazardous waste packaging, waste disposal, odor removal and records for an insurance company when requested.

Ask which materials can be cleaned, which need removal, how waste exits the site and what the restoration stage will include.
You can request unmarked vehicles and limit entry to authorized people, which helps protect privacy during a painful event.
You are consulted about recoverable personal property after it is isolated and before a removal decision occurs.
Disposal records, scope details, photos and item lists can help when you speak with insurance companies or property owners.
When blood or other biological material remains after a violent death, a home, vehicle, rental or business may require homicide cleanup services. Common examples are:
An assessment of seats, insulation, trim and carpet identifies what may remain after cleaning and what needs removal.
Tracing the entire path is necessary when tissue and blood can reach carpet, walls, furnishings, ceilings or concealed joints.
The landlord or an authorized property manager may schedule scene cleanup once police release the rental and essential items have been taken by the family.
A visible blood mark can extend beneath flooring and behind trim, so wiping only the surface is insufficient.
Respect for the investigation comes first. You should also avoid exposure and retain details that may be useful for a claim. Before cleanup technicians enter, take these steps:
Call (888) 440-9227Available homicide cleanup cost guides put violent crime scenes in the $2,500 to $9,000 range. They place smaller scenes in a range from $2,000 to $6,000 and larger scenes between $3,000 and $10,000 based on their published figures. These are planning ranges rather than a quote. An assessment determines the final scope.
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) 440-9227Homicide cleanup may be paid through a renters, homeowners or commercial policy. Whether it applies depends on the specific loss, policy terms and deductible.
After the scene is released by police, inform the insurer about the loss. Ask about policy coverage for biohazard cleanup, affected construction materials and the restoration phase.
Have the insurance company identify every needed invoice, photo, item list, disposal record and scope note. Make copies of all materials before submission.
The lease, local law, property ownership and policy terms can affect who arranges work and who pays. Landlords and tenants should contact their insurers.
Victims of crime can ask the New Hampshire Attorney General's Victims' Compensation Program whether cleanup costs can be included in a compensation claim. Insurance is usually checked first.
The remediation process follows a controlled order after scene release. Every step is based on where contamination traveled, which materials can be saved and what waste rules apply.
The authorized person identifies known affected areas, and technicians inspect nearby surfaces, floor edges, contents and possible travel paths.
Clean rooms are kept apart from the work area. Cleanup technicians rely on proper personal protective equipment and containment controls to keep contamination from being tracked past the scene.
Before detailed cleaning and disinfection, visible bodily fluids and blood are gathered using a method appropriate for each surface.
The smallest practical sections of upholstery, subfloor, carpet, padding or drywall are removed when complete disinfection is not possible.
Cleanable materials undergo detailed scene cleaning before an EPA-registered disinfectant is applied and stays wet throughout the label contact time.
Targeted treatment and air filtration can address odors in connected spaces, room air and retained materials once the source has been removed.
Contaminated waste is sealed, labeled and moved according to applicable rules, with disposal records retained when available.
Once work is complete, retained personal property is returned as arranged, and removed finishes are documented for restoration services.
You can call anytime. A specialist in homicide cleanup takes your call, explains each step and agrees on a start time with you.
Serious health risks may remain in bodily fluids, blood and contaminated material out of sight. Those risks can still be present if the visible spot appears dry or limited.
Blood may contain HIV, hepatitis B or hepatitis C. Dried blood must still be controlled carefully because the CDC says hepatitis B survives on surfaces for at least seven days.
Wall cavities, subfloor, padding, grout and seams can absorb fluids. Cleaning the visible mark does not address material below or behind the surface.
For family and loved ones, the scene may be very distressing. Professional cleanup lets family members avoid direct contact with the affected space and personal property.
Can you clean it yourself? A small amount of fresh blood on a hard, non-porous surface may be cleaned with disposable gloves and an EPA-registered disinfectant used for its full label contact time. Seek professional cleanup and keep away whenever blood reaches fabric, carpet, drywall, wood or a location with unknown edges.
Blood-absorbing porous materials generally must be taken out. A non-porous surface can often stay if the entire exposed portion can be reached and disinfected.

The time required for homicide cleaning depends on how large the scene is, how deep contamination went, how many rooms are involved, available access and how much material needs removal. A useful schedule can be discussed following the initial assessment.
| Scene | Typical time on site |
|---|---|
| Limited affected area with accessible surfaces | Timeline determined once the scene is released and inspected |
| One affected space containing absorbent materials for removal | May involve cleanup followed by restoration as another phase |
| Several rooms or structural contamination | Often involves a phased cleanup scope and extended restoration |
Finding the odor source and taking it out is the first step. Fragrance does not fix fluids that have soaked into furniture, carpet, drywall, subfloor or concealed cavities.
Once contaminated materials are gone, airborne particles can be filtered with HEPA air scrubbers. Hydroxyl treatment is an option for occupied spaces when permitted by equipment instructions. Ozone treatment needs an empty area and strict controls. Before you proceed, the cleaning process may also involve inspecting neighboring rooms and vents.

Planning for access, containment and cleanup can depend on local population, housing and entry conditions.
In Derry, 40.9% of homes are renter occupied, so privacy and simple communication matter when a property contact is involved.
Local housing centers on 1982, making inspection beneath finished surfaces important when contamination extends past the visible area.
The 1,116 seniors living alone may need support from relatives or trusted contacts when a cleanup decision follows a medical emergency.
Single-family homes represent 53.3% of housing in Derry, creating a mix of detached properties and buildings with shared spaces.
Ask on the call about cleanup options for neighboring communities and ZIP codes.

At the source, death odor removal uses air scrubbers plus hydroxyl and ozone treatment.
See death odor removalCleaning it yourself is inappropriate if blood reached an unseen space or absorbent materials such as carpet, drywall, furniture, fabric or wood. Bloodborne pathogens and hidden contamination may lead to serious health risks. Keep people and pets away, wait for scene release and arrange professional cleanup for any affected area whose full boundary is unclear.
Unaffected items can remain under protection or be moved away from the contaminated zone to a clean location. Scene property is evaluated item by item. Cleaning may work for hard, non-porous items. Absorbent items may need removal, while photos, documents and keepsakes should be discussed with you before a decision is made.
For violent crime scene work, the published homicide cleanup cost is $2,500 to $9,000. While the smaller range is $2,000 to $6,000, costs for a larger scene are listed at $3,000 to $10,000. Affected area size and depth, involved rooms, disposal and police clearance shape the final scope.
Yes, separate hazards may exist at the same property. Heavy accumulations may be addressed through hoarding cleanup services once evidence restrictions have ended. Sewage cleanup may be needed after a sewage backup, and water damage may require drying. Containment, disposal and the cleaning process must each be planned for the specific hazard.
Some or all covered expenses may be paid after the deductible, although terms vary for every policy and every situation. When reporting claim details, ask the insurance company about biohazard cleanup, emergency response work, structural materials and restoration. Store copies of photographs, scope documentation, invoices and disposal papers.
A homeowners policy might pay for homicide scene cleanup or death cleanup, but coverage varies according to policy language, exclusions, the event and the deductible. Contact the insurer before work begins. Ask the insurer about required documentation, biohazard cleanup, damaged materials, personal property and restoration before work starts.
You can request respectful, discreet homicide cleanup 24 hours a day, and crews use unmarked vehicles.
