Overview

Crime Scene Cleaning- what it is, who it's for.

What it is

Crime scene cleaning - properly called trauma scene biohazard restoration - is the controlled decontamination of a property after a violent incident, suicide, undiscovered death, or other event involving the release of blood, bodily fluids or biological material. Police forensic teams do not clean the scene; that legal and practical responsibility falls to the property owner or family, and it requires certified biohazard protocols.

Who it's for

We are called by families immediately after police release a scene, by landlords whose tenants have been involved in an incident, by housing associations responding to community trauma, by insurers and loss adjusters coordinating claim responses, and occasionally by employers handling workplace incidents. Every call is handled in confidence and without judgement.

When to call

The scene becomes our responsibility as soon as Merseyside Police, Cheshire Police or the relevant authority hands it back. Speed matters - biological material denatures rapidly, porous surfaces absorb contamination, and decomposition products penetrate plasterboard, sub-floor and joists within hours. We mobilise crew within 2–4 hours of release, 24/7.

Why professional matters

Untrained cleaning of a trauma scene is dangerous (bloodborne pathogens - HIV, hepatitis B and C, prion diseases - remain viable for hours to days), legally exposing (improper biohazard disposal is a Hazardous Waste Regulations offence), and almost always emotionally devastating for family members. Specialist crews exist so that families and landlords do not have to do this themselves.

What Happens If It's Left

The cost of delayis rarely the cost you see.

What people don't realise about trauma scenes is how quickly the situation worsens - and how invisible the worst of it becomes.

  • Bloodborne pathogen exposure

    Hepatitis B remains infective on dry surfaces for up to seven days. HIV, hepatitis C and a range of bacteria are present in any biological release. Domestic cleaning products do not deactivate them.

  • Sub-surface contamination

    Blood and fluids penetrate carpet underlay, sub-floor, plasterboard skirting and tile grouting within hours. Surface-only cleaning leaves the contamination in place - it just becomes invisible.

  • Decomposition odour

    Undiscovered death scenes generate volatile organic compounds (cadaverine, putrescine) that bind to plasterboard, paint and fabric. Standard air fresheners mask the odour for hours, then it returns - properties are sometimes uninhabitable for months without proper remediation.

  • Legal disposal exposure

    Trauma waste is Category B hazardous waste under HW Regulations 2005. Disposal in domestic bins is a criminal offence and routinely results in prosecution and tracing back to the source property.

  • Family trauma

    Family members who attempt to clean a scene themselves frequently develop acute stress reactions and post-traumatic symptoms. This is not a job that can be done while grieving, and it should not be expected of anyone.

Our Process

A defined sequence.Documented at every step.

  1. STEP 01

    Confidential 24/7 Call

    Direct line to Shaun, day or night. We confirm property access, incident type (broadly), scene release status and family / landlord contacts.

  2. STEP 02

    Mobilisation

    Crew dispatched within 2–4 hours of scene release across the Wirral, Liverpool and Cheshire. Two-person team minimum, full PPE and RPE, biohazard containment kit.

  3. STEP 03

    Scene Assessment & Containment

    Affected area is sealed from the rest of the property. Photographs taken for the evidence pack (with sensitivity). Affected surfaces and substrates assessed for porosity and penetration.

  4. STEP 04

    Removal & Decontamination

    Saturated soft materials (carpet, underlay, mattresses, plasterboard) are removed under Category B hazardous waste protocol. Hard surfaces are HEPA-vacuumed and treated with EN 14476-certified virucidal disinfectants.

  5. STEP 05

    Odour & Air Remediation

    Where decomposition odour has penetrated, we use ozone or hydroxyl generation, sealing of affected substrate, and where required removal and replacement of contaminated plasterboard and timber.

  6. STEP 06

    Verification & Sign-Off

    ATP swab testing on critical surfaces (commercial / insurer jobs), photographic evidence pack, hazardous waste consignment notes, and a written completion certificate.

Why It's Worth Doing Properly

Specific outcomes.Not vague promises.

Every benefit below is something you can measure, document or hand to an insurer - not a slogan.

Family doesn't have to do this

The single most important benefit - families are not exposed to the scene, the materials, or the disposal process.

Property restored properly

Surface cleaning leaves the contamination behind. Proper remediation removes affected substrate and decontaminates what remains - the property is genuinely safe afterwards.

Insurer-ready evidence pack

Photographic evidence, scope of works, materials removed and decontamination certification - formatted for direct submission to loss adjusters.

24/7 response

Crew mobilised within hours of scene release, day or night, across the Wirral, Liverpool and Cheshire.

Complete discretion

Unmarked vehicles, plain PPE, no signage. The street and the neighbours don't need to know what has happened.

Legally compliant disposal

All trauma waste handled under hazardous waste consignment notes - no exposure for the property owner or family.

In Detail

Methods, materialsand the situations we handle.

Trauma scene work covers a range of incident types. Here's how each is handled in practice.

Post-violent-incident cleaning

Assaults, stabbings and other violent incidents typically involve concentrated blood release in a localised area. Process focuses on containment, removal of saturated materials, and full surface decontamination - usually completed in a single day.

Suicide & self-harm scenes

Handled with the highest possible sensitivity to the family. We coordinate timing around family wishes, work with discretion regarding visible activity from the street, and provide a documented but sensitively-worded completion report.

Undiscovered death (post-mortem decomposition)

Properties undiscovered for more than 24–48 hours present decomposition products that have penetrated soft furnishings, carpet, sub-floor and plasterboard. These jobs frequently require partial strip-out and reinstatement - handled in coordination with our environmental cleaning service.

Road traffic & workplace incidents

Blood and fluid release on highways, workplaces or commercial premises - handled in coordination with the responsible authority or employer, with site-safety paperwork issued before re-entry.

Sharps & needle clearance

Discovered drug paraphernalia in stairwells, communal areas or abandoned properties - handled under our biohazard service with controlled sharps containers and hazardous waste consignment.

Working with the police, coroner & funeral director

We coordinate with police family liaison officers, the coroner's office, and funeral directors to ensure the scene is handed back in a state the family does not have to face.

FAQ

Questions,answered straight.

Can't see your answer? Call us - no obligation.

07834 371759
How quickly can you attend?

Within 2–4 hours of scene release across the Wirral, Liverpool and Cheshire, 24/7. Earlier mobilisation is usually limited only by police release, not by us.

Is this covered by household insurance?

Most household buildings policies include accidental damage cover that extends to trauma cleaning, and many include explicit biohazard cover. We provide insurer-formatted documentation as standard - and many of our jobs are paid directly by the insurer rather than the family.

How much does crime scene cleaning cost?

Pricing depends on scene extent and substrate penetration - typical contained-incident scenes are £1,200–£2,500, while extended decomposition cases involving strip-out can run £3,500–£7,500. We provide written quotation as part of the on-site assessment.

Will neighbours or the wider community know what has happened?

Not from us. Unmarked vehicles, plain PPE, no signage on site, no comment to any third party. We treat every job as if it were a member of our own family's.

Who handles the police paperwork?

The police lead the scene-release process. We attend once the scene is formally released, and we coordinate with the family liaison officer where one is appointed.

What happens to the materials removed?

Affected porous materials (carpet, underlay, plasterboard, mattresses) are removed as Category B hazardous waste under consignment notes and incinerated at an authorised hazardous waste facility.

Can you handle ongoing odour after a previous clean failed?

Yes - many of our jobs are second-pass restorations after surface-only cleaning. Persistent odour indicates substrate penetration, and proper remediation almost always requires removing and replacing the affected fabric.

Is there a confidential way to discuss this before booking?

Yes - call Shaun directly. The line is confidential, there is no obligation, and we will not call back the family or anyone else without your explicit permission.
