Decomposition Cleanup Checklist: What Property Owners Need to Do

Immediate Steps (First Hour)

Your first priority is protecting yourself and everyone else from exposure to biological hazards at the scene. This checklist is one part of the broader process of decomposition cleanup, and that page gives the full overview.

1. Do not enter the scene. Decomposition produces bloodborne pathogens, airborne bacteria, and toxic gases. Even brief exposure without proper personal protective equipment carries serious health risk. Stay out until law enforcement clears the area.
2. Call 911. An unattended death must be reported to law enforcement before any other action. Do not move, touch, or disturb the body or surrounding materials.
3. Keep others away. Prevent family members, tenants, or bystanders from entering the room or unit. Post a physical barrier at the entrance if needed.
4. Turn off HVAC at the thermostat, not at the unit. Heating and cooling systems can spread aerosolized biological particles through ductwork to other rooms or units. Switching the thermostat to OFF stops airflow without requiring you to enter the scene.
5. Open exterior windows from outside the room if safely possible. This reduces odor buildup in adjacent spaces. Do not lean into the room to do this.
6. Note the time and date. You will need this for law enforcement, your insurance claim, and the cleanup company's assessment.
7. Photograph the exterior of the space only—door, hallway, any visible secondary damage to adjacent areas. Do not photograph inside the scene until law enforcement permits it.

Within the First 24 Hours

Once law enforcement has released the scene, your documentation and planning phase begins. Before working through this checklist, the property owner or responsible party must confirm who is legally and financially obligated to arrange cleanup, because the answer affects insurance documentation, cost recovery, and legal compliance. The page on who cleans up after unattended death lays out the professional cleaner's role, family versus professional responsibility, and the legal requirements. It also clarifies the distinction between coroner responsibilities and property owner obligations.

1. Get written scene release from law enforcement. Ask the responding officer for written confirmation that the scene has been released to you. Some insurance carriers require this document.
2. Photograph affected areas before anything is moved or cleaned. Capture walls, flooring, furniture, and any secondary areas with visible staining or odor damage. These photos are your pre-remediation baseline for insurance purposes.
3. Do not remove, discard, or clean anything yourself. Items that appear unaffected may carry biological contamination invisible to the naked eye. Premature removal can void insurance coverage and increase health risk.
4. Contact your property insurance carrier. Report the loss and ask specifically about biohazard remediation coverage. Request a claim number and the name of your adjuster in writing.
5. Obtain at least one written estimate from a licensed biohazard remediation company. A written estimate, not a verbal one, is what insurers accept. The estimate should itemize labor, materials, disposal, and any structural assessment.
6. Secure the property. Change or rekey locks if the death involved an unauthorized occupant or if the scene has been accessible to others.
7. Notify your property manager or HOA if applicable, as shared ventilation systems may require inspection.

During Professional Cleanup

A trained biohazard remediation crew handles the scene itself. Your role during this phase is coordination and documentation, not participation. As part of that oversight, confirm that the cleanup company is handling biological waste according to EPA and state biohazard disposal regulations, because improper disposal creates liability for the property owner, not just the contractor. Biohazard waste follows set rules and a defined process, which are explained in biohazard waste disposal regulations. That page details manifest requirements, licensed transporter obligations, and what documentation the property owner should retain.

1. Provide scene access and a contact number. Be reachable but do not hover inside the work area. Technicians wear full PPE; you should not be in the space without equivalent protection.
2. Ask for a written scope of work before work begins. The scope should list every area to be treated, materials to be removed, and the decontamination standard the crew is working to.
3. Confirm how waste will be disposed. Biohazardous waste must be transported and disposed of in compliance with applicable state and federal regulations. Ask for a waste manifest or disposal certificate—your insurer or future tenants may request it.
4. Ask whether air quality testing is included or recommended. In cases involving prolonged decomposition, aerosolized particles can penetrate porous building materials. Air quality testing after remediation gives you documented proof the space is safe.
5. Do not repaint, recarpet, or restore until the remediation crew confirms biological clearance. Sealing contaminated surfaces under new materials traps odor and health hazards and voids any clearance certificate.
6. Keep all receipts, invoices, and written communications. Organize these by date in a physical or digital folder labeled with the claim number.

After Cleanup Is Complete

Clearance from the remediation company is not the last step—you still have property, legal, and financial loose ends to close. The checklist does not end when the biohazard team leaves, because the property often requires structural assessment, material replacement, and a formal clearance certification before it can be legally reoccupied. Structural repair, material replacement, and clearance certification are covered in restoration steps after decomposition cleanup. Blue Hawk Crime Scene Cleanup coordinates both cleanup and restoration referral, so call (984) 230-1489 to discuss the full scope of work.

1. Request a written clearance certificate. This document states that the affected area has been remediated to an acceptable biological standard. Keep the original; give copies to your insurer and retain one for future property transactions.
2. Inspect HVAC filters and ductwork. Replace filters in any system that was running during or after the event. Have ducts inspected if airflow connected the scene to other units or rooms.
3. Assess structural materials for secondary damage. Prolonged decomposition fluids can penetrate subfloor, insulation, and wall cavities beneath what is visually apparent. A structural assessment may be required before reoccupancy.
4. Review disclosure requirements for your state. Many states require sellers and landlords to disclose that a death occurred on the property within a defined period. Consult a licensed real estate attorney in your state before re-listing or re-leasing.
5. Submit your complete insurance claim package. Include: written scene release, pre-remediation photographs, written estimate, all invoices, clearance certificate, and any structural assessment reports.
6. Document odor status at 30 days and 60 days post-cleanup. Some odor returns seasonally as temperatures rise. A dated written note of "no odor detected" at each interval strengthens your record if a dispute arises later.

Documentation for Your Insurance Claim

Insurance coverage for biohazard remediation varies by policy, but every claim depends on the same core documents. One of the first things a property owner should do is contact their insurance carrier, because many homeowners policies include provisions for biohazard remediation that can significantly offset out-of-pocket costs. Insurance coverage for unattended death cleanup, including homeowner policy coverage, renter policy provisions, and the claim process, is broken down in homeowners insurance coverage for decomposition cleanup. That page details what documentation the insurer will require and how to initiate the claim before work begins.

• Pre-remediation photographs — taken before any cleaning, removal, or alteration. Date-stamp these in your phone's camera settings before shooting.
• Written law enforcement scene release — confirms the space was legally released to you before work began.
• Itemized written estimate — from the remediation company, broken down by task, not a single lump sum. Lump-sum estimates are frequently challenged by adjusters.
• All paid invoices — matching the line items on the estimate. Flag any changes from estimate to invoice and ask for a written change order explaining the difference.
• Waste disposal documentation — manifest or certificate confirming lawful disposal of biohazardous material.
• Post-remediation clearance certificate — written confirmation of biological clearance.
• Structural assessment report — if subfloor, drywall, or insulation was affected.
• Your own dated notes — a simple log noting who you spoke with, when, and what was decided. This log is admissible evidence in a coverage dispute.
