6-Step Advanced Attic Cleaning Process
Step 1: Visual Inspection
Comprehensive Onsite Overview
Our team performs a non-invasive visual inspection to document all visible conditions, safety hazards, environmental risks, property contents, and client concerns.
This overview informs an accurate, actionable service plan. It does not include any destructive testing or laboratory analysis, and any repairs or further evaluations must be handled by a separately contracted, licensed professional.
Step 2: Bio-Risk Assessment
Onsite Safety Planning
A bio-risk assessment and safety plan will be completed onsite to document and identify, assess, and mitigate the risks associated with biological hazards (biohazards) during a particular hazardous activity.
The bio-risk assessment will outline the potential biological threats, evaluate their likelihood and severity, and establish the safety procedures, PPE requirements, containment strategies, and response protocols necessary to protect workers, clients, and the environment.
Step 3: Source Removal
Remove Contaminated Insulation
Our team removes and properly disposes of contaminated insulation and materials from walls, ceilings, attics, crawl spaces, or other affected areas (e.g., mold, moisture, rodent droppings, fire/smoke residues, or other biohazards).
This service is limited to removal and disposal only; installation of new insulation or structural repairs must be performed by a separately contracted, licensed professional.
Step 4: Forensic Cleaning
6-Step Bio-Remediation Process
We perform a detailed, multi-phase cleaning sequence—Treat, Clean, Disinfect, Decontaminate, Steam, and Chemical Encapsulate—to eliminate all biohazards and restore a safe attic environment.
Step 5: ATP Verification
Pre/Post Surface Remediation Testing
We use an ATP (adenosine triphosphate) meter during both the pre- and post-remediation phases to confirm that all surfaces have been thoroughly cleaned, sanitized, and decontaminated. This device provides immediate, quantifiable results indicating the presence of organic residue, ensuring that biohazards have been effectively eliminated.
ATP testing is a critical step in validating that the remediation process meets health and safety standards before the space is deemed safe for occupancy or any further work by a separately contracted, licensed professional.
Step 6: Air Testing
Particle & Air Quality Monitoring
Pre/post remediation to use a particle meter, also known as a particle counter or air quality monitor, to measure the concentration and size of airborne particles in each environment. It detects contaminants such as dust, pollen, mold spores, smoke, and other particulate matter (PM), which are often invisible to the naked eye.
In biohazard remediation forensic cleaning, it helps ensure the air is safe, containment is effective, and HEPA filtration or negative air systems are functioning properly.
Attic Insulation Removal, Rodent Droppings Remediation in Central and Northern, CA
The insulation in your attic, no matter what kind of insulation you have, is likely to be used as bedding material for the rodents.
Rodents can shred insulation, reducing its effectiveness, and contaminate it with droppings and urine, which may also damage underlying building materials. After rodents are removed and entry points sealed, the contaminated insulation must be removed and properly disposed of.
The old attic insulation must be removed and properly disposed of, and attic insulation replacement should also happen in order to ensure that you have a well-insulated home.
911 Hazmat Cleanup, LLC specializes solely in the safe removal and disposal of contaminated insulation. Any insulation replacement, restoration, or structural repairs must be performed by a separately contracted, licensed professional.
