Decomposition

Decomposition & Odor Control

Biological decomposition at a Cohasset property generates volatile biogenic amines that penetrate HVAC systems and subfloor materials. We neutralize biogas compounds using hydroxyl generator technology — not masking agents — and verify odor elimination before closeout.

Category 3 Sewage

Category 3 Sewage Biohazard Response

Sewage backups at Cohasset properties carry hepatitis A, norovirus, E. coli, and salmonella — pathogens that survive on surfaces long after visible water is removed. We apply EPA-registered antimicrobials rated for the Category 3 pathogen spectrum and document drying per IICRC S500 standards.

Chemical

Chemical & Drug Lab Decontamination

Meth lab residue at a Cohasset property saturates drywall, HVAC ductwork, and framing — invisible but regulated under MA law. We coordinate IH sampling, perform solvent-specific decontamination, and produce state health authority clearance documentation required for legal re-occupancy.

Crime Scene

Post-Release Crime Scene Response

Our Cohasset crime scene crews understand chain-of-custody awareness, scene-release protocol in MA, and the documentation insurance adjusters require to close claims without follow-up requests.

Hoarding

Biohazard-Level Hoarding Cleanup

Hoarding biohazard remediation in Cohasset follows a phased approach: hazard assessment, PPE selection, pest coordination, material segregation, systematic sanitation, and odor neutralization — documented at every stage.

Marcus T.Cohasset, MA
★★★★★

"Three companies on my list before I called Crime Scene Cleaner Online. The difference was that they actually explained what they were going to do before doing it — UV mapping, EPA chemistry selection, ATP verification at closeout. That level of transparency is how you know you're calling the right team."

Sandra L.Property Manager, Cohasset
★★★★★

"The decomposition odor in my rental unit had defeated two previous cleaning companies. Crime Scene Cleaner Online found the source in the subfloor cavity no one else had checked, ran hydroxyl generators after treatment, and the ATP results confirmed complete clearance. The unit re-rented without any odor disclosure issue."
