📞 Call +1-844-401-0166 — Free AssessmentBiohazard cleanup isn't a commodity service. The crew you call needs specific certification, specific equipment, and specific documentation capability — or the job isn't done legally or safely.
Every technician holds current ABRA certification and OSHA 29 CFR 1910.1030 bloodborne pathogen training. Our MA contractor license is current and verifiable on any job site in Onset.
Biohazard contamination spreads with time. Our regional crew positioning in MA keeps certified technicians close to Onset — not dispatching from a distant central hub.
Every Onset job starts with a scene walkthrough and a written flat-rate estimate signed before work begins. No hourly billing, no scope creep, no invoice surprise. The estimate is the price.
Our Onset crews carry ATP luminescence meters to test surface contamination post-treatment. Numbers don't lie — if the test doesn't pass, we re-treat before leaving the property.
Our Onset team handles every category of biohazard situation under one roof, with one crew, one estimate, and one documented closeout package.
Surface disinfection alone isn't enough when biological fluids are present. Our Onset crews assess penetration depth, extract affected porous material where required, and confirm clearance with ATP luminescence results at closeout.
Decomposition odor at a Onset property isn't resolved by ventilation. Our technicians locate the contamination source, extract affected structural material, treat with EPA-registered disinfectants, and run hydroxyl generators to address volatile organic compounds at the molecular level.
Category 3 sewage water is a regulated biohazard at any Onset property. Our crews carry specific EPA List N antimicrobials rated against the pathogen profile of sewage backup events, plus IICRC S500 drying protocol documentation for insurance carriers in MA.
