Biohazard Cleanup in Boston, Handled Quietly and Correctly
Biohazard cleanup, also called biohazard remediation, is the professional removal, disinfection, and verification of areas affected by blood, bodily fluids, decomposition, or other biological contamination. Done correctly, it returns a safe, fully disinfected space and a documented file your insurance carrier will accept. Done by family members or a general cleaning crew, it leaves both health risks and memories that no one should have to carry.
Studio 24 Restoration Group provides biohazard cleaning services across Boston and the South Shore with two commitments that shape everything else. First, discretion. Our crews can arrive in unmarked vehicles, work behind closed doors and covered windows, and say nothing to neighbors about why they are there. Second, compassion. Most of the people who call us are grieving, overwhelmed, or both, and we structure every step, from the first phone call to the final walkthrough, around making this easier rather than louder.
Additionally, we handle the practical side that families rarely have the energy for. We photograph and document the affected area before work begins, scope the loss in the same estimating platform insurance carriers use, and bill the carrier directly on covered claims. There is no charge for the initial assessment, and there is no upfront cost to you on covered work. You make one call, and the cleanup, the paperwork, and the claim all become our responsibility.
Because these situations rarely happen during business hours, the phone is answered by a person 24 hours a day. Call whenever you are ready, even if you only have questions. We will explain what happens next in plain language, and nothing moves forward until you say so.
A quiet word on timing. There is no countdown clock pressure here. However, biological material does become harder to remediate and affects more materials the longer it remains, so most families choose to have us assess within a day. The assessment is free and commits you to nothing.

The Situations Our Biohazard Cleaning Services Cover
Every situation on this page deserves its own careful explanation, and each has one. Here, briefly and respectfully, is the scope of what our crews handle across Boston and the South Shore.
The most common call we receive is after an unattended death, when someone has passed away and was not found for a period of time. These losses affect flooring, subflooring, and sometimes the spaces below, and they need professional remediation rather than cleaning in any ordinary sense. Our unattended death cleanup crews remediate the affected area completely and treat the home, and everything in it, with the respect a family’s home deserves.
We also respond to trauma and accident scenes, including serious falls, workplace injuries, and medical emergencies in the home. Anywhere blood or bodily fluids are present, remediation follows the same careful protocols, which we cover in detail on our blood and bodily fluid cleanup page. After a crime, families searching for crime scene cleaners should know one timing detail: work cannot begin until investigators formally release the scene, and our crime scene cleanup team coordinates that timing with you so nothing is disturbed early and nothing waits longer than it must.
Hoarding environments are a different kind of call, and often a harder one to make. The American Psychiatric Association estimates that hoarding disorder affects around 2 to 6 percent of people, which means these situations are far more common in Boston’s long-held family homes than most people realize. Our hoarding cleanup in Boston is done with the occupant and the family, never to them, and belongings are sorted rather than swept away.
Finally, we remediate contamination that spreads through a home rather than staying in one room. Sewage-contact contamination in living spaces is handled under the same Category 3 protocols our sewage backup cleanup crews use, and infectious disease concerns, from a household illness to a shared building, are addressed by our disinfection and sanitization service using hospital-grade products applied room by room.
Who Pays for Biohazard Remediation in Massachusetts?
Money should be the last thing a family has to think about in these circumstances, so we will answer the question directly: in many situations, an insurance policy pays for biohazard remediation, and you pay only your deductible. The table below reflects what we typically see on Massachusetts claims. It is practical guidance from a restoration contractor, not legal or insurance advice, and your policy language controls.
| Situation | Who typically pays | What to know |
|---|---|---|
| Unattended death in an owner-occupied home | Homeowners policy, in many cases | Remediation of the structure is often covered. We document everything and bill the carrier directly. |
| Death or trauma in a rental unit | Landlord’s property policy for the structure | A tenant’s belongings usually fall under the renter’s policy. We help both sides document their claim. |
| Crime in the home | Homeowners policy, plus possible state help | Massachusetts runs a victim compensation program that can reimburse eligible crime-related cleanup expenses. Cleanup begins only after police release the scene. |
| Hoarding environment | Usually the family or estate | Hoarding alone is rarely a covered peril. However, related covered damage underneath, such as a long water leak, sometimes brings part of the work into a claim. |
| Sewage contamination in living space | Water or sewer backup endorsement | Coverage depends on whether the policy carries a backup endorsement. We verify before work begins. |
Whatever the situation, the process on our side stays the same. We assess for free, tell you honestly whether we believe the loss is coverable, and put the scope in writing before anything starts. Owner Ansy Chevalier scopes these losses personally and meets adjusters at the property when a carrier is involved, and our insurance claims page explains the whole process from first call to final payment. If a loss is not coverable, you will know that before you owe anyone anything.

How Does Our Trauma Cleanup Process Work, Step by Step?
Families tell us that knowing exactly what will happen, and in what order, makes the day easier. Therefore, we follow the same measured sequence on every biohazard loss, whether it is a single room or a whole floor. Nothing is rushed, and nothing is improvised.
Two parts of this process matter most. Containment means the affected area is isolated before work begins, so contamination does not spread and so you never have to see the work in progress. Verification means we do not declare a surface clean because it looks clean. Instead, we test it with ATP meters, the same luminescence technology hospitals use to audit sanitation, and we remediate again if a reading misses the threshold. When we hand a room back, that judgment rests on measured data rather than on anyone’s opinion.
Throughout, one crew lead is your single point of contact. You will never repeat your story to a stranger twice.
- AssessmentA quiet walkthrough, a written scope, and clear answers. Free, and nothing proceeds until you approve.
- ContainmentThe affected area is isolated with barriers so contamination stays put and the rest of the home stays usable.
- RemovalAffected materials are removed under bloodborne pathogen protocols and packaged for transport by licensed medical waste carriers.
- DisinfectionEvery affected surface is treated with hospital-grade, EPA-registered disinfectants, applied to full contact time.
- VerificationATP surface testing confirms cleanliness against measurable thresholds, not appearances.
- Compassionate handoffA final walkthrough at your pace, complete documentation for the insurance claim, and the room returned to you.

Why Should Family Members Never Clean the Scene Themselves?
This is the most important thing on this page, so we will say it plainly. Please do not clean the area yourself, and do not let a relative or a well-meaning neighbor do it either. There are two reasons, and both matter.
The first reason is health. Blood and bodily fluids can carry bloodborne pathogens, including hepatitis B, hepatitis C, and HIV, and some of these remain viable on surfaces for days. That is why federal law regulates this work under the OSHA bloodborne pathogen standard, and why professionals wear full personal protective equipment, follow strict decontamination sequences, and send waste through licensed carriers. Household cleaners and determination are not protection, and contamination often extends into materials, such as subflooring, that surface cleaning cannot reach at all.
The second reason is the one families tell us about years later. What is seen while cleaning cannot be unseen, and grief is heavy enough without adding that weight to it. As owner Ansy Chevalier puts it, “Our job is to make sure no family carries the memory of cleaning up after the worst day of their lives. We take that off their hands completely, and we consider it the most important work we do.”
So let this be the one task you hand to strangers. Kind, trained, quiet strangers, who will treat your home like their own and leave it safe.
The Myth
“The police or the coroner will clean the scene before they leave.”
What Actually Happens
They do not. Once investigators and the medical examiner finish their work, responsibility for cleanup passes to the property owner. Massachusetts families are often surprised by this, which is why our crews respond as soon as a scene is released, day or night.
If you are standing in the home now: close the door to the affected room, keep people and pets out, and call (781) 390-9855. You do not need to look at it again. We will handle everything from here.
The Standards Behind Our Biohazard Cleanup Company
Trust in this work has to rest on something firmer than promises, so here is exactly what governs ours. Our technicians are trained to the OSHA bloodborne pathogen standard, 29 CFR 1910.1030, the federal rule that dictates exposure control, protective equipment, decontamination, and waste handling wherever blood or other potentially infectious materials are present. OSHA estimates that 5.6 million workers in health care and related occupations face occupational exposure to bloodborne pathogens, and the procedures written to protect them are the same procedures that protect your home.
Layered on top of that is the IICRC S540 standard for trauma and crime scene cleanup, the industry’s consensus document for how biological contamination is assessed, contained, removed, and verified in homes and businesses. Studio 24 is an IICRC certified firm, and our biohazard remediation follows S540 the way our water crews follow S500: as a written procedure, not a suggestion. Disinfection itself is done with hospital-grade, EPA-registered disinfectants, chosen for proven effectiveness against the pathogens of concern and applied to the full contact time on the label, because a disinfectant wiped off early is chemistry wasted.
Verification and disposal close the loop. ATP meters give us numeric surface readings so that clean is a measurement, and everything removed from the property travels as regulated medical waste through licensed carriers in accordance with Massachusetts Department of Public Health requirements, with a documented chain of custody. Consequently, when the work is finished you receive more than a clean room. You receive a file showing what was found, what was done, what the readings were, and where every removed item went, which is precisely the documentation an insurance carrier, a landlord, or a future buyer may one day ask to see. Lingering odor, when present, is treated as its own remediation step through our odor neutralization service rather than masked with fragrance.
Protective equipment and containment staged before any work begins.
Discreet Cleanup Nearby, in the Homes Boston Actually Has
People searching for discreet cleanup nearby usually want to know one practical thing: does this company understand homes like mine, and neighborhoods like mine. Here, the honest answer is yes. A large share of our biohazard calls come from Boston’s triple-deckers, where a landlord or a downstairs neighbor is often the one who discovers an unattended death, and where shared walls, shared entries, and stacked units mean both the remediation and the discretion have to be handled carefully. We know how to work in those buildings without turning a private loss into a building-wide event.
The South Shore brings its own patterns. Capes and colonials in towns like Weymouth, Braintree, and Randolph are frequently long-held family homes, and those are the houses where hoarding conditions build gradually over decades and where the adult children calling us are navigating a parent’s dignity along with the cleanup itself. In every case, the crew that arrives is local, the owner’s name is on the work, and the neighbors learn nothing from us. Quiet arrivals, plain clothing over protective gear where practical, and unmarked vehicles on request are standard offerings, not special favors.
Where Our Biohazard Cleanup Crews Respond
Our biohazard cleanup crews cover Boston’s neighborhoods and the full South Shore, 24 hours a day. Because discretion matters as much as distance on these calls, we dispatch from within the area rather than routing you to a regional call center, and the person who answers the phone can tell you honestly how soon a crew arrives at your address.
Answers for a Hard Day
Questions Boston Families Ask Us, Answered Gently
How fast can you come?
Usually within a few hours anywhere in Boston and the South Shore, and we answer the phone 24 hours a day. That said, this timeline is yours to set. If you need us tonight, we come tonight. If you need a day before anyone enters the home, we will schedule around you.
Is biohazard cleanup covered by insurance?
Often, yes. Many Massachusetts homeowners and property policies cover biohazard remediation after a death, trauma, or crime in the home, and Massachusetts also runs a victim compensation program for eligible crime-related expenses. We verify your coverage during the free assessment, bill the carrier directly, and tell you plainly if we believe a loss is not coverable.
Do you work discreetly?
Yes, completely. Unmarked vehicles are available on request, crews cover windows and work behind closed doors, and we never discuss the nature of the work with neighbors, tenants, or anyone else. Discretion is a standing instruction on every biohazard job we run, not something you have to ask for twice.
Is the area safe to enter after you finish?
Yes. We do not return a space until disinfection is verified with ATP surface testing against measurable thresholds, and all affected materials have been removed and transported as regulated medical waste. You also receive the documentation showing exactly what was done and what the final readings were, so the answer rests on data rather than reassurance.
What happens to my loved one's belongings?
They are treated as carefully as the home itself. Items that can be safely cleaned and disinfected are restored and returned to you. Items that cannot be saved are photographed and documented for the insurance claim first, and nothing sentimental is discarded without your explicit consent. If you are not ready to decide about certain items, we set them aside until you are.
Discretion holds everywhere we work, from Quincy three-deckers to quiet single-family streets in Stoughton and Canton.
One last note for anyone reading this before they need it. If your situation involves sewage rather than trauma, start with our sewage backup cleanup page linked above, where the Category 3 water protocols are explained in full. For everything else on this page, the first step is the same: one phone call, answered by a person, followed by a free and unhurried assessment. Last updated August 2026.
