Four Month Blood Cleanse sends certified Biohazard technicians to Cotati properties around the clock. We handle the scene so you and your family don't have to.


We built Four Month Blood Cleanse around one idea: when a biohazard emergency happens, families and business owners in Cotati deserve a team that shows up fast, works cleanly, and communicates honestly the whole way through. Our technicians are certified in bloodborne pathogen handling, OSHA safety standards, and proper biohazard disposal.
Our Cotati crew is local β not a subcontractor pulled from three states away. That means faster arrival times, familiarity with local disposal regulations, and a team that's actually invested in this community.
We hold ourselves to a higher standard than the minimum required to get licensed in CA. Continuing education, refresher certifications, and internal quality checks are part of how we operate year-round, not just something we mention in an ad. Cotati families and businesses benefit from that consistency every time they call.
Cotati customers deserve to know exactly what training and equipment a crew is bringing into their home or business. Here's the short version.
If you want to see credentials before we arrive, just ask when you call. Transparency about our process is part of how we've built trust with Cotati customers over the years.
Every job is different, but our process isn't. Whatever brought you to this page, our Cotati technicians are trained and equipped to handle it safely, thoroughly, and discreetly.
Blood, bodily fluids, or trauma scenes can't wait, and neither do we. Our Cotati emergency team is dispatched the moment you call, day or night, weekends and holidays included.
Homes in Cotati call us for everything from hoarding cleanup to infectious disease decontamination. We restore the space fully before we leave, and we walk you through every finished area before we consider the job done.
Cotati business owners call us to get facilities back to code fast β with full documentation for insurance, health department, and OSHA compliance. We can often schedule work outside business hours to limit disruption.
Not every job fits a checklist. When Cotati families or businesses face an unusual biohazard situation, our senior technicians step in with specialized tools and training built for exactly that scenario.
No two calls are identical, but most fall into a few categories. Here's a closer look at what our Cotati team handles on a regular basis.
When a death goes unnoticed for days or longer, biological material can affect flooring, subflooring, and even structural materials. Our Cotati crew removes affected materials safely and eliminates odor at the source, not just on the surface.
Families in Cotati facing this kind of loss deserve a crew that works quickly and quietly. We coordinate with law enforcement when needed and complete cleanup once the scene has been released.
Hoarding jobs in Cotati often involve biological hazards hidden under clutter β mold, pest waste, and spoiled materials. We sort with care, separate salvageable items when asked, and sanitize the full property.
Raw sewage introduces serious pathogens into a Cotati home or business fast. We extract contaminated water, disinfect affected materials, and address any lingering odor or moisture risk.
When a property in Cotati has been exposed to an infectious illness, we perform full surface and airborne decontamination using medical-grade disinfectants to reduce risk for anyone who uses the space next.
Former drug production sites in Cotati leave behind chemical residue that ordinary cleaning can't remove. Our specialized team tests, treats, and clears the property according to CA remediation standards.
A real person answers your call in Cotati β day or night β and starts dispatching a crew immediately.
Our Cotati crew arrives in an unmarked vehicle, dressed professionally, to protect your privacy from neighbors and passersby.
We assess the scene, contain the affected area, and walk you through exactly what the job will involve before we start.
Our team follows OSHA and CA health protocols to fully decontaminate the space, not just clean the surface.
We handle chain-of-custody disposal and provide the paperwork your insurer or property manager may require.
Biohazard incidents happen everywhere β homes, offices, vehicles, and public spaces. Here's how our Cotati team adapts to each one.

We work with Cotati property managers and municipal contacts to decontaminate shared spaces safely and get them back in service quickly.
Paying for an unexpected biohazard cleanup shouldn't add to your stress. Here's how we make the financial side of the process as simple as possible for Cotati customers.
Every Cotati customer gets the same level of documentation, whether the job is billed to insurance or paid directly. That consistency protects you either way.
There's no shortage of companies that claim to offer Biohazard services. Here's what actually separates Four Month Blood Cleanse from the rest in Cotati.
We quote the job before we start β no inflated invoices, no surprise line items after the work is done. Our Cotati estimates reflect the actual scope of the job, not a guess.
Because we're locally positioned near Cotati, our average arrival time beats companies dispatching from farther away. That speed matters when biological hazards are involved.
Unmarked vehicles, plain uniforms, and a no-questions-asked approach with neighbors β your privacy matters to us on every Cotati call.
Our team documents every step of the job to support your insurance claim, and we bill many major carriers directly to reduce your paperwork.
We don't consider a job finished until the space passes our own internal inspection standard, not just a quick visual check.
We treat every Cotati customer with the same patience and respect we'd want for our own families, from the first phone call to the final walkthrough.
