Four Month Blood Cleanse sends certified Biohazard technicians to San Francisco 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 San Francisco 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 San Francisco crew is local โ 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. San Francisco families and businesses benefit from that consistency every time they call.
San Francisco customers deserve to know exactly what training and equipment a crew is bringing into their home or business. Here's the short version.

No two calls are identical, but most fall into a few categories. Here's a closer look at what our San Francisco 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 San Francisco crew removes affected materials safely and eliminates odor at the source, not just on the surface.
Families in San Francisco 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 San Francisco often involve biological hazards hidden under clutter โ 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 San Francisco home or business fast. We extract contaminated water, disinfect affected materials, and address any lingering odor or moisture risk.
When a property in San Francisco 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 San Francisco 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 San Francisco โ day or night โ and starts dispatching a crew immediately.
We show up quickly and quietly โ no branded trucks parked outside broadcasting what's happening.
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.
All biohazard waste is transported and disposed of through licensed facilities, with documentation provided for your records.
