No one plans for a biohazard emergency. When San Francisco residents and businesses need help, Four Month Blood Cleanse responds fast, works quietly, and treats every property โ and every person โ with respect.


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.
Because our team is based near San Francisco, we're not waiting on a technician to drive in from out of state. We know the local roads, the local disposal facilities, and the local regulations โ and that translates into a faster, smoother job for you.
Beyond the technical side, our San Francisco team understands that a biohazard call almost always comes during a stressful, sometimes traumatic moment. That's why every technician goes through communication training in addition to safety certification โ so you get a crew that's skilled with equipment and calm with people.
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.
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 San Francisco customers over the years.
Every job is different, but our process isn't. Whatever brought you to this page, our San Francisco technicians are trained and equipped to handle it safely, thoroughly, and discreetly.
When you call our emergency line in San Francisco, we mobilize a crew immediately โ no waiting until morning, no answering machines. A technician stays on the phone with you until help arrives if you need it.

San Francisco business owners call us to get facilities back to code fast โ 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 San Francisco 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 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.

Using hospital-grade disinfectants and proper PPE, we remove, clean, and sanitize every affected surface.
