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.


Four Month Blood Cleanse is a fully licensed and insured Sewage Cleanup company serving San Francisco, CA and the surrounding area. Every technician on our crew is trained, background-checked, and certified to handle biological hazards safely โ and to treat the people affected by them with dignity.
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.
We're happy to walk you through our certifications and process over the phone before you commit to anything โ call +1-844-401-0166 and ask any question you have about how we work in San Francisco.
From emergency scenes to scheduled commercial decontamination, our San Francisco crew covers the full range of biohazard response โ always with the same certified process and the same respect for your privacy.
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.
Homes in San Francisco 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.
We work with property managers, offices, warehouses, and industrial facilities across San Francisco to resolve biohazard incidents without disrupting operations any longer than necessary. Our team coordinates directly with facility staff from start to finish.
Some situations call for specialized equipment and protocol. Our San Francisco team handles the harder cases other companies turn away, including jobs that require extended containment or extra sanitation cycles.
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.
Our San Francisco crew arrives in an unmarked vehicle, dressed professionally, to protect your privacy from neighbors and passersby.
Before any work begins, we explain the process, the timeline, and the cost โ no surprises later.
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 โ homes, offices, vehicles, and public spaces. Here's how our San Francisco team adapts to each one.
The most common call we get in San Francisco โ bedrooms, bathrooms, garages, and everything in between, cleaned and sanitized with the family's privacy in mind.
We coordinate with tenants, landlords, and property managers across San Francisco to resolve incidents quickly and keep other units unaffected.
Our San Francisco commercial clients count on us to restore a space to safe, presentable condition with minimal disruption to operations.
Biohazard incidents inside a vehicle require specialized treatment of upholstery, carpeting, and hard-to-reach areas โ we handle San Francisco vehicle jobs regularly.
Larger San Francisco facilities call for a scaled-up crew and equipment set. We staff industrial jobs according to the size and complexity of the site.
We work with San Francisco property managers and municipal contacts to decontaminate shared spaces safely and get them back in service quickly.
We know the cost of Sewage Cleanup services is a real concern. Here's what to expect when it comes to pricing, insurance, and paperwork.
Every San Francisco customer gets the same level of documentation, whether the job is billed to insurance or paid directly. That consistency protects you either way.
We know you're not just comparing prices โ you're trusting someone to handle one of the hardest moments you'll deal with. Here's why San Francisco residents choose us.
You'll know the cost before we begin. We work directly with insurance when possible to reduce your out-of-pocket expense, and we explain every charge in plain language.
Because we're locally positioned near San Francisco, our average arrival time beats companies dispatching from farther away. That speed matters when biological hazards are involved.
We never discuss the details of a job outside what's necessary. Discretion is part of the service, not an upgrade you have to request.
We've worked with insurers for years and know how to document a job the way adjusters expect, which speeds up claim approval.
We don't consider a job finished until the space passes our own internal inspection standard, not just a quick visual check.
Our technicians are trained not just in decontamination, but in how to interact with people on one of their hardest days. That balance matters as much as the equipment we bring.
"They arrived within the hour and handled everything with so much care. I couldn't have gotten through that day without them, and I'll never forget how patient they were with my questions."
"Discreet, quick, and thorough. Neighbors never even noticed the crew was there, which was exactly what we needed."
"Pricing was exactly what they quoted on the phone โ no surprises on the final bill, which I really appreciated."
"They coordinated directly with my insurance adjuster which saved me hours of phone calls and a lot of stress."
"You could not tell anything had happened once they finished. The smell, the stains, everything โ gone, and they even followed up a few days later."
