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


We built Four Month Blood Cleanse around one idea: when a biohazard emergency happens, families and business owners in Berkeley 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 Berkeley, 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 β and that translates into a faster, smoother job for you.
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. Berkeley families and businesses benefit from that consistency every time they call.
Berkeley 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 Berkeley customers over the years.
From emergency scenes to scheduled commercial decontamination, our Berkeley crew covers the full range of biohazard response β always with the same certified process and the same respect for your privacy.
Blood, bodily fluids, or trauma scenes can't wait, and neither do we. Our Berkeley emergency team is dispatched the moment you call, day or night, weekends and holidays included.
We treat every Berkeley home like it's our own β full sanitation, odor removal, and safe disposal so your family can return to a normal, safe space. We work around your schedule whenever possible.
We work with property managers, offices, warehouses, and industrial facilities across Berkeley to resolve biohazard incidents without disrupting operations any longer than necessary. Our team coordinates directly with facility staff from start to finish.
Not every job fits a checklist. When Berkeley 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 Berkeley 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 Berkeley crew removes affected materials safely and eliminates odor at the source, not just on the surface.
Families in Berkeley 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 Berkeley 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 Berkeley home or business fast. We extract contaminated water, disinfect affected materials, and address any lingering odor or moisture risk.
When a property in Berkeley 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 Berkeley leave behind chemical residue that ordinary cleaning can't remove. Our specialized team tests, treats, and clears the property according to CA remediation standards.
No hold music, no call centers overseas. Your call is answered locally and a technician is assigned right away.
We show up quickly and quietly β 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.
We handle chain-of-custody disposal and provide the paperwork your insurer or property manager may require.
Four Month Blood Cleanse isn't limited to one type of property. Whatever the setting, our Berkeley crew brings the same certified process and equipment.
The most common call we get in Berkeley β 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 Berkeley to resolve incidents quickly and keep other units unaffected.
Our Berkeley 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 β we handle Berkeley vehicle jobs regularly.
Larger Berkeley 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 Berkeley 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 Berkeley customers.
Every Berkeley 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 β you're trusting someone to handle one of the hardest moments you'll deal with. Here's why Berkeley residents choose us.
We quote the job before we start β no inflated invoices, no surprise line items after the work is done. Our Berkeley estimates reflect the actual scope of the job, not a guess.
Because we're locally positioned near Berkeley, 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.
If any area doesn't meet our sanitation standard, we return and correct it at no extra charge β no questions asked.
We treat every Berkeley customer with the same patience and respect we'd want for our own families, from the first phone call to the final walkthrough.
"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."
"The technician explained the whole process before touching anything. That transparency meant a lot to my family during a very hard week."
"I called three companies and Four Month Blood Cleanse was the only one that answered at 2am. That alone earned my trust, and the work itself was just as impressive."
"Fast, professional, and genuinely kind. The crew never made me feel rushed even though I know they had other calls that day."
"They showed up in an unmarked van exactly as promised. I appreciated not having neighbors ask questions about what was going on."
