No one plans for a biohazard emergency. When Monrovia 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 Crime Scene Cleanup company serving Monrovia, 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 Monrovia 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.
Beyond the technical side, our Monrovia 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.
Monrovia 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 Monrovia.
From emergency scenes to scheduled commercial decontamination, our Monrovia crew covers the full range of biohazard response โ 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 Monrovia emergency team is dispatched the moment you call, day or night, weekends and holidays included.
We treat every Monrovia home like it's our own โ full sanitation, odor removal, and safe disposal so your family can return to a normal, safe space. We work around your schedule whenever possible.

Not every job fits a checklist. When Monrovia 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 Monrovia 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 Monrovia crew removes affected materials safely and eliminates odor at the source, not just on the surface.
Families in Monrovia 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 Monrovia 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 Monrovia home or business fast. We extract contaminated water, disinfect affected materials, and address any lingering odor or moisture risk.
When a property in Monrovia 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 Monrovia 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 Monrovia 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.
Using hospital-grade disinfectants and proper PPE, we remove, clean, and sanitize every affected surface.
All biohazard waste is transported and disposed of through licensed facilities, with documentation provided for your records.
Biohazard incidents happen everywhere โ homes, offices, vehicles, and public spaces. Here's how our Monrovia team adapts to each one.
The most common call we get in Monrovia 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 Monrovia to resolve incidents quickly and keep other units unaffected.
Our Monrovia 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 Monrovia vehicle jobs regularly.

We work with Monrovia 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 Monrovia customers.
Every Monrovia 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 Crime Scene Cleanup services. Here's what actually separates Four Month Blood Cleanse from the rest in Monrovia.
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 Monrovia, 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.
Our team documents every step of the job to support your insurance claim, and we bill many major carriers directly to reduce your paperwork.
If any area doesn't meet our sanitation standard, we return and correct it at no extra charge โ no questions asked.
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.
