No one plans for a biohazard emergency. When Calistoga 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 Biohazard company serving Calistoga, 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.
Because our team is based near Calistoga, 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 Calistoga 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.
Calistoga 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 Calistoga customers over the years.
From emergency scenes to scheduled commercial decontamination, our Calistoga 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 Calistoga emergency team is dispatched the moment you call, day or night, weekends and holidays included.
We treat every Calistoga 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.
We work with property managers, offices, warehouses, and industrial facilities across Calistoga 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 Calistoga 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 Calistoga 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 Calistoga crew removes affected materials safely and eliminates odor at the source, not just on the surface.
Families in Calistoga 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 Calistoga 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 Calistoga home or business fast. We extract contaminated water, disinfect affected materials, and address any lingering odor or moisture risk.
When a property in Calistoga 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 Calistoga 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 โ no branded trucks parked outside broadcasting what's happening.
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.
All biohazard waste is transported and disposed of through licensed facilities, with documentation provided for your records.
Four Month Blood Cleanse isn't limited to one type of property. Whatever the setting, our Calistoga crew brings the same certified process and equipment.

Biohazard incidents inside a vehicle require specialized treatment of upholstery, carpeting, and hard-to-reach areas โ we handle Calistoga vehicle jobs regularly.

We work with Calistoga 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 Calistoga customers.
Every Calistoga 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 Biohazard services. Here's what actually separates Four Month Blood Cleanse from the rest in Calistoga.
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 Calistoga, 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 treat every Calistoga customer with the same patience and respect we'd want for our own families, from the first phone call to the final walkthrough.
