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


Four Month Blood Cleanse is a fully licensed and insured Blood Cleanup company serving Hayward, CA and the surrounding area. Every technician on our crew is trained, background-checked, and certified to handle biological hazards safely β and to treat the people affected by them with dignity.
Our Hayward crew is local β 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 Hayward 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 β so you get a crew that's skilled with equipment and calm with people.
Biohazard cleanup isn't just about scrubbing a surface β it's a regulated field with real health and safety requirements. Here's what stands behind every job we do in Hayward.

No two calls are identical, but most fall into a few categories. Here's a closer look at what our Hayward 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 Hayward crew removes affected materials safely and eliminates odor at the source, not just on the surface.
Families in Hayward 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 Hayward 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 Hayward home or business fast. We extract contaminated water, disinfect affected materials, and address any lingering odor or moisture risk.
When a property in Hayward 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 Hayward leave behind chemical residue that ordinary cleaning can't remove. Our specialized team tests, treats, and clears the property according to CA remediation standards.

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.
All biohazard waste is transported and disposed of through licensed facilities, with documentation provided for your records.
