Four Month Blood Cleanse is a fully licensed and insured Drug Lab Cleanup company serving Walnut, 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 Walnut 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.
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. Walnut families and businesses benefit from that consistency every time they call.

When a property in Walnut 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.
