No one plans for a biohazard emergency. When Madison 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 Madison, SD 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 Madison 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.
We hold ourselves to a higher standard than the minimum required to get licensed in SD. Continuing education, refresher certifications, and internal quality checks are part of how we operate year-round, not just something we mention in an ad. Madison families and businesses benefit from that consistency every time they call.

When a property in Madison 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.
