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


We built Four Month Blood Cleanse around one idea: when a biohazard emergency happens, families and business owners in San Lorenzo deserve a team that shows up fast, works cleanly, and communicates honestly the whole way through. Our technicians are certified in bloodborne pathogen handling, OSHA safety standards, and proper biohazard disposal.
Our San Lorenzo 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 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. San Lorenzo families and businesses benefit from that consistency every time they call.
