No one plans for a biohazard emergency. When Larkspur 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 Larkspur 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 Larkspur 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.
Beyond the technical side, our Larkspur 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.
Larkspur 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 Larkspur customers over the years.

Raw sewage introduces serious pathogens into a Larkspur home or business fast. We extract contaminated water, disinfect affected materials, and address any lingering odor or moisture risk.
When a property in Larkspur 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.
