Four Month Blood Cleanse is a fully licensed and insured Biohazard Cleanup company serving San Diego, 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.

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.
