Four Month Blood Cleanse sends certified Biohazard technicians to Atherton properties around the clock. We handle the scene so you and your family don't have to.


Four Month Blood Cleanse has served Atherton and the broader Atherton, CA area with licensed, insured Biohazard response for years. We're not a call center that dispatches whoever's cheapest β we're a dedicated crew that trains constantly and answers our own phones, 24 hours a day.
Because our team is based near Atherton, we're not waiting on a technician to drive in from out of state. We know the local roads, the local disposal facilities, and the local regulations β and that translates into a faster, smoother job for you.
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. Atherton families and businesses benefit from that consistency every time they call.
Atherton customers deserve to know exactly what training and equipment a crew is bringing into their home or business. Here's the short version.
