Four Month Blood Cleanse has served Mercer Island and the broader Mercer Island, WA area with licensed, insured Crime Scene Cleanup response for years. We're not a call center that dispatches whoever's cheapest โ we're a dedicated crew that trains constantly and answers our own phones, 24 hours a day.

We hold ourselves to a higher standard than the minimum required to get licensed in WA. Continuing education, refresher certifications, and internal quality checks are part of how we operate year-round, not just something we mention in an ad. Mercer Island families and businesses benefit from that consistency every time they call.
