Four Month Blood Cleanse has served Mercer Island and the broader Mercer Island, WA area with licensed, insured Unattended Death 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.
Our Mercer Island 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 Mercer Island 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.
