Licenced, ethical, and fully qualified bio cleaning experts for Devon, Cornwall, and Somerset.
At MerryWeather Bio Cleaning, we provide specialist crime scene biohazard cleaning with the highest levels of professionalism, discretion, and technical expertise. With years of experience in trauma and forensic cleaning, our team is trusted by emergency services, housing providers, and private clients across the Southwest to restore safety and dignity in the most challenging environments.
We understand that crime scenes require more than surface-level cleaning—they demand a forensic approach. Our technicians are fully trained in biohazard remediation, sharps removal, and infection control, operating in strict accordance with Cleansmart, COSHH, and Schülke standards.
Using advanced decontamination technology—including ULV foggers, ozone generators, and electrostatic sprayers—we ensure 360° disinfection, reaching even the most inaccessible areas. Our chemical solutions, including Byotrol and Envirosafe, provide long-lasting antimicrobial protection while remaining safe for reoccupation.
Whether responding to violent incidents, unattended deaths, or forensic investigations, we approach every scene with care, confidentiality, and clinical precision—restoring environments and supporting those affected with quiet professionalism.
At MerryWeather Bio Cleaning, we take training seriously. Our team is fully qualified through industry-leading providers, including Ultima Cleaning Academy, Clean as a Whistle (Growth Nation), and Sync Training Solutions.

These credentials reflect our commitment to safe, ethical, and expert-led cleaning across Devon, Cornwall, and Somerset.
