Our Houston crime scene cleanup office is strategically located to serve cities and neighborhoods throughout South Texas, from Beaumont and Port Arthur, to San Antonio and Austin, and down to Corpus Christi and Brownsville.

On Call Bio Services understands that not only are trauma cleaning situations unexpected and upsetting, but they can also be dangerous and difficult to clean. Blood or other hazardous materials may contain viruses, bacteria and mold, which are not visible to the naked eye.

In a hoarding situation, for example, just removing the excess clutter will not remediate any underlying hazards such as pathogens from animal urine. For hoarding cleanups and other bioremediation situations, restoring a safe home or work place may require professional disinfection.

Fort Worth, TX – An unexpected death is a tragedy, but when an individual takes their own life, the grief associated with the event is often intensified. In addition to sensitively working with relatives, property managers must also consider the serious safety and health hazards caused by a death in one of their units. In this case, a man committed suicide in the living room of his apartment in Fort Worth, Texas. The person who ran the apartment complex spoke to the previous property manager about the situation, and the former manager recommended On Call Bio. On Call Bio came in to cleanse and sanitize the living room where the death occurred. By calling in professional death scene cleaners, the manager helped to protect the health and safety of the apartment’s future occupants.


If you or someone you know was a victim of a crime, On Call Bio has collected some resources to help guide you through this process.

“On Call Bio was very professional and was able to accommodate the urgency in the situation. They explained the services and was able to relieve my worries as they dealt with the insurance company. Other companies were unable to take the job or handle the job with efficiency to get the ball moving. Since I was needing the job done in a small window of time.”
