(Fort Smith, AR) – Cleaning a home following a murder or suicide is a difficult job for anyone. If the victims were family members, then the emotional impact of the task may be too great a burden for most to bear. Furthermore, if biological materials are not properly cleaned up, they can damage not only the home’s value, but the health of future occupants as well. For these reasons, it can be beneficial to retain a professional bioremediation company to clean the death scene.

Following a tragic situation in Fort Smith, Arkansas, one family opted to have On Call Bio remediate their residence. One of the decedents passed away in the dining room, where biological fluids had affected the tiled floors and the carpet in the connected living room. Technicians removed the saturated carpet and several tiles in the dining area to verify that the contamination had not spread to the subfloor beneath.

An office was also heavily affected, which required the walls and floors to be cleaned and sanitized. There was also minor damage to an adjoining bathroom wall and a door leading from the office into the bath. Technicians removed the material around the holes on either side and through the wall, to be certain all traces of biological matter were fully eliminated. Once the remediation was complete, an On Call Bio supervisor remained on site to better explain to the contractor what repairs would be necessary to fully restore the home to a habitable state.


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.”
