"Aftermath 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."

"My father passed away and was left unattended for a few days with His two dogs in the house. We called On Cal Bio on a recommendation from the local police department. John and his team were so helpful, thoughtful and professional throughout this difficult process. They even helped us load my father’s Harley into our trailer because we didn’t have a ramp. John stood with us while his team worked and let us reminisce about our father with him. The team went through everything in the house and saved everything that they could for us. During this incredibly difficult time for us, they put our minds at ease knowing that they would take care of cleaning the house completely and thoroughly. Thank you from the bottom of our hearts, john and team. "
