Addressing environmental concerns

Our indoor air quality work is more than just collecting samples. Our goal is to understand our clients’ needs, identify any indoor environmental concerns, understand all the underlying contributing factors, and provide solutions to make buildings (and their occupants) healthier. We use a multidisciplinary approach that requires fundamental knowledge of building science, HVAC systems, toxicology, chemistry, microbiology, and more. We use the scientific method to study your building and test hypotheses to get at the root cause of your indoor environmental concerns.

"Aftermath team made a very hard event much easier. Without them, I do not know how I would have made it through this. Corry went above and beyond my expectations. She was much more than the lead and for that I am more than thankful."

Christopher R. - Tallahassee, FL

"My father passed away and was left unattended for a few days with His two dogs in the house. We called aftermath 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. "
