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.

"Lacey and her team are amazing. We never experienced anything like this they walked us through process explained everything upfront even cost and went above and beyond. They were professional, compassionate and informative from minute they showed up even on a holiday. Sorry to say this hope I never need their services again but if we did Aftermath will be our 1st call. Thank you so much."

"The Pasadena Aftermath team did an outstanding job. Not only are they a remarkable team, they are also exceptional individuals. Over the course of the week that they were here, we got to know and trust them. They handled this unthinkable situation with grace, compassion, and the utmost respect for the victims. Words will never be able to truly capture the appreciation we have for them. When our world felt like it was hit with a tsunami, your team threw us a life preserver and told us that we will be okay again.The world needs more “Kevins”, “Jamies”, and “Hassens”, who will help lift the burden off of strangers who are facing their darkest days."

Ashlyn B. - September 5, 2022

"Sterling and Aurelia did much more than clean the scene. They were patient, kind, and very compassionate. They took good care of the property as if it was there own. Sterling and Aurelia communicated with us every step of the way. Their presence alone did much to contribute to the healing process. On top of all that, they did a fantastic job cleaning the house. To be honest, we hated to see them leave. Our family thank them both to the highest degree!!"
