This was a topic I could have lived forever without having much knowledge given it was my home. The initial phone call provided so much comfort. The level of expertise is stellar. Reviewing their licensing and certifications alone speaks for itself. They don't just run an air test and send it to a lab, they do multiple types of tests, consider all circumstances and evaluate the whole home. Highly recommend these individuals for their honesty, timeliness and expertise in their field. The fact they are from my home state is a bonus. :)
