In Their Own Words

Whether you’re getting ready to sell, inspecting a new house, or want to confirm that your home /office is safe, we’re here to provide peace of mind. The lab was co-founded in 2011 by Dr. Joseph Leija, a board-certified allergist, and Darryl Morris, an Aerobiologist, home safety advocate, speaker, and author. Our team of aerobiologists and environmental hygienists has completed more than 15,000 safety inspections to test for mold, asbestos, and other indoor air quality hazards. We are researchers, scientists, and safety consultants – not salesmen. As a ‘test-only’ mold inspection company, we will never refer you to a remediation company or sell your information. Instead, you deserve honest answers with a thorough, transparent explanation.

Before You Call Midwest Aerobiology Labs (Mold & Asbestos Inspectors)

1. Do you take moisture readings every day and will you give me the drying log?
2. Are your technicians certified in water damage restoration?
3. Where do you think the moisture is coming from, and who fixes it?
4. Will you set up containment and negative air, and how will you protect the rest of the home?
5. Do you also do remediation? If so, who checks your work?

Ask for the contractor registration your city or village requires, since Illinois has no statewide general contractor license, and check it with the local building department. Also ask for proof of insurance and industry certification for the technicians.
