In Their Own Words

US Environmental Testing provides certified environmental testing services for homeowners, real estate professionals, and commercial property owners throughout the Chicago metropolitan area. Based in Glen Ellyn, Illinois, we serve all of DuPage County — including Wheaton, Naperville, Lombard, Downers Grove, Lisle, Westmont, and Elmhurst — as well as communities across Cook County, Kane County, Will County, and the broader northern Illinois region. We are a test-only firm. That means we test for environmental hazards — radon gas, asbestos-containing materials, lead paint, mold, indoor air quality problems, and water quality concerns — and we stop there.

Before You Call Northern Illinois Radon, LLC / US Environmental Testing

1. Where do you think the moisture is coming from, and who fixes it?
2. Will you set up containment and negative air, and how will you protect the rest of the home?
3. Do you also do remediation? If so, who checks your work?
4. How many air samples will you take, and will you take an outdoor control sample?
5. Is your company licensed for asbestos abatement here?

Ask for the contractor license 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.
