They were awesome! They really exert the effort to make sure the mold inspection is done correctly. I wanted to test the air on a condo that we were purchasing (because it had a strong damp smell when you walked in). Thanks, Angstrom & Team for helping me in time.

Angstrom tested the water at each of the sinks in our daycare center for lead. They helped us get our license from the New York City Department of Health. They arrived on time and got the job done without any hassles and provided all the paperwork that I needed. Thanks again!
