They were awesome! They really exert an effort to make sure the mold inspection was done correctly. I wanted to test the air in a condo that we were purchasing because it had a strong damp smell when you walked into the condo. Apparently, the undersides of the floorboards in the entrance foyer were moldy from rain seeping through the door frame.

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!
