I called Rarefied Air Environmental to perform some mold testing for me at one of my San Diego properties. I spoke with Yumi at the office and scheduled an appointment for the same day. Bruce was able to get someone out the same day and get me results by the following day.

You never know when you’re going to need a service like Rarefied Air Environmental offers. As a brand new home owner I wanted to make sure that my home was safe to use for business purposes. Im glad I made that call, I spoke with Bruce and he assured me they have been in the field for several decades and know the ins and outs. I’m glad since I wasn’t sure what I was testing.
