Cheryl is a true professional, not only in her methodology but also in going above and beyond in offering practical suggestions to improve air quality in your home and prevent potential future issues. She was incredibly thorough, kind, and communicative. We'd rehire her and highly recommend her to anyone in the Bay Area looking for a mold inspector.

Cheryl denied that there was cross contamination despite black mold eventually being identified either by mold busters or another company. Despite what others have said, I found Cheryl to be dishonest and covering up the deceitful and dangerous disregard of health issues by my landlord. I have been sick as a result and have spent tens of thousands of dollars on healthcare. Cheryl is a bad memory and just as dishonest and disgusting as my landlords who tried to conceal the leak, deny the mold, and deny any accountability.

They were super responsive & efficient: they were able to schedule someone to come by one day after I called, and we got results the next business day. I had also asked about doing more lead testing for the rest of our home out of an abundance of precaution, since we have two little kids at home. I really appreciated that Robert gave me fair & thoughtful advice vs pushing me to test as much as possible (which would be more beneficial to TITAN). Highly recommend them!

Tyson, who did the visit, was a consummate professional. He arrived on time, ready with his equipment, and systematically performed the promised inspection and testing.

His follow up was also excellent, with the written inspection report delivered in the promised timeframe. Thankfully, I only had a minor mold issue that won't require significant remediation. Beyond Tyson, their office does a great job managing email communication, scheduling, and billing. I would definitely work with them again.

Either way they have a detailed report of the test results and are able to answer questions in a timely manner. Thank you Michelle and staff at American Air Testing!

Excellent experience from start to finish…read more We contacted Air Quality Testers during a very stressful time after an unscrupulous contractor caused a leak into a wall cavity, and we were concerned about mold. Everyone was patient in answering my many questions and scheduled our moisture and mold inspection promptly. Our inspector, Elizabeth, arrived exactly on time, immediately put us at ease, explained everything clearly, and investigated and documented the situation with exceptional attention to detail. Because we were especially worried about our child with asthma being exposed to mold, she even called us the next day with the preliminary results before the full written report was ready. The final report was clear, comprehensive, well documented, and easy to understand. After the remediation was completed, Elizabeth returned for the post-remediation sampling and was once again thoughtful, meticulous, and a pleasure to work with. Of the many contractors, investigators, and inspectors we've dealt with in the aftermath of the leak, Air Quality Testers stood out for their professionalism, responsiveness, and genuine kindness. I would highly recommend them.

His notes arrived several days later, and only covered around 1/3 of what we had talked about. I wrote to the owners to say that I thought I had overpaid for their service by a lot, and they never replied.

I have worked with Graham at least 3 times since 2020. I lived in an apartment in SF with toxic…read moremold for 2+ years, which made me extremely ill to the point where I was disabled. It took me about 2 years to fully recover, so I am extremely hesitant to rent anywhere that has the faintest musty odor. I first hired Graham in Fall 2020 when I was in a cute Berkeley duplex that had an odd odor in the living room. I hired him again when I moved into a condo rental across town that I only realized had water damage after I'd moved in, because it had been tenant occupied when I toured it and their possessions hid much of the water damage. I most recently hired Graham in 2023, after historic heavy rains caused water damage to a window in the Edwardian SF rental I was living in. I had him come by after the window leaks were repaired but before the repair person closed the wall up. Graham gave me the piece of mind that the repair was done correctly and that the apartment otherwise was in good condition with respect to his area of expertise. Graham has always been professional, extremely knowledgeable, thorough, and helpful. I have recommended him to several friends and anyone else who mentions the slightest concern about mold or water damage in their home.
