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!

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.

I would definitely recommend Air Quality Testers to anyone looking for professional and reliable environmental or indoor air quality testing. Great service from start to finish!

He even took the time to walk me through the entire home at the end pointing out all the major issues that would be included in the report and how the issues would need to be remediated.

She explained the types of tests needed and how she would be collecting them. She also told me if we needed more testing the samples could be used for up to four weeks. We chose Air Quality for their reviews, certification, education, experience and expertise in the field. They also have many California accreditations as well as national and the BBB. Having the BBB A+ certification means they are trustworthy. The price point for each test made it possible for more in-depth testing which is extremely valuable. If you have mold, fire damage, air quality, VOC, water damage or allergens contact Amanda to track down the source of your issue.

There was an issue with my mold test report from another company and Andrew, the owner, was kind enough to give me a 2nd opinion over yelp messages free of charge, which is why I eventually seeked them out to do a full air testing themselves. Amanda, the technician, came and did a post-remediation air quality test after the mold issue have been resolved and was extremely thorough and careful, exponentially more than the other 2 mold testers that I've used. She answered a ton of my questions with great knowledge and detail, and was extremely helpful in giving me a better understanding of mold and the situation in general. She spent A LOT of time, in contrast to other two mold testing companies that only spent 20mins max. Not only were they more professional, thorough, and answered all of my questions, they also charged me very reasonably for the amount of time and effort they put into their air testing. The last 3 months was quite an ordeal and my only regret is that I did not find this company to begin with. If I have any air quality/mold issues I'll be sure to seek them out again.
