    Amanda is amazing and extremely knowledgeable in her field of expertise. She guided me through the…read moreentire process from start to finish. 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.

    I've had a long and complicated issue with mold in my bedroom/bathroom past 3 months and have been…read morethrough several mold testers and remediation companies, and Air Quality Testers is BY FAR the best one. 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.

    This company was top notch from beginning to end! I was dealing with a problem that I was unsure…read morewhat to do after a furnace maintenance person mistakenly revealed I had asbestos in and outside my unit. I had gotten other air test quotes that were much higher so I went with Air Quality. Grant was incredibly knowledgeable and talked me through the difference between TCM and PCM air test. He was honest in telling me that for a residential test, there is no need to do the more expensive test while other companies only quoted me the highest test. I paid extra for faster results as my heater is currently inoperable until I can confirm that there is no asbestos coming out of my unit. He called and confirmed my air was clear when he promised he would. I will be using them in the near future for some other tests in my home and highly recommend them for air quality testing and customer service/responsiveness! Thank you Grant and team for the assurance and quality service!

We did not receive our preliminary report as expected (took a week and a follow up text, rather than the 2-3 business days communicated) and the final report was the same (took two weeks and a follow up text after the samples were taken, rather than the one week communicated). If your needs require tighter timing or more proactive communication, maybe consider alternatives but we did get the results we paid for and are happy with the price.

    Like everyone said, I appreciated Marco's honesty. I initially found them when looking through Yelp…read moresince we were having issues with our bathroom and shed that I wanted to get remedied. After communicating through the Yelp Services option, Marco showed up the morning of during the window of time to get a free consultation. Starting in the bathroom, instead of selling us his services, he told us honestly that we could fix it ourselves by purchasing a few items since they have a minimum charge that wasn't worth it for the bathroom fix. He took the time to walk us through how to fix it and why vinegar doesn't solve the root of the problem. He pointed out things from our paint to our bathroom ventilation issues that we should address. For the shed, he truthfully told us the cost of how much it would be for him to fix it versus us doing it ourselves or hiring some people he was training instead. He wasn't afraid to recommend other people instead of himself and I truly appreciated the information he gave us. We told him we wanted it to be a gym and he even gave recommendations on how to prevent moisture problems in the future. Sometimes it's tough with people being salespeople and selling their services (and I get that they need to sell themselves for their business) but I'm grateful to meet people like Marco who I'd definitely recommend to anyone who needed mold remediation services.

    I really appreciate this honest business. Marco came by, assessed our issue and his answer really…read moreblew me away. He said if it were his house, he'd do the job himself to save money and told us exactly what to do. He could've preyed on us and told us we needed a lot of work but he was so honest. I'd totally recommend working with him and if we have any major mold issues in the future, I'd want to work with an owner like him. If he says you need mold remediation, you can likely trust that you really need it. He won't scam you if you don't.
