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.

Jacob was professional, knowledgeable, and thorough throughout the entire process. He took the time to explain what he was testing, answered all of our questions, and provided helpful information and advice on what we could do to improve and maintain our indoor air quality.

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!

As a fellow small business owner, I cannot highly recommend Patrick and his team enough. Patrick is…read morea true Godsend and indeed an answer to prayer. We had a mold issue downstairs in a storage area in our basement. This basement area is adjacent to a renter's bedroom, so yeah, big problem! We initially tried to deal with the problem by scrubbing ourselves but my wife got sick while attempting to do so (KIDS...DON'T TRY THIS AT HOME!) Patrick to the rescue. I was able to quickly get an appointment and he was able to quickly assess the problem. His team of John and another gentleman WORKED THEIR BUTTS OFF!!!! They basically had to sand all the mold that had accumulated on the wood...I heard dual sanders going on downstairs for hours on end. THEY WORKED SOOOOOO HARD! They came by on October 1st during the heat wave when it reached 103 degrees outside. They worked from about 10 am to 4 pm to completely remediate our mold situation. When they knocked on our door at about 1 pm, they were dripping in sweat. By 430 pm or so it was done. Patrick was nice enough to leave his air scrubber for three days to completely purify the air. Patrick is an amazing businessman because he is an amazing PERSON. This guy's life is driven with PURPOSE & PASSION. Do you guys remember the Ultimate Warrior from WWE? Patrick is the ULTIMATE MOLD WARRIOR! We are thankful to God for allowing us to meet and find Patrick. His estimate was also significantly cheaper than the other 3 quotes we got and I can guarantee that the work is better just based on what I saw. The end result is our basement is free and clear of mold and I can rest easy knowing my renter's respiratory system is not compromised. THANK YOU PATRICK! I will recommend you to all my friends!

After I agreed to the work that had to be done came and did the job. So glad I called this place. I had called somewhere first and felt like I was being told lies. The estimate they gave me was 3 times what the mold warriors gave me. I felt like the mold warriors could be trusted and honest. He explained everything that was going to be done. I was very satisfied with the work. Patrick is a great guy and honest.

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.

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.

Stay away from this company…read more They secretly worked with my public adjuster behind my back and billed my insurance policy an outrageous $5,000 for an asbestos test -- all without my knowledge, authorization, or a signed contract. They even went directly to my insurance adjuster to request payment, bypassing me entirely. To make matters worse, their so-called $5,000 report is only valid for 60 days. If you don't complete the abatement work within that time, they charge you again -- even though all they do is reprint the same report with a new date. No new testing. No new work. Just another charge. When I filed a small claims case against them, they refused to accept the delivery of the court documents by not opening the door for the serving man, dodging service attempts by not answering the door. It was clear they were trying to avoid accountability. I had to find alternative ways to serve them because they simply would not cooperate. Attached is the invoice they charged against my insurance policy. I have also reported them to the California Department of Insurance and is pursuing them through small claims court. I will update this review with the outcome once the case is resolved. If you value transparency and honest business practices, please stay away from this company. Learn from my experience. If I Yelp has negative reviews ratings, I definitely will rate this company as negative! - Jason

Crew of 4 arrived on time and were efficient with set up, removal, and clean up over 2 days. The service I got was priced well compared to several others in the East Bay which was important for me. Communication with Dan was smooth and easy, and I appreciated that he walked me through the process and answered all my questions. It gave me piece of mind that things were done professionally, safely, and properly for both myself and their team's health. Note: it takes ~10 days to get the air district permit unless you pay extra for expedited service, so that the minimum wait time before abatement can start. Keep that in mind for scheduling purposes
