Choosing Fast Mold Testing was one of the best decisions I've made. From start to finish, the entire process was handled with professionalism, care, and true customer service. I am so happy I chose this company! From my very first phone call with Alex to my in-person inspection with Michael, the entire experience was flawless. Alex is incredibly kind and very helpful for taking the time to answer all my questions before and after inspection. He explained everything clearly and made me feel confident that I was in good hands. Michael arrived for the inspection, he was on time, respectful, and very professional. He took his time examining every area of concern thoroughly and explained what he was seeing as he went. He was incredibly personable and easy to talk to and patient -- never rushed, never dismissive. I also like that he showed up in an Uber instead of a company marked vehicle! The price was very fair and well worth it for the service and report. The report was detailed, very thorough, and incredibly well organized. It included infrared readings and regular photos, humidity, temperture, and moisture readings. It was helpful with tips on what to do. I finally have a peace of mind with results and it was exactly what i needed. You can tell they take pride in their work and truly care about helping their customers. Both Alex and Michael went above and beyond to provide excellent service, and I'm beyond grateful for their help. I would highly, highly recommend this company to anyone who needs honest, professional, and caring mold inspection services. Thank you for all you do. read more

Customer service superb and extremely prompt inspection scheduled and results emailed the next day. I'm very satisfied with this business and the services provided to me & my newborn baby. I discovered mold in an apartment I had been living in for two months. I reached out to this business and they scheduled an inspection that same evening for me and came out the next day by 8 AM sharp. The inspection was completed very thoroughly. You can tell Michael Nguyen the inspector was not rushing and took his time. He actually went outside and inspected the windows and the way they were installed and WHY the mold was there and what was causing it . The report was sent to me via email by the next day by 8 PM. It was extremely detailed and he actually took the time in about a 20 minute phone call to explain what it meant, and what I should do going forward whether it's moving out or cleaning the furniture. He was extremely professional, but also very personable and answered every single one of my questions. I would very much recommend this to anybody worried about mold in their house or apartment. If there were anything more than five stars, I would give it. I did not get compensated for this review. just wanted to share how amazing they were. keep up the great work. worth every penny. read more

I've been battling chronic illness caused by mold for years, so I know firsthand how serious it can be. That's why I reached out to Mike and his team at Fast Mold Testing to inspect my apartment. Even though I have a bit of a spidey sense for detecting mold myself, I wanted a second opinion to ensure my space was safe. From start to finish, Mike and his team were thoughtful, thorough, and efficient. They used a range of advanced technologies--including air sampling, swabs, and thermal meters to detect moisture in the walls--and provided me with a comprehensive report of their findings. Thankfully, the air samples came back clean. However, they did discover mold on my windows that I had completely missed. Thanks to their findings, I was able to address it quickly and easily before it turned into a bigger issue. I'm so grateful to the team for giving me peace of mind during the rainy season. Having worked with many mold detection professionals over the years, I can say that Fast Mold Testing is one of the best. If you suspect mold in your home, I highly recommend their services--you, and your health, will thank you for it read more

We recently had Fast Mold Testing assess the mold levels and air quality in our home in Carmichael, and the experience was outstanding from start to finish. Michael, the data scientist who conducted the testing, was incredibly knowledgeable and professional. His background in Biology and Chemistry was immediately apparent; he not only performed a thorough examination of our home but also took the time to explain the process in clear terms. He pointed out key indicators (red flags), walked us through the testing tools, and even shared preventative strategies to avoid future mold-related issues--something every homeowner should know. We received our results quickly, along with a comprehensive explanation and a detailed final summary that helped us fully understand the findings. Michael's approach was not only technical but also thoughtful, which gave our family real peace of mind. Absolutely a great experience, Fast Mold Testing, and Michael exceeded our expectations. Highly recommended! read more

I don't usually write reviews, but this one truly deserves to be shared. Michael showed up at a time when I was overwhelmed and unsure who to trust after dealing with conflicting inspection reports and months of health issues in my home. From the moment he arrived, he treated the situation with the seriousness and compassion it deserved. He was patient, thorough, and honest -- no guessing, no brushing things off. He explained everything clearly and made sure I understood what he was finding as he went along. For the first time in a long time, I felt like someone was actually on my side and cared about getting to the truth. His report not only gave me answers, it gave me proof -- and that made all the difference in how I was able to move forward. If you're dealing with something as stressful and scary as mold, I can't recommend Michael enough. He's professional, genuine, and truly trustworthy -- the kind of person you hope shows up when you need help the most. read more

Buyer beware, This is now the third company to open up with Mike Nguyen and Doug Paule. They claim to sell an A.I. Microscope that processes air o cells for mold and asbestos. I warn you, they will sell you a Microscope for $15,000, then tell you if you spend an additional $10,000, you'll have unlimited usage, with a no per sample cost. They then will close the company they sold it to you under and open a new company and extort you for more money to continue having access to their platform. Doug Paule contacted me late 2023 and demanded I spend an additional $10,000 for use of the service for three years with a company called frontier. Now five months later, I'm getting hit with this company doing the same thing. I warn you, do not purchase a Microscope from this company, you will absolutely regret it. Between this and the microscopes always breaking, save your money, you're better off using a lab to process your samples. read more

Fast Mold Testing really came through for me when another mold inspection company ghosted me last minute. I was dealing with a difficult situation with my landlord, who refused to fulfill maintenance requests, and I needed help quickly. The dispatcher was extremely helpful and took the time to listen to what I was going through. He clearly explained the process, the timeframe, and made sure to schedule an inspector before my deadline. Steve, the inspector, was great. He was thorough, informative, and walked me through every step of his inspection process while addressing all my concerns. Overall, it was a great experience during a stressful time, and their support made a big difference. I would definitely recommend Fast Mold Testing to anyone who needs reliable and professional service. read more

I am eternally grateful to Mike Nguyen (Chief Scientist) from Marvin labs for his excellent care of me. He came out on short notice for a mold inspection. He was punctual, professional, and provided a plethora of knowledge and support. He was really thorough, discovering a problem area that was not part of my initial investigation. The test results arrived quickly, and he personally contacted me to ensure I understood everything and gave any assistance I required. I highly recommend Marvin Labs' sophisticated AI technology for mold and asbestos detection. It is an exceptional, local company that values honesty, integrity, professionalism. read more

Professional and personable. I had a yellow powder of unknown origin and toxicity staining wood which I'd started to carve. Concerned that it might be mold, I contacted Fast Mold Testing (also listed as Marvin Labs) after efforts with other firms advertising testing services resulted in unreturned calls or unhelpful replies. Within a week, I got results back from Fast Mold Testing that indicated that the powder was wood-related, and not a mold, bacteria or pathogen. As a result, I was able to save the the rather expensive piece of hardwood and the work done on it. VERY pleased with their responsiveness and assistance! read more

I totally recommend Fast Mold Testing! After reading tons of reviews for different companies, I reached out to schedule an appointment on a Friday. They came out within 2 business days and I got my report within 24 hours. The report was so much more detailed than we were expecting and didn't leave me with any questions. They called a few hours after the report was sent to answer any questions I may have. The pricing was transparent and affordable and they never tried to upsell me. I have never had an experience as good customer service with another home service provider. 1000% recommend if you need a mold inspection. read more

Jordan and Mike have really cool equipment and tested all the areas of my apt of concern and even knew areas to look for that I was unaware. Then I got the results in a timely matter and am happy to know that my pets and I live in a mold free home. I learned a lot about mold to when they answered all my questions. It's so cool that Mike is a microbiologist. Thank you! I definitely will recommend to my friends when they move into new places or before they buy a home. Especially since I've seen so much mold in SF. read more

I highly recommend Fast Mold Testing (FMT). Alex was ready to send an inspector out the next day after our call. The inspector was informative, pleasant, efficient, and certified. His professional inspection, collecting of samples, and documentation resulted in a comprehensive report produced within a quick timeframe. FMT is a neutral inspection and testing business only, so there's no conflict of interest, which saves us thousands of dollars. We are very grateful for our excellent experience with FMT. read more

I am so grateful to these guys at Fast Mold Testing! They were great at replying quickly to my questions and were so friendly. When they came to the house they explained what they were doing and how the equipment worked (upon my nerdy request) and got the report back to us in less than 48h (which is insanely fast compared to traditional testing timelines that take weeks and weeks!!) thank you so much Mike and Fast Mold Testing team!! read more
