Certified Mold Inspection & Testing in San Francisco, CA

"Through and professional mold testing! Got the results right away and they clearly explained what the next steps were."

"Fast Mold Testing was extraordinarily professional. After a Yelp inquiry, I was contacted (by phone) by a knowledge representative (Shantell). I loved this interaction because Shantell was prompt, courteous and really heard the services I was seeking. Shantell also followed up with a point of inquiry I had on a weekend. Plus, the technician was prompt and demonstrated a genuine expertise in the service. In short, Fast Mold Testing was responsive, communicative, knowledgeable and provided superior service I highly recommend their services."

"I reached out to Fast Mold Testing on November 19, 2025 due to some urgent, suspected mold issues with my apartment. The intake rep was really sympathetic with my situation and walked me through exactly what to expect during the process. I was able to get scheduled around half a week later on November 24. My inspector showed up on time, explained every step of his process, and was extremely thorough in every step of the way. I received my invoice the morning of November 26. I received my detailed results only 2.5 hours after paying my invoice. I am super impressed with the report - it's full of images and clear recommendations, which is so helpful. What was surprising to me, however, was that the inspector was an outsourced contractor. Ultimately, I'm extremely happy with how this went and recommend their services to others; I just wish they would have mentioned this during the first call."

"Fast Mold helped me when I urgently needed an expedited mold inspection. We discovered various signs of moisture damage prior to moving into our new place, a couple of days prior to our scheduled move-in , and were grateful to Fast Mold for coordinating a prompt and thorough inspection. Alex who handles their intake was able to secure my a quick inspection in a pinch. James and Alicia, our mold inspectors, were incredibly knowledgeable, thorough, and generous with their time and expertise. Michael who wrote up and reviewed the results with me was extremely thorough as well as generous with his time."

"I had an excellent experience with Fast mold testing inspection company. They truly went above and beyond from start to finish. They were extremely thorough, professional, and took the time to clearly explain the findings and what they meant for my home and family. Their attention to detail, honesty, and willingness to answer every question made a stressful situation much easier to navigate. It was clear they genuinely care about their work and their clients, not just rushing through an inspection. I highly recommend them to anyone looking for a knowledgeable, trustworthy, and detail-oriented mold inspection company. You won’t find better service."

"I contacted FMT requiring a second inspection of our home. I cant express how great full my family and I are that a company with such knowledge and passion was able to assist us. Josh was able to get an inspector out to our home within 24 hours of my call. Steve, the inspector, came to our home with such a short notice, which was not in his usual area. Steve was so thorough in his inspection and was able to walk me through the process. He also educated me on proper the remediation process, which was very helpful as the landlord seems that they are either not familiar with the correct process or they do not care about our health as FMT does. I recommend FMT to anyone who needs a mold inspection company."
