Carl is very professional and personable, arrived on time and delivered what he promised. The lab's air quality report is superb - very reliable and informative. My boyfriend and I have used his services in three occasions and we don't have any complaints. He is also a pleasure to talk to! I highly recommend his testing services for any air quality, mold or VOC issues or just to find out how healthy the air in your home is.

Real Stories from Our San Francisco Clients

"Extremely thorough and knowledgeable! Carl has 30+ years of experience, and I was beyond grateful he offered to come make a house-call on Christmas Eve. From the moment he picked up the phone, listened to my problems, and ran me through different test options, I knew this guy was the real deal. He is honest and completes honorable work, and isn't trying to swindle you like other guys in the business. He stayed for 3+hours completing multiple tests to get to the bottom of the issue behind my inability to breathe at home, and he's great company too. One of the more enjoyable Christmas Eves I've had in a while. THANKS CARL!"
Meredith C.
"Carl was extremely friendly, punctual, and made a terrible situation (finding mold in our apartment bedroom) so much less stressful. I had trouble finding a mold testing business to come for a same day appointment (actually, finding anyone within a few WEEKS of availability was difficult). Carl agreed to drive down to MV just a few hours after my call. He taught me how to read the report once it comes and even gave some tips on how to present a case if the property manager puts up a fight. So thankful! Thanks for the great conversation and quick service, Carl!"
Pam P.
"Carl was exceptional in his responsiveness and analysis of what was going on with my house. He pointed out the sports that could bring moisture into the house structure. Thanks to him, I discovered, and then fixed, a leak that had been going on without my knowledge. Carl was able to come by the same day I called for a quote, and did the test right away. He offered additional services which he did exceptionally well, and took him more hours that initially planned. He followed-up after the work was done to make sure everything is good. Carl is committed, hardworking, honest, knowledgeable, helpful and simply a nice guy. I recommend him highly to anyone, whether a homeowner, or a business owner, who needs a thorough environmental quality testing done. A++ job well done."
Rania S.
"I wanted to get a mold test to better understand the air quality in my house. I chose Carl because talking to him on the phone I could tell he was not only knowledgable but honest. I appreciate that his company only does testing and not the work, so they do not have a conflict of interest. Carl was able to schedule me quickly to get the test done. While collecting the air samples, he taught me a lot about mold risks and suggestions to make the house more resilient against moisture. Luckily, we did not find mold in the house. Good news! I would recommend Carl to anyone looking to get air quality testing done."
