He was so helpful and informative with his advice and observations. He responded promptly when I called him and came out right away. We will get our results within a few days. He was extremely knowledgeable. He let us know that he only did the testing and would not be fixing any of the issues if we have any. I feel that was a big plus in working with him because no conflict of interest with testing and repairs. He did offer logical recommendations for minor potential issues. Would highly recommend him.

Cheryl at Mold Busters is a consummate professional. She handled the inspections for two of my…read moreproperties and her attention to detail was outstanding. What I appreciated most was how she translated technical data into actionable information, making sure I and my clients understood the results of every test. She is clearly an expert in her field and takes the health of her clients seriously. Prompt, incredibly detailed, and a pleasure to work with. Five stars all the way.

She explained what she was seeing in a calm, science-based way, and her recommendations focused on the root cause (moisture/ventilation) instead of fear, unnecessary work or upselling. Her pricing is reasonable and her service offering provided exceptional value. I especially appreciated how clear and practical her guidance was, and that she prioritized what actually mattered for my situation. Her work and report were thoughtful and tailored, with straightforward explanations and actionable steps--not generic boilerplate. If you're trying to figure out whether you have a real issue (and what to do about it), Cheryl is the person you want. She is the only person I would ever trust, work with or recommend for this type of testing, guidance and work.

It was all resolved in less than 48 hours once I called them, including a site visit by a professional for sample collection and field survey, testing, and finally a well-rounded professional report.

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

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!

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.

It took me about 2 years to fully recover, so I am extremely hesitant to rent anywhere that has the faintest musty odor. I first hired Graham in Fall 2020 when I was in a cute Berkeley duplex that had an odd odor in the living room. I hired him again when I moved into a condo rental across town that I only realized had water damage after I'd moved in, because it had been tenant occupied when I toured it and their possessions hid much of the water damage. I most recently hired Graham in 2023, after historic heavy rains caused water damage to a window in the Edwardian SF rental I was living in. I had him come by after the window leaks were repaired but before the repair person closed the wall up. Graham gave me the piece of mind that the repair was done correctly and that the apartment otherwise was in good condition with respect to his area of expertise. Graham has always been professional, extremely knowledgeable, thorough, and helpful. I have recommended him to several friends and anyone else who mentions the slightest concern about mold or water damage in their home.
