A1 Certified Environmental

I live in Stockton and provider lives in Bay Area. Provider was at my house in less than 4 hours after I called him. The price of his services was less than what my contractor would have charged just for the testing. Results of testing were back to me within a few days. I was extremely impressed. It was important to me to have an independent company do the mold investigation (not the company that will eventually fix the damage). I wish that all professionals with whom I have dealt were as professional and proficient as A1

I have used this company more than once. I have always received excellent customer service!!! The reason that I originally used this service was simply because I had done research and A1 was willing to beat any other company's real price. The tech was very up front, and to the point. I didn't always hear what I wanted to hear, instead I was told the truth! He took time to explain the process that he was performing, giving me insight and a new understand when it comes to mold and the testing of it. A-1 Certified Environmental Services definitely lives up to it's name! A-1

Carl is straightforward and fair in his dealings with us. He was prompt and professional and knows how to do a good job.

Carl was very professional and accommodating. He was honest and communicated his suggestions and pricing clearly before testing so we were aware of the extent financial obligation. Even after the test results came in, Carl was very helpful in explaining the results and answering all questions we had, he even offered to answer any future questions we had.

Very professional and think they did a good job. Called right after I put in the request and was out the next time I could be there.

Carl is very knowledgeable, very professional and a pleasure to work with. His background in construction proved very helpful in our situation. We highly recommend A1 and Carl!

Carl was very informative, honest and thorough. He offered us a same day appointment which was great. He went above and beyond by not only testing our home but he also pinpointed the cause of our problem. We would definitely recommend him.

Carl is wonderful! Put some big fears to rest with his knowledge. I appreciate his professionalism.

Carl is very professional and friendly. He explained the entire process thoroughly. Any fears, concerns were alleviated by Carl's knowledge and expertise.

Carl was extremely knowledgeable in a field that most of us don't have a clue. He was honest and on time even with a long drive on his part. Also willing to come out on a Sunday to work around my schedule. I've worked in building contracting my entire life and if more people had the integrity of Carl, the world would be a different place. Thanks again !!!!!!

They were very good. I was very impressed and happily surprised.

Very professional and courtesy. The gentleman that came to our house was funny and very professional and was on time.

This company only does testing so there is no incentive to a failed test - this provides peace of mind. Very knowledgeable and honest - will inform you of your options and recommend what is best for you not the highest priced option to increase business.

Carl Gibbons is the most knowledgable, efficient, and professional mold tester out there. He is knowledgable beyond his job title, and shares his expertise with an articulate and down to earth portrayal of the facts you need to know when dealing with the serious health risks involved with mold exposure. Because of his accurate testing and kind and helpful advice, our family was able to get the proof we needed in order to understand the dangers of a mold infested house and relocate to a safe environment, thus avoiding long-term damages to our health. If you need a mold tester, Mr. Gibbon's is the BEST!

Very professional. Still waiting for results. Carl was professional and prompt.
