Carl Gibbons with A-1 Certified Environmental Testing did a thorough job of inspecting and an excellent job of explaining everything. I highly recommend his service to other people and glad to have Carl back, if needed.

Carl came to my home and walked me through the entire process of checking for mold behind my walls and ceiling. He explained the process and demonstrated how his space-age equipment works. I found him to be both friendly and professional. I highly recommend that you use his service.

Carl was knowledgable, thorough, and easy to work with. He appears to know his stuff, and the results proved him right. I'd ask for him again! Thank you, HomeAdvisor.

Carl was very helpful and he explained everything he was doing step by step. He also, encouraged me to follow him room by room while he did his inspection. He's a wealth of information and a pleasure to work with. He was extremely thorough and his knowledge of the industry is impressive. I would highly recommend A-1 and I would most certainly use them again.

Carl provided very professional service. He explained everything that he was doing and made sure that I understood the methodology. Being anxious to know the results of the testing, the lab that he worked with had the test results back to me within 3 days.
