5 Microns Inc. Asbestos, Mold, Drinking Water, Radon, Air Quality Testing Lab at a glance

Customers frequently praise the company for punctual scheduling, clear communication, and rapid turnaround on test results for mold, asbestos, and water quality. Reviewers note that staff provide detailed, easy-to-understand explanations and reasonable pricing, often completing same-day or next-day appointments. However, a recurring criticism involves property damage caused during sample collection, where the company allegedly refused to repair significant wall and carpeting cuts, leading to financial disputes for affected clients.

Response from the owner · 8 months ago

This review is from an individual who was not our client. Our services were ordered and paid for by a third party as part of a real estate transaction that did not proceed. Asbestos surveys require limited invasive sampling in accordance with industry standards, and no repair or restoration work was contracted. We stand by our work and professionalism.

Response from the owner · a year ago

Orel, upon looking at our records, we don't see you in our system as a customer, it may be because you did not fill out the COC correctly and followed the drop off instructions, which could delay the process or have your samples rejected by the lab. When we are unable to process samples as expedited, we never charge the associated fee. Additionally, the lab had a computer network outage for the past week and the issue has caused major delays in providing test results, as well as the inability to process new samples. The lab is working on the issue and we expect service to resume sometime this week. Thank you! Pascal

⭐️⭐️⭐️⭐️⭐️ I had some concerns for mold in my office after gone through some water damage a year back, and I contacted 5 microns, and they came in the following day and ran all the necessary tests. A couple days later they emailed my results with the breakdown of everything I needed to know and how to take care of my concerns! Pascal was also very professional! Highly recommend!
