Sam was very professional and performed very accurate testing as part of our home inspections during a recent real estate transaction. The test results proved to be very important and were later confirmed by follow-up testing by the homeowner's representative. We would not have known about the serious health concern without Sam's excellent testing. Thanks again!

Had a great experience with this company! I was concerned about some water damage in my home and I wanted to have that area tested ASAP for mold etc. It was very easy to get a hold of Sam and his team. They responded promptly and were able to get me on the schedule very quickly. Sam came out to do the testing. He was very kind. He explained the entire process well and took the time to check my whole house for any other areas of concerns. I received the results/report in a timely manner also. They were able to recommend a remediation plan and gave me a list of reliable contacts for the remediation. I would definitely recommend this company and I would definitely use them again!

Sam was such a pleasure to work with. He took the time to speak with me on the phone, he scheduled a time to come test, and he showed up. The report is very thorough, and he took the time to explain everything every step of the way. I reached out to another company prior to finding out about Sam, and I couldn’t get the others company to come. Sam also connected me with someone who can help me with my unique case. Thanks so much!
