"Very easy to get an appointment on short notice when I had limited time to get a radon test done in the process of purchasing a home. Their price was also slightly lower than an estimate I'd received from another company, and the technician was more thorough about explaining the process than the other company I considered."

"It was a very good service. It was nice and quick. He provided the details and he found the issue, he provided the feedback of the house to the previous owner and there is no issue. He is precise and specific, inspect every detail of the house, he helped us to estimate the furnace, old pipes before gone into this thing, and it is very helpful to us a lot. I would recommend him to any other people who would be needing any inspection in their real estate property. Very professional kind of customer service. Very good price and very affordable."

"Chuck asked all the right questions before giving a quote and gave us multiple options to address the problem leaks. His serviceman, Josh, was courteous and professional, clean and efficient. They filled two basement cracks with the injection sealant and we are pleased with the results. I would use them again.
