"Jose Rodriguez was prompt, professional, and fast with results. He was there when he said he would, went there the next day after I called, and provided the results on time. As a real estate professional I know I'll need the services again and I know that he is the person I will be calling. Thank you!"

"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."

"I think this guy did a good job. My In-laws thought he was a little fussy, but I'd rather have every little thing noted. I'd rather be able to decide what's important. The report was pretty concise, and the summary was pretty good as well. I recommend him."
