"Sidad did an awesome job of addressing Radon issue in the home I recently moved in to. He filled visible cracks in the basement, replaced the sump pump pit lid & sealed the same, in addition to the radon mitigation system installation. He has a friendly approach & does his best to meet his clients needs. I was completely satisfied with his work."

"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."
