"As a Realtor, Schan has done many of my clients' radon system install and they all were extremely please with his knowledge, install and his going above and beyond to make the system appealing from the exterior of the home. Many companies will not make the effort to ensure that the system does not look unsightly. Schan does and he is an expert at what he does. I would only recommend Schan to my clients!"

"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."
