"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!"

"The one they did in 2007 has held up, but the one they did in 2013 has not held up. They put a lifetime guarantee on their work, so they are going to fix it. They do excellent work."

"This business was highly recommended by my realtor. I hired this company to inspect the radon mitigation system prior to me buying a house. The owner, Sidad, was very responsive to my inquiries. The inspection price was reasonable, and he followed up promptly with the results on the inspection. I hired him to come out and fix the radon mitigation fan after purchasing my house. He was quick and efficient, and the price was reasonable. I highly recommend this business."
