"I would definitely recommend C&S home inspections! I had a Radon Mitigation system installed and had nothing but a positive experience. They are extremely knowledgeable and friendly. They explained everything I needed to know thoroughly, which is important to me. Their prices are also the best have seen in my area. If you need a Radon Mitigation System, I highly recommend."

"Tom was wonderful and extremely thorough! He explained everything as he went along and I left feeling like I really knew the ins and outs of the property. He was extremely personable and very professional. He called to schedule and follow up prior to the date of the inspection. I felt confident in him during the entire process. I would recommend him to anyone."

"Hired Terry for a home inspection. I'm buying a home that i know needs a little tlc. I wanted the peace of mind that I'm not getting into something over my head. Terry was very professional. He arrived on time and did a thorough inspection. He found some things I hadn't seen on my 2 previous walk-thrus. He had the full report completed within 2 days. It's a very detailed report. All in all I would definitely recommend Roof 2 Basement to anyone who needs a thorough inspector! I see it as money well spent..now I know exactly what I'm getting into!"

"If you’re looking to get any type of inspection or home services then look no further. I recently became a customer of Justin Ake after trying to get my soon to be home inspected. Rick was dispatched to the property and went above and beyond, both explaining the inspection process and showing me key points in the houses plumping and drainage systems. As well as providing information on other tests and services the company performs. I don’t normally write reviews, but I have to say this is one business that takes pride in their trade."

Radon Detection and Reduction FAQs, answered by experts

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

Installation typically takes 1-2 days, depending on the system and property layout.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.
