"We had a special situation, and Epic was the only company willing to come out to help us evaluate the best location for installation. Installer was great - he recognized asbestos tile on the basement floor, and recommended appropriate remediation service. System is basically invisible - no ugly pipe up the outside of the house! Follow-up test shows radon level reduced to well under recommended minimum."

"We had one little unanticipated issue and they handled it perfectly. He was by far the most reasonable quote I received and the quality was great. I thought he was very professional and very knowledgeable about radon. Before this experience I didn't know very much about radon now I know more about the importance of testing, and the safety of my home and family because of him."

"I worked with Pam throughout the entire experience. She was wonderful. She contacted me quickly to schedule an appointment and also scheduled radon testing on my behalf. We had to reschedule due to a snow storm, but she was quick to contact me and arrange a new day. On the day of the appointment, she showed up on time. We spent a few hours at the house while she inspected it. She pointed out a few issues here and there. As soon to be first time homeowner, I really appreciated this. She sent the inspection report the following day. It included in depth details and pictures.

"Hired for the convienience of their timely ability to install a radon system. The vent on the outside of the house is a large diameter, circular chimney that is very unsightly. Prices were a bit higher than other companies, but their ability to install quickly took precedence. In SWATs defense, I did not inform the company of my displeasure as the system was being installed as a condition of sale."

"Arrived on time. Got the work done in the time frame and cleaned up afterwards. Had to bury a pipe in the yard and they replaced the sod so you could barely see where it had been done. I got 4 estimates done and theirs was much lower for same work."

Radon Detection and Reduction FAQs, answered by experts

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

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.
