Customers say: True professional

"Jeremy was very professional and did a great job. He had reached out after I scheduled the original appointment to reschedule due to poor weather conditions. He offered to move the appointment to a date/time that he usually doesn t work to accomodate my needs. Once he had finished his work, he walked my fiance and I through everything explained it all very clearly. He also thoroughly explained the process for testing radon levels and getting test results back after the mitigation installation was complete. Would definitely recommend his services as he did a great job and his quote was very competitive."

"I had done two separate radon tests and knew the level was high. Bill came to evaluate where to place the system. He gave me a rough cost and time it would take for the install. He was able to schedule the install within a week. He arrived when scheduled. They did a very thorough job and cleaned up well after the install. It was hard to tell they were here. Very professional. The only knock I would have is that because they are quite busy, it is difficult to get an initial visit as Bill does the evaluation himself. You may have to call a few times and it was a challenge to pin down.

"They did a great job with the installation and made sure the Radon was under the level it needed to be. He had to make a couple of trips to make that happen but was very polite and profession through the whole process."

"The crew showed up at 7am, put out tarps and got right to work strippng off the shingles. The tear off was done by noon and they got to replacing shingles and adding the ridge vent. In all our encounters with the workers they were very polite and professional and answered our questions knowledgeably. They stayed until 8pm to finish the roof and then came back at 6am the next morning to clean up. 
Our neighbors have all commented on how quickly they worked and how good the end result looks. We absolutely would recommend them.

Radon Detection and Reduction questions, answered by experts

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

Yes, many systems include warranties for performance. Confirm terms with your installer.

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.
