"Alex and his crew showed up exactly on time and were very professional throughout the whole process. They asked me where I wanted the exhaust pipes placed as there were many options. After the work was completed Alex left a radon testing canister and explained how to use it. The pCi/L reading before the mitigation was 7 pCi/L and after it was < 0.4 pCi/L. To top things off, Alpha also has a great warranty. I couldn't be more pleased."

"Fantastic experience from beginning to end! Communication was top notch. The installation went very smoothly, and the explanation by Mike (Junior) was appreciated as he and his partner worked through the process. We would recommend this company 1000%. Also, our radon level went from 11 to 0.4."

"I had a really good experience with Tom O'Connor. He scheduled quickly and arrived on time. He had me stay with him during the inspection and pointed out things as we went along. He showed me problem areas, explained why they were a problem, and suggested how to fix them. He also reviewed maintenance of things like the boiler and air conditioning. His report arrived on the day he said it would be complete. When he returned in a few days to pick up the radon test he also completed a portion of the inspection of the roof that he couldn't do initially because of snow. His report reflected everything we had talked about and did include the home maintenance points as well. And the report is easy to understand. He confirmed for me that I was getting a good, solid house and that the things that need to be fixed are manageable."

Radon Detection and Reduction FAQs, answered by experts

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

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

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.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.
