"I highly recommend Apex Radon Solutions. From getting the estimate to getting the work done, everything was just outstanding. Marco and his crew of 3 men showed up early and were all knowledgeable and extremely skilled. I had to install a radon fan and put in piping and electrical. They measured the piping with care and accuracy and did an excellent job with the installation. Iâ m truly impressed with the professionalism and quality of the work. They were also very reasonable with their prices. Thank you Apex for such great work."

"Mike was very friendly, and knowledgeable. He inspected the entire house and sure enough he did find mold in our basement. His own reports helped us understand the Lab reports and he advised us on how to remediate the problems in our home. I highly recommend him for any inspections you need"

Radon Detection and Reduction questions, answered by experts

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

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.

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.
