"William was a kind, knowledgeable professional with a lot of experience and who paid attention to the details of our particular space. He gave some solid advise during his visit and delivered a detailed report of his findings after running the tests. I definitely recommend him and would call him again if ever I needed any other testing done. Also, did I mention he arrived at our house within one hour after I contacted Angie's List?"

"Its been over a year now since having our system installed by Southern Radon. Previous owner of our home had a system placed before our closing using another company but our numbers remained high. After reading the good reviews on Angies list, decided to call Southern Radon and ask for help. Matt visited with us, brought his detector, was able to target a few hot spots and we worked from there as far as how the system should be set up. Matt was awesome, has an amazing amt of knowlege about radon, asked all the right questions and seemed to be able to easily assess our needs. Over this year we have had many contractors visit, assess and make repairs...Matt stands out above them all. Our system works well and we have had very low readings which are a great relief ....The team that was sent to us to do the work I would rate B...a little sloppy ....didn't cover nearby area to protect or prevent a mess, as i remember some debris shooting out ...onto floor and walls and storage...would have been better if they were proactive and covered the areas that could possibly be affected...."

Radon Detection and Reduction FAQs, 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.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.
