"Mark is very thorough and explains findings well. Took his time and when he picked up the radon tests a few days later, he took another look at the exterior as it was raining the day of the inspection. Great customer service."

"I had done some self testing so was aware that work was needed. SWAT got back to me within minutes of making my selection. The appointment was within days. The technician was very clear about options of placement. I had already upgraded the fan and outside pipe. He went to work and did a neat job. The best part is that my tester indicates that radon has almost disappeared."

"Great people, honest and fair. I have confidence that the system they installed is the best. Radon NC used top quality materials and their guarantee is comprehensive. I almost went with a "national" company but I compared their estimate to Radon NC and there's no comparison. Affordable Environmental Services guarantee their work and use the best materials, not the cheapest. I recommend this company!"

Radon Detection and Reduction questions, answered by experts

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

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.

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.

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 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.
