Expert Radon Testing in Greensboro, NC

Radon testing is the only way to know if radon is present at unsafe levels in your Lewisville home. Radon is a colorless, odorless gas that can enter through foundation gaps and build up indoors without any visible signs. The EPA sets its action level at 4 pCi/L, meaning homes at or above that reading need attention. Lewisville sits in Denton County, an EPA Zone 3 area where average indoor levels are generally lower. However, the EPA recommends testing every home regardless of zone, because individual readings vary from house to house based on soil, foundation type, and ventilation. Lewisville's predominantly slab-on-grade housing stock can still trap radon under the right conditions, especially when windows stay closed during hot Texas summers. Clean Air tests the lowest occupied level of your home, following EPA-recommended protocols. Results give you a clear picture of your indoor air quality so you can decide on next steps with confidence. Call us to schedule your Lewisville radon test.

I highly recommend Rick and his team for any basement or crawl space job. They did a crawl space encapsulation for us with high quality work at a great price. They went above and beyond to make our house safer from mold and dust adding a dehumidifier. Our house now feels cleaner, less dust and the humidity at the proper level. Rick, Noah and Stephen were great to work with, solved problems, and were able to get the job done quickly. . This was one of the best investments we have done for our new Irving park home. I cannot recommend them enough.

Rick and Noah are the BEST! They answered all of my questions and were super knowledgeable. They made me feel super confident in my decision and I knew I had the right guys for the job. They worked efficiently professionally and were super kind. The communication was top-notch and the work was even better.

Noah and his team “under promised and overperformed” they totally cleaned out our crawlspace did some mold remediation, and completed the encapsulation as well as thoroughly cleaned the ductwork ,trunk lines, and all vents.End result was perfect. It’s always nice working with people that deliver more than expected. Very courteous, attention to detail are all the things that they delivered when they performed our crawlspace, remediation, encapsulation.

Rick, Noah and all the crew at Clean Air did an outstanding job on our house in Greensboro, NC. Called for a quote and Rick was out quickly and gave us an outstanding price on a full crawl space encapsulation and cleaning of the vents/returns. The employees were prompt, easy to talk to and answered all my questions. They did a thorough job removing the old insulation, soda blasting any mildew that had formed over the years and checking for any other potential problems. They have been out or have been in contact several times to check on any concerns, which there haven't been any. I couldn't have gone with a better company to address all of our crawl space concerns. Peace of mind has been priceless. Thank you again to the guys at Clear Air!
