"I was very pleased with Kevin Leonard.  He was very thorough and I was really impressed that he was over detailed versus under detailed.  I appreciated having all that extra information that I wouldn't have expected.  I got him off Angie's List.  His price was very fair."

"Jon Helton and his son team member Zach were professional and thorough in their inspection while at the same time friendly and easy to talk to and ask questions. In addition to the inspection and samples he took for the lab, Jon gave us several helpful tips and suggestions for making the house marketable. I would definitely use Jon Helton and Home Team Inspection Service again and highly recommend them to anyone needing any type of home inspection, including buyers and sellers."

"He called me 35 minutes before the scheduled period that he would be there promptly at noon, which he was. He did a great job, getting out a couple of stains and was done within an hour. The only caveat is that they are not set up with credit card machines yet so I paid him with a check. Great job!"

Radon Detection and Reduction FAQs, answered by experts

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

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.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

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.

The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.
