Protection from radon exposure in Maryland

Radon is a tasteless, odorless, colorless gas that is the natural result of uranium decay in the soil. If your home has high levels of radon, you and your family could be at risk of lung cancer. In fact, radon is the second leading cause of lung cancer in the U.S. and is responsible for approximately 21,000 deaths per year.

Your local radon mitigation contractors, highly trained by National Radon Defense, want to inspect your home to identify the radon levels and determine whether radon abatement is necessary. These radon experts can provide industry-leading mitigation services to maintain a healthy radon level within your Maryland home.

Project Location: Andover Road, Forest Hill, MD 21050

Comment: Radon is registering 8.4 in my house. How much will this cost me to get it fixed?

Project Location: Chequers Ct, Bel Air, MD 21015

Comment: We recently conducted a short-term radon test in our basement... test results came back at 10.2 pC/L. I just sent back a second test kit to Alpha Labs and should see the results within the next few days. However, I suspect the second test to be close enough to the first test to warrant a radon mitigation system. Please provide me with a quote and some information on the type / style of radon mitigation system that would be required for my home. Please note that home has ~ 3700 sf of finished space (above and below ground).

Project Location: Coopers Lane, Worton, MD 21678

Comment: We have a known Radon problem in the basement, which also has an existing perimeter drain, leading into a sump. However, this drain is not sealed, and is open to the soil below, presumably allowing Radon gas into the basement. The basement has no known water problems, but we are trying to mitigate the radon, while working with the existing perimeter drain.
