What is radon?

Radon is a cancer-causing, radioactive soil gas. It is colorless, odorless, and tasteless. Radon is estimated to cause thousands of deaths each year. When you breathe radon-contaminated air, you are increasing your risk of lung cancer. In fact, the U.S. Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today--just behind smoking. If you smoke and your home has high radon levels, your risk of lung cancer is especially high.

While our primary service is radon reduction, we have also addressed other soil contamination pollutants such as methane from nearby landfills, pesticides from lawns and farmland, C0² from abandoned strip mines and volatile organics compounds from nearby factories and dry cleaners.

We called a couple companies for estimates. Radon Systems was slightly higher, but we were impressed with the quality of the explanation of what would be done and what to expect. After the evaluation we were able to set an appointment within a couple weeks. Technicians came at 8:30 (as promised) and installed a fan and a sub-slab suction system drawing from three points (one basement, two in crawl spaces), leaving an adapter in case they need to add an additional pipe in the future. They left a radon meter and were gone by noon. Five days later the meter was picked up and read. Our radon levels had dropped from 20 to just under 4, which is the guaranteed level. They recommend we have our radon levels tested again in the winter when the house is closed up longer, and if the levels are higher than 4 they will come out at no additional charge and do whatever needs to be done to get the level within the limits.
