"I had recently had my home inspected and was concerned about mold and what to do about it. I called Mr Standish because I had just used him for my home inspection, and he was again able to do the mold testing right away, and got back the results to me within a few days. It was helpful to have him answer questions about the test results, and the problem was minor, and something that did not require any major work(thank goodness!)Mr Standish is very knowledgeable about his work, and is honest, which I truely appreciate."

Radon Detection and Reduction questions, answered by experts

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

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.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

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.
