"A1 and Andrew were great. Returned my call right away, gave me a fair bid, what I should expect, and a date to come out. They called ahead of time, and did quality work. Don’t hesitate to use them. I got lucky. I found out I had lung cancer and did a radon test. Don’t hesitate to do a radon test, and use A1 if appropriate. Thanks."

"Sam was on time for the estimate appointment that was scheduled. He was very friendly and professional. He was not pushy in any form. On the day of the scheduled service appointment he showed up ready to work and was again very friendly and easy to communicate with. He got the work done in a very reasonable amount of time and his electrician showed up on time and was the same. We will have our after mitigation radon testing done and I will update my review then."

Radon Detection and Reduction FAQs, answered by experts

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

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.

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.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

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.
