Making homes safe for you and your family is our passion. Radon Engineering Consultants has been providing radon testing and mitigation in the valley for over 25 years. You don’t survive in a small community like ours for that long unless you’re doing something right.

Because radon in homes is the second leading cause of lung cancer after cigarette smoking. You can watch a very informative video by Dr Oz discussing the #1 Cancer Risk in Homes here. http://www.doctoroz.com/videos/1-cancer-risk-home-pt-1. You don’t have to live with a radon problem. A simple and inexpensive radon test can tell you if your home has elevated radon levels. Radon Engineering only uses Continuous Radon Monitors (CRM) to provide the most accurate radon readings and can provide the results in just 48 hours. And, if your home does have radon above the EPA’s recommended levels, we will provide a free evaluation of the causes and propose an affordable and quick solution. Radon Engineering Consultants is certified by the National Environmental Health Association (NEHA) as approved Radon Mitigators, and has successfully reduced the radon to safe levels in thousands of homes over the last 25 years.

Radon Detection and Reduction questions, answered by experts

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.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

Professional radon detection involves placing test kits in the lowest lived-in level of the house for a period, usually 48 hours to several months, followed by lab analysis of collected data.

A radon test has no effect on humans—only the radon in the air does. The test does not redistribute the radon that is already present so yes, it’s safe to be around the testing kit even if it isn’t safe to be in the room itself. The test absorbs and measures the radon, but doesn't absorb enough of it to make the room any safer.

It is worthwhile to get radon testing done, especially if you haven’t in the past and don’t have active radon monitoring set up in your home. According to the American Lung Association, radon is a potential issue in all states, and testing is the best way to determine if it’s a current problem in your home. Radon testing includes professional tests that determine ongoing radon levels in your property, and it usually includes a mitigation protocol to help you decide what measures to take to protect your home and household members.
