"Although my relationship with ARM started a bit rocky, in the end I was very happy with the service provided. After a ARM technician replaced a fan, the noise level in the surrounding rooms increased to a point where I wondered if I could sell the house. I got the impression from the technician who installed the fan and was told by another company's technician there probably wasn't anything I could do. But, Mike G, from ARM, was able to lower the noise to a tolerable level by reducing the vibration from the attached pipe by making small adjustments including re-positioning the fan, removing old clamps and adding foam. He patiently answered all my questions and explained what he was doing throughout the diagnostic. Although the noise problem was resolved, the radon level was still 10.8 pCi/L so ARM returned (with the original technician and Keith to add a second suction point. . I was very happy with their work. The pipes were placed in a way that is an unobtrusive as possible, are securely fastened and as I learned, have the right pitch. Before the installation, Keith explained what they did to determine where they thought the suction point should be, and after must have been a long day for them, made me feel it was important that all my questions were answered. My radon level is now .6 pCi/L! My only complaint is that it takes a long time to get appointments and for two of the visits they were a few hours late.. The cost of service is for the 3 visits which were 11/9/18, 12/26/18, and 1/30/19 and includes the cost of the fan."

Radon Detection and Reduction questions, answered by experts

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

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.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

You should have a professional test for radon every two to five years. A good rule of thumb is to get testing done every five years if you’ve never had an issue before and every two years if you have. You may also want to schedule testing if you notice symptoms of radon exposure or if you do intermittent DIY radon testing and notice changes in your levels between tests. If you have an active radon monitor, you can schedule testing if you notice levels increasing over time.
