"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

Radon Detection and Reduction questions, answered by experts

Avoid opening windows and keep doors closed during testing to obtain accurate readings.

Radon is a colorless, odorless gas that can cause lung cancer; testing ensures safe indoor air quality.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.

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.
