Q: How much does a radon test cost?

• <div><p><a href="https://www.angi.com/articles/how-much-does-it-cost-remove-radon-gas.htm">Radon testing costs</a> around <b>$450</b> on average, but you could pay between <b>$150 and $800</b> for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge <b>$50 to $100</b> extra.</p></div>

Q: What is the biggest source of radon?

• <div><p>The soil beneath your house is most likely what&rsquo;s causing an increased level of radon. This is because soil holds radioactivity for a long time and it&rsquo;s also what most buildings are built on. Another common source of radon is water from a source that hasn&rsquo;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.</p></div>

Q: How do I know if I have radon?

• <div><p>To determine whether you have radon in your home, you must run a test. Radon gas has no odor or color, so you won&rsquo;t notice a concentration of radon. You could purchase a DIY test at a local hardware store, but it may not deliver completely trustworthy results. The best way to test and receive accurate results is to hire a <a href="https://www.angi.com/nearme/radon-testing/">local radon detection specialist</a>.</p></div>

Q: What factors affect testing costs?

• <div><p>Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.</p></div>

Q: Is there a safe level of radon?

• <div><p>No level of radon is technically safe, but because it&rsquo;s everywhere&mdash;even in the air outside&mdash;it&rsquo;s impossible to avoid entirely. Instead, the Environmental Protection Agency encourages taking preventative measures if the levels of radon in your home rise above 2 pCi/L. (For reference, the average radon level in homes across the United States is 1.3 pCi/L.</p></div>

"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."

"I recently had a mold inspection done at my home by Green Home Solutions and couldn’t be more pleased with the experience. From the very first contact with Alissa, the customer service was top-notch — she was so polite, responsive, and easy to communicate with. She was happy to answer the several questions I had prior to scheduling and I was quickly impressed with her knowledge and expertise. Alissa scheduled my inspection promptly, which I really appreciated. Both Alissa and Brian showed a high level of professionalism and reliability throughout the entire process. Their industry expertise was evident in how they conducted the inspection, explaining everything clearly and answering all of my questions with patience. I was especially impressed with Brian’s quality work and attention to detail. He didn’t miss a thing and made sure to check all the possible problem areas. They also use organic, plant-based, and non-toxic products, which was a big win for me and my family’s health. Their pricing was fair and transparent — no surprises or hidden fees. After the inspection, they provided a helpful and thorough follow-up and inspection review, breaking down the results and walking me through the next steps. The end result was a clear plan of action, and I now feel confident that the problem is resolved. It can be hard to find companies you can truly rely on, but this one is absolutely trustworthy. Highly recommended!"
