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: How do I know if I have a radon problem?

• <div><p>The only way to determine if you have a radon problem in your home is to have professional testing done. You can buy DIY radon test kits, but these are sometimes inaccurate in certain temperatures and humidity levels, and they don&rsquo;t paint the entire picture in terms of your radon exposure. Scheduling testing once every two to five years is best. You can also look out for the following symptoms, which, according to the American Cancer Society, are symptoms of radon exposure:</p><ul><li><p>Shortness of breath</p></li><li><p>Cough</p></li><li><p>Tightness in the chest</p></li><li><p>Difficulty swallowing</p></li><li><p>Hoarseness</p></li></ul><p></p></div>

"In February 2021, we had our hardwood floors buffed and recoated before moving into our home. The result was good, but over time it became clear that our regular bi-monthly cleaning needed to be supplemented by a professional cleaning and restoration service. After obviously insufficient research, on May 9th, 2023, we retained COIT cleaning and restoration to complete this cleaning and restoration on an estimated 2,451 square feet of wood floor. After completing about one-third of the job it became clear that in certain areas the machine being used was removing the coating applied in February 2021 and the COIT operators suspended their cleaning activities. COIT did not charge for removing the coating and of course, blame was attributed to the contractor who completed the recoating in February 2021. Several days later our feedback was sought regarding our satisfaction with the COIT service provided. Obviously, this feedback was not entirely positive. On Sun, May 14, 2023, at 11:07 AM, we received an email from Carl Moore, Operations Manager of COIT asking for “a brief description of the situation” and “any pictures you may have.” This was provided on May 15th. After a month of silence, we followed up with Mr. Moore on June 15th. Mr Moore’s response was “It is clearly noted on the work order to proceed with a customer risk signed.” The disclaimer speaks for itself “No satisfaction is guaranteed.”"
