"This is the third time I've had Joseph perform an inspection for me in the last three years. You will find my previous reviews elsewhere on Home Advisor. His first inspection saved me from purchasing a house with many issues that the sellers failed to disclose. They initially declared that they would not negotiate on anything, but when he was finished they were rushing to backpedal and begged me not to cancel my offer. The sale was cancelled the same day he was done with his inspection. His second inspection ended in my purchasing my current home, and after three years I remain very satisfied with the purchase. This latest inspection was done in order to renew my insurance. I was asked for a 4-point but based on his expertise, he recommended I also do the wind mitigation since it might be asked at some point. Turns out, it will be needed after all, and his recommendation saved me from having to do this twice. So I have used Joseph's services for years, and he's always delivered even if asked to do so in short notice, with time constraints, while being flexible and accommodating when it comes to scheduling the work. I haven't had reason to complain about his services yet, and I will continue to call him first whenever I require any sort of home inspection."

"When Mr. Arnett called me to discuss the project, he was very friendly & helpful. He explained exactly what the test for asbestos would include, the time frame for the test, the cost, & shared general information about asbestos that helped me understand why it was so important for me to proceed with having my ceiling tiles tested. I felt like I received great customer service from Mr. Arnett & CDA Envrionmental!"

Radon Detection and Reduction questions, answered by experts

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.

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.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.
