"I recently hired Acceptable Environment to install a new radon mitigation system in my home in Warwick, NY, and I couldn’t be happier with the results. From the very first call, their team was professional, knowledgeable, and responsive. They walked me through the entire process clearly, answered all my questions about the system and what to expect, and scheduled the work promptly. The crew arrived on time, worked efficiently, and installed the new system with minimal disruption to my household. They went above and beyond by carefully sealing the basement foundation and taking every precaution to contain dust and debris. When they finished, they cleaned up so thoroughly that you’d never know major work had just been done — no mess left behind at all. The best part? The post-mitigation testing came back with radon levels at just 0.3 pCi/L — down from well above EPA action levels before the install."

Radon Detection and Reduction questions, answered by experts

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

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.

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.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.
