"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."

"John M. was courteous, timely, and professional in his inspection. He was upfront about the issues -- whether they are serious or minor, rare or common, and whether more specialized input is required. His written report was very well done and will serve as a great home guide for us in the future after we move in. Thank you!"

Radon Detection and Reduction questions, answered by experts

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

Yes, many systems include warranties for performance. Confirm terms with your installer.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

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.
