We are a full service property maintenance company. In addition we complete demos and complete remodels/builds as well.

"The work was top-notch, but their internal and customer-facing communication is weak. 90% of the job was as expected, but the last two items (shower doors) were installed without us approving the particular door. The owner will say they were approved, but that's not the case. One door we never saw pictures of at all, and for the other we got two cellphone pics of a computer screen saying "this is what we typically install." A month later that ultra-modern looking door was on the wall in my old farmhouse. Complaints on my part were met with threats and bullying until I paid the full balance. I finally decided it was worth missing out on the shower door to get rid of the guy. In the process of the job, I got emails from one person in the company about things that had already been decided by someone else, so it was obvious that the internal communication was weak as well. Glad I can be rid of this company. Too bad because the people they hired to do the actual work at the house were wonderful."

Radon Detection and Reduction questions, answered by experts

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

No level of radon is technically safe, but because it’s everywhere—even in the air outside—it’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.

The short answer is no, air purifiers do not help with radon. While they certainly can improve the air quality of your home, they only clean pollutants from the air. Radon is radioactive, and it isn’t affected by the same filtration systems that handle other airborne particles, like dust and mold. The only thing that works is a radon mitigation system.

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.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.
