"adon After I contacted him, he responded promptly.  While evaluating the area that needed radon mitigation, he called to discuss an area that had not been evaluated by inspectors (not affiliated with him).  After accepting his price, we agreed on the day for the installation.  During the installation, he was respectful and communicative.  After completing the installation, he provided written warranties for me and the buyer.  I highly recommend Keystone Radon Mitigators.

"I could not be happier with this company. They did the work right away, even working on the weekends. They were very knowledgeable about what needed to be done and how to get the debris tested they have been very responsive. They have continued to be helpful to me in dealing with the company that left the silica dust in my home. You will not be disappointed if you use this company. I have never seen a company that is so attentive to your needs.

Radon Detection and Reduction questions, answered by experts

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.

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.

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.

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

Installation typically takes 1-2 days, depending on the system and property layout.
