"Super customer service! Everything was totally explained to me and what needed to be done on installation. Brett was very informative & by the time he explained everything to me, I didn't have any questions. Brett was very professional but also easy to talk to. I love to support local businesses & EEHI LLc is that kind of company. All work was guaranteed. I strongly suggest you book an appt. with EEHI. My radon count went from a 10 to a .02 when he came back for final reading! I feel so much safer now! Super company & Brett was fantastic! Book with this company because they are so honest!!

"Adam and Nick arrived on time and performed the fan installation quickly and efficiently. The men acted as a team and helped the job to go faster. After seeing how the job went, we asked Adam to look at another project and after hearing his diagnosis and estimate contracted with him to do another job."

Radon Detection and Reduction questions, answered by experts

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.
