"RADON SYSTEM WAS NOT WORKING. (Installed by another company years ago). The phone contact was pleasant and efficient. The Technician came on the agreed day and the agreed time: he explained what was wrong, explained the options, then repaired the system so it is working better than it did when first installed."

Work was done promptly and the crew was friendly and thorough.  They installed a cap over the floor drain that prevents air from infiltrating from the foundation drainage system while still allowing any water from the basement to escape should the washer overflow or a pipe break, etc.  As a result (and side benefit) my basement is less humid and no longer has that occasional musty smell.

Six months later and everything is working fine.  A retest for Radon showed virtually no presence whereas, before, tests showed a rather high concentration.

"In both spoken and written communication, this company was extremely professional. In the end they were a few thousand dollars higher in their estimate than the company I went with. If not for that I would have gone with EJS and I wouldn't hesitate to mention them to friends and family. I wanted to give them a good review here simply due to the level of courtesy, promptness, and professionalism they displayed.

Radon Detection and Reduction questions, answered by experts

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

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

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

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.
