"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.

"What a wonderful company! It's rare today to find a contractor that was so responsive to our call. Al came out the day after we spoke to him and took samples from various surfaces in our basement. Test results were back in 2 days and test results revealed the presence of mold in our heating room and in the basement bathroom. Al uncovered a leaking pipe from our sprinkler system. This leaking pipe was in a closed cabinet in the basement bathroom and probably would have gone unnoticed until October when our sprinkler company came to shut down the system. So our water bill would have skyrocketed and mold presence would have probably been much more extensive., We spend a lot of time in our basement gym and playroom as do our young grandchildren so we wanted the situation taken care of immediately. Our plumber came and repaired the leak and Al was able to squeeze us in within 2 of getting the leak fixed.. Al and his crew arrived as scheduled and within a few hours all the compromised areas were cleaned and treated. They were so quiet and worked so efficiently we barely knew they were in our home. They left the basement area totally clean and ready for use. We cannot speak more highly of J & A Environmental Services. The whole process from their initial visit to mold removal and mitigation took only a week and was totally seamless. We would recommend them again without hesitation. Thanks Al and crew!"

"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.

"I had a pipe burst in the basement of our rental property, Flood Crew was referred by our realtor. They arrived quickly after the pipe was fixed by our plumber, demoed, and dried out the areas, even handled packing out our furniture and placing carefully in a pod storage while the work was being done. They did mold testing and made sure everything was safe, the best part was that they dealt with the insurance and we didn’t have to do anything."

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, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

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.

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.
