"They came back and checked on it when the levels weren't quite what they should be. I only have good things to say about them. They were very professional and knowledgeable. They seemed to have a lot of information about radon and how to have it removed from our house, and keep the levels down. The price was reasonable."

"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!"

"Neil is fantastic. Similarly to my last experience with him, he was prompt and professional. He had his septic resource properly scheduled, whom came out and did the septic test on time and were great to work with. He again explained everything as he went along, and again got the main home inspection report back to us the same day! He did a larger battery of tests than last time for us, and all results came back in a few days and were explained to us. Again, he offered his services to answer questions unrelated to home inspection if the need arises. We also had some concerns over some attic insulation, which he had tested for asbestos free of charge. I would highly recommend Neil!"

"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 FAQs, answered by experts

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.

Yes, many systems include warranties for performance. Confirm terms with your installer.
