"It went very well. James Musarra is extremely easy to work with. He asked all the right questions and listened to my concerns. He came out to view the basement within 2 days and had a proposal for me within 2 days after. We were scheduled within 10 days and the work was done in a day with a quick visit from his electrician on another day to hardwire the fan. No mess, no fuss. There was no delay in my basement sheetrock project, as they were able to work on the other side of the wall where the fan went. The fan duct has to go above the roofline of my home and the placement that they chose was very unobtrusive. All in all it was a smooth, professional job. James always answered my calls or returned them the same day. As part of his service he includes a radon re-test to assess the effectiveness of the mitigation. I am happy to say the "after" radon level was 1.3 pCi/L."

"I had a great experience with Joe , getting a co-op unit inspected. His price was very reasonable and he was very accommodating when unexpected obstacles occurred on the day of the inspection. He was very thorough and knowledgeable. I love that he explained everything at the inspection, which was very helpful. Everything was also written out in a detailed report that he sent very promptly. We ended up not purchasing the unit. What really helped us with this difficult decision is Joe's leveled and unbiased relaying of what he found at the inspection. He didn't exaggerate any flaws for example. At the end of the day we feel like we dodged a bullet after the inspection and will definitely be hiring Joe again once we find a home to purchase. Highly recommend him."

"Olivier was terrific. He was incredibly thorough and left no detail out of his inspection or his report. He took the time necessary to inspect all elements of the inside and outside of the home, he was patient in explaining what he found, and he was able to put all his comments within a helpful perspective. I would recommend him 100% and would use him again without hesitation."

"The rep came out and reviewed the areas of concern.  He gave me an estimate on the spot. The next day I decided to go with JBH and the project was scheduled for the following week.  The workers arrived within the scheduled time period and they were very pleasant to work with. They were responsive, efficient and neat. The job was completed in no time.

"As a realtor, I found Rich from Expedient Environmental Solutions while searching for a client who needed mold remediation. He and his crew did an excellent job at a fair price. They finished on time and left the home clean. So, when I was looking personally to have basement waterproofing (interior french drains and sump pump) along with radon mitigation, I received 3 quotes, of which theirs was the most comprehensive plan, and again not the highest quote overall. They finished the work ahead of schedule by bringing four workers the second day, were respectful throughout and left the area reasonably clean. I'm confident that my days (and nights!) with the shopvac and flooded basement are finally over, and grateful they stand behind their work for a full year. Good contractors are hard to find. Glad I found them. Thanks and I highly recommend!"

"Chris was a clear, effective communicator, very professional, clear and transparent in his billing, and did a clean and effective job. Chris showed up on time, got the job done in the time he said, and made us comfortable and confident in his work. We had a really messed up (and ugly) radon system in our home; what we have now is aesthetically a huge improvement and mitigates radon significantly better. Highly recommended."

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.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

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.

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. 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 preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

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.
