"Radon Consultants gave a very competitive bid for the work, so we hired them. The work was done as promised, when promised, and with excellent results. They took an incremental approach, which would have saved money. Our problem was about 70% solved by that approach. By adding additional capability to our radon mitigation sysrem, the remainder of the ptoblem was taken care of at a very reasonable price. Their total price was about the same as a competitorâ s price for the first phase."

"Avert Radon LLC , specifically Chance, recently completed radon mitigation work at my residence, installing two systems. I typically refrain from writing reviews, but felt compelled to share my experience with Avert Radon LLC . I'm extremely satisfied with the results, as the radon levels are now virtually undetectable. Chance demonstrated exceptional professionalism throughout the process. The communication was excellent, and their meticulous attention to detail was also outstanding. Furthermore, their post-installation follow-up has been consistently excellent. I highly recommend this company without reservation. They are among the best service providers I've encountered. if I could give it more than five stars, I certainly would!"

"I am a homebuyer. I contacted the Inspector (Pat) through Angies list asking if he could provide me several days and times he would be available for doing a home inspection, and also for pricing. He was prompt in replying, provided both pieces of information requested, and also noted that he could do Radon inspections at a good price. His response to me was very professional and made a good impression on me."

"Overall, we were very satisfied with the knowledge and quality of work that Covenant LLC provided. We had Covenant LLC install a radon mitigation system for our basement. Initially my husband and I met with David for the estimate and consultation. David spent the time to explain how radon can get into the basement, what the system would look like, and how he was going to make sure it was working. After meeting with David at Covenant, we met with a competitor who were definitely not as knowledgeable, were not going to seal any of the cracks or holes in the foundation or even follow industry standard by venting through the roof of the house. The day of install the crew was personable and professional and if they had any questions, they asked. The 3" pipe that Covenant had to install to run through a closet and into the attic. In order to do this, they had to drill through the porcelain title floors and run through 3 shelves. They spent extra time to jig-saw cut the shelves around the pipes and they took special care not to crack any of the porcelain tiles and when finished it looked like it was built with the house. After completion, Covenant came back and tested the radon levels which were reduced to below their guarantee, which itself is orders of magnitude below the EPA limit. We were probably not the easiest clients to work with as we had Covenant move the roof penetration several times until the noise was completely unnoticeable. David was always polite and professional and he wouldn't be satisfied with the job until we were satisfied. We highly recommend Covenant Air to anyone who is considering these services."

Radon Detection and Reduction questions, answered by experts

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

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.

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.

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.

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.
