"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!"

"Radon 1 did a great job. We wanted to have our existing radon mitigation system removed as it was right by our new screened in porch and have a new one installed in different location in our home. The crew removed the old system and installed the new system in an area far from our screened in porch. The installation was done in an expert manner, the crew were respectful of our property, quiet, clean, wore masks and cleaned up after themselves so you would never know they'd been there, all in less than a day. The pricing was competitive, we feel like we got a fair price. I would hire Radon 1 again."

"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."

"With the recent snow melt and the rain we are having this may be a timely recommendation. I hope you don’t have this need, but if you do I would like to recommend Master Service Company. We had at least six estimates for waterproofing our basement and although not nearly the cheapest, we were impressed by the presentation and the personnel and low key sales approach. So, we hired them! The work was done last week and again we were impressed with the crew doing the work, the care given to hold down the dust created, the quality of the materials used, and the willingness of the crew to keep us apprised of the job as it progressed. The was great care given to cleanup of what is a very messy job. We waited until the repair had been “battle tested”, (and this inclement weather has certainly accomplished that) before writing a recommendation. We could not be more pleased at this point. Again I hope you don’t have the need, but if you do give Mr. Jeff Russell at Master Service a call. Contact: Jeff Russell 317-720-3288."

Radon Detection and Reduction questions, answered by experts

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.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

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.

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