"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!"

"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."

If radon is present in your home, you can expect to pay around $1,000 for a radon mitigation system or between $780 and $1,250 in most cases. The exact price will depend on the severity of the radon leak, home size, and the protocol the radon specialist develops to remove radon from your home and keep it out. Your foundation type will also affect your radon mitigation system cost, as unfinished basements will cost about $4,600 to seal and ventilate, while crawl spaces without a foundation slab may need extra encapsulation, costing $1,500 to $15,000.
You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional.
Radon testing costs depend on whether you hire a professional radon inspector or DIY test. You can expect to pay $150 to $800 to hire a local radon inspector, and home-testing kits range in price from $15 to $250 from home improvement stores. However, it’s best to trust a professional inspector with this task to ensure accurate results. Plus, if you have radon in your home, your testing company can develop a mitigation protocol to keep you and your family safe from the dangerous gas, so it’s well worth the money to hire a professional.
Yes, radon testing is absolutely necessary if you suspect the presence of this hazardous gas, and the Environmental Protection Agency (EPA) recommends testing for all homes in the country. Radon is a pervasive natural gas that can leak through your home’s foundation and seep into the living areas. Unfortunately, the gas is highly carcinogenic and is the second leading cause of lung cancer. Radon testing is crucial for keeping you and your family safe from harm, so hire a radon mitigation specialist to test your home if you suspect its presence in your home.
In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.
