"This was a great experience from start to finish. They arrived on time got and got the work done with zero mess even though this involves drilling a large hole in the basement floor. The system did what it’s supposed to do and reduced radon levels to almost 0. I am very happy with this company and would highly recommended them.The price was great too."

"MaGen did an amazing job testing and abating our radon issue, which we weren't even aware of. Maryan's process was easy to follow, he performed work that was even beyond the agreed process (like making necessary fixes to our crawl space), and ensured that the radon system was working well. We went from having the meter read over 10 (pre-work) to under 1. If you're looking for someone that can handle your radon needs, get MaGen to do it ASAP!"

"To the folks at Radon Be Gone and potential customers, Lengthy-but hopefully insightful Recently I learned that radon was present in my house and the intelligent thing to do is to have it mitigated. This occurred at the onset of the pandemic and the Governor's briefings and closures. I had read plenty of positive reviews about Radon Be Gone and they came personally recommended from a couple people I trust. At the time Radon Be Gone was not operating until they felt they had a great grasp of safety protocols for their staff and customers. I did have a few other companies come out, take a look, and provide a quote but my gut told me to wait if possible for Radon Be Gone to be operational. I spoke to Portia several times and she was very knowledgeable, reassuring, and answered a lot of questions I had, now that I had some time to learn about the gas itself and how companies mitigate it. Brad came out and did an honest assessment and again answered a host of questions. Due to previous reviews, their treatment of me, and the similar price to other companies, I chose Radon Be Gone. I was a bit nervous because I had finished the basement a couple years prior. For anyone that plans to finish their basement, check for Radon first. You have less options once you finish it. The day the job was to be completed, the vehicles were in my drive a few minutes early, which I liked. The guys: Larry, Walker and Ian were all very cooperative and professional. I was able to watch and learn without feeling like I was snooping. The holes in my side brick and facial wall and the foundation were precision. We couldn't have picked a better spot for the system. It is unobtrusive in the utility room and is not visible from the sides of the house that matter. They explained the system and how it works and some small other need to know items. They caulked all the exterior hardware and sealed and cleaned everything. For those of you that may be concerned about their Covid safety protocols- I was very comfortable with how they operated. Post installation of the equipment, they retested the Radon Levels in my house and I was not only under the accepted level, but significantly under. The report of the test and other details were provided in a very timely manner. As a matter of fact the gentleman, forgot his name, (sorry) text me the results immediately. I know this is probably a lengthy post, but hope it provides useful insight and my recommendation of using Radon Be Gone if you need to have Radon Mitigation."

"Absolutely professional. Tyler came out exactly on time. His co worker/partner set everything up and explained the process and worked with our schedule. Pricing was VERY affordable and for a job done exceptionally well and clean. I reccomend getting the levels tested in your basement as over time this can be detrimental to ones health. If we have any issues in the future, I will be using Ohio Radon Specialists for all of our mitigation needs."

Radon Detection and Reduction FAQs

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.
