"OUTSTANDING WORK on short notice. The Radon Shield team did some very impressive work for us and we will certainly reach-out to them for other services in the future. For this project, we asked Mr. Ugorji and his team to install 2 separate radon mitigation systems for a large sq ft home with a basement air radon concentration well over 4 pCi/L where masonry drilling would be required for the installation. We also faced difficult time constraints, but Mr. Ugorji arranged to begin work the next day. Before visiting the work site, we discussed the installation, the home, expectations. He provided a clear and accurate assessment of the costs and time/effort required for our project (our final bill matched his initial assessment, nothing added, no surprises). The location for the installations, routing of piping and wiring, model fans to be used, attachment and sealing methods, follow-up testing, and much more were discussed before work began. Our preferences were addressed and pros/cons were weighed. Mr. Ugorji worked efficiently and his team tidied-up as the work progressed. All aspects of the installation were handled professionally. Care was taken to upgrade remote junction boxes and other components impacted by the new system. The routing of the suction/exhaust piping was thoughtfully designed, securely installed, and tightly sealed. When both systems were turned-on, they presented matching suction levels, indicating effective under-slab suction. The end result is a very effective radon mitigation system that has (after a few days of constant electronic monitoring) achieved a basement air concentration of 0.35 pCi/L. Mr. Ugorji followed-up with us a few days later to check on the new radon test levels and to ensure everything was as expected."

"Fantastic to work with. I received an elevated radon level after a recent test which required mediation. RAdata were very responsive and timely. They even called several days prior to my appointment to offer a new time after a cancellation. They arrived on time, quickly diagnosed the problem, and performed the required work. The technician took the time to fully explain the system and offer suggestions after a new issue was found. I would highly recommend their services."

"Dave spent an hour and a half on the outside alone. He left no stone unturned unless the seller had furniture or boxes in the way. He had been in the construction business for 30 years, and that was very apparent. He found things I would have never thought of, and was honest when he found good things as well. He spent the time to explain and remind me of even the simplest safety things you should do in a home, like hitting the test and reset buttons on outlets once a month. Apparently they break after a while and don't work at all. I would definitely recommend Dave!!

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.
