"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."

"Radon Shield did a wonderful job with radon remediation in our basement - our level was below 4.0 but we wanted it even lower. Benedict and his team worked efficiently and carefully, and our radon level is now 0.3 upon repeat testing after fan installation. They are professional and reliable - highly recommend their services."

"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."

Radon Detection and Reduction questions, answered by experts

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.
