"Marcel performed a flawless installation of a Radon Mitigation system in my home. He thoroughly explained and shared testing results as he proceeded with the installation. He continually checked and rechecked his measurements and cuts making sure everything was level and plumb. I'm a very meticulous customer and I was completely satisfied with my new system. He left an instrument to monitor my radon levels for a few days just to be absolutely sure that everything is performing as it should be. If you need Radon Mitigation...I HIGHLY recommend Airtight Radon Solutions."

"I hired Erickson for a radon system. All the pros in my area charged about the same price for one. Erickson differed because of the knowledge they shared and they are also one of the few places that have a 10 year warranty. I paid a little more for the 10 year warranty system and I am glad I do not have to worry about one thing in my house for a while now. The team came in and installed my system in just under 3 hours. They were professional and respectful. All in all, I think I made the right decision choosing Erickson."

"Radon Systems LLC did a great job. I had a radon level of around 6.5 in my basement for years, and finally decided I needed to address it. After receiving 3 quotes, I had Dave from Radon Systems come over to do the job. I initially was resigned to having the PVC pipe go up the side of my house, but Dave found a way to run the piping inside the basement and go thru the garage, with only 18" of PVC sticking up past the garage roof. Excellent! And now my radon level is around 1.0 to 1.5 all the time. The entire job took half a day, and Dave was clean, respectful and easy to work with. I absolutely recommend them."

"George and his team did an excellent job with the install. I received quotes that were much higher for the same project and similar systems. As busy as George was he always answered my questions leading up to the install and was there right when he said he would be. George even helped me plumb a water line to my refrigerator and didn't charge me for the material he used! I have already recommended Absolute Water Systems to a friend and will certainly be using them for any future projects."

"He was on time, arrived at 9am as quoted and began to install the system. The system required two suction points and a sump pit cover. The sump pit originally had a pedestal pump in place and none of the other radon companies would change the pedestal pump to a submersible pump as required for the mitigation system to function properly. Rhino Radon not only changed the pump but installed a back flow check valve to ensure proper functioning of the system. All of the other companies said we would have to employ a plumber or a handy man to get this done. Had we gone that route the closing would not have happened. Rhino Radon gladly did all the work required and didn't even break for lunch!!! He was more concerned with getting us out of the vacant house seeing we are already down the cape. The system that involved a crawl space and being vented through the garage roof was completed immaculately and the test results came back at 0.5 pCil/L. This pleased the lender and buyer and exceeded our expectations. We highly recommend Rhino Radon Services.

Radon Detection and Reduction questions, answered by experts

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

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

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

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.
