"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."

"Mark, the owner came over himself to estimate the job. He was extremely knowledgeable and was able to explain what and why they were going to do. He also was able to give comparisons of equipment used by other companies. The front office kept me updated on tests and appointments, timely. His crew was very professional and PUNCTUAL! They took the time to remove all signs and equipment of my old water system, which they didn't have to do. Due to hard-packed dirt under my basement floor, they had to return 3 times to bring my Radon Air within EPA standards. However, the quoted price didn't change, and each time the crew was as professional as their first visit. I highly recommend Mark and US Water Consultants for your Radon Air Mitigation and any water improvements and modifications."

"John was great, came to inspect our home in Rochester and was professional and had every piece of equipment you could need to give us a detailed look into our house. Even when the seller made a mistake on the sewer and water system types John helped us test both and went above and beyond. Cannot recommend enough if you want a the best and safest bet for an inspection!"

"They were the first to give us a quote and were able to come out as soon as we needed them to. Installation was smooth, and they have been good at following up to make sure the system is working. Because our radon is still slightly high, they are doing another radon test and will follow up if it comes back high yet again. We would definitely recommend them to others!"

"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 fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.

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

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.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

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