Best radon detection and reduction specialists near Concord, NH

"Airtight did a great job from start to finish. Pre-mitigation testing showed radon levels ranging from 3-12 pCi/L, with an average above EPA recommendations. Accurate estimate, explained every step along the way. The actual job was complete in less than a day! Radon levels taken through the pilot holes were through the roof (150 pCi/L for one hole, average of 118 for all pilot holes)! Now the levels average at 1.7 pCi/L over a three day period, with only a single data point hitting 3. I highly recommend Airtight Radon Solutions, LLC for radon mitigation!"

"Everything went very well from meeting to quote the job through to final certification. The crew was professional and took great care to cover all carpets going through the house to the attic."

"They were very helpful and had my replacement Radon fan installed in less than 1 week."

"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!"

"Dillon was amazing. Did what he told us. Fast a great worker. Bulkhead/basement stairs."

"The company was very easy to schedule with, and the technician was extremely friendly and efficient! I would definitely recommend them for radon mitigation systems!"

"I think the total cost was around $2,500. I think the technical it is good, the good side, the bad side I think is the process between my first phone call and the last work was long."

"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.
