"Mark Rogerson personally came out to the house to test for radon. He is extremely personable and is incredibly knowledgeable. He is a ‘no-pressure’ guy and made us feel very comfortable. He was on time and always kept me informed as to when he would be at our house. I highly recommend Rogerson Enterprises LLC if you have any worries about radon in your house."

"Frank was great from the very start! We went with him to begin with because we had a good feeling after talking to him about getting a quote, and we are glad that we did. I would highly recommend him. He was very knowledgeable and thorough. We received our report quick and understood everything because he took the time and went through everything with us as he was doing his inspection. He answered all of our questions and had recommendations on what should be done."

"From beginning to end the project couldn’t have gone any better. In deterring the scope of the project, they listened to all our concerns, and devised a comprehensive plan to meet all our needs, not just simply an insulation replacement. The actual work crew was very friendly and respectful of our house and property. We alway got notice when they would arrive and were always on time. They kept us informed every step of the way with pictures of their progress. They let us know early on of one potential electrical issue with recessed lighting and worked closely with our electrician a couple days later to resolve the issue prior to actual blowing in of the insulation. Overall, a first class operation all the way and we already feel the benefits."

"We recently had a radon system installed. Thomas was easy to work with, reliable and seemed deeply knowledgeable about radon and radon systems. The process went as described and the basement radon reading decreased in the first few days and has stayed reduced. We had the system installed over a month ago, but I wanted to be sure to give a review."

"I have worked with many contractors,plumbers,electricians, etc. in my time owning two homes. On here in New England and the other in Pembroke Pines,FL. These gentlemen from rhino radon services were deffinelty personable and proffesional I felt like my home was in good hands with this company. After calling around and having a job scheduled with another mitigation company I was blown off and left with a short deadline. Luckily after speaking with Henri from rhino radon they were able to squeeze me right in your schedule the very next day even though they had two other jobs scheduled they showed up at 5pm and still completed the job to ensure I met my closing date, if your looking for a standout and accommodating radon company I would say look no farther then rhino radon. I was very pleased with the service I recieved. HIGHLY RECOMMENDED

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.
