"Frank was extremely thorough and allowed us to follow him throughout the home inspection. He stopped to explain his findings to us and gave us recommendations for fixes. His report was very detailed and we received it the following evening, including photos. I would highly recommend Frank, as he was very knowledgeable and gave us the peace of mind to continue on with the home purchase!"

"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

"Dennis and Brian from BioClean couldn't have been any more professional, or honest! They were able to schedule a same-day appointment, and were exactly on time. Within minutes of entering the home, they measured for airborne particulates, and indicated that the levels were not very high at all. They proceeded throughout the home, entered the attic and inspected the air handler, and concluded that everything looked fine - even in the areas we would never have thought to check. What they did discover was that there is some moisture in the basement that may be coming from a leaky toilet. We never had any idea! With the free inspection coupon (found here on Angie's list), they did not make any money at all - but less honest people could have told us anything and we probably would have believed it, and paid through the nose. It's companies like this that remind me that there are good people out there! Thank you, BioClean! Should we need your services after the toilet repair, we will DEFINITELY call you."

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.
