"I called John on a Thursday night looking for a 9AM, next day inspection of a property on auction that I needed inspected before I put my bid in. He answered my call, texted me, planned everything and was there at 9am ready to work. He gave us his immediate thoughts so that we could make an offer with good info and then sent us a super detailed report. I couldn't recommend him more. He gave us great peace of mind."

"The house we found and wanted to buy was built at the end of the 18th century. While the house kept many its original features it looked like it was well maintained by the owners. However, with the house of such age no one can be sure that there are no serious problems hidden somewhere. Since we have not been that lucky with the inspectors in our previous house buying we were very thorough and not in a hurry looking for an inspector. We wanted to find the “best of the best”. Our Realtor who was very helpful during the whole buying process recommended us a couple of inspectors. Also we found a number of inspectors with very good reviews on the internet. We communicated with those inspectors and explained our situation about historic house. What surprised us is that they promise to conduct the whole inspections of the house together with inspecting septic system just within two-three hours. Yes, they were going to get help from one of their team members, but two-three hours for the house built in 1790 was certainly not enough. So, we continued our search. One by one we were scanning through every review on the Internet on home inspectors we could find. At some point we stumbled at the review where the buyer was upset that the inspector he hired spent too much time conducting the inspection. That inspector was Mr. Stephen DeCosta. We called him to discuss our case. He sounded solid, explained us the process in details, and informed that the time he spends on the house like ours is not less than 4-5 hours. In addition, he recommended us septic system professional. Looking ahead – we were very happy with the work of that septic system guy. Steve is very thorough, knowledgeable, and highly professional inspector. He totally spent 6 hours conducting house inspection. While inspecting the house Steve explained every small detail even suggesting how to fix the problem. I am an engineer myself. I can do almost any job with my hands and skills - from house repair to house remodeling. However, I was impressed with the depth of Steve's professionalism. At the end of his inspection Steve provided us with a detailed report of all things that need to be fixed. Steve’s report helped us to create a good list of all problems in the house and to re-negotiate a better price for the house. He is the best home inspector we ever worked with. All together working with Steve was a fun, a good learning lesson, and a very reassuring process. After his inspection we knew for sure that we made a good choice, and while the house is old we got confidence that we will be able to fix all the problems the house has. We highly recommend Steve to every one who is looking for a great professional and expects a consistent result of home inspection."

"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

FAQs for radon gas testing projects in Plymouth, NH

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
