"Competitive pricing; high quality work; timely service, friendly service, and outstanding warranty all describe this work done by Professional Inspection Service. They came back multiple times until all aspects of the radon mitigation were done to my satisfaction. Recent radon readings average below 1.0, well below the recommended 2 pCi/L. I could not be happier with the work they did."

"It went fantastic. Scheduling wise the gentlemen at Rhino Radon were quick to respond to our inquiry via there website were I filled out a online questionnaire. Once speaking to Henry about the specifics of my home via phone and letting him no my situation. They were prompt in scheduling a date for installation to assure my radon problem didn't delay my ability to sell the home. From the time I filled out there questionnaire on there website till the system was installed and fully operational, all took place In one weeks time. I no from experience that these days the attentiveness and service Rhino Radon provided me can be difficult to find. Having recently just finished the process of building my own home in Malden and dealing with a wide range of company's and workers. It's the little things that stand out like personal treatment,responding quick to inquiries or concerns and of course taking the time to do things properly the first time around while still treating the home with respect. Rhino Radon came recommended to me via a friend and I couldn't thank them enough for steering me in the right direction for my radon mitigation needs. I would like to do the same to anyone currently searching for a radon company. If you want the job done right and a pleasant experience, look no further for your radon needs then Rhino Radon Services.

Radon Detection and Reduction FAQs, answered by experts

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.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.
