Buying a new home is probably the biggest investment you'll ever make. It's a decision that will affect you for years to come. There's always considerable risk involved when making such a large purchase decision, a professional home inspection done by Yankee Home Inspection will significantly reduce your risk and help make the entire home buying process easier and less stressful. I believe that the buyer, seller, or agent are honest. As an independent home inspector, I will take the time to do a complete home inspection.

"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

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

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.
