"Tom and April are indispensable if you are buying a home. Tom and April have inspected multiple homes for me, and their expertise is as good as it gets. As a first time home buyer, I did not know what to look for in some of the older homes in southeastern Connecticut, but Tom was able to explain everything clearly and concisely. He is a very thorough home inspector, and will methodically go through each room, outside of the house, and the basement to show any signs of wear or issues. If you use Sound Home Inspections, you can be sure that because of Tom's years in the field, and knowledge from flipping houses no stone will be unturned! He is an invaluable resource for any home buyer, and as I said, I have use him multiple times because I know that he will be honest and knowledge about about all aspects of a home inspection."

Radon Detection and Reduction questions, answered by experts

Costs for radon detection services typically range from $150 to $250, depending on the testing method and whether a professional assessment is required.

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.

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

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.

No level of radon is technically safe, but because it’s everywhere—even in the air outside—it’s impossible to avoid entirely. Instead, the Environmental Protection Agency encourages taking preventative measures if the levels of radon in your home rise above 2 pCi/L. (For reference, the average radon level in homes across the United States is 1.3 pCi/L.
