"H&G is fantastic - extremely professional, timely, and by far the best bang for your buck. I was able to talk directly to the owner and easily schedule an emergency appointment for that same day. Mr. Garvin himself came out the the property to locate and treat standing water and mold in our crawl space and kitchen and conduct an air quality test. He worked hard and quickly to identify and fix the issue, didnâ t overcharge for anything unneeded, and even took the time to be sure we understood exactly what he was doing. Overall I appreciated their urgency, care and precision. Iâ ll be using H&G from now on!"

Radon Detection and Reduction questions, answered by experts

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.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

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.

The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L).
