Radon Detection and Reduction questions, answered by experts

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

What is radon? It’s a radioactive gas that naturally occurs in the ground, forming as uranium and thorium decay. It has no color or odor, so you don’t know if it’s seeping into your building’s foundation. Regular exposure to radon gas increases your chances of suffering from lung cancer. Radon testing measures the air inside your house for the presence of radon gas. If detected, the test will measure the severity of radon levels in your home’s air.

Radon is a colorless, odorless gas that can cause lung cancer; testing ensures safe indoor air quality.

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

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.
