"Jon at Finest Home Inspection was great. He walked us through the inspection and his findings on site as well as answered our specific questions about the house. Our inspection report was provided the same day and the radon test results were provided as soon as they were available. He let us know what he wasn't able to check because there were tenants living in the house. He gave us his honest opinion on the house when we asked him. It can be difficult to assess the thoroughness of a home inspection, but now that we've been living in our home for a while, I am confident our home inspection was thorough. We haven't run into any issues that were not addressed in the home inspection. I would recommend Finest Home Inspection."

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.

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.
