Fairfax Radon Testing & Radon Inspection

What to Know About Radon Gas?

Radon is a common-place cancer-causing agent. Radon is proven to lead to lung cancer in humans.

Many homes in the Fairfax area have a radon gas saturation higher than the dangerous amount.

Radon gas seeps out of the soil, not the house. No home, newly built or longstanding, is immune to radon infiltration.

Each property interfaces with the soil differently. That is part of why homes adjoining others can have significantly different radon gas levels.

Radon gas accumulation will change daily and seasonally inside an acceptable range. A short-term radon gas test measures a single day or week and accurately indicates whether the structure has a radon gas issue.

Radon has a half-life of about half of a week. radon gas accumulation won’t be greater if the structure is sealed for days, months, or years.

How Does Radon Gas Seep into your house?

Houses are not supposed to be sealed.

Gaseous contaminants may infiltrate through every penetration in the home such as drainage, utility connections, and even small cracks in the concrete foundation.

Your way to know with certainty the concentration of radon gas in the dwelling is to run a radon test.

Our Radon Test Procedure

Sampling a property for radon is a special process when completed concurrently with a property sale.

Our radon technician will place the radon gas analyzers in the house. Radon monitors will be installed in crawl spaces and on the first floor. On average a few monitors are installed in the house for the radon analysis.

Our radon gas expert will close every window and door, close the damper on the chimney, and ensure the heater or AC is functioning in the required manner. The radon specialist will also mark every necessary window with anti-tampering tape to confirm that closed home requirements are maintained.

The radon apparatus remains in the home for several days to record the levels of radon gas in the building. A technician will revisit the home once the radon measurement is complete to return the monitors and generate a report.
