Herndon VA Radon Testing & Radon Inspection

Radon is a Class A cancer-causing agent. Radon is well known to lead to lung cancer in people.

38%+ of homes in the Herndon VA area have a radon concentration at or above the actionable limit.

Radon comes from the soil, not the building. No structure, newly built or longstanding, is fully shielded from radon gas.

Each house interacts with the ground beneath it uniquely. That is part of the reason why properties adjoining one another have majorly different radon saturation.

Radon gas concentration will change every day and monthly inside of a normal range. One-time radon measurement is a snapshot and a reliable metric of if the structure has a radon saturation.

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

How Does Radon Gas Enter the home?

Surprisingly, homes are not completely hermetically sealed.

Gas may seep in through each ground-facing gap in the building such as drains, plumbing pipes, and even small imperfections in the concrete slab or foundation.

Your method to know with confidence the concentration of radon gas in the structure is to contract a radon test.

Our Radon Test Steps

Probing a house for radon gas is a special procedure when doing a property purchase.

Your radon gas specialist will position the radon gas detectors in the dwelling. Radon analyzers are situated on any level that touches the ground. Typically multiple monitors are left on the property for the radon measurement.

The radon professional will seal windows, close the damper on the chimney, and confirm the HVAC system is running in the prescribed manner. Our radon specialist will also seal any necessary window with tamper-proof tape to make sure that closed home requirements are maintained.

The radon probes stay in the home for 2-3 days to analyze the amount of radon gas in the structure. A professional will come back to the house after the radon measurement is complete to take the analyzers and create a report.
