Tysons Radon Testing & Radon Inspection

Why Care About Radon?

Radon is a dangerous cancer-causing chemical. It is well known to cause lung cancer in children and adults.

38%+ of houses in the Tysons area have a radon gas saturation near or above the actionable amount.

Radon gas filters out of the soil, not the home. No home, new or old, is exempt from radon gas infiltration.

Every house interacts with the ground differently. This is part of the reason why houses adjoining one another often have radically different radon gas accumulation.

Radon gas saturation will change on different days and monthly inside of a normal range. A short-term radon test measures a single day or week and a solid bellwether of whether or not the land has a radon gas issue.

Radon gas has a half-life of only days. This means that radon concentration will not be worse if the property is sealed for days, months, or years.

How Does Radon Gas Enter the Home?

Houses are not supposed to be completely draft-proof.

Gaseous contaminants may infiltrate through each ground-facing gap in the home such as drainage, plumbing, and slight gaps in the foundation’s concrete.

The method to know with confidence the saturation of radon gas in the abode is to order a radon test.

Your Radon Test Procedure

Sampling a home for radon gas is an important process when delivered with a house purchase.

A radon professional will install the radon gas probes in the house. Radon analyzers are installed in crawl spaces, the level above crawl spaces, and any room touching the earth. On average multiple monitors are left in the property for the radon analysis.

Our radon gas specialist will close every window and door, seal the vent on the chimney, and ensure the heater or AC is running in the prescribed manner. Our radon gas professional will additionally treat any necessary window with anti-tampering tape to confirm that closed-house standards are maintained.

The radon probes remain in the property for several days to measure the prevalence of radon gas in the building. A specialist will revisit the property once the radon test is complete to remove the probes and create a report.

Please call today for a no-pressure pricing estimate! Our radon testing staff will come to visit to learn more about your property, measure the area, and get you going on making your Tysons home one you can enjoy completely!
