Ashburn Radon Testing & Radon Inspection

Why Care About Radon Gas?

Radon is a common cause of cancer. It is proven to cause lung cancer in children and adults.

38%+ of houses in the Ashburn area have a radon gas concentration near or above the dangerous amount.

Radon gas seeps out of the topsoil, not the building. No property- new or old – is exempt from radon gas infiltration.

Each and every home interacts with the ground beneath it differently. This is part of the reason why properties adjoining one another have dramatically different radon gas levels.

Radon accumulation will shift on different days and seasonally inside of a reasonable range. A quick radon gas measurement measures a single day or week and is an accurate metric of whether or not the structure has a radon gas problem.

Radon gas has a half-life of 3.8 days. As such, radon levels will not be greater if the structure is enclosed for months or years.

How Does Radon Enter the Dwelling?

Houses are not supposed to be entirely airtight.

Gaseous contaminants can enter through each ground-facing gap in the structure such as sump pumps, pipes, and even minor cracks in the foundation.

Your method to know confidently the saturation of radon gas in the abode is to have a radon test.

Your Radon Test Steps

Probing a home for radon gas is a special procedure when completed as a part of a real estate purchase.

A radon specialist will install the radon probes in the house. Radon gas probes are dropped off in crawl spaces, the level above crawl spaces, and any room touching the earth. It is typical that a few monitors are installed in the structure for the radon testing.

The radon gas expert will close windows, shut the damper on the fireplace, and make certain the heating and cooling system is functioning in the required manner. Your radon gas professional will additionally seal all required windows with tamper-proof tape to confirm that draft conditions are upheld.

The radon apparatus remains in the building for two or three days analyzing the amount of radon gas in the property. A technician will revisit the property after the radon test is finished to return the probes and generate a report.
