Alexandria Radon Testing & Radon Inspection

Why Care About Radon?

Radon is a common cause of cancer. Radon is well known to lead to lung cancer in humans.

A large number of homes in the Alexandria area have a radon saturation at or above the actionable limit.

Radon gas comes from the topsoil, not the home. No home- new or old – is immune to radon gas intrusion.

Every property interacts with the ground beneath it differently. That is part of the reason why properties next door to others often have dramatically different radon gas accumulation.

Radon levels will rise or fall on different days and with the seasons inside of a normal range. A quick radon gas test measures a small period and is a good metric of whether or not the structure has radon contamination.

Radon gas has a dangerous duration of only days. radon accumulation won’t be any higher if the house is closed for months, days, or years.

How Does Radon Gas Filter into a dwelling?

It may surprise you to know that homes are not draft-proof.

Vapors will infiltrate through every grounded vent in the structure such as drains, plumbing, and minor gaps in the concrete slab or foundation.

The method to know with certainty the saturation of radon in the home is to have a radon test.

Our Radon Testing Procedure

Inspecting a house for radon is a unique process when completed as a part of a property sale.

A radon specialist will situate the radon gas analyzers on the property. Radon gas monitors are situated in crawl spaces and on the first floor. Normally between 1 and 3 monitors are located in the property for the radon gas testing.

Your radon gas specialist will seal every window and door, seal the vent on the fireplace, and make sure the heating and cooling system is running in the required manner. The radon expert will also treat every required window with tamper-proof tape to ensure that draft requirements are maintained.

The radon apparatus is stored in the house for several days to analyze the prevalence of radon gas in the property. A technician will revisit the house once the radon test is completed to remove the analyzers and generate a report.
