How do I get rid of Radon problems in my home?

The good news is that reducing radon levels in your home is a fairly straightforward process using what we call an Active Soil Depressurization (ASD) system. Effectively these systems work by creating a ‘vacuum’ or ‘negative pressure’ below your home by using a small fan that will then be routed and vented outside and away from your home. The three most common ASD systems we use are:

Radon Mitigation Systems

Sub Slab Depressurization Diagram

Sub Slab Depressurization

If there is no exposed crawl space, drain tile, or sump pump system, a suction point is created through the concrete slab and a small pit is dug under the slab. A vent pipe connected to a small fan is then routed from the suction point through or outside the home where radon gas can be released away from the home.

Sub Membrane Depressurization Diagram

Sub Membrane Depressurization

If there is an exposed crawl space, a membrane is installed and sealed to the foundation walls creating an air-tight seal over the exposed ground. A suction point is then created through the membrane where a vent pipe connected to a small fan is then routed from the suction point through or outside the home where radon gas can be released away from the home.

Drain Tile Depressurization Diagram

Drain Tile Depressurization

If there is an existing drain tile or sump pump system, a suction point is created in or next to the drain tile that extends under the slab of the home. A vent pipe connected to a small fan is then routed from the suction point through or outside the home where radon gas can be released away from the home.

About Radon:

Radon is a naturally occurring gas that is both odorless and tasteless and is produced in the soil as uranium breaks down over time. It is the leading cause of lung cancer in non-smokers and the second leading cause of lung cancer overall resulting in almost 21,000 deaths each year.

As uranium in soil, rock, and water breaks down over time, it natural releases radon gas as a byproduct. As this gas is released in the soil, small amounts seep into your home through cracks in your foundation walls, basement slab, or exposed crawl space. Over time this gas makes its way into your homes living space.

The only way to know if you have an elevated level of radon in your home is to test. Just because your neighbor has a low or high level of radon in their home doesn’t always mean your house will be the same.

No level of radon is considered safe, however the EPA has established a National Action Level set at 4 pCi/L (Four pico curies per liter of air).

Yes they can! There are a lot of different factors that can cause radon levels to fluctuate in your home including seasonal changes, different weather events, and even the construction style of your home.

Radon exposure over time can lead to an increased risk of developing lung cancer. As radon gas inside your home breaks down it emits small particles called alpha particles. When inhaled, these particles get trapped in your lungs damaging your lung tissue which increases the risk of developing lunch cancer.
