Radon Mitigation is any process used to reduce radon gas concentrations in the breathing zones of occupied buildings, or radon from water supplies.  How is it determined whether or not you need radon removed from your home?  According to the EPA's standards, any house or structure that has levels higher than 4 pCi/L, needs to have a system installed to reduce indoor radon levels.  If a system is installed and operates correctly, you can get to very low levels.

Generally speaking there are two different types of options that are used to reduce the indoor radon gas levels in a home.  Installing a system, mainly its components, must meet local building codes, i.e., electrical outlet box, wall or roof penetrations.  In some areas, a  permit from cities must be obtained prior to any installation.  Obtaining a permit will increase time and expense of the job.

This is typically the most common used method in radon mitigation.  This radon control technique utilizes a powered fan to achieve lower air pressure in the soil underneath the concrete slab.  The fan creates a negative air pressure under the slab and vents the air above the roof.  All cracks and gaps are also sealed through out the basement.

In this technique, a soil-gas retarding membrane is laid over the crawlspace floor, and a vent pipe with a powered fan creates negative pressure that pulls the air beneath the membrane and exhausts above the roof.

This technique also utilizes a fan-powered vent that creates a negative pressure within the crawlspace and draws the air out and exhausts it above the roof.
