Many vapor intrusion mitigation techniques are based on the same principles used in radon mitigation. The goal is not necessarily to remove the original source of contamination, but to redirect the pathway between subsurface vapors and indoor spaces.
Arizona continues to see commercial and multifamily construction, especially across the Phoenix and Tucson metro areas, even though growth has slowed somewhat in recent years. One area that is often overlooked—but easy to address during new construction—is radon testing and mitigation.
The FHFA has rescinded its 2023 directive that required standardized radon testing for all Enterprise-backed multifamily properties, allowing Fannie Mae and Freddie Mac to set their own, less rigid policies. While national testing mandates have been lifted, builders and contractors are still encouraged to incorporate radon-resistant construction methods early to reduce long-term risk and ensure compliance with HUD and local regulations.
When it comes to the safety of your home or business, few features are as critical as a reliable radon mitigation system. However, the amount of suction required for optimal mitigation can vary depending on a number of factors such as design and size. To help determine the proper level of suction and measure the effectiveness of a mitigation system, we perform what is known as Pressure Field Extension testing.
While radon concerns often center around residential homes, commercial properties across the Southwest must also contend with this invisible radioactive gas accumulating in workplaces.
