HUD Multifamily Radon Mitigation Services in Greater Portland

Designing effective radon reduction systems for multifamily buildings

Since 2005, TerraFirma has increased the safety and value of multifamily homes throughout Oregon and Washington. If you are applying for funding through the U.S. Department of Housing and Urban Development (HUD) for the purchase or refinancing of a multifamily property, you are required to include proof of radon testing and mitigation if elevated levels of radon gas are found.

If you have had your property tested and your radon level is 4 picocuries per liter (pCi/L) or higher, TerraFirma can install a radon reduction system to reduce radon levels in accordance with American Society for Testing and Materials (ASTM) standards and the HUD Radon Policy.

Call TerraFirma today to schedule your radon consultation. We offer radon testing and mitigation services for all multifamily dwellings, including condos, townhouses, and apartment buildings in Seattle, Eugene, Bend, Medford and surrounding areas.

HUD policy requires radon testing in multi-family properties.

Installing radon reduction systems in large buildings requires extensive knowledge of building codes and construction designs. Things like HVAC systems, stairwells, elevator shafts, and complex foundations must be considered. The most common radon mitigation system is Active Soil Depressurization, but we will work with you to determine the best radon reduction method for your property.

With experience designing radon mitigation systems for multi-unit buildings, you can count on TerraFirma for effective reduction of radon levels and peace of mind. Once mitigation is completed, we will provide you with a certificate of completion and ensure that follow-up testing is completed.
