Radon Resistant New Construction
Finding a Builder Who Uses Radon-Resistant Techniques
All homes and additions to existing homes in unincorporated Linn County must be built using radon-resistant techniques. For many, finding a builder can be difficult, but finding one who uses radon-resistant techniques can be easy. Once you have chosen your builder, use this EPA checklist to be sure that Radon-Resistant features have been installed in your home.
Radon-Resistant New Construction
When new homes are built, they can be constructed with radon resistant features. Adding these features during the construction process is much less expensive than adding radon-resistant features later on. According to the United States Environmental Protection Agency, the cost of Radon Resistant New Construction is usually between $250 and $750. The cost could be less than $250 if the builder already uses some of the same techniques used for moisture control. The cost of installing a radon mitigation system post construction is between $1200 and $2000.
Homeowners who have radon resistant features in their house should still test their home for radon every 2 years. Test kits can be purchased at Linn County Public Health or at local hardware stores.

How do I know if my fan is working?
If you have an active radon system typically you will have what is called a U-tube manometer that measures fan operation. The level of liquid in the manometer should not be at an equal level on both sides. If the level is uneven, this means that the fan is operating correctly.
