Why RRNC Construction?
  • Code Compliant
  • HUD Compliant: Design and installation by an EPA certified radon professional is required by HUD
  • Reduced Liability: Most architects, general contractors, and developers’ liability insurance does not cover radon design or installation
  • Cost Effective and Energy Efficient: Properly designed and installed RRNC systems can work passively, eliminating the long-term energy costs of a fan-driven "active" system
  • Real Estate: Comfort knowing a new home is EPA/RRNC Certified and the work performed and guaranteed by a proven industry leader
  • Eliminates post-construction retrofit systems 

Proven Record
Every RRNC system we have designed and installed over the past 25 years has worked passively, effectively keeping average, long-term radon levels below 2.0 pCi/L without the need for an active, continuously running electric exhaust fan.
Do it Right the First Time
There is a significant difference between designing and installing an RRNC system per the minimum code requirements, and installing a system that actually works (per EPA standards).
