As of April 2011 the State of Oregon adopted senate bill 1025 establishing minimum requirements for radon resistant new construction.  The state of Washington adopted similar radon system requirements years prior.

New residential and multi family structures must now have a minimum passive radon mitigation system according to EPA radon mitigation standards. These design standards are found in Appendix F of the Oregon Residential Specialty Code. The standards were adopted and implemented due to the risks associated with radon gas exposure in buildings and the simplicity and effectiveness of these systems when designed into the rough structure of the building. New construction systems often outperform retrofit systems for a lower installed cost, when installed correctly.

Environmental works has partnered with residential and commercial building and remolding companies to provide fast, high quality and affordable new construction radon mitigation systems, backed by a fully transferable 10 year guarantee that it will passively work.  If it needs a fan to bring levels down, then we will install it for FREE!

Our expertly designed passive radon systems are fully code complain and often solve the radon issue completely without any further mitigation procedures being necessary. The passive system can easily be made active if post build testing is above 4.0 pCi/L by simply adding a continuous radon fan.

Don’t Trust just anyone to install your radon mitigation system. You can rely on Environmental Works to provide you and your customers with the highest quality radon mitigation system, fast and professional service, and long term peace of mind.
