About 9 months ago we tested for radon in our new house and the level was 5 pCi/L. The FDA says anything over 4.0 should be mitigated, and the WHO says anything over 2.7 should be mitigated due to the cancer risk from radon exposure. We called AZ Foundation Solutions and their engineers reviewed our floor plans designed a mitigation system which they installed. We waited about 9 months for the system to do its job and then retested. We were very happy to see the results. In the two rooms we tested, one was 0.7 and the other was 1.0, well below acceptable levels. The AZ Foundation Solutions system really works! We had one communication problem but the company addressed it.
Wonderful staff and great crew!
