Holladay Installation

Beginning radon level: 103 / Ending radon level: 2.7

We bid and installed two radon mitigation systems to get the levels to under 2.7. The initial test came back as 12.2 in bedroom below kitchen and 103 in the back bedroom.  We installed a west elevation and there was a normal framing wall upon the stone we placed. We put a system in the west side of the house and this got the level When we installed a second system and had to include a concrete retain wall, we got the bedroom under the kitchen to 0.8.
