Did you know that water can hide behind walls without you even really noticing? Here they had a leak that they thought was taken care of but what we didn't realize was that there was a secondary leak from the run off of the other leak that was virtually unnoticed. When they found it the wall was completely saturated from the inside. To the naked eye it looks fine. We have a tool that can show us infrared spots behind the wall along with a moisture detector that will allow us to know if the cool or hot spots are moisture.
