I have a client that is getting water coming in at the tile floors and wall intersection on the inside of their home when it rains. This is a newly built home (2007-2008). This appears to be happening below the windows. There is baseboard tile installed, which is starting to move out away from the wall, but at the top grout line my moisture meter pegs, as I move up the interior wall the moisture meter drops back down. The windows are a Built Best brand, model # BIB-N-003 series ECLD/CSMT/AWN/VT. They are a casement type window. I am trying to help figure out were the water is coming from. Anyone had any experience with figuring something like this out?
The landscaping on the exterior does not seem to be the problem as the sill plate appears to be a good 4-6 inches above the soil and the owners said there is not water ponding at the foundation when it rains.
