This is an existing home. not a house that was just built 16 months ago. The roof overhangs. We all know "brick is porous". If there were any problems - there would be mold in the basement, etc. Thr mortar in the brick would be showing signs of water damage. Brick has soil placed against it all the time. Sometime not a good thing. Sometimes, no biggie. Like I stated earlier - slope the soil away from the dwelling. Coupled with the roof overhang, and life is dandy. If you want piece of mind you can dig it out and tar the brick. Me, I wouldn't if it were my home, but thats me. Dig deep enough and you may find it's already tarred. By the looks of the age of the concrete steps - There has always been a wall there, the house most likely had a wooden wall at the time it was built. It rotted. Based on the size of the euoynomus by the block the wall is about 24 to 30 months old. .
