Had a large retaining wall built to contain back yard. They didn't use any fabric on the inside of the wall so my backyard keeps seeping through the blocks and dropping in level as it erodes and escapes. The blocks also are not snug fitting and have very large gaps in places that is also aiding in the erosion. The wall isn't level on top and looks like hills and valleys when you look down it. They cut every corner they could and rushed the work. I don't know how they are on landscaping but they can't build a wall to save their lives so beware. I wasted $5,000.
