Hello, (My first post here!) I had a new concrete patio done about a month ago. I noticed that the edges of the patio footing does not go all the way to the sidewalk level, and it is jagged and uneven. The edge of the footing is a foot away from the sidewalk, and 1-3 inches above the sidewalk level. (Please see the pictures). The contractor says this is normal. I am concerned that when it rains, the moisture will get under there and the edges will eventually crumble. And not to mention it looks ugly from the side. Is this really normal, or should I ask the contractor to fix it to reach the level of the sidewalk? Thanks for your help!
