The front "steps" to our house is a poured concrete thing. (Don't know what to call it---it's really not so much steps (though there are two of those) and more of a raised concrete rectangle a few feet on a side.)
Inside on the basement, where this thing intersects the exterior wall, there are bricks, cinder blocks, etc, which aren't square and protrude from the wall.
A handy friend said what happens is that when people make the front steps thing, they use some kind of fill, and the cluttered masonry is just them doing a crappy job of organizing the fill.
It's fine functionally, but it looks like crap. Instead of just smoothing it out with cement or whatever, he suggested first trimming it with some kind of small jack hammer-like thing (I think he said a "hammer drill"). Is that a reasonable idea? Or is there a better way to repair it?
