My concrete driveway and sidewalk were cracking and settling towards the house so I called around a got several estimates as I usually do and chose Jack Hammer Concrete (my first mistake). They replaced the sidewalk and driveway and all looked great......except for the sidewalk immediately in front of the entrance. Where before, the old sidewalk was dramatically sloping towards the house, it was now dramatically sloping away from the house! I made it clear that I was not happy with that but the owner had moved on to his next job and I was just a distant memory. Communication after the job was all but impossible. I did get a voicemail from the owner but repeated efforts to actually discuss, "mono a mono," failed. So much for any warranty promises. It's a shame because the work was good otherwise. Why ruin it with an unsightly slope when a gentle imperceptible slope would have sufficed? My second mistake was paying the invoice before we resolved the issue (Never again). I would not recommend Jack Hammer Concrete. read more
