CRC Concrete Raising and Repair had been contracted by the city to level the sidewalks in our neighborhood. I saw one of their trucks outside, so I asked them to look at my driveway, which was uneven. They came out and worked on it. They were very friendly and cordial people and I think they did the best job they could. One of the ends of the slab is still about one and half inches too low, but they say they can not raise it without the other end going down. So, they did a good job, but still I was hoping it would be totally level. They did give me a one year warranty on the work, so I will have to look at it again in a few months.
