I want to replace an old brick patio with bricks that are uneven, and unattractive. The space is about 500 sq ft. There are two trees located close to the house that will need to be removed. I need help in locating a reliable paving company in the Chicago area. Should I go directly to a big fancy paving company? I did visit several big box stores but the help was very limited. I also went ****** to one of the popular home services. I'm at a lost for where to start. Help!
