I chose CCL after getting several other quotes from different local companies to raise multiple areas of our sidewalk that had sunken and 'slid' away from the bottom of our porch step, leaving a huge gap. While CCL was the most expensive, I felt the quality of work they would perform and the materials they used were superior to the other less expensive quotes. Mike and Mark arrived early (after calling to see if it was OK to come a little early), did the job quickly, efficiently, patiently answered my questions as they did the work and cleaned up well afterwards. We are very pleased with the end result. At first I was a little worried that CCL was not located in the Windsor area, but in the end, their communications with me and the final product alleviated any fears. I would highly recommend CCL. If they say they can do the job....believe them! Thanks Andy, Mike and Mark!
