We hired CCS for a large patio installation. Sean came out, I believe, the day after I called to confirm I would like an estimate. He was on time, friendly, and took the time to explain to me what their plan was regarding elevation, materials, how the patio would look against other structures, etc. I felt like he was invested in knowing that I was comfortable with his plan rather than just trying to get the job at any cost. His estimate was thorough and, most importantly, reasonably priced.
The work crews showed up on time and got to work right away. They were friendly and were careful with the elements on my yard they had to manipulate (gutters, etc.). The work was completed in a day and a half, with multiple people make sure I knew exactly when we could use the patio. Everything was cleaned up, the lawn was seeded, and everything looked great!
CCS is not going to be the absolute cheapest option available, but you are absolutely going to get what you pay for -- quality work completed in a very fast, efficient timeframe.
I absolutely recommend CCS. I will call them the moment we have another concrete or paver project we need completed.
