"Rome came the next day, explained everything, and most importantly he was a guy I instantly felt I could trust. No games just an experienced concrete guy fixing our concrete problem. Will hire again and recommend to others."

"Did a great job and were quick."

"Excellent!! I would give John my highest recommendation. My back yard was in bad shape, basically unusable. John removed the old chain link fence along with all the sod, pavers and concrete. He replaced the grass with a beautiful 35 ft x 50 ft sport court. I asked John if he could build a wood privacy fence around the court. I couldn't find a contractor willing to do both the concrete and the fence. While John doesn't specialize in fences, he said "no problem". I also asked John if he could break up, remove and replace my old driveway and patio. Again "no problem, happy to do so". Both the sport court and driveway were large pours, 20+ yards each. John's crew did a great job and took great care to assure the slabs were perfect. John is a perfectionist and it showed in all of his work. John has an excellent work ethic and he always showed up on time and was always at the house when he said he would there!! In addition John finished the project early. It took less time than he had estimated. It was a big project and it completely transformed my back yard. John's prices were very reasonable and were SIGNIFICANTLY less than other bids. I added a few extras along the way that we hadn't planned on and they were all very affordable. The quality of John's work is impeccable. He is a true craftsman and artist. While John specializes in concrete, he really went above and beyond building the cedar fence. It is beautiful and incredibly well built. My neighbors are all impressed as well!"

"They were very responsive up front and scheduled the work quickly. Arrived on the day and helped us complete some other work at no additional charge while waiting for cement to arrive. Unfortunatley one of the workers walked across the patio and left mud boot marks that will not come out. We attempted to contact Sam multiple times however, after the first time he answered via text he stoped responding and never came out to address the issue. We are now stuck with permanent boot marks in our patio. They also requested to be paid in full up front but backed off when we offered to put half down. Otherwise we were pretty happy with the work but very disappointed that they did not respond or even come by to see if there was anything they could do to help fix the issue."

"They were great!!! Love my deck!"

"I hired them for big patio. I was planning to get the patio built around existing steps. Venly came up with an idea of rebuilding the step with a better design. When the work done, the quality and look exceeded my expectation. The crew was fast and easy to communicate. Thanks"
