John and Dave re-pitched an entire concrete patio and two smaller pieces by the patio doors beautifully. Previously, I had watched a heavy rain form a lake that was the proximate cause of the basement mold issue we had. These gentlemen worked an entire, snowy day on this project; besides one small crack which was so inconsequential that we didn't know about it until John pointed it out prior to the work commencing, the entire job went off flawlessly. Given the size of the patio, I was all set for all sorts of cracking. The professionalism and knowledge John and Dave displayed throughout was a joy to behold. You need sagging exterior concrete re-pitched? Your search has ended...thanks, Adirondack Basement!
