“It’s been a little more than a month since our patio renovation and our experience with Keystone from start to finish was nothing short of positive. From the beginning stages of reviewing a detailed diagram and presentation with Ron and Sarah, to demolition with Chase, and then most importantly, the masonry work with Jordan, Willie, and crew, everything was extremely well coordinated with Elvin and Ariana keeping us in the loop every step of the way. We are so incredibly happy with our new patio and can honestly say that we enjoyed the process as a whole given how smooth everything went and how fabulous everything turned out.”
