"I placed an order today with Santos after visiting the rock yard yesterday afternoon. I chose my pavers, called at 9am in the morning to place the order for seven pallets and all was delivered 4 hours later. Everything was placed exactly where I specified with no faults. Thank you so much for your excellent service ! Highly recommend."

"I recently had the pleasure of working with 9 Brothers Building Supplies in East Setauket for my retaining wall project, and I cannot speak highly enough of their services. From start to finish, they exceeded my expectations and provided exceptional support and expertise. When I first walked into their store, I was immediately greeted by friendly and knowledgeable staff who were eager to help with my project. Not only did they help with the design, but they also suggested the perfect product for my retaining wall. The team at 9 Brothers Building Supplies truly went above and beyond to ensure that I received the best price along with prompt delivery. Great job, 9 Brothers!"
