“Special thanks to Sammy and his team — their attention to detail & dedication were second to none (Yes, they did complete some of the work even if it was raining 🙂 ). They treated my home with care, communicated clearly throughout the process, and delivered a final product as needed. The patio is not only beautiful but also built to last, and it’s quickly become our favorite spot to relax and entertain.”

“To start, they assigned us with the most legit Project Manager (Jon!) that we could have ever hoped for. He knew every single detail about our project and owned managing it from the moment he showed up through the entire 8 weeks of the project. Jon was part of the carpentry team. Him along with his team Merv, Daniel, Jay and Levi, showed up on time every day, were happy to be working, were a positive influence on my kids, and cleaned up the job site at the end of every workday.”
