"After receiving three quotes for our inground pool plaster, tiling, and coping work, we decided to go with Diamond Pool and Masonry—and we’re so glad we did. From the beginning, Raul, the owner, stood out as an expert in the field, and he truly delivered on that first impression. Once we provided the deposit, the work began immediately. Raul was extremely professional throughout the process. His deep knowledge of pool renovations and strong network of industry contacts made the entire experience smooth and stress-free. Communication was clear and consistent, and the project timeline actually exceeded our expectations. I can’t believe this is the same pool. Without hesitation, I would choose Raul and his team again for any future projects. Highly recommended!!"
