Client Testimonials
“ Castillo Bay Builders did an amazing job! The whole process was very easy and fast, allowing room for any questions all throughout the fencing project. There was a sense of comfort and assurance from day one, that I know I wouldn’t have gotten anywhere else. They checked in and see how it was to our liking and made sure that we approved of every detail, making sure that we were satisfied customers. Have definitely recommended and will reach out again for future projects. ”
