Crus was very helpful with good communication skills. He helped me understand the scope of my project and my options. The crew showed up on time and wasted none getting to work. The project was bigger than they were expecting for a crew of 2. They called in more help and finished up on schedule. Coast left the place clean.

Cruz the Estimator was very helpful answering all my questions when I was trying to decide whether to hire Coast Bldg. Products. When it came time to make an appointment to do the installation of my attic insulation Dominic called to say they had a cancellation and could send someone out the next day. The two men Jose and Rickie were on time, friendly and did a great job. I will definitely tell my friends.
