We would be able to use their services on our out of state projects as needed. They would provide us with engineered sealed drawings and calculations quickly. Thank you for a professional job done well.

Been doing business with Dotec for a long time. While we are a regular/repeat company our jobs are small potatoes compared to most but that has never stopped us from receiving top notch service. I have recommended Dotec to many and will continue to when I have the chance.
