Customer feedback survey

Upon completion of plat construction, we send out the survey below, asking for feedback on the process from beginning to end. It will be reviewed by the Plat Engineering management and not the designers, so that you may provide your true and unbiased reflection. We value feedback because it helps us provide the best customer service possible. Thank you!
