Excellent Experience Working with DE Group

This review is long overdue. As a local general contractor and roofing company owner, I truly appreciated the opportunity to work with DE Group. They took care of our team, communicated well, and worked with us in a way that felt fair and supportive from start to finish. They were a pleasure to work with and handled any issues or concerns more quickly and professionally than many companies we have dealt with in the past. Thank you guys!

Great Quality Work and Excellent Service

Mark, Mariana and the entire DEG team are great to work with. They oversaw the correction of a waterpooling issue within the commercial roof of my office in Pittsburg. They're honest, extremely insightful on water systems alongside accurate about pricing and efficient with their timing. The work is high quality, and I enjoyed working with them. I'd recommend DE Group to anyone!
