Bill and I have just spent the weekend here at Gum Road. Whenever we're here we say how much we love this house, and we know we have your Dad (and you and all the great crew) to thank. So, before we leave, I wanted to send our warmest New Year wishes to your Dad and to you. We hope it's a great year for all!

We have had a relationship with Dieste Design Build for over twenty years. Having built two homes and a complete remodel of a third home for us, I can say without reservation that my husband and I have been more than pleased. From keeping a pristine job sight, to jobs completed in a more than timely fashion and open lines of communication, he had exceeded our high expectations.

We were uncertain what to expect in delving into such a large undertaking in tearing down an existing property and designing and building a home from scratch. We could not have selected a better builder than Mark Dieste and his team. Their work was top notch and the responsiveness to changes/adjustments made project a wonderful experience.

It was an honor to have our home included on the Bethany Cottage Tour and featured in Delaware Beach Life. We would recommend Mark Dieste Design Build without reservation.

Our family had the pleasure of working with the Dieste Design/ Build team and their great subcontractors, to build a wonderful home in Bethany Beach.

Mark has a great eye for the classic beach house with aged pine floors, spacious modern kitchens, and large porches with fun awnings, making each home uniquely Dieste.

We look forward to many great years there with all our family members.

Mark Dieste is absolutely the best builder in Delaware. Over the last 15 years, Mark has renovated two of our homes and built a new one for us. His work is superb and his eye for detail is incredible. He delivers on time, to your specifications and within budget. For example, he built our beach home from scratch with only two visits from us to check on his progress over a 6 month winter period.

His team and his subs are all excellent and a pleasure to work with. They follow up on all our requests and change orders without a hitch.

His work has a distinctive and elegant "Dieste look " which separates his homes from all others.

If we were to build another beach home we, unquestionably, would use Mark.

We are very happy Mark Dieste customers.

-Scott and Peggy Fechnay

Working with Mark Dieste and his team was a fantastic, seamless experience. Mark built us a beautiful custom home in Bethany and the experience from start to finish was excellent. Mark and his team take pride in the every aspect of their work. The custom work and craftsmanship is outstanding. Likewise, Mark’s team of subcontractors are professional, friendly and equally proud of their work. Every detail of our new home is fantastic and Mark literally stands behind everything.
