The Sebastian Guarantee

Our guarantee is value to the client first.

How do we do that?

100% of our work in the all-important Pre-Construction phase is free.

This includes initial budget development, subsequent refinements, value engineering, initial project scheduling, systems analysis, constructability reviews, and consultation during the entire design process, green building reviews, and more.

If at the end of this process, we have not proven our value, developed a budget that delivers the highest quality at the best price for your home, and earned your trust, you owe us nothing for our efforts and are under no obligation for further engagement. We believe in providing value to our clients first and are confident in our ability to do so, thereby earning our place on your project team.

Please contact John Sebastian at 214-528-4130 ext. 105 or for more information on our Proven Process or the Sebastian Guarantee.
