Welcome to DEMARR Construction; your site development experts. 

Our Vision.


DEMARR Construction's company culture is based upon the principles that founder Bob DeMarr learned growing up in the Shipwright trade. There can be no mistakes when building a seaworthy vessel out of wood. Bob DeMarr sees the standards of residential site development no different than the standards he learned in the Shipwright trade. Reputation is the buoyancy that keeps our business afloat and we strive to be the best in terms of quality of work as well as delivering projects on-time and on-budget.
