About Gridor Constr INC
From gridor.com
Our philosophy is to approach all projects as " Design Build ": with the contractor, engineer and owner ALL working together for a successful project completion. Our attention to detail even before construction begins results in the elimination of costly changes later in the project. It is our goal to address issues on paper before they become a crisis, thereby finding workable solutions for all parties with the minimum amount of expense and delay to the project.

What Gridor Constr INC is registered to do
The State classifies Gridor Constr INC as all other specialty trade contractors. That classification comes from the registration itself, not from us — it describes the work the business registered to perform, and it is not an assessment of skill or a limit on what they may quote for.
