An 84 National Sales estimator will perform all of the necessary takeoffs from your blueprints. He will research any unusual products specified in the prints and make sure they are available. Our estimators are equipped with the latest grid technology digitizers, which produce the most accurate takeoffs. They have the most up-to-date truss programs, so we can establish 100% certainty whether or not the specifications on the blueprints will be structurally sound. From rough framing to finished products to structural components, you can be sure that your job will be taken-off completely and accurately.
