About Grant

Grant Haertel started in the Architectural Sheet Metal and Cladding Industry in 1988. Grant started his career fabricating flashing and parts in a sheet metal shop. He then moved out in the field and trained in the proper installation of flashings and various metal roofing and cladding systems. After becoming proficient in fabrication and installation, Grant moved into the office where he learned CAD drafting and drew all the shop drawings and details for the company. From there he transitioned into estimating and finally into project management.

Grant has been a Senior Estimator and Project Manager for the last 20 years specializing in all types of exterior cladding systems: single skin panels, ACM composite panels, aluminum plate panels, perforated and imaging panels, insulated foam panels, fiber cement panels, phenolic panels, terra cotta panels, fin and sunscreen systems, to name a few. Grant likes the challenge of custom panel systems that others are afraid to tackle head-on.
