In 1998 GAST Construction added an Excavation & Demolition Division to enable us to perform excavations, installation of footings, foundations, septic system, and complete building tear-downs. If you are building your own home or need one demolished in Harford County, Baltimore or Howard County, please contact GAST Construction for your excavating and demolition needs.

Our Excavation & Demolition Division also handles all major site work, lot clearing, grading, storm water management, preparation for parking lot construction and the installation of underground tanks.
