Welcome to GAST Construction Company

We have been creating homes since 1972.

Founded in 1972 as a masonry/framing contractor, GAST Construction has evolved to become a custom builder that delivers a top-quality finished product. GAST Construction has completed hundreds of projects including new custom homes, room additions and commercial buildings throughout Batlimore and Harford County.

Our new home portfolio includes styles and types from 1,000 square foot ranchers to 8,000 square foot estate homes, all linked by our philosophy of building what our customers want, with first class amenities.
