Custom Homes

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.

Commercial Construction

Commercial buildings are similar to homes – they house a family of small businesses. Many of our custom home clients were so impressed with how well we took we took care of their personal families, that they asked us to build their commercial project as well.

In the mid-1980s, GAST Construction expanded its capabilities by creating a permanent commercial construction division specializing in light commercial buildings, retail centers, automotive service buildings, boat maintenance shops for marina use and more in the Baltimore and Harford County area.

Whether your commercial construction plans are complete or if you need help from the concept on up, give GAST Construction a call.

Excavating & Demolition

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.

Additions & Garages

As long as people live in houses, there will be a need for room additions. It’s simple – lifestyles change! You might want to add a cozy sunroom, an in-law apartment, a detached garage or a grander entertainment space. The problem – room additions are much more difficult to realize than new home construction, because doing so essentially turns your existing home into a construction project that you’re living in!/p>

So whether you have a set of plans, a few ideas or just the feeling that you need something more, call GAST Construction today.

GAST Construction Company is your locally owned custom home builder. Our team of professionals is here to build you the home of your dreams with first class amenities.
