Founded in 1972 as a masonry/framing contractor, GAST Construction has evolved to become a custom builder and remodeler, offering a professional building process and delivering a top-quality finished result.

We have completed hundreds of room additions and remodeling projects for homeowners throughout the Baltimore, Maryland, metropolitan area. Our in-house excavation and demolition capabilities for installing footings, foundations and septic systems, and doing tear-downs are especially useful in creating custom room additions!
