Add square footage without leaving the neighborhood you love.
Moving is expensive, and inventory around Hagerstown stays tight. A well built addition gives a growing family the space it needs while keeping the location, the schools, and the yard you already have.
Our crews handle the full build in house, from footings set below Maryland's frost line to a roofline and siding that match your existing home so the new space never looks bolted on. We pull permits through the City of Hagerstown or Washington County, coordinate any HOA architectural review, and keep the jobsite clean from the first day to the last.

Home Addition Questions, Answered
Do I need a permit for a home addition in Hagerstown?
Yes. Any addition that adds square footage needs a permit and inspections through the City of Hagerstown or Washington County, depending on your address. We prepare the drawings and manage the permit process as part of the job.
Will the addition match the rest of my house?
That is the goal. We match rooflines, siding profiles, brick, and trim as closely as possible so the new space reads as part of the original home rather than an add-on.
How long does a home addition take?
Most residential additions run from several weeks to a few months, depending on size, foundation work, and the season. Maryland winters can affect concrete and framing schedules, and we build that into your timeline up front.
Do you handle HOA architectural approval?
Yes. Many Washington County developments require architectural review before work can start. We provide the drawings and specifications you need for submission.
Will an addition raise my property taxes?
Adding finished square footage can change your assessed value. We recommend confirming the specifics with the Maryland SDAT or the Washington County assessor for your property.
