Basement Finishing for St. Mary's County Homes

We finish basements throughout St. Mary's County — Lexington Park, Great Mills, California, Leonardtown, Hollywood, Mechanicsville, and Charlotte Hall. Our crew handles the framing, insulation, drywall, flooring, lighting, and trim, and we coordinate the plumbing, electrical, and HVAC so you have one point of contact from start to finish.

Around NAS Patuxent River, a finished basement is often about flexibility: a guest suite for visiting family, a home office, or a separate living area that makes the house easier to rent or sell down the road.

Basement Permits in St. Mary's County

Finishing a basement turns storage space into living space, and that work is permitted through the county's Department of Land Use & Growth Management. The residential permit application asks whether the project includes plumbing — which any basement bathroom does — and the permit and its inspections can be tracked online in eTRAKiT.

If the plan includes a bedroom, the building code requires an emergency escape opening, usually an egress window with a window well. We cut in and install egress windows as part of the job. Homes inside Leonardtown's town limits also need the town's own zoning and building permits.
