Careful Work in Old Georgetown
Spray foam insulation in Georgetown is a job for old houses and careful planning. Georgetown was founded in 1751 as part of colonial Maryland and predates the District by 40 years. Its Old Stone House, built in 1765, is the oldest standing building in Washington. The neighborhood was listed on the National Register as a historic district in 1967.
Old Georgetown Act
In 1950, Public Law 808 established the Old Georgetown historic district and required that the U.S. Commission of Fine Arts be consulted on any alteration, demolition or construction there. Interior insulation is normally different from exterior alterations, but anything touching the roof, windows or facade needs to go through that review. Plan with it in mind.
Typical needs
Georgetown townhouses tend to have masonry walls, tall ceilings, attics or roof cavities with thin insulation, and basements close to the river's damp ground. The roof layer and the basement are usually the first targets. For the walls, solid brick needs careful thought before any interior insulation goes on.
Near the river
Lower Georgetown sits along the Potomac and the C&O Canal. Basements here can be damp; water management comes before insulation.
Narrow lots and access
Georgetown townhouses often have no side yard and limited parking. Our equipment runs hose from the truck, so let us know about access, alley entry and parking when you call. We protect stairs, floors and woodwork along the hose path.
Renovations
Many Georgetown houses are renovated in phases. When walls or ceilings are open, that is the time for foam. Get a free estimate

Georgetown Questions
Does insulation need Commission of Fine Arts review?
Interior insulation normally does not alter the exterior. Roof or facade changes do need review. Check before planning roof work.
Can old brick walls be insulated?
Solid masonry needs careful moisture planning. We usually start with the roof and basement.
My basement near the canal is damp. Can it be insulated?
Water comes first. Once it is dry, closed-cell foam on the walls and rim works well.
Do you protect old plaster and trim?
Yes. We cover and mask before any work.
