Dumbarton House to Close for Renovations

Georgetown’s Dumbarton House, 2715 Q St. NW, the Federal-period museum and headquarters of the National Society of the Colonial Dames of America, will close for about six months beginning in October. The last day that the museum will be open to the public will be Sunday, Oct. 23. The reopening, following replacement of the climate-control system, is expected in April of 2017.

Following “repeated failures in Dumbarton House’s HVAC system and a careful study of the museum’s 26-year-old setup,” the decision was made to temporarily close to install a geothermal system and carry out other upgrades. During the period that the work is underway, the staff and collection will relocate. “Dumbarton House on the Road” programming is being developed.

The contractors for the project, funded in part by the National Endowment for the Humanities, are: Quinn Evans Architects, Gipe Associates, Corbett Construction, Wendy Jessup & Associates and Watson & Henry Associates.
