Best Window Types in Washington DC
In Washington, DC—a city where historic charm meets contemporary design—windows are far more than panes of glass. They shape a home's character, determine its energy efficiency, and directly affect everything from comfort to resale value. Whether you live in a Georgetown brownstone, a Columbia Heights condo, or a rowhome in Petworth, choosing the right window type can have a long-term impact on how your home looks, performs, and feels throughout the seasons.
Among the many options available, six window types dominate the residential scene across the District. These styles have earned popularity based on their ability to meet the unique architectural demands and climate needs of DC properties.
1-Double hung windows
Double-hung windows top the list. These are the most common style in Washington, DC homes for good reason. Both sashes slide up and down independently, offering better ventilation control and easier cleaning. In older neighborhoods like Capitol Hill and Shaw, many residents are upgrading their aging wood frames to vinyl double-hung options with Low-E coatings and insulated glass for year-round efficiency without compromising historic aesthetics.
2-Casement Windows
Casement windows are another top choice, especially in areas like Chevy Chase and Tenleytown where mid-century and newer homes are common. Hinged on the side, these windows open outward with a crank, sealing tightly when closed for superior air infiltration prevention. They're ideal for catching cross-breezes and work well in kitchens and bathrooms where ease of operation is a plus.
3-Sliding Windows
Sliding windows are frequently seen in DC basements and smaller homes, including those in neighborhoods like Anacostia and Brookland. These windows open horizontally and are excellent for limited wall space or egress areas. Their simple mechanism, affordability, and unobstructed views make them a practical and aesthetic upgrade for modern DC families.
4-Bay Windows
Bay windows are a favorite in larger, classic homes around neighborhoods such as American University Park and Crestwood. These multi-panel installations extend beyond the home's exterior wall, offering panoramic views, natural light, and a cozy space for seating or decor. Not only do they enhance curb appeal, but they also add usable square footage and significantly increase property value in Washington’s competitive market.
5-Picture Windows
Picture windows are fixed, non-operable panes that allow maximum light and clean views of DC’s skyline or tree-lined streets. These are often used in tandem with casement or awning windows and can be found in contemporary builds throughout Navy Yard and NoMa. Since they don’t open, picture windows are also highly energy-efficient and contribute to modern, minimalist interior aesthetics.
6-Wood Clad Windows
Finally, wood-clad windows are particularly relevant in Georgetown, Dupont Circle, and other historic preservation districts. These combine the charm of real wood interiors with aluminum or vinyl-clad exteriors that resist moisture, rot, and peeling. They meet local historic guidelines while delivering today’s thermal performance and security standards.
