Custom Size Windows for Narrow DC Rowhouses

What Makes DC Rowhouse Openings So Hard To Standardize

Narrow DC rowhouses are often built with openings that do not match today’s off-the-shelf window dimensions. Because the opening itself is the limit, not the catalog, custom fabrication is often the cleanest path.
