How to Upgrade Basement Windows in a DC Rowhouse Safely

In a DC rowhouse, basement windows are small openings with big consequences. They influence drainage, dampness, safety, and how closely the finished work has to match the original facade.

Older rowhouses were not built around modern window sizes. Basement openings can be odd dimensions, and they often need careful measuring and custom fabrication. That is normal, not a sign that the project has gone wrong.
