Window Replacement Before and After: A DC Rowhouse Renovation Story

Why The Old Windows Were Failing

The review is usually about whether the new units respect the original character. A correct muntin pattern, sash thickness, and frame depth can do more for approval than a long list of product features.

The original windows were part of a historic streetscape, but they were not performing well enough to keep. That tension is common in Federal-style rowhouse window replacement Washington DC and Victorian rowhouse window restoration DC projects alike.
