How Victorian Rowhouse Windows Wear Out In DC

Victorian rowhouse windows in Washington DC tend to fail in predictable ways.

On a lot of older houses, damage looks worse than it is, and the frame is still serviceable.

The first question is not whether the window is old, it is whether the failure is local or systemic.

That distinction matters even more in historic districts, where original proportions and profiles are hard to match cleanly.

When Repair Is The Better Choice

Cases Where Repair No Longer Pays Off
