Window Repair vs Replacement for Historic Property in Washington DC

How Historic Windows Set The Rules For The Project

In Washington DC, the question is rarely "can I change the windows?" And more often "how much of the original fabric can be kept without creating bigger problems later?"

A historic facade can usually tolerate repair work much better than a full swap to modern units, as long as the frame, sill, and sash are still structurally sound.

The trick is separating cosmetic aging from actual failure, because old windows often look worse than they are.

When Repair Is The Better Choice

That may include replacing broken cords, reglazing panes, repairing muntins, consolidating rot, weatherstripping, and restoring paint layers so the assembly can move and seal properly again.
