Historic District Window Upgrades in Baltimore: Balancing Preservation and Performance

Why Historic Baltimore Window Projects Need A Different Playbook

Baltimore’s historic rowhouses and attached homes can look simple from the street, but window work on them is rarely straightforward.

If the home sits in a protected district, the question is not only whether the old sash is tired or drafty, but whether the proposed change fits the building’s period character.

Choosing Between Repair, Restoration, And Replacement

A well-executed repair can preserve the house’s look and often costs less than a full replacement, especially on elevations where custom sizing would drive the price up.
