Custom Window Sizes for Older Baltimore Rowhouse Openings

Older Baltimore rowhouses are full of character, but their window openings rarely match modern stock sizes.

A window that is close but not quite right can leave gaps, create draft problems, complicate flashing, and make the finished job look forced.
