Why Older Baltimore Rowhouse Openings Rarely Fit Standard Windows

Most older rowhouses were built in an era when openings were framed to the house, not to a catalog size. A half inch off at the head or sill can change the whole installation.

Settlement is usually the first culprit. Brick rowhouses move over time, and the opening may no longer be perfectly rectangular even if it looks fine at a glance.
