Custom Window Sizes for Older Baltimore Rowhouse Openings

Why Older Rowhouse Openings Rarely Match Standard Sizes

If you have worked on enough older Baltimore rowhouses, you know the openings are often a little off, and sometimes a lot off, from today’s standard sizes.

A frame may look normal from the street and still reveal tapered sides, uneven sills, or out-of-plumb jambs once the trim comes off.

For many older homes, the better option depends on what is behind the trim, not what is visible from the room.

Labor, finish carpentry, and masonry conditions often matter as much as the sash itself.

In neighborhoods with strong preservation expectations, the window choice has to satisfy both performance goals and the street view.

The right product is the one that fits the opening cleanly and gives the house a finished look, not the one that simply costs the least.
