Custom Window Sizes for Older Baltimore Rowhouse Openings

What Makes Baltimore Rowhouse Openings So Tricky

In older Baltimore rowhouse openings, the dimensions can be just off enough that a stock window fits badly, even when it looks close from the curb.

Measuring Older Openings Before You Order Anything

The first rule is simple, measure the actual opening, not the old sash, interior casing, or whatever trim happens to be hiding the edges.

For a rowhouse, width and height should be checked in multiple spots, then the smallest consistent measurement usually becomes the working number.

If you are comparing products, keep a few practical points in mind:

- The manufacturer may allow some tolerance for custom sizing, but the opening still has to be measured carefully.

• Older masonry openings sometimes need repair before the new unit goes in.
• Interior and exterior trim choices can change the final visible size.

Those details are why custom sizing should be planned with the installation, not tacked on at the end.
