Custom Window Sizes for Older Baltimore Rowhouse Openings

What Makes Older Rowhouse Window Openings So Hard To Match

If you have worked on enough Baltimore rowhouses, you learn quickly that the opening on paper rarely matches the catalog size on the shelf.

That is why custom window sizes for older Baltimore rowhouse openings are often the practical answer, not the expensive luxury people assume they are.

For rowhouses, the shape and condition of the rough opening matter as much as the window itself. If those two pieces do not align, the result usually shows up later as drafts, uneven operation, or water intrusion.

That is why experienced installers spend time looking at both sides of the wall before they recommend a unit. The size has to work with the structure, not just the tape measure.

If the old frame is solid, an insert replacement may be possible, but only when the existing frame gives a stable, level base.

That choice matters in Baltimore rowhomes because many openings have been altered several times over the life of the house.
