Custom Window Sizes for Older Baltimore Rowhouse Openings

Presented by @bestenergyefficientwindowreplacementuco268

Anyone who has worked on an older Baltimore rowhouse knows the windows are part of the charm and part of the challenge, because the openings often do not match standard dimensions.

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

That usually takes more measurement, more planning, and a better understanding of what can be changed and what should be left alone.

Why Older Rowhouse Openings Rarely Match Standard Sizes

Older rowhouses in Baltimore often have window openings that are slightly out of square, taller or narrower than current stock sizes, or different from one floor to the next because the building has moved over time.
