Custom Window Sizes for Older Baltimore Rowhouse Openings

Why Older Baltimore Rowhouse Openings Rarely Match Standard Window Sizes

After a few window jobs in older rowhouses, it becomes obvious that many openings are just off enough to make stock sizes a poor fit.

Older masonry rowhouses often carry years of settling, patching, and past repairs, so even openings that look square can vary more than modern products allow.

This is the point where custom sizing stops being a luxury and starts being the practical choice.

How Custom Sizing Solves Measurement Problems

• Unusual proportions in historic front elevations
• Clearance issues around interior plaster or exterior brick

A proper field measurement has to look beyond width and height, because depth, squareness, and the surrounding materials all affect the final fit.

That is one reason full frame replacement and insert replacement are not interchangeable in older homes.

If you are budgeting, it helps to expect custom work to cost more than standard stock replacements, especially when the opening needs repair before the new unit goes in.

What The Installation Process Looks Like In A Rowhouse
