Custom Window Sizes for Historic Homes in Old Mandeville, Louisiana

Matching that look and fit requires measuring the actual opening and ordering custom units to suit. The goal is equal parts preservation and performance: keep the look, add durability and efficiency for Mandeville’s climate.

Navigating Historic Window Challenges

In older framing, you can count on openings being out of square by a quarter inch or more. The telltale signs are racked frames, sash weight cavities, and plaster returns that make the opening smaller than it looks.

Replacement Options for Historic Windows

Document plaster return depths and interior trim that you want to save, because that dictates frame depth and stool projection.
