Custom Window Sizes for Historic Homes in Old Mandeville, Louisiana

Why Custom Sizes Matter for Historic Homes

Old Mandeville has homes with soul, and that character often lives in the windows. Matching that look and fit requires measuring the actual opening and ordering custom units to suit. With a solid plan, you can preserve sightlines, improve comfort in our heat and humidity, and keep the structure dry during summer storms.

Dealing With Non-standard Openings

Expect racked jambs and settled sills in these houses. The telltale signs are racked frames, sash weight cavities, and plaster returns that make the opening smaller than it looks. You measure to the smallest point and order to that, then plumb the new frame and insulate for a lasting seal.

Choosing the Right Replacement Method

The first choice is method, and that determines everything from order size to trim impact. In historic homes, you are typically choosing among sash kits, insert replacements, or full-frame replacements. Insert solutions shine when the jambs are solid and you want to keep original trim intact. If rot is present or water has tracked behind the casing, full-frame is the safer choice because it lets you address flashing and the sill pan correctly.

How to Measure for Custom Windows

Treat measurement as a finish task, not a quick takeoff. Take width and height in three places, shoot both diagonals, and record the tightest dimensions. When the head is curved, build a cardboard or lauan template and label the spring points, then ship that with the order. Record jamb depth and reveal targets so the interior casing lands clean without packing out.
