Custom Window Sizes for Historic Homes in Old Mandeville, Louisiana

The Importance of Custom Windows

Walk Old Mandeville and you see it instantly: windows that tell the home’s story as clearly as the porch columns. That is why window work in these houses almost always calls for custom window sizes and careful planning. With a solid plan, you can preserve sightlines, improve comfort in our heat and humidity, and keep the structure dry during summer storms.

Navigating Historic Window Challenges

Most Old Mandeville frames have shifted with time, leaving openings that are neither level nor plumb. The telltale signs are racked frames, sash weight cavities, and plaster returns that make the opening smaller than it looks. Sizing to the tightest dimension, then shimming and insulating to square, produces a stable, tight installation.

Methods for Window Replacement

Clarify the replacement type before you ever pull a tape. Your options are a sash-replacement kit, an insert window set inside the old frame, or a full-frame replacement down to the rough opening. If the original jambs are sound and square enough, an insert can save plaster and trim. 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.

Measuring for Success

Measurements must be taken like you are building casework, not estimating a curtain rod. Measure Mandeville Window Replacement head, mid, and sill widths plus left, center, and right heights, and verify the diagonals to see how out-of-square the opening is. When the head is curved, build a cardboard or lauan template and label the spring points, then ship that with the order. Document plaster return depths and interior trim that you want to save, because that dictates frame depth and stool projection.

Permits and Regulations
