Custom Window Sizes for Historic Homes in Old Mandeville, Louisiana

The Importance of Custom Windows

Older houses around the lake were built before standardization, which means the window holes often land between current sizes. The answer is usually custom window sizes for historic homes in Old Mandeville Louisiana, which respect the original openings while upgrading the envelope.

Replacing windows in an old wall is a craft exercise in measurement, flashing, and joinery as much as product selection. When you respect those fundamentals, the house stays dry, stronger against wind, and visually intact.

Measuring and Selecting Windows

Begin by field-measuring every opening, one by one. Expect sills and jambs to be out of square by up to half an inch, so take three width and three height measurements per opening and work off the smallest. Do not forget to note the wall depth so the new unit's jamb matches the interior plaster or shiplap without a proud edge.

Next, choose whether a sash kit will solve it or if you need a full-frame custom window. Sash packs keep your interior casing, but they demand a solid, square frame to run new balances and seals correctly. Going full-frame exposes the rough opening so you can cure rot, correct the sill pitch, and match the original lite pattern.

Material Choices for Windows

Material choice here is not just aesthetic, it is survival in South Louisiana humidity. The tradeoff of vinyl window replacement vs wood windows in South Louisiana humidity depends on how you build and maintain.
