If you are searching for custom window sizes for historic homes in Old Mandeville Louisiana, the key is to balance historic detail with modern performance.

Start With a Measured Survey That Respects the Building

On older homes, no two openings are exactly alike, and plaster, cypress, and trim hide surprises. I record tight and loose dimensions, verify head height runs true across the elevation, and mark any soft wood that will need dutchman repairs. I log sash weight pockets, parting bead widths, and casing thickness, since these details define whether we do full frame replacement or a sash pack.

When the existing frames are square and sound, a sash kit can deliver better glass without tearing out interior millwork. Extensive rot or a badly out of square frame usually calls for a full frame custom window built to the true opening dimensions.

Selecting Durable Materials for Custom Windows
