When planning custom window sizes for historic homes in Old Mandeville Louisiana, aim for authentic profiles with contemporary durability.

Measuring for Custom Windows in Historic Homes

On older homes, no two openings are exactly alike, and plaster, cypress, and trim hide surprises. The first pass is a full measure inside and out, a level and square check, and a rot assessment with an awl so the scope is clear. I map the frame profile, stool projection, and existing reveal so the new window lands flush with interior trim without odd gaps.

When the existing frames are square and sound, a sash kit can deliver better glass without tearing out interior millwork. If decay has crept into sills or the frame has racked, move to full frame replacement sized to the opening.

Selecting Durable Materials for Custom Windows

Between daily humidity swings and onshore breezes, materials matter in Old Mandeville. For period accuracy, wood still rules, but species and cladding determine how it holds up.

Wood options: treated pine is budget friendly but needs impeccable sealing, while dense species like mahogany or old growth cypress resist rot better. Aluminum clad wood gives you wood inside and a weatherproof skin outside, which helps in daily Gulf moisture. For large custom sizes, fiberglass maintains stiffness and finish in our climate. Use vinyl where budgets are tight, but stick to higher grade, reinforced frames so sashes do not deflect.
