New Orleans has the highest ambient humidity of any major U.S. city. Outdoor humidity averages 75 percent, and indoor humidity in older homes without central air often exceeds 65 percent. When water hits your hardwood floors, that moisture does not evaporate naturally. It sits, migrates deeper into the wood, and spreads to the subfloor and joists. Pier-and-beam foundations, common in homes built before 1960, make this worse. The crawl space under your floor acts as a moisture reservoir. Water pools under the house after heavy rain, evaporates upward, and condenses on the underside of your flooring. This creates a constant cycle of wetting and drying that accelerates wood rot and mold colonization.
We understand how older New Orleans homes are built. Most restoration companies treat every structure the same. We do not. Shotgun homes have minimal subfloor ventilation. Creole cottages have wood sills sitting inches above grade. Garden District mansions have crawl spaces that flood during tropical storms. Each property requires a different drying strategy. Grand Water Damage Restoration New Orleans adjusts airflow, dehumidification capacity, and drying time based on your home's age, construction type, and foundation system. We also know which local lumber yards stock matching flooring for historic homes and which finishes hold up in high-humidity environments. That local knowledge is the difference between a floor that lasts and one that fails again in six months.
