New Orleans averages 77 percent relative humidity year-round. That moisture penetrates every crack, gap, and unsealed penetration in your building envelope. Older homes in neighborhoods like the French Quarter, Marigny, and Uptown were built before modern moisture barriers existed. Many still have original wood siding, single-pane windows, and crawl spaces with dirt floors. When water gets into these assemblies, it does not dry out naturally. It accumulates. Spotting hidden water damage before it rots sills, studs, or joists is the only way to avoid catastrophic structural repairs. The combination of high outdoor humidity and poor original ventilation creates perfect conditions for concealed dampness to persist for months undetected.
Grand Water Damage Restoration New Orleans is familiar with the construction methods used across different eras in this city. We know where builders cut corners in the 1950s ranch homes in Lakeview. We know how Creole cottages handle water differently than raised shotguns. That local expertise means we know where to scan first and what materials are most vulnerable. We also understand the permitting and insurance landscape here. When we document moisture levels, we use the thresholds that local building inspectors and adjusters expect. Choosing a team that works in this market every day gives you faster, more accurate results and fewer disputes during the claims process.
