New Orleans averages 62 inches of annual rainfall and maintains year-round humidity above 70 percent. Our location at the confluence of the Mississippi River and Lake Pontchartrain creates a moisture-saturated environment. Historic flooding from hurricanes Katrina, Rita, Gustav, and Isaac left residual moisture in thousands of structures. Many homes absorbed water into wall cavities and never dried completely. Mold colonized these hidden spaces and continues growing years after the flood event. The pumping system that keeps our below-sea-level neighborhoods dry can fail during heavy rain, allowing street flooding and sewage backflow that introduces contaminated water into homes.
Grand Water Damage Restoration New Orleans works throughout Orleans Parish, Jefferson Parish, and St. Tammany Parish. We understand the construction differences between raised Creole cottages, shotgun houses, and modern slab-on-grade construction. Our technicians recognize how cast iron plumbing common in older properties deteriorates and leaks inside walls. We know which neighborhoods have poor drainage and chronic street flooding. This local expertise helps us identify likely moisture sources quickly. Property owners need assessors who understand how our unique environment and construction history affect mold growth patterns.
