What Affects Crawl Space Costs in Alabama?
Alabama's hot, humid climate and expansive clay soils create ideal conditions for crawl space moisture problems. The state's long rainy season, averaging over 55 inches annually, means crawl spaces are under constant moisture pressure. Labor costs in Alabama are among the lowest in the Southeast, keeping project costs below the national average. However, homes in the Mobile Bay area and Gulf Coast often require more robust encapsulation systems due to extreme humidity and flood risk.
