About Winthrop Harbor, IL
Winthrop Harbor (ZIP 60096) is Lake County's northernmost community (~6,700 residents) at the Wisconsin border, home to North Point Marina — Illinois' largest marina on Lake Michigan
The village's Lake Michigan shoreline exposure creates the most aggressive masonry weathering conditions in the service area — wind-driven spray, fog, and salt air erode mortar joints and spall brick at accelerated rates
Winthrop Harbor's lakefront properties along Sheridan Road and 7th Street face persistent moisture from lake-effect precipitation, requiring comprehensive waterproofing and sealed masonry surfaces
The village's proximity to Illinois Beach State Park means sandy coastal soils that provide good drainage but poor load-bearing capacity — all concrete flatwork requires engineered sub-base preparation
