Trusted Waterproofing for Granite City Homeowners

Granite City, IL is a proud part of the Metro East community, known for its historic neighborhoods, hardworking families, and proximity to the Mississippi River. But its location also puts homes at risk of excess moisture. With flat topography, clay soil, and aging foundations, many Granite City houses suffer from crawl space humidity, basement leaks, and structural stress.

At Crawlspace and Basement Medic, we help homeowners take back control of their indoor environment. Whether you’re near Nameoki Road, in Wilson Park, or along Route 3, our vapor barriers, sump systems, and dehumidifiers are designed to keep your foundation dry and your air safe—year-round.

Moisture doesn’t wait to be visible—it damages quietly. We stop it early.
