Trusted Waterproofing for St. Louis Homeowners

St. Louis, MO is known for its historic neighborhoods, beautiful brick homes, and diverse terrain—but beneath that charm, many homes face serious crawl space and basement moisture issues. Whether you live in South City, the Central West End, The Hill, or beyond, St. Louis homes are built on clay-rich soil that expands, shifts, and traps water—leading to structural damage, mold growth, and air quality concerns.

At Crawlspace and Basement Medic, we deliver customized waterproofing systems to match the unique needs of St. Louis homes. From early 1900s basements to newer builds on the city’s edges, our solutions include encapsulation, sump pumps, dehumidifiers, and repairs designed to protect your foundation and family’s health.

What’s under your home affects everything above it—let’s keep it dry and safe.
