With its blend of historic homes, riverfront properties, and sprawling subdivisions, Naperville faces a wide range of foundation and water management challenges. Spring rains and snowmelt can overwhelm storm drains along the DuPage River, while clay-rich soils in neighborhoods like Ashbury and Hobson West contribute to foundation shifting and seepage issues.

Since 1979, Perma-Seal has been helping homeowners in Naperville, Lisle, Warrenville, and Aurora protect their homes from water damage and structural problems. Whether you live near downtown Naperville, in South Naperville, or off 75th Street, we offer solutions tailored to your home’s soil, structure, and location.
