This requires more robust systems, such as high-capacity sump pumps and extensive exterior drainage, pushing local costs to an average of $16,142 compared to the $5,233 national average.
Interior waterproofing, which manages water already inside, typically costs between $3,000 and $8,000. Exterior waterproofing, which involves excavating the foundation to apply a membrane, is more preventative but costs significantly more, ranging from $11,750 to $22,000.
