United Waterproofing | Basement Waterproofing & Foundation Repair in Dover, NJ

Ice dams on roofs can force water into basement window wells, causing interior leakage. Our team addresses this by first identifying the entry point, often around window frames, then sealing and waterproofing the affected area from the inside. If significant water has pooled, we perform a basement tear-out and moisture control repair to prevent mold and structural issues. We also assess if your existing sump pump can handle the extra load, offering battery backup sump pump installation for reliable operation during winter storms.

This warranty means that if you sell your home, the new owner inherits the same coverage for the waterproofing systems we install. It protects against water leakage through the treated areas, giving you peace of mind that any future issues related to our workmanship or materials will be addressed at no additional cost.
