Town/Neighborhood: Baldwin
Borough/County: Nassau County
Construction Type: Residential
Category: Foundation Repair, Foundation Wall Restoration

Problem:

The homeowner reported signs of water penetration in the closet wall. Over time, this moisture intrusion risked damaging the structural components and promoting mold growth. Upon inspection, we discovered that the water was entering through the wall and floor cove joint, as well as through a cracked stone section at the exterior grade level. Immediate foundation and waterproofing repairs were necessary to prevent further deterioration.

Solution:

Work Area A: Closet Wall and Cove Joint (approx. 8 linear feet)
 We began by removing the existing closet shelves to access the affected wall area. We cut and removed drywall 12 inches above floor level, then removed the studs and baseplate for complete access to the wall/floor cove joint. Using a diamond blade, we ground the joint 3 inches vertically and 3 inches horizontally. We applied Basecrete 4.5 oz mesh-reinforced waterproof cement to fully seal the joint, ensuring a durable and watertight barrier. After the repair, we replaced all removed drywall, reinstalled the shelves, and restored the baseboard.

Work Area B: Exterior Grade Level Repair
 At the cracked stone on the exterior, we filled the missing section with waterproof repair mortar and parged the surface solid to prevent future water infiltration.

Conclusion and Call to Action:
This Baldwin, NY project successfully stopped active water intrusion, reinforced the foundation wall, and restored the interior finishes to their original condition. By addressing both interior and exterior vulnerabilities, the homeowner gained lasting protection against moisture damage.
