Case Study: Waterproofing, Structural Repair, and Mold Remediation in Huntington, NY
Waterproofing in progress in the property in Huntington, NY

Project Overview

At Zavza Seal, we specialize in delivering comprehensive waterproofing, foundation repair, and mold remediation solutions tailored to each property’s unique needs. For a recent project in Huntington, NY, our team was called to address water drainage problems, structural instability, and mold issues at a residential property located at 59 Tanyard Ln, Huntington, NY 11743.


The Problem

The homeowner reported several serious concerns:

  • Inadequate drainage in the garage, causing standing water and structural wear.
  • A damaged structural column threatening the garage’s integrity.
  • Visible mold and water damage in the laundry room, particularly on walls and flooring.
  • Cracked exterior stucco and signs of moisture intrusion in various locations.

These issues, if left unresolved, could compromise the structural integrity of the property and pose health risks due to mold exposure.


Our Solution

Zavza Seal’s team provided a multi-phase solution that addressed the property’s specific concerns:


1. Garage Drainage System Installation

To eliminate standing water in the garage and prevent future flooding, we installed a new drywell system:

  • Cut a 14″ x 14″ square in the garage floor to create a drainage access point.
  • Excavated a 2-foot-deep pit, layered with 6 inches of gravel.
  • Installed a heavy-duty storm water pit drain (18″ high x 14″ wide x 14″ long) with a galvanized steel grate for durability.
  • Repaired a cracked 2 sq. ft. section of exterior stucco associated with the drainage issue.

This system allows water to be efficiently collected and redirected underground, keeping the garage dry and damage-free.


2. Structural Column Replacement

To restore structural integrity in the garage, we:

  • Removed the damaged support column.
  • Installed a 4″ concrete-filled steel column securely anchored to the existing footing.
  • Used steel plates on both ends for added strength.
  • Patched and troweled the garage floor to a seamless finish.

This ensured long-lasting support and prevented further settlement or damage.


3. Comprehensive Mold Remediation and Wall Repair in Laundry Room

Mold was found in multiple areas of the laundry room, requiring a full-scale remediation effort:

  • Foundation Wall: Removed residual mastic, applied Radon seal liquid vapor barrier, and installed mold-resistant sheetrock.
  • Damaged Doorframe Area: Removed sheetrock, applied mold killer, and replaced with new mold-resistant drywall.
  • Ceiling Soffit: Rebuilt missing wood soffit to restore structure and seal off potential mold entry points.
  • Baseboard Trim: Removed and treated mold at the base of all affected walls.
  • General Drywall Repair: Addressed all gaps and weak points in drywall, ensuring complete sealing.
  • Flooring: Reinstalled clip-together floor planks (provided by the homeowner) on top of mold-resistant underlayment, and installed new wood baseboard trim.

Optional Finishing: The customer also opted for sanding and painting of the affected areas for a fully restored aesthetic.
