Introduction
As a Project Manager at HPRe+D, I see firsthand how New York City weather can turn a minor entry point into a major structural liability. At 2457 Frederick Douglass Blvd, our team was called to address a critical breach where water was entering through the building's exterior door threshold.
The Challenge: Building Envelope Breach
Water intrusion is one of the most common issues for Harlem properties, especially at high-traffic entry points.
KEY SERVICES PROVIDED
We began the project by conducting an in-depth inspection to assess the extent of the damage. Our team identified areas where drywall and insulation had sustained water damage, particularly in the lower portions of the walls and ceiling.
Tear Out Water-Damaged Drywall:
In the affected areas, 5/8" drywall was carefully removed up to a height of 2 feet.
The tear-out process was performed efficiently to minimize disruption, without the need
for bagging, allowing us to prepare the site for the next stages of restoration.
Tear Out Wet Insulation:
Wet insulation from the ceiling was removed and bagged to prevent contamination and
reduce the risk of mold growth. This step was critical for restoring a safe, dry
environment and preventing further structural damage.
Protection and Trade Labor:
Skilled trade labor was provided to ensure proper removal and disposal of
construction debris. Dust control measures were implemented to keep the work
area and surrounding spaces clean, while also protecting nearby common areas.
Coordination with Property Management:
We maintained close communication with the property management company to
ensure smooth project execution. This helped minimize disruptions to occupants
and streamlined the entire mitigation process.
The client reported active water infiltration occurring through the door.
Our team conducted a thorough assessment to locate the exact path of the water.
Unchecked, this moisture would have compromised the interior subflooring and masonry.

The Solution: Liquid-Applied Membrane Technology
To provide a long-term solution, we moved beyond temporary fixes and applied a professional-grade, liquid-applied waterproofing system.
Surgical Preparation
Our team prepped the area and utilized precision taping to ensure the new barrier integrated seamlessly with the existing structure.
Precision Application
We applied a high-performance white waterproofing membrane across the entire threshold and extended it up the vertical surfaces to create a "watertight boot".
Seamless Integration
The application covered the transition from the doorway to the exterior drainage areas to ensure 100% protection.

The Result: A Protected Investment
The finished project transformed a point of vulnerability into a point of strength for the property.
Full Mitigation
The building's interior is now fully shielded from wind-driven rain and pooling water.
Asset Preservation
By stopping the leak at the source, we prevented the need for expensive future mold remediation or floor replacement.
Professional Finish
The clean, white membrane provides a clear visual indicator of a well-maintained property.

Project Manager’s Perspective
Water intrusion issues can escalate quickly if not addressed at the source.
This project demonstrates the importance of properly diagnosing entry points and applying a complete waterproofing system rather than temporary surface fixes.
At HPRe+D, we provide both preventative and corrective waterproofing solutions tailored to the specific conditions of Harlem buildings.
