We completed a comprehensive restoration project for a multi-story apartment complex in Philadelphia to address extensive water intrusion issues. Our team identified and repaired significant damage to the flat roofing systems, including crumbling brick parapet walls and failing bituminous membranes. We also addressed structural masonry concerns, focusing on exterior brick cracks and deteriorating mortar joints that were compromising the building's envelope. Interior work involved remediating water damage across several units where leaks had caused bubbling paint, ceiling stains, and plaster deterioration. We focused on reinforcing window headers and sealing gaps where moisture had penetrated the living spaces. These targeted repairs restored the structural integrity of the masonry and ensured a dry, stable environment for the residents.
