CURTAIN WALL
REPAIR &
SERVICES.
Commercial curtain wall systems are the most technically demanding segment of the building envelope — and the most consequential when they fail. Griffin Restoration has been self-performing curtain wall sealant repairs, wet seal programs, and leak remediation across North Texas and Southern Oklahoma for over 26 years. We work from our own boom equipment, carry our own crews, and don't subcontract the work that matters most.
What Curtain Wall Repair Includes
Comprehensive curtain wall services — from wet seal replacement to full building envelope sealant programs for commercial high-rise and mid-rise structures.
Wet Seal Repairs
Wet seal systems — the silicone sealant beads applied to the exterior face of curtain wall framing — are the primary water barrier in most commercial glazing assemblies built between the 1970s and 2000s. When silicone hardens, shrinks, or loses adhesion to aluminum or glass substrates, the seal opens and water tracks directly into the wall cavity. A systematic wet seal program replaces failed and failing sealant in a continuous sequence across an entire elevation, eliminating the leapfrog infiltration patterns that result from spot repairs.
Our crews assess sealant condition using visual inspection and probing at every joint before specifying the full scope. We match silicone formulations to the original framing system — structural, weatherproofing, and pressure-equalized designs each require different product selection. We work from our own boom trucks, eliminating swing-stage rental costs that inflate project pricing for multi-story buildings.
Leak Remediation
Active curtain wall leaks in occupied commercial buildings are urgent — water infiltration at slab edges, column covers, or spandrel panels can damage interiors, trigger mold growth, and create liability exposure for property owners and managers. Effective leak remediation begins with diagnostic water testing using AAMA 501.2 spray rack methods or hose testing to isolate the actual breach point rather than just treating the visible water stain, which is frequently feet or stories away from the entry point.
Once the breach is confirmed, we differentiate between wet seal failure, structural sealant separation, gasket compression loss, and framing deflection — each requiring a different repair approach. Our 26+ years working on commercial glazing assemblies across North Texas and Southern Oklahoma means we've seen the failure modes specific to curtain wall systems installed during the region's 1980s and 1990s commercial building boom, and we don't guess at solutions that haven't been confirmed by testing.
Gasket Replacement
EPDM and neoprene gaskets in curtain wall systems compress and set over time, losing the elastic recovery that maintains a weathertight seal against glass and panel edges. In the North Texas climate — with summer surface temperatures exceeding 160°F on south and west elevations — gasket degradation accelerates faster than in more temperate regions. Extruded and molded gaskets in pressure-plate and pressure-equalized systems require periodic replacement to maintain the system's design performance.
Gasket replacement requires careful disassembly of pressure plates and cap sections without damaging the structural silicone or framing finish. We source compatible EPDM profiles matched to the original system specifications, or — where original components are no longer available — equivalent ASTM C864-compliant profiles. On occupied buildings, we sequence the work bay by bay to maintain weather protection throughout the project duration.
Building Envelope Sealant Programs
A comprehensive building envelope sealant program treats curtain wall glazing sealants, perimeter sealants at floor-line transitions, expansion joints at structural bays, sealants at mechanical penetrations, and coping and flashing terminations as a single integrated system. This approach prevents the common failure pattern where glazing sealants are repaired but perimeter transitions continue to admit water that re-appears inside the building at interior finish materials.
Griffin Restoration structures envelope sealant programs as multi-year maintenance agreements or as one-time complete replacements, depending on building age and condition. For commercial property owners and managers responsible for multiple assets, we prepare condition assessment reports that prioritize remediation based on infiltration risk, remaining sealant life, and budget constraints. This allows capital planning rather than reactive spending on emergency repairs.
