CURTAIN WALL
REPAIR & SERVICES
IN WHITESBORO, TX.
Griffin Restoration is headquartered right here in Whitesboro. Whitesboro's commercial building stock has a median year built of 1977 — many facades on Main Street and the US-377/US-82 corridor are now approaching 50 years old, well past the service life of original curtain wall sealants and glazing components. We know these buildings, and we're minutes away when you need us.
What Curtain Wall Repair Includes
Complete curtain wall repair and maintenance services — from wet seal replacement to full panel and infill replacement on commercial facades.
Wet Seal Replacement
The exterior silicone or polyurethane sealant at curtain wall joints is the primary weather barrier in face-sealed systems — and the first component to fail as buildings age. On Whitesboro's older US-377 and Main Street commercial facades, original wet seals from the 1970s and 1980s are long past their design life and are allowing moisture infiltration that damages interior finishes and insulation well before it's visible.
We remove all deteriorated sealant, prepare joint substrates, install correct backer rod, and apply commercial-grade silicone matched to the system's movement requirements. Being headquartered right here in Whitesboro means rapid mobilization — no travel time premium, no delay when weather events create urgent repairs.
Gasket & Dry Glazing Repair
Many mid-century commercial curtain wall systems used EPDM or neoprene gaskets and dry-glazing tape to retain glass and panels. After 40-50 years of North Texas heat, freeze-thaw cycling, and UV exposure, these materials harden, shrink, and crack — creating infiltration pathways that wet seal repair alone cannot address.
We replace gaskets in kind, matching durometer and profile to the original system specification. Where original manufacturer components are no longer available, we source tested-compatible replacements and document the substitution for your building records.
Leak Investigation & Diagnosis
Visible interior water damage rarely marks the actual leak source in a curtain wall system. Water enters at a failed joint, travels within the wall assembly, and exits at a lower point — sometimes meters away from where it entered. Without systematic investigation, repairs chase the symptom rather than the cause.
We perform AAMA 501.2 water infiltration testing combined with visual inspection to confirm infiltration pathways before writing a repair scope. For Whitesboro buildings on the US-377/US-82 corridor where heavy truck traffic generates ground vibration, we specifically evaluate pressure plate connections and frame joints that are vulnerable to vibration-induced fatigue.
Panel & Infill Replacement
Hail impact, long-term water infiltration behind panels, and thermal break failure in older insulating glass units eventually require panel replacement rather than sealant repair. Whitesboro's exposure to severe North Texas hail makes impact-damaged panel replacement a recurring need on commercial buildings throughout the US-377/US-82 corridor.
We source replacement panels matched to the existing system's dimensions, finish specification, and glass performance requirements. Full infill replacement is staged to minimize building exposure time and interior disruption. Our local headquarters means no extended mobilization windows — we work on your schedule.
Industries We Serve in Whitesboro
Whitesboro's Aging Facades — and the Economic Pressure to Act
Whitesboro was incorporated on June 2, 1873 — one of Grayson County's oldest municipalities. Its commercial building stock reflects that history: the median year built is 1977, placing the majority of Main Street and US-377 corridor facades at or beyond the 45-50 year mark. Many of these buildings have never seen a comprehensive curtain wall evaluation, let alone systematic sealant or gasket replacement.
That changes with the regional economy. Texas Instruments' $30 billion semiconductor fabrication campus and GlobiTech's $5 billion facility are under construction in Sherman — just 22 miles east on US-82. The workforce, supply chain businesses, and service firms following that investment are evaluating Whitesboro commercial space now. Buildings in competitive condition will capture that demand. Buildings with obvious facade deterioration will not.
Griffin Restoration is headquartered right here in Whitesboro. We've worked on commercial buildings throughout northwest Grayson County and understand the specific challenges these structures present — from the Younger-Sullivan House block's historically sensitive facades to the heavy-duty US-377/US-82 corridor where truck traffic compounds building envelope wear.

Curtain Wall Repair FAQ
What causes curtain wall systems to fail on commercial buildings?
In Whitesboro, curtain wall failures are driven by the compounding effects of age and climate. The city's commercial building stock has a median year built of 1977 — meaning many facades are approaching or past the 45-50 year mark where original wet seals, gaskets, and dry-glazing components are well past their service life. North Texas delivers a punishing combination: hail events capable of 2-3 inch stones, hard freeze cycles that drive moisture into any open joint, and summer heat exceeding 100°F that hardens and cracks elastomeric sealants. Whitesboro's location on the open Grayson County plain, with minimal urban buffering, means buildings absorb the full force of each weather cycle. Heavy truck traffic on the US-377/US-82 corridor also introduces ground vibration that accelerates sealant joint fatigue in adjacent commercial buildings.
How do you diagnose leaks in a curtain wall system?
Curtain wall leak diagnosis starts with a systematic inspection of all wet seals, gasket conditions, and dry-glazing tape from the building exterior. Water entry points and the visible interior damage are rarely at the same location — water migrates behind panels before exiting at a drain point or unsealed penetration. We perform controlled water infiltration testing per AAMA 501.2 to confirm the source of infiltration before writing a repair scope. For Whitesboro buildings on the US-377/US-82 corridor where heavy-truck vibration is a factor, we also inspect for frame racking that opens joints along a curtain wall's pressure plate connections.
What is wet seal repair for curtain wall systems?
Wet seal is the silicone or polyurethane sealant applied to curtain wall exterior joints — between glass lites, between glass and frame, and at perimeter conditions where the wall meets adjacent construction. It is the primary weather barrier in face-sealed curtain wall systems. Repair involves complete removal of degraded sealant, substrate cleaning and priming, installation of correctly sized backer rod, and application of commercial-grade silicone formulated for the wall system's movement. Griffin Restoration is headquartered right here in Whitesboro — we're on-site fast when weather events create urgent wet seal failures, and we access multi-story joints from our 56' and 72' boom trucks without scaffolding.
How often should curtain wall sealants be inspected?
We recommend annual visual inspections and a professional assessment every 3-5 years for any curtain wall system. For Whitesboro buildings — where the median commercial structure is now pushing 50 years old and many have never had a comprehensive curtain wall evaluation — the first step is a baseline condition assessment to establish what's present and what's failed. After significant weather events, which Grayson County receives multiple times each year, inspect immediately. Catching a failed wet seal early prevents the cascade: water behind the panel, saturated insulation, corroded frame members, and interior finish damage that costs far more to repair than the original sealant joint.
Can curtain wall repairs be done on occupied commercial buildings?
Yes — and this is standard practice for commercial curtain wall work. Wet seal replacement, gasket repairs, and most panel work are exterior-access operations that do not require building shutdown. We stage work by elevation and coordinate boom truck positioning with building management to keep parking, loading, and tenant entries operational throughout the project. For Whitesboro buildings on the US-377/US-82 corridor, we plan equipment staging to avoid blocking access during peak business hours. Interior disruption during panel or infill replacement is limited to temporary protection in the immediate work zone.

Commercial Caulking & Sealant
Perimeter sealant at the curtain wall-to-masonry or curtain wall-to-structure transition is distinct from the curtain wall wet seal — and equally critical to the building envelope. We treat both as part of a complete scope.
