CURTAIN WALL
REPAIR & SERVICES
IN GREENVILLE, TX.
Doppler radar has recorded 85 separate hail events near Greenville — and L3Harris operates 3.7 million square feet across the 1,500-acre Majors Field campus, with buildings ranging from WWII-era hangars to modern aircraft modification facilities. Cumulative hail exposure on an aging industrial campus is not a cosmetic issue. It is a systematic envelope maintenance challenge.
What Curtain Wall Repair Includes
Comprehensive curtain wall restoration for commercial and industrial facilities — from wet seal replacement to full panel and infill work.
Wet Seal Replacement
Removal of failed silicone wet seal from curtain wall framing, substrate preparation, and installation of new commercial-grade silicone matched to joint design and movement requirements. The primary weather barrier on most curtain wall systems.
Greenville's I-30 corridor commercial buildings — median year built 1979 — have had one or fewer systematic wet seal replacement cycles. Buildings approaching or past 40 years with original sealants are absorbing moisture with every rain event. Proactive replacement costs a fraction of the water damage remediation it prevents.
Gasket & Dry Glazing Repair
Compression gaskets in dry-glazed systems harden, shrink, and lose sealing contact over time. We replace deteriorated EPDM and neoprene glazing gaskets at perimeter and interlock locations, restoring the pressure seal between glass and framing.
Hunt County's Blackland Prairie clay zone creates seasonal shrink-swell building movement that accelerates gasket compression set. For Hunt Regional Medical Center's hospital campus and L3Harris's precision manufacturing facilities, gasket failure that allows even minor moisture infiltration creates interior conditions incompatible with clinical or aerospace standards.
Leak Investigation & Diagnosis
Water infiltration rarely enters where it appears inside the building. We use AAMA 501.2 hose testing and interior moisture mapping to trace the actual infiltration path before remediation begins — essential for Greenville's mix of industrial, healthcare, and historic commercial building types.
With 85 recorded hail events near Greenville, buildings have often absorbed years of cumulative impact damage that isn't visible from street level. Post-storm hose testing on the Majors Field campus and I-30 commercial buildings identifies which bays were compromised before interior finishes and insulation are damaged.
Panel & Infill Replacement
Cracked glass lites, damaged spandrel panels, and deteriorated aluminum infill sections require direct replacement to restore weather performance and building appearance. We source replacement glazing and panels matched to existing system profiles.
For L3Harris's large industrial building envelope — hangars, test chambers, and manufacturing facilities across the 1,500-acre Majors Field campus — panel replacement is coordinated with wet seal replacement to address the complete building envelope and maximize the value of each mobilization.
Industries We Serve in Greenville
Why Greenville Buildings Need Curtain Wall Service Now
L3Harris occupies more than 3.7 million square feet across the 1,500-acre Majors Field campus — hangars, test chambers, flight-line shelters, and manufacturing buildings accumulated over 80+ years since Majors Airport opened June 26, 1942. That represents one of the largest concentrations of aging industrial building envelope in North Texas, with ongoing exposure to 85+ documented hail events.
Greenville's median year built of 1979 reflects a commercial and industrial stock where the standard wet seal replacement cycle has long passed on most buildings. Industrial Park West and the I-30 corridor contain 1960s-1980s structures where original waterproofing has exceeded its service life and building owners are absorbing preventable moisture damage.
Hunt County falls within the Blackland Prairie clay zone — seasonal shrink-swell cycles open facade cracks at mortar joints and stress curtain wall framing continuously. This soil condition amplifies the urgency of systematic sealant maintenance on all building types in the area.

Curtain Wall Repair FAQ
What causes curtain wall systems to fail on commercial buildings?
Curtain wall failure begins with sealant degradation from UV exposure, thermal cycling, and building movement — wet seals and glazing gaskets have a 10-20 year service life. In Greenville, two factors define the scope of the problem: Doppler radar has recorded 85 separate hail events near the city, with 1.75-inch hailstones striking on May 8, 2024. That cumulative hail exposure creates micro-fractures in sealant joints that compound with each subsequent event. L3Harris's 3.7M+ sq ft across the 1,500-acre Majors Field campus represents the largest single envelope exposure in Hunt County — 80+ years of accumulated hail impact, joint movement, and deferred maintenance across buildings from WWII-era hangars to modern modification facilities.
How do you diagnose leaks in a curtain wall system?
We use AAMA 501.2 hose testing, visual inspection, and interior moisture mapping to locate actual infiltration paths rather than surface symptoms. For Greenville's large industrial facilities — L3Harris hangar and manufacturing buildings, tilt-wall structures along Industrial Park West — leaks often trace to failed expansion joint sealants, deteriorated metal panel lap joints, or compromised perimeter flashings at roofline transitions. On commercial buildings along I-30, standard curtain wall hose testing isolates the specific bay and joint type responsible for interior moisture before remediation begins.
What is wet seal repair for curtain wall systems?
Wet seal repair removes deteriorated silicone or polyurethane sealant from curtain wall framing, prepares aluminum and glass substrates, and installs new commercial-grade silicone matched to joint width and movement requirements. On Greenville's Hunt Regional Medical Center campus and downtown commercial properties, wet seal replacement restores full weather tightness on the existing system — avoiding the cost and disruption of curtain wall replacement. For L3Harris's Majors Field campus buildings, we develop phased programs that address high-priority bays first while maintaining operational continuity across the facility.
How often should curtain wall sealants be inspected?
Every 5 years, with replacement on a 15-20 year cycle. Greenville's median year built of 1979 means many commercial buildings have had one or fewer sealant replacement cycles in their lifetime — and many older industrial structures on the I-30 corridor have had none. With 85 recorded hail events near Greenville, post-storm inspection should follow every significant weather event. Doppler records indicate cumulative damage that isn't visible until a building interior is compromised — by which point repair costs have already multiplied.
Can curtain wall repairs be done on occupied high-rise buildings?
Yes — and for Greenville's defense and healthcare facilities, occupied-building operation is the only option. L3Harris's aircraft modification operations at Majors Field run continuously; Hunt Regional Medical Center's patient care cannot be disrupted. We phase work to maintain weather tightness on completed bays, use our 56-foot and 72-foot boom trucks for exterior access on mid-rise buildings without scaffolding, and coordinate with facility management to avoid sensitive operational areas. For large multi-building campuses like L3Harris's 3.7M sq ft Majors Field, we develop phased multi-year programs that address the full portfolio systematically.

Commercial Caulking & Sealant
Expansion joints, loading dock seals, and perimeter transitions on Greenville's industrial buildings require replacement on the same cycle as curtain wall systems. Coordinating both scopes avoids redundant mobilization across large campuses like Majors Field.
