CURTAIN WALL
REPAIR & SERVICES
IN SHERMAN, TX.
Sherman's median commercial building dates to 1980 — and the $35 billion Texas Instruments and GlobiTech semiconductor investment is forcing every existing building to compete against a wave of new construction. Buildings along US-82, Travis Street, and the Heritage Row Historical District have curtain wall and glazing systems that are past their design service life. That's the gap we close.
What Curtain Wall Repair Includes
Complete curtain wall repair and maintenance for commercial buildings — from wet seal replacement to full panel restoration.
Wet Seal Replacement
Structural silicone wet seals at the glass-to-frame joint are the primary weatherproofing barrier in curtain wall systems. For Sherman's commercial buildings along US-82 and Travis Street — many dating to the 1980s — original wet seal sealants have exceeded their 15-20 year service life, and active infiltration is common.
We remove all deteriorated sealant, prepare glass and aluminum substrates, and install commercial-grade structural silicone matched to the original system. Our 56' and 72' boom trucks access upper-floor panels from the exterior without scaffold — reducing project cost and timeline on Sherman's multi-story commercial corridor.
Gasket & Dry Glazing Repair
EPDM glazing gaskets lose compression set over time, breaking the seal between glass and frame in dry-glazed curtain wall systems. Sherman's freeze-thaw cycling — including heavy sleet events recorded in the Sherman/Denison area — accelerates gasket degradation by forcing repeated expansion and contraction of the glass bite.
We source gaskets matched to the original framing system profile and re-glaze panels without frame removal where possible. For the institutional buildings on Austin College's campus (established 1849) and Wilson N. Jones Medical Center, we maintain documentation suitable for facilities maintenance records.
Leak Investigation & Diagnosis
Sherman has had 41 on-the-ground hail reports in the past 12 months. Post-storm curtain wall infiltration often goes undiagnosed until the next prolonged rain, by which time moisture has migrated through framing cavities to damage interior finishes. For buildings in Progress Park's 3,300-acre industrial complex or Texoma Technology Park, unresolved leaks create tenant liability issues.
We use AAMA 501 field water testing, weep drainage pathway inspection, and thermal imaging to trace infiltration to its true source. A written diagnostic report with recommended repair scope precedes any commitment to work.
Panel & Infill Replacement
Hail-damaged vision glass, cracked spandrel panels, and deteriorated metal infills undercut the building envelope performance and visual standard required in Sherman's competitive leasing environment. As the largest private investment in Texas history reshapes the area, existing buildings must meet the presentation standard new construction establishes.
We source replacement panels matched to existing systems on color, finish, and reflectivity — critical for the Heritage Row Historical District (S. Crockett St), where the Historical Preservation Board governs exterior alterations. Our team coordinates with preservation consultants when required.
Industries We Serve in Sherman
Why Sherman Buildings Need Curtain Wall Service Now
Sherman's commercial building stock has a median year built of 1980 — 46 years old. The downtown core and US-82 corridor contain structures from the late 1800s through 1960s where original glazing systems and sealants are decades past service life. Curtain wall infiltration in these buildings isn't a future risk; it's an active problem requiring systematic repair.
The $35 billion semiconductor investment — Texas Instruments' SM1 facility began production in late 2025, with GlobiTech's $5 billion wafer plant under construction — is driving new commercial development that older Sherman buildings must compete against. Curtain wall and facade condition is the most visible differentiator for tenants evaluating buildings side by side.
Located just 16 miles from our Whitesboro headquarters, Sherman is at the center of our core service area. We've worked on commercial, industrial, and institutional buildings across Grayson County and understand the specific conditions — expansive clay soils, 41 hail events in the past year, and the historic preservation requirements that govern the Heritage Row district.

Curtain Wall Repair FAQ
What causes curtain wall systems to fail on commercial buildings?
Curtain wall systems fail from sealant degradation, gasket compression loss, frame movement from differential settlement, and fastener corrosion — all accelerated by Grayson County's specific conditions. Sherman has had 41 on-the-ground hail reports and 83 severe weather warnings in the past 12 months. Freeze-thaw cycling opens mortar joints and stresses sealant bonds each winter, while clay-heavy soils exert lateral pressure on building foundations, transmitting movement up through facade framing. Sherman's median commercial building dates to 1980 — 46 years old — meaning many curtain wall systems predate current materials standards entirely.
How do you diagnose leaks in a curtain wall system?
We begin with a visual inspection of all wet seal joints, gaskets, weep holes, frame connections, and flashing, followed by AAMA 501 field water testing at identified failure points. For Sherman's older institutional buildings — the 1914 Wilson N. Jones Regional Medical Center, Austin College's mixed-era campus, and the Heritage Row Historical District structures — we combine water testing with thermal imaging to detect moisture in wall cavities before it reaches occupied spaces. A written diagnostic report with photographs precedes any repair recommendation. For the new Texas Instruments and GlobiTech construction near Sherman, we also provide commissioning-phase curtain wall inspections to catch installation defects before the warranty period expires.
What is wet seal repair for curtain wall systems?
Wet seal is the structural silicone applied to the exterior glass-to-frame joint in a curtain wall system. It is the primary weatherproofing barrier in most commercial glazing systems, and it fails predictably — typically between 10 and 15 years. For Sherman's commercial buildings along US-82 and Travis Street, where many facades date to the 1980s and 1990s, wet seal systems have already exceeded their design life and infiltration is active. Wet seal repair involves removing all deteriorated sealant, preparing and priming substrates, and installing new structural silicone matched to original specifications. On multi-story Sherman buildings, our 56' and 72' boom trucks provide access without scaffold.
How often should curtain wall sealants be inspected?
Annual visual inspections are recommended, with a comprehensive assessment every 3-5 years or after any major weather event. Sherman has averaged 2-3 severe hail events annually, with 41 ground-level hail reports in the past 12 months alone. For buildings near Progress Park's 3,300-acre industrial complex, Texoma Technology Park, or the Foundation Business Park — where new tenants are comparing facilities against a backdrop of $35 billion in nearby investment — a documented inspection and maintenance program is a competitive asset in lease negotiations.
Can curtain wall repairs be done on occupied commercial buildings?
Yes — this is standard practice and our specialty. Our 56' and 72' boom trucks reach curtain wall panels from the exterior without interior scaffold, keeping tenants fully operational. We sequence work around business operations, coordinate staging with property managers, and maintain egress at all times. For Austin College's active campus and Wilson N. Jones Medical Center's 24/7 operations, work sequencing and infection-control staging compliance are addressed in our pre-construction planning. Our self-performing crew eliminates subcontractor coordination delays — a critical advantage on occupied buildings where delays translate directly to tenant disruption.
