CURTAIN WALL
REPAIR & SERVICES
IN DENTON, TX.
UNT's 963-acre campus spans buildings from Curry Hall (1912) through modern research facilities — a 110-year range of curtain wall and facade types. The May 2024 hail event added urgency across the university district and South Loop 288 commercial corridor. We diagnose and restore curtain wall systems on occupied buildings without interrupting operations.
What Curtain Wall Repair Includes
Comprehensive curtain wall restoration for commercial 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 many curtain wall systems.
For Denton's university and commercial buildings along the South Loop 288 corridor, wet seal replacement is the highest-impact single maintenance item — restoring weather tightness without requiring system replacement.
Gasket & Dry Glazing Repair
Compression gaskets in dry-glazed systems harden, shrink, and lose contact with glass edges over time, creating water infiltration paths that bypass visible sealant lines. We replace deteriorated EPDM and neoprene glazing gaskets at perimeter and interlock locations.
Denton's clay-belt soil movement and annual temperature swings accelerate gasket compression set — the gasket appears intact but no longer seals. Proper diagnosis distinguishes gasket failure from wet seal failure before work begins.
Leak Investigation & Diagnosis
Water infiltration in curtain wall systems rarely enters where it appears inside the building. We use AAMA 501.2 hose testing, visual inspection, and interior moisture mapping to trace the actual infiltration path — not just treat the symptom.
After the May 2024 regional hail event, many Denton buildings have undiagnosed curtain wall damage. Impact cracks in gaskets and sealant joints allow progressive moisture entry that worsens with each subsequent rain event.
Panel & Infill Replacement
Cracked or broken glass lites, damaged spandrel panels, and deteriorated aluminum infill sections require direct replacement to restore both weather performance and building appearance. We source replacement glazing and panels matched to existing system profiles.
For Peterbilt's 700,000-sq-ft Denton manufacturing campus and the university district's institutional buildings, panel replacement is often combined with full wet seal replacement for a comprehensive curtain wall restoration scope.

Why Denton Buildings Need Curtain Wall Service Now
UNT's 963-acre campus contains buildings from Curry Hall (1912) through modern research facilities — a 110-year range of exterior types requiring era-specific masonry repair, waterproofing, and curtain wall restoration. The university district's dense concentration of older masonry and glass curtain wall buildings makes it particularly vulnerable to Denton's severe weather pattern.
The May 2024 hail event produced golf-ball to softball-sized hailstones causing more than $2.3 billion in regional property damage. Many curtain wall systems absorbed impact damage that isn't visible from street level but allows progressive moisture entry with every subsequent rain.
Denton's median commercial year built of 1997 means a large share of buildings along South Loop 288 and the Rayzor Ranch corridor are in the 25-30 year range — exactly the window when original wet seals and glazing gaskets reach end of service life and require systematic replacement.

Curtain Wall Repair FAQ
What causes curtain wall systems to fail on commercial buildings?
Curtain wall failure typically begins with sealant degradation — UV exposure, thermal cycling, and building movement break down silicone and polyurethane wet seals over 10-15 years. In Denton, the May 2024 hail event produced golf ball to softball-sized hailstones causing more than $2.3 billion in regional property damage; impact damage to glass infill panels and aluminum frames accelerates sealant joint stress. UNT and TWU's campus buildings — spanning from Curry Hall (1912) to modern research facilities — represent multiple generations of curtain wall technology, each with era-specific failure modes.
How do you diagnose leaks in a curtain wall system?
We use a combination of hose testing (AAMA 501.2), visual inspection with borescope where accessible, and interior moisture mapping to pinpoint infiltration paths. On Denton's mid-rise commercial and campus buildings, leaks often trace to failed horizontal sill wet seals, deteriorated glazing gaskets at corners, or compromised perimeter flashings at the curtain wall-to-masonry transition — not always at the most visible joint. A proper diagnosis identifies the source, not just the symptom.
What is wet seal repair for curtain wall systems?
Wet seal repair involves removing deteriorated silicone sealant from the exterior face of curtain wall framing members, preparing the aluminum substrate and glass edge, and installing new commercial-grade silicone matching the original joint design. This is distinct from dry-glazed systems that use compression gaskets. The wet seal is the primary weather barrier in many curtain wall designs — when it fails, water enters the framing cavity and migrates into the building interior. For Denton's aging HALL-era and campus buildings, wet seal replacement is often the single highest-impact maintenance item.
How often should curtain wall sealants be inspected?
We recommend inspection every 5 years and replacement on a 15-20 year cycle, depending on UV exposure, building movement, and original sealant quality. After significant weather events — Denton sits in a severe hail corridor and experienced the May 2024 regional event — immediate post-storm inspection is warranted. HALL Park's earliest Class A office buildings at the CPDD corridor are approaching or past the 15-year threshold where wet seal replacement becomes necessary regardless of visible condition.
Can curtain wall repairs be done on occupied high-rise buildings?
Yes — and it's the standard operating condition for commercial curtain wall work. We phase repairs to maintain weather tightness on completed sections while work continues on adjacent bays. Our 56-foot and 72-foot boom trucks provide exterior access on low- to mid-rise buildings without scaffolding disruption to tenants. For Denton's UNT and TWU campus buildings and the South Loop 288 commercial corridor, minimizing disruption to ongoing operations is a core part of our project planning.
