CURTAIN WALL
REPAIR & SERVICES
IN PROSPER, TX.
Gates of Prosper Phase 3 brings 250,000 sq ft of new commercial space to a market where Costco, Barnes & Noble, and REI are raising the bar on building presentation. At the same time, Prosper's 2013-2015 commercial buildings are crossing the 10-12 year curtain wall maintenance threshold — the window where wet seals crack and gaskets compress. In a market where every building competes against gleaming new construction, deferred curtain wall maintenance shows.
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
The structural silicone wet seal at the glass-to-frame joint is the primary weatherproofing barrier in most curtain wall systems. At Prosper's median commercial build year of 2014, the oldest buildings are now in the zone where wet seal degradation is predictable and accelerating under repeated North Texas UV and thermal cycling.
We remove all deteriorated sealant, prepare and prime frame and glass substrates, and install commercial-grade structural silicone matched to original specifications. Our boom trucks reach upper-floor glazing from the exterior — no interior scaffold, no tenant disruption.
Gasket & Dry Glazing Repair
EPDM glazing gaskets in dry-glazed systems lose compression set over time, breaking the seal between glass and frame. Once gasket failure begins, patching is ineffective — the full gasket must be removed and replaced with one matched to the original framing profile.
For Prosper ISD's Rock Hill High School (600,000 sq ft) and the forthcoming 120,000-sq-ft administration complex, maintaining comprehensive gasket condition records is part of responsible institutional asset management. We provide before-and-after documentation suitable for facilities files.
Leak Investigation & Diagnosis
Curtain wall leaks rarely appear where they originate. Water enters at failed wet seals or gaskets and travels along aluminum framing before exiting at a different location — sometimes floors below entry. After Prosper's March and April 2024 hail events, many buildings have undiagnosed moisture infiltration paths that will appear during the next prolonged rain.
We use AAMA 501 water testing, visual inspection of weep drainage paths, and thermal imaging to locate the true source. A written diagnostic report with photographs and recommended repairs precedes any scope commitment.
Panel & Infill Replacement
Hail-damaged vision glass, cracked spandrel panels, and dented metal infills compromise both weathertightness and building appearance. At Gates of Prosper — where 270+ acres of retail ultimately demands 2M+ sq ft of curated tenant experience — facade blemishes are leasing liabilities.
We source replacement panels matched to existing color, finish, and reflectivity, coordinate with glazing suppliers on lead times, and complete replacements with minimal tenant disruption. Our self-performing crew model eliminates the subcontractor scheduling gaps that extend repair timelines.

Why Prosper Buildings Need Curtain Wall Service Now
Prosper's median commercial building was built in 2014 — meaning the earliest commercial stock is crossing the 10-12 year mark where original sealants, gaskets, and wet seals reach end of design life. This coincides with the moment of maximum leasing competition, as Gates of Prosper Phase 3 delivers 250,000 additional square feet in 2025.
The North Texas Blackland Prairie clay underlying Prosper swells up to 12% in volume when wet, exerting pressure on foundation walls and transmitting differential movement into facade systems. Hail events in March and April 2024 added impact stress on glass and metal panel systems across Collin County.
Prosper ISD — serving 32,197 students in 2025-26 and projected to reach 45,000-50,000 at build-out — has multiple large-format institutional buildings requiring systematic curtain wall maintenance programs. Our team works with both private commercial landlords and institutional facility managers to develop multi-year maintenance schedules.

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, and fastener corrosion — all accelerated by North Texas conditions. Prosper's Blackland Prairie clay soils can generate pressures exceeding 10,000 lbs/sq-ft on foundations, causing differential settlement that racks curtain wall frames and breaks glass-to-frame seals. The March 14 and April 8, 2024 hail events — with stones up to 2.5 inches — created impact damage on glazed facades across Collin County that may not yet have been fully assessed.
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 details, followed by controlled water testing per AAMA 501 field testing standards. For Gates of Prosper retail buildings, DNT corridor office towers, and Prosper ISD institutional campuses, we also use thermal imaging to detect moisture in wall cavities before it reaches visible surfaces. A written diagnostic report precedes any repair recommendation — so property managers have documented evidence of condition for insurance, warranty, or landlord-tenant purposes.
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 first line of weatherproofing defense, and it fails predictably — typically between 10 and 15 years under North Texas UV and thermal cycling. Prosper's commercial buildings from 2013-2015 are at exactly this threshold. Wet seal repair involves full removal of deteriorated sealant, substrate preparation and priming, and installation of new structural silicone matched to the original system. It restores full weathertight performance without curtain wall frame replacement.
How often should curtain wall sealants be inspected?
Annual visual inspections are recommended, with a comprehensive assessment every 3-5 years or immediately after significant hail events. Prosper recorded at least two major hail storms in 2024 — March 14 (1.5-2.5-inch stones) and April 8. For properties at Gates of Prosper — where national tenants and premium rents require demonstrably maintained building envelopes — a documented annual inspection program protects both asset value and lease negotiations. A 600,000-sq-ft campus like Rock Hill High School has enough curtain wall linear footage that systematic inspection scheduling is a maintenance budget necessity.
Can curtain wall repairs be done on occupied commercial buildings?
Yes — and it's the norm, not the exception. Our 56' and 72' boom trucks reach curtain wall panels from the exterior without interior scaffold or disruption to tenants. We coordinate work sequencing with property managers to avoid conflict with business hours, loading docks, and high-traffic entry areas. For Gates of Prosper retail tenants — where every day of disrupted storefront access costs revenue — our self-performing crew model keeps the job moving without subcontractor coordination delays.

Commercial Caulking & Sealant
Perimeter sealants at curtain wall heads, sills, and jambs fail independently of wet seals. We address both systems together to eliminate every moisture entry point in a single mobilization.
Learn more about our sealant services →Commercial Waterproofing
Curtain wall repair handles the glazing system; waterproofing protects adjacent masonry and concrete. Combining both scopes in one mobilization reduces cost and prevents redundant staging on the same facade.
See our waterproofing capabilities →Exterior Building Repair
Cracked concrete sills, spalled masonry at curtain wall perimeters, and damaged aluminum framing need structural repair before new sealants can hold long-term. We perform both scopes with one crew.
