CURTAIN WALL
REPAIR & SERVICES
IN ALLEN, TX.
Allen's corporate office corridor — including the 475,000-sq-ft One Bethany campus and Watters Creek's 170,000 sq ft of Class A space — was built mostly between 2003 and 2020. That first wave of curtain wall construction is now reaching its initial sealant replacement cycle, and Collin County's expansive Blackland Prairie clay accelerates joint movement at every anchor point.
What Curtain Wall Repair Includes
Systematic repair for glass and metal curtain wall systems — from perimeter sealant replacement to panel swap-outs.
Wet Seal Replacement
Remove failed perimeter sealant from glass-to-frame and frame-to-structure joints. Clean substrates and apply compatible structural silicone or urethane sealants rated for the system's movement and exposure.
On Allen's Class A office buildings where tenant satisfaction is paramount, we stage wet seal work floor-by-floor using our boom trucks — maintaining building operations and minimizing the window any single elevation is open to weather.
Gasket & Dry Glazing Repair
Replace deteriorated EPDM, silicone, or neoprene gaskets in pressure-plate and structural glazing systems. Includes compression testing and alignment verification to restore the original weather seal.
Allen's Collin County clay soils generate cyclical movement at curtain wall anchor points, compressing gaskets unevenly over time. Gasket inspection after hail events — like the $300-$400 million May 2023 storm — is essential to catch impact-induced misalignment before it causes water intrusion.
Leak Investigation & Diagnosis
Systematic water testing per AAMA 511/ASTM E1105 to locate leak paths. We isolate individual components — sealant, gaskets, weeps, frame joints — to identify the actual failure before recommending repairs.
Many curtain wall leaks in Allen's 2000s-era buildings are misdiagnosed: water appearing at the third floor may enter at the fifth. Proper spray bar testing with sequential masking identifies the true entry point, keeping repair costs proportionate to actual damage.
Panel & Infill Replacement
Replace damaged, discolored, or delaminated spandrel glass, insulated units, and metal infill panels. We source compatible units and coordinate installation to maintain visual consistency.
With a 225,000-sq-ft Class A tower under construction at One Bethany North, existing buildings on the Watters Creek corridor face direct visual competition. Replacing delaminated spandrel units or cracked insulated glass is a straightforward investment in tenant retention against newer inventory.

Why Allen's Curtain Wall Buildings Need Attention Now
Allen is a mature, high-income DFW suburb with a developed corporate office corridor anchored by financial services, technology, and data analytics firms. One Bethany at Watters Creek — 475,000 sq ft of Class A office space across two buildings completed in 2018 and 2020 — represents the scale of glazed commercial construction that defines the market.
Allen's median year built of 2003 means the earliest commercial buildings are entering the 25-35 year maintenance inflection point where original curtain wall sealants, gaskets, and wet seals fail simultaneously. Collin County's expansive Blackland Prairie clay — covering over 60% of the land area — puts continuous cyclical stress on every frame-to-structure anchor connection.
With One Bethany North (225,000 sq ft, $100M+) under development and Watters Creek anchoring 7+ million annual visitors through Allen Premium Outlets, the visible bar for curtain wall condition on established buildings has never been higher.

Curtain Wall Repair FAQ
What causes curtain wall systems to fail on commercial buildings?
The primary failure modes are sealant degradation, gasket compression loss, and anchor movement. In Allen, the most relevant driver is Collin County's Blackland Prairie clay — soils that swell up to 12% in volume and generate pressures exceeding 10,000 lbs/sq-ft on foundations. That cumulative cycling stresses curtain wall anchor connections and frame joints over 20+ years. Allen's commercial buildings are mostly 2000s construction, meaning the original EIFS cladding, caulk, and concrete spandrel sealants are now 20-30 years old — squarely in the window when first-generation systems fail. Add 2-3 annual hail events from North Texas's severe weather corridor and you have accelerated perimeter sealant damage on top of the structural movement issues.
How do you diagnose leaks in a curtain wall system?
We follow AAMA 511 and ASTM E1105 water testing protocols to isolate leak sources systematically. On Allen's Class A office buildings — such as the One Bethany campus (475,000 sq ft across two towers) — it's essential to test each component independently: perimeter wet seals, pressure-plate gaskets, weep slots, and frame-to-structure anchors. Spray bar testing lets us identify whether water is entering at a glass-to-frame joint or traveling from a higher source and emerging lower. We document findings before touching any existing material, so the repair scope is defensible and doesn't over-correct.
What is wet seal repair for curtain wall systems?
Wet seal repair removes the silicone or urethane sealant applied at the glass-to-frame and frame-to-structure perimeter joints and replaces it with a compatible structural sealant rated for the system's movement and UV exposure. On Allen's high-visibility corporate campus buildings — where tenants like Experian and NETSCOUT Systems occupy premium space — original wet seals installed in 2017-2020 are approaching their first replacement cycle. Proper wet seal work requires substrate cleaning with a primer compatible with the new sealant, correct joint geometry (2:1 width-to-depth ratio), and a sealant formulated for the specific movement class of the curtain wall system.
How often should curtain wall sealants be inspected?
We recommend visual inspection annually and a professional condition assessment every 3-5 years. In Allen's severe weather environment, inspect immediately after any significant hail event. The May 19, 2023 Collin County hailstorm caused an estimated $300-$400 million in damage (Insurance Council of Texas) — even buildings that didn't sustain visible glass breakage often have compromised perimeter sealant from the impact energy. Catching failed sealant early prevents water infiltration into insulated glass unit cavities, which destroys thermal performance and requires full panel replacement rather than a simpler sealant repair.
Can curtain wall repairs be done on occupied high-rise buildings?
Yes — and it's the standard scenario on Allen's office buildings. The One Bethany campus (East opened 2018, West opened 2020, North under development at 225,000 sq ft) and other Watters Creek corridor towers are fully tenanted. We sequence work floor-by-floor using our 56' and 72' boom trucks for exterior access, with interior protection where needed. Work is coordinated with building management to avoid impact on lobby areas and tenant-facing spaces. For pressure-sensitive work like sealant cure periods, we schedule around weather windows rather than interrupting building operations.
