CURTAIN WALL
REPAIR & SERVICES
IN ANNA, TX.
Anna's Anna Business Park — anchored by HOLT CAT's 79,000-sq-ft facility on an 82-acre campus — is planned for 3M+ sq ft of industrial development at build-out. New construction on Collin County's reactive Blackland Prairie clay means curtain wall and storefront glazing joints begin experiencing movement stress almost immediately after commissioning.
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.
In Anna's industrial corridor, metal panel-to-curtain wall transition joints are a common failure point. We specify sealants rated for the differential thermal movement between aluminum framing and adjacent metal panel systems — a different requirement than standard masonry caulking.
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.
Anna's Collin County clay generates lateral soil movement that transfers through foundations to curtain wall anchor channels, displacing pressure-plate alignment over time. Gasket compression testing after foundation movement events is essential to maintaining the original weather performance spec.
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.
New construction in Anna's rapidly developing US-75 corridor can present early curtain wall leaks from installation deficiencies rather than age-related degradation. Proper ASTM E1105 testing distinguishes between a failed sealant joint and a misaligned weep slot — two different repairs at very different costs.
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.
Anna's industrial and commercial buildings compete for DFW industrial spillover tenants arriving from McKinney and Allen. Damaged or discolored panels on office and showroom facades — visible to tenants evaluating competing properties — directly affect leasing decisions on Anna Business Park buildings.

Why Anna's Growing Building Stock Needs Curtain Wall Expertise
Anna is rapidly industrializing through its US-75 and Collin County Outer Loop position. The Anna Business Park — 85 acres at SH-5 and the Outer Loop — is planned for 3 million square feet of total industrial development at build-out. HOLT CAT's 79,000-sq-ft facility, which opened in 2022 as the company's 12th North Texas location, is the anchor, but remaining acreage is in active development.
Since 2019, Anna has added 100+ new businesses, 500+ jobs, and finalized agreements representing over $3 billion in commercial and residential investment. Every new shell building or commercial storefront represents a near-term curtain wall and envelope maintenance contract as structures settle on Blackland Prairie clay.
Collin County ranked second among all U.S. counties for net population gain from July 2024 to July 2025, adding 42,966 residents. That growth pressure translates directly to commercial construction that needs proper envelope protection from day one.

Curtain Wall Repair FAQ
What causes curtain wall systems to fail on commercial buildings?
Curtain wall failure traces to three root causes: sealant degradation, gasket compression loss, and frame movement from substrate shifting. In Anna, the most significant driver is Blackland Prairie clay soil — North Texas clay soils can swell up to 12% in volume and generate pressures exceeding 10,000 lbs/sq-ft on foundations during wet-dry cycles. That cumulative movement stresses every frame-to-structure anchor over time. Anna's rapid development (population nearly doubled since 2020) means new industrial and commercial buildings with curtain wall or storefront glazing are going up in reactive soil conditions without the benefit of long-term settlement data. Industrial buildings like HOLT CAT's 79,000-sq-ft facility also accumulate differential movement from heavy equipment vibration that stresses perimeter sealant joints.
How do you diagnose leaks in a curtain wall system?
We use AAMA 511 and ASTM E1105 water testing to locate leak sources methodically. In Anna's newer industrial and commercial buildings, leak paths are often counterintuitive — water entering at a high glazing joint may travel inside the frame system and emerge at a weep slot two stories down. We mask and spray-test individual bays, working from the bottom up, to isolate whether the failure is in the wet seal, gasket compression, weep drainage, or frame-to-structure anchor joint. For large-footprint buildings like the Anna Business Park industrial users, this systematic approach prevents over-repair of unaffected bays and keeps scope focused on verified failure locations.
What is wet seal repair for curtain wall systems?
Wet seal repair removes deteriorated perimeter sealant at glass-to-frame and frame-to-structure joints and replaces it with structural silicone or urethane sealant rated for the system's movement class and UV exposure. In Anna's industrial corridor, buildings using aluminum storefront or commercial curtain wall systems need sealants compatible with the thermal movement of metal-panel adjacent construction — not the same formulation used on masonry facades. We evaluate the original sealant spec, substrate condition, and joint geometry before specifying a replacement, ensuring the new seal is rated for the joint's actual movement range rather than a generic substitution.
How often should curtain wall sealants be inspected?
Annual visual inspection and a professional assessment every 3-5 years is standard. For new construction in Anna — where rapid building on reactive Collin County clay soils means early joint movement is common — we recommend a baseline assessment at 2-3 years to catch any sealant adhesion failures before they cause water infiltration. Anna sits in North Texas's severe weather corridor with 2-3 annual hail events tracking up US-75 from Dallas. Industrial buildings with large metal panel facades and standing-seam roof interfaces at curtain wall systems are especially vulnerable to hail damage at the transition joints.
Can curtain wall repairs be done on occupied high-rise buildings?
Yes — and occupied operation is the norm. Anna's commercial buildings are lower-rise than major office towers, but HOLT CAT's active 8-bay service facility, Anna Business Park industrial users, and retail buildings along US-75 are all operational during business hours. We use our 56' and 72' boom trucks for exterior access and schedule sealant cure windows around weather and operational needs. For industrial tenants, we coordinate with facility managers to protect machinery and product from water exposure during any temporary opening of seals being replaced. Work can typically be staged so no single elevation is fully open at once.
