CURTAIN WALL
REPAIR & SERVICES
IN DENISON, TX.
Denison won the 2025 Great American Main Street Award — recognizing three decades of sustained downtown revitalization across a 30-block commercial core where 710 buildings have been rehabilitated with $74 million in reinvestment. With a median year built of 1967, Denison's storefront glazing and curtain wall systems on those rehabilitated buildings are now serving some of the most complex masonry-to-glazing interfaces in North Texas.
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 Denison's downtown Commercial Historic Overlay District, wet seal replacement at storefront glazing frames requires sealant color-matched to adjacent masonry mortar and compatible with the historic brick substrate — not standard commercial gray silicone. The D3 Phase 2 streetscape investment ($23 million, under construction since May 2024) raises the visible standard for private property maintenance on adjacent buildings.
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.
North Texas expansive clay soils throughout the Denison area generate pressures exceeding 10,000 lbs/sq-ft on foundations — cyclical movement that propagates to glazing frame anchor connections and displaces pressure-plate alignment over the decades. For Denison's nearly 60-year-old median commercial stock, gasket compression loss is often cumulative rather than sudden.
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.
Ruiz Foods' 315,000-sq-ft Denison plant — expanded from 250,000 sq ft with $30 million invested in 2022 — cannot have undiagnosed water infiltration compromising food production areas. ASTM E1105 testing isolates whether infiltration is occurring at the building envelope or through roof-to-wall transitions on a mid-century industrial structure expanded across multiple construction phases.
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.
Denison's population grew 11.6% since 2020 and the downtown has added 164 net new businesses. Property owners rehabilitating aging commercial buildings under the Texas Main Street Program receive technical assistance that includes facade standards — damaged or hail-impacted spandrel panels on recently rehabilitated buildings undercut the investment made in masonry and structural restoration.

Why Denison's Revitalized Downtown Needs Curtain Wall Expertise
Denison is a historic railroad city on the Texas-Oklahoma border that has sustained 36 years of Main Street Program investment — 710 buildings rehabilitated, $74 million reinvested, 164 net new businesses, and the 2025 Great American Main Street Award as the national recognition. The 30-block Commercial Historic Overlay District and its 200+ independently owned businesses represent a commercial real estate market where facade condition is a primary business investment, not a deferred maintenance line item.
Designing Downtown Denison Phase 2 — $23 million approved, construction began May 6, 2024, described as the most ambitious infrastructure renovation in the city's 152-year history — is injecting public investment into streetscapes, utilities, and public spaces throughout the historic core. Private building owners whose storefront glazing and curtain wall systems are leaking or visibly deteriorated are now directly adjacent to this public investment.
Griffin Restoration is headquartered in Whitesboro — 18 miles west of Denison — and works regularly throughout Grayson County. We understand the specific masonry substrates, historic overlay requirements, and industrial-scale building challenges in this market.

Curtain Wall Repair FAQ
What causes curtain wall systems to fail on commercial buildings?
Curtain wall failure originates in sealant degradation, gasket compression loss, and anchor movement. In Denison — winner of the 2025 Great American Main Street Award with a median commercial year built of 1967 — most of the city's building stock predates modern curtain wall engineering standards entirely. The 30-block Commercial Historic Overlay District contains storefront glazing systems retrofitted into 100-year-old masonry over multiple decades, each retrofit generation layering new glazing materials over aged masonry substrates. North Texas expansive clay soils generate pressures exceeding 10,000 lbs/sq-ft on foundations, creating cyclical stress on every frame-to-masonry anchor. The June 2023 DFW-region storms produced insured hail losses of $7-10 billion — the most costly hail season on record — with older brick downtown buildings especially vulnerable to spalling and mortar joint erosion that destabilizes adjacent glazing frames.
How do you diagnose leaks in a curtain wall system?
We use AAMA 511 and ASTM E1105 water testing protocols to locate leak sources before any repair work. Denison's downtown Commercial Historic Overlay District presents the most complex diagnostic environment in the region: 710 rehabilitated buildings where storefront and curtain wall glazing systems are integrated with masonry dating to the 1880s-1910s. Spray bar testing with sequential masking distinguishes whether water is entering at a glazing perimeter seal, the frame-to-masonry transition joint, or through the masonry substrate itself — a critical distinction since each requires a different repair approach. For Ruiz Foods' 315,000-sq-ft Denison plant at 2410 Texoma Drive, industrial-scale water testing documents envelope performance across a building expanded multiple times since 2005.
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 North Texas weather exposure. In Denison's downtown Historic Overlay District — where $74 million in public and private reinvestment since 1988 has rehabilitated 710 buildings and added 164 net new businesses — wet seal repair on storefront glazing must be coordinated with historically appropriate masonry sealant selection at the frame-to-brick transition. The Texas Main Street Program and Designing Downtown Denison (D3) Phase 2 ($23 million, under construction since May 2024) create a public-investment environment where private facade maintenance is both expected and competitively necessary.
How often should curtain wall sealants be inspected?
Annual visual inspection and a professional assessment every 3-5 years. In Denison, with a median commercial year built of 1967, many storefront glazing systems are operating on second- or third-generation sealants installed over poorly prepared original substrates — a condition where adhesion can fail without obvious surface deterioration. Inspect after every significant hail event: the June 2023 DFW-region storm season produced $7-10 billion in insured losses, and Denison's older brick buildings are especially vulnerable to surface spalling and mortar joint erosion that opens adjacent glazing frame anchors to water. For Ruiz Foods' industrial plant — where $30 million was invested in 2022 — annual envelope inspection is proportionate to the asset value and operational continuity risk.
Can curtain wall repairs be done on occupied high-rise buildings?
Yes — and Denison's commercial buildings are predominantly low-rise, making access coordination more straightforward than major metropolitan high-rise work. Ruiz Foods' 315,000-sq-ft plant operates with approximately 1,100 employees and cannot halt production for exterior repairs. We use our 56' and 72' boom trucks for exterior access without scaffolding and stage work bays sequentially, maintaining envelope security at all times during sealant replacement. For downtown Denison's occupied storefronts — over 200 independently owned businesses in the Commercial Historic Overlay District — we coordinate work during off-peak hours when needed and provide temporary weather protection for any open joints during multi-day repair sequences.
