EXTERIOR BUILDING
REPAIR & RESTORATION
IN PLANO, TX.
Plano's Legacy District contains buildings where Frito-Lay's 1985 campus and the former J.C. Penney HQ (1.8M sq ft, early 1990s) have seen original sealant and waterproofing systems exceed their designed service life by a decade. AT&T's $1.35B global HQ announcement resets the competitive baseline — aging envelopes need to perform at Class A standards to hold Class A tenants.
What Exterior Building Repair Includes
Comprehensive facade repair for commercial buildings — from concrete patching to full cladding restoration.
Concrete Repair & Patching
Spall repair, crack injection, and structural concrete restoration for walls, columns, beams, lintels, and parking deck surfaces. On Plano's 30-40 year old Legacy District campus buildings, concrete spalling is typically driven by rebar corrosion — we remove all deteriorated material to sound substrate, treat exposed steel, and apply engineered repair mortars rated for the structural loads and exposure conditions.
Parking deck concrete repair is a specialty within this scope: traffic-bearing slabs require repair mortars with rapid-strength development to minimize traffic lane closures, and deck drains and transitions must be addressed as part of any spall repair to prevent recurrence.
Masonry & Brick Repair
Tuckpointing, brick replacement, lintel repair, and mortar joint restoration for commercial masonry facades. Legacy District buildings from the mid-1980s through early 1990s used brick veneer extensively — and 30-40 years of North Texas weathering has eroded original mortar joints to the point where water infiltration is active in many cases.
We match mortar color, joint profile, and brick dimensions precisely — critical on corporate campus buildings where tenant-facing aesthetics are held to Class A standards. Brick tie inspection is included in all masonry repair scopes for buildings past 25 years.
Stucco & EIFS Repair
Crack repair, delamination correction, and moisture barrier restoration for synthetic and traditional stucco. EIFS systems installed in Plano's 1990s commercial buildings have exceeded designed service life — base coat cracking, failed drainage planes, and deteriorated sealants at penetrations are common building-wide conditions on these structures, not isolated defects.
Plano's May 2024 hail event ($2.3B+ in regional damage) and June 2023 storms ($7-10B insured losses) punched through EIFS finish coats on thousands of commercial buildings. We probe and scan before scoping — not every breach is visible, and patching only what's visible leaves active infiltration points behind.
Metal & Panel Cladding Repair
Corrosion treatment, panel replacement, fastener restoration, and joint re-sealing for metal panel, ACM, and composite systems. Plano's Class A towers and corporate headquarters — including the Toyota North American HQ's seven-building campus — use metal panel and composite cladding that requires systematic joint inspection and sealant replacement on 10-15 year cycles.
We re-seal panel joints with commercial-grade sealants to manufacturer specifications, replace corroded or backed-out fasteners, and treat any corrosion at panel edges before it migrates behind the cladding assembly.

Why Plano Buildings Need Exterior Repair Now
The Legacy Business District — started by Ross Perot in the early 1980s and now spanning 2,665 acres — contains North Texas's most concentrated portfolio of large corporate campuses. Frito-Lay's 300-acre, 556,000-sq-ft facility joined Legacy in 1985. The former J.C. Penney HQ opened its 1.9M-sq-ft complex in 1992. These buildings are 30-40 years old, and original sealant systems, waterproofing membranes, and curtain wall glazing compounds installed at construction have long exceeded their designed service life of 20-25 years.
AT&T's January 2026 announcement of a $1.35B global HQ at 5400 Legacy Drive — targeting up to 10,000 employees — combined with the $1B redevelopment of the J.C. Penney campus into The Park at Legacy, is reshaping the competitive landscape for every other building in the district. Owners of 1990s-era Class A buildings that have not maintained their exterior envelopes are now competing against actively repositioned properties. The window to repair proactively — before a full restoration scope is required — is closing.

Exterior Building Repair FAQ
What types of exterior building damage require professional repair?
Plano's Legacy Business District — spanning 2,665 acres with buildings dating from Frito-Lay's 1985 arrival through the early 2000s — is in the damage window where original sealant systems, waterproofing membranes, and curtain wall glazing compounds have exceeded their 20-25 year designed service life. The most common issues we assess on Legacy District buildings are failed expansion joint sealants at precast panel connections, deteriorated glazing compounds in curtain wall systems, concrete spalling at column bases and parking deck edges, and masonry joint erosion at the older campus buildings. On the former J.C. Penney HQ (1.8M sq ft, built early 1990s, now undergoing $1B redevelopment) and comparable complexes, sealant failure and concrete deterioration are often building-wide conditions rather than isolated defects.
How do you determine if exterior damage is structural or cosmetic?
For Plano's Class A office towers and corporate campuses, we use a systematic approach combining visual facade mapping, sounding and probing of suspected delamination areas, moisture probing at joints and penetrations, and in some cases thermal imaging to locate water infiltration behind cladding. Plano's hail record is severe: May 2024 caused $2.3B in regional damage, June 2023 storms caused $7-10B in insured losses. Post-storm facade assessments on glass curtain wall buildings regularly reveal failed glazing sealants that appear intact under casual inspection but are no longer weathertight. The high density of curtain wall buildings in Legacy West and Granite Park makes systematic post-storm envelope inspection an annual operating expense — not a one-time event.
Can exterior repairs be done while the building remains occupied?
Yes — Plano's corporate campuses operate at full capacity, and major tenants like Toyota (4,000+ employees), the incoming AT&T global HQ, and Frito-Lay cannot pause operations for facade work. We use our 56' and 72' boom trucks to access multi-story facades without scaffolding that would block parking structures and pedestrian entries. For high-rise towers in Legacy West and Granite Park requiring higher access, we coordinate swing stage and rope access approaches where boom equipment is not sufficient. Work is sequenced by building elevation to maintain entry access throughout the project, with daily safety briefings coordinated with facility management.
What is the typical scope of a commercial exterior building repair project?
For Plano's large corporate campus buildings, a typical scope begins with a full building envelope survey — elevation by elevation, noting all crack locations, joint failures, sealant conditions, and substrate defects. For a campus like Frito-Lay's 300-acre, 556,000-sq-ft facility (now 40 years in service), that survey generates a prioritized repair matrix organized by water infiltration risk and structural significance. Immediate action items typically include failed expansion joints, open curtain wall sealants, and active concrete spalls with exposed rebar. Deferred items include hairline cracks and cosmetic masonry joint erosion without active infiltration. For multi-building campuses, we provide building-by-building scope documents to support phased capital planning against annual maintenance budgets.
How does deferred exterior maintenance affect a building's value?
AT&T's announced $1.35B global HQ at 5400 Legacy Drive — targeting up to 10,000 employees — will reset the competitive baseline for the entire Legacy corridor. The former J.C. Penney HQ's $1B redevelopment into The Park at Legacy creates the same pressure on adjacent buildings. 1990s-era Class A buildings that haven't maintained their exterior envelopes will face a stark leasing comparison against refurbished Class A space. Facade condition is the most visible signal to prospective tenants of how a building is managed. Buildings with visible concrete spalling, stained masonry, and failed sealants will lose tenant quality and be forced into larger, more expensive restoration scopes when they're finally repositioned — rather than the routine maintenance programs that would have avoided the compounding.
