EXTERIOR BUILDING
REPAIR & RESTORATION
IN DENTON, TX.
Denton's building stock spans 110 years — from Curry Hall (1912) on UNT's campus to late-1990s commercial construction on South Loop 288. The May 2024 hail event added urgency across the board. Whether it's historic masonry on the Denton Square or aging concrete at Peterbilt's 700,000-sq-ft plant, our crews repair the substrate correctly — not just the surface.
What Exterior Building Repair Includes
Structural and cosmetic exterior repair for commercial facilities — concrete, masonry, stucco, EIFS, and metal cladding systems.
Concrete Repair & Patching
Spall repair, crack injection, and structural concrete restoration for walls, columns, beams, and lintels. Remove deteriorated concrete to sound substrate, treat exposed rebar, and apply engineered repair mortars matched to the original mix.
For Denton's aging institutional and industrial stock — including structures at Peterbilt's 238-acre plant and UNT's century-old campus buildings — systematic concrete repair protects both structural integrity and code compliance.
Masonry & Brick Repair
Tuckpointing, brick replacement, lintel repair, and mortar joint restoration. Match mortar color, joint profile, and brick dimensions to maintain architectural character.
Denton's Downtown Historic District — 50 buildings with 30 designated as contributing resources — demands period-appropriate mortar mixes and joint profiles. Our crews understand the difference between historic lime mortars and modern Portland cement, and select formulations that won't accelerate brick spalling.
Stucco & EIFS Repair
Crack repair, delamination correction, and moisture barrier restoration for synthetic and traditional stucco systems. Address substrate damage that caused the failure, not just surface symptoms.
South Loop 288 commercial buildings from the late 1990s frequently present EIFS delamination driven by failed window perimeter sealants and inadequate flashing. We open the system, repair the substrate, replace flashing where needed, and close with properly textured and color-matched finish coats.
Metal & Panel Cladding Repair
Corrosion treatment, panel replacement, fastener restoration, and joint re-sealing for metal panel, ACM, and composite cladding systems. Includes structural attachment inspection.
Denton's industrial corridor — including facilities on the Enterprise Airport industrial area and Rayzor Ranch — uses metal panel systems requiring periodic fastener inspection and joint re-sealing. The 2024 hail event is an appropriate trigger for a full panel condition survey.

Why Denton Buildings Need Exterior Repair Now
UNT's 963-acre campus contains buildings spanning 110 years — from Curry Hall (1912) and the Power Plant (1915) through modern research facilities. Each era presents distinct repair challenges: historic soft brick requiring lime-compatible mortars, mid-century concrete subject to carbonation and rebar corrosion, and 1990s EIFS now showing its age at window terminations and expansion joints.
The 1896 Denton County Courthouse — Romanesque Revival with granite, sandstone, and limestone exterior — underwent masonry restoration in 1987 and again in 2004. The surrounding National Register Historic District contains 30 contributing buildings, most facing ongoing mortar joint deterioration driven by North Texas's expansive black clay soils and freeze-thaw cycling.
Denton's commercial median year built is 1997 — meaning a large share of retail and office construction on South Loop 288 is now 25-30 years old, squarely in the window for sealant replacement, spall repair, and facade inspection. The May 2024 hail event, which produced softball-sized hailstones and $2.3B in regional damage, added urgency for property owners who have yet to commission a post-storm assessment.

Exterior Building Repair FAQ
What types of exterior building damage require professional repair?
Commercial buildings in Denton face a wide range of damage: concrete spalling on university campus structures, mortar joint deterioration on the 1896 County Courthouse and surrounding historic buildings, stucco delamination on 1990s commercial construction along South Loop 288, and EIFS cracking on more recent developments. Professional repair is required when damage compromises the building envelope — allowing moisture infiltration — or when structural concrete is exposed. With UNT and TWU combined enrollment of 57,000 students, Denton's institutional portfolio demands prompt, code-compliant repair to protect long-term asset value.
How do you determine if exterior damage is structural or cosmetic?
We begin with a systematic visual survey combined with sounding (tapping) to identify delaminated concrete and hollow areas behind stucco or EIFS. Crack mapping documents width, pattern, and orientation — diagonal cracks signal differential settlement; horizontal cracks indicate lateral load issues. For Denton's older masonry buildings, we assess mortar joint depth and cohesion to determine if tuckpointing alone is sufficient or if lintel and shelf angle replacement is required. The May 2024 hail event that caused $2.3B in regional property damage also left many Denton buildings with impact damage requiring probe testing to distinguish surface from substrate failure.
Can exterior repairs be done while the building remains occupied?
Yes — occupied-building repair is the standard for Denton's commercial and institutional portfolio. We sequence work by elevation, use our 56' and 72' boom trucks to access upper floors without scaffolding, and schedule high-impact operations (pressure washing, grinding) during off-peak hours. For UNT and TWU campus work, we coordinate around class schedules and campus event calendars. For active retail on the Denton Square and South Loop 288 corridor, we maintain pedestrian access and signage visibility throughout the project.
What is the typical scope of a commercial exterior building repair project?
A typical Denton commercial project begins with a full-elevation condition assessment. Scope usually includes concrete spall repair to exposed rebar, mortar joint tuckpointing on brick and CMU facades, caulk joint replacement at expansion joints and window perimeters, and a protective coating or penetrating sealer. For historic buildings in the Downtown Denton Historic District — which has received over $132M in reinvestment since 1990 — scope must also satisfy Texas Historic Commission guidelines for material compatibility. Peterbilt's 700,000-sq-ft plant is an example of a large-footprint industrial envelope requiring phased, ongoing repair programs rather than a single project.
How does deferred exterior maintenance affect a building's value?
In Denton's competitive commercial market — where the Sally Beauty HQ relocation to Plano in 2025 created pressure on similar 2000s-era corporate buildings to demonstrate envelope integrity — deferred maintenance directly depresses lease rates and occupancy. Water infiltration through failed masonry or caulk joints damages interior finishes, creates mold liability, and triggers code compliance issues. Studies consistently show that exterior deterioration reduces appraised value by 10-15% and can disqualify properties from certain financing structures. For institutional buildings at UNT and TWU, deferred envelope maintenance also creates ADA and life-safety concerns at the facade level.
