Commercial · San Antonio, TX
Water intrusion in commercial stucco usually starts at joints, penetrations, and failed sealant, then travels behind the cladding. Our team provides stucco waterproofing and leak repair for offices, retail, warehouses, and multifamily buildings in San Antonio, using methodical testing and durable detailing to stop repeat leaks.
Prep and base work decide whether a waterproofing repair lasts. We start by mapping stains, cracks, and soft areas, then verify moisture paths with a moisture meter and targeted hose testing around windows, parapets, and pipe penetrations. Loose or delaminated stucco is removed back to sound substrate, we correct sheathing or framing rot as needed, and we rebuild the base with proper lath, weep screed where applicable, and code-correct flashings. High-risk transitions get a fluid-applied air and water-resistive barrier tied into existing WRB, plus mesh-reinforced treatment at corners and seams to control movement.
South Texas heat, sudden downpours, and wind-driven rain punish commercial facades, especially at long wall runs and expansion joints. We detail control joints, kick-out diverters, and window perimeters so water sheds to the exterior instead of wicking into the assembly. Depending on the existing system, we match 3-coat hard coat stucco, acrylic finish coats, or EIFS-style finish textures, then apply breathable water repellents or elastomeric coatings where appropriate. Final work includes tooled and backer-rod sealant joints (urethane or silicone) at dissimilar materials, plus drip edges and termination bars to keep the top of the system dry.
San Antonio property owners and facility managers choose us because we treat stucco waterproofing as a building-envelope problem, not a quick patch. You get clear documentation, photos, and written scope before work starts, plus practical options that fit your budget and tenant schedule. We coordinate lift access with your site team, including scaffolding, boom lift, or swing stage as needed, and we keep the jobsite controlled with dust management and daily cleanup. As a licensed and insured contractor serving since 2016, we focus on durable details, consistent finish matching, and repairs that reduce ongoing maintenance calls.
Before closeout, we walk the building with you and verify repairs at the exact locations that leaked. We re-check moisture readings, perform controlled water testing where needed, and confirm sealant continuity at joints, terminations, and penetrations. You receive a free written estimate up front, a clearly defined repair plan, and a finish that blends with surrounding elevations so the facade looks intentional, not patched. If you have recurring issues, we can schedule periodic sealant and coating inspections to keep the stucco waterproofing system performing year after year.
Yes. We work on houses, multi-family buildings, offices, and retail properties, including repairs, re-stucco, texture work, and repainting.
Yes. We evaluate likely entry points, including sealant joints and flashing transitions, then rebuild damaged plaster and blend the finish to match.
We install traditional cement plaster stucco and compatible finish systems, including acrylic finishes and elastomeric coating systems when specified for the project.
Yes. We provide a free written estimate after an on-site evaluation so you have a clear scope, materials plan, and price.
We aim for a close blend by matching texture and then coating for uniform color. Exact invisibility depends on existing weathering, previous paint layers, and the original texture pattern.
Commercial stucco leaks rarely come from the field of the wall. They usually start at windows, parapets, expansion joints, storefront transitions, and roof-to-wall intersections where flashing, sealant, or the water-resistive barrier has failed. Superior Stucco San Antonio provides stucco waterproofing and leak repair that targets the source, rebuilds compromised areas, and restores proper drainage so water stays out of the wall assembly.
Our stucco waterproofing process begins with investigation, not guesswork. We document symptoms, trace water migration, and identify failure points such as missing kick-out flashing, failed head flashing, unsealed fasteners, or cracked control joints. Repairs typically include selective demolition, substrate correction, lath and base coat rebuild, and flashing or WRB integration so the assembly sheds water the way it was designed to.
For commercial properties, durability and repeatability matter. We use compatible materials, including galvanized lath, cement-based base coats, fiberglass mesh reinforcement at stress points, and breathable coatings or water repellents when the wall needs added protection without trapping moisture. Sealant joints are rebuilt with the correct joint width, backer rod depth, and commercial urethane or silicone where specified, because most “stucco leaks” are really joint failures.
If you manage multiple buildings or recurring maintenance tickets, we can help you standardize repairs and prevent future intrusion with scheduled inspections of sealants, terminations, and coatings. Request a free written estimate and we will outline the scope, access needs, and the most cost-effective path to long-term stucco waterproofing performance.
