Stucco water damage rarely stays cosmetic, it can wick behind the finish and rot wood, rust lath, and swell sheathing. Superior Stucco San Antonio has served San Antonio since 2016, delivering targeted stucco water damage repair that stops the leak path and restores a clean, durable finish.
We start by confirming the source and extent of the stucco water damage, not just the stain line. After protecting landscaping and masking windows, we remove loose or delaminated stucco back to sound material and expose the drainage plane as needed. Repairs typically include replacing damaged wood or OSB sheathing, installing new Grade D building paper or a rainscreen-style WRB, and re-lathing with galvanized expanded metal lath, fastened to framing. We rebuild the base with a scratch coat and brown coat using polymer-modified stucco, embed alkali-resistant fiberglass mesh at transitions and crack-prone areas, and set proper control joints so movement does not reopen the repair.
Local conditions matter because intense sun, wind-driven rain, and quick dry-out cycles can hide moisture pathways until the next storm. We correct common entry points like failed sealant at window flanges, poorly integrated kick-out flashing, missing weep screed, and incorrect terminations at rooflines and decks. For the finish, we match the existing texture (smooth, sand float, lace, or dash) and blend color using acrylic finish coat, elastomeric coating, or a paint system rated for masonry, depending on what the wall needs. Curing time, coat thickness, and moisture management are handled to ASTM-style best practices for cement plaster so the patch does not telegraph or craze.
San Antonio customers choose us because we fix stucco water damage at the assembly level, not with surface caulk and paint. You get a clear scope, a written estimate, and repair options based on what we find behind the wall, including selective demo versus full elevation repair when necessary. Our crews work with professional mixing, trowel and hawk application, proper fasteners, and dust control so the job stays clean and consistent. We coordinate with window, gutter, and roofing trades when a flashing or penetration detail is the real cause, and we document the repair steps so you know what was corrected.
At the end, we walk the repaired areas with you and confirm that terminations, sealant joints, and drainage details are properly integrated. You receive the repaired substrate and stucco coats, a texture and color match plan, and guidance on cure times and when to wash or paint. We also point out maintenance items that prevent repeat damage, like keeping soil and mulch below the weep line, maintaining caulk joints, and directing downspouts away from the wall. If we uncover related issues such as cracking at control joints or prior improper patching, we explain the options and pricing before any added work proceeds.
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.
Stucco water damage can start as hairline cracking or a small stain, then turn into bubbling paint, soft spots, moldy odors, and interior drywall damage. The key is to find the water entry point, remove compromised material, restore the drainage plane, and rebuild the cement plaster system so it sheds water and dries correctly. Superior Stucco San Antonio focuses on repair methods that address the full wall assembly, including flashing details, lath attachment, base-coat thickness, and finish compatibility.
Common causes of stucco water damage include missing or blocked weep screed, improper window and door integration, failed sealant joints, roof-to-wall intersections without kick-out flashing, and penetrations that were never properly sealed. Water can travel behind the finish coat and saturate the paper and lath, leading to rust staining, swelling at fasteners, and loss of bond between coats. Our process focuses on identifying those pathways and correcting the detail, then rebuilding the stucco layers so water drains and the wall can dry.
A proper stucco water damage repair often involves replacing deteriorated sheathing or framing, installing new Grade D paper or an equivalent WRB, re-lathing with galvanized metal lath, and reapplying scratch and brown coats with attention to keying, thickness, and cure. We reinforce transitions with alkali-resistant mesh and use compatible finish materials, such as acrylic finish coat, elastomeric coating, or a masonry paint system where appropriate. The goal is a repair that blends in visually and performs long term.
If you suspect stucco water damage, early action limits demolition and lowers total cost. We provide a straightforward inspection, explain what is failing and why, and deliver a written plan to restore both appearance and moisture performance.
