If your stucco is cracking, bulging, or letting water in, stucco remediation is the fix, not another patch. Superior Stucco St. Louis finds the cause, removes failed material, repairs the wall assembly, and rebuilds durable stucco that matches your finish, serving St. Louis since 2018.
Stucco remediation starts with controlled demolition and proper prep so repairs bond and stay put. We protect landscaping and adjacent finishes, then open up the affected areas to inspect the substrate, sheathing, and framing, and to locate the water pathway around windows, doors, decks, and roof-to-wall transitions. From there we remove loose or delaminated stucco, address rusted lath and damaged WRB, and rebuild the base using code-appropriate layers, galvanized expanded metal lath, proper fasteners, and scratch-and-brown coats mixed to spec. We use straightedges, screeds, and moisture checks to confirm flatness and drying before moving to finish work.
St. Louis freeze-thaw cycles and wind-driven rain punish weak details, so our remediation focuses on drainage, flashing, and vapor management as much as the surface coat. We integrate kickout flashing where needed, add weep screed at terminations when the assembly allows, and tie in WRB and self-adhered flashing to create continuous shingle-lap drainage planes. For the finish, we match existing texture and color as closely as possible, including acrylic finish coats, traditional cement stucco, and elastomeric coatings when specified for additional flexibility. Final blending includes proper curing time, sealant joints at dissimilar materials, and clean, straight termination lines so the repair does not telegraph through.
Customers choose us because we treat stucco remediation like building science, not cosmetics. You get a clear scope, photos of findings, and straightforward options based on the wall type (hard coat stucco over lath, stucco over masonry, or EIFS-style systems). Our crews work with proven materials like polymer-modified base coats, fiberglass mesh where required, corrosion-resistant lath, and high-quality sealants, and we keep the job organized with dust control and daily cleanup. Superior Stucco St. Louis is licensed and insured, and since 2018 we have focused on doing the unglamorous details correctly, flashing, drainage, and base preparation that prevent repeat failures.
At the end of the project we walk the site with you and verify that transitions, edges, and penetrations are sealed and properly detailed. You receive a written estimate up front, a documented scope, and a finished surface that is sound, uniform, and ready for paint when applicable after cure time. We also outline basic maintenance, including when to recaulk joints, how to manage sprinkler overspray, and what early warning signs to watch for so small issues do not become full remediation again. If you are comparing bids, we will explain exactly what is being removed and rebuilt so you can confirm you are getting real stucco remediation, not a thin skim coat over a failing base.
Yes. We provide a free written estimate that outlines the scope, materials, and the recommended repair or replacement approach.
Yes. We repair and install traditional cement stucco and EIFS systems, using compatible base coats, mesh, accessories, and finish coats for the existing assembly.
Temperature and moisture matter for curing and adhesion. We schedule work around conditions and use appropriate protection so base coats and finishes cure correctly and avoid washout or freezing.
Frequent causes include missing or incorrect flashings, poor WRB laps, buried weep screeds, inadequate lath fastening, lack of control joints, and sealant failure around penetrations and openings.
Small patches may take 1-2 days plus cure time, while larger remediation or full replacements take longer due to demo, substrate repairs, multiple coats, and drying time between steps.
Stucco remediation is the process of removing failed stucco and repairing the wall assembly so the system can drain, dry, and perform long term. If you see cracking, staining, soft spots, or bulging, the cause is often trapped moisture, missing flashing, deteriorated lath, or movement at control joints. Superior Stucco St. Louis focuses on diagnosing the failure, rebuilding the base correctly, and matching the finish so the repair looks clean and holds up in local weather.
Many “repairs” fail because they only treat the surface. True stucco remediation addresses what is behind the finish coat: water intrusion points, compromised sheathing, deteriorated paper or housewrap, corroded lath, and missing or incorrect terminations. Our process typically includes selective removal, inspection of the substrate, replacement of damaged components, and reconstruction of the stucco base with proper thickness and reinforcement where needed. We also pay close attention to joints and transitions, including sealant compatibility and backer rod installation, so movement does not reopen cracks.
Because St. Louis sees hot summers, heavy rain, and freeze-thaw cycles, the details matter. We integrate flashing at roof-to-wall intersections, verify drainage at the bottom edge, and correct grade and hardscape contact that can wick moisture into the stucco. When the existing finish is painted, we evaluate breathability and recommend coatings that do not trap moisture. For older homes, we can also coordinate repairs around brick, stone, and wood trim so the assembly sheds water the way it should.
If you are dealing with recurring cracks, leaks, or bubbling paint, schedule a site visit. We provide a free written estimate, explain what we find in plain language, and outline the scope so you know exactly what is being rebuilt. The goal is a stable base, a properly detailed water-resistive barrier and flashing tie-in, and a finish that blends in, without repeating the same failure in the next season.
