If your stucco siding is cracking, bulging, or staining, the fix starts below the surface, not with a quick patch. Superior Stucco St. Louis has served St. Louis since 2018, installing and repairing stucco siding with proper drainage, reinforcement, and durable finishes.
Good stucco siding performance depends on prep and the base coat system. We start by evaluating the substrate (wood sheathing, masonry, or existing stucco), then correct framing issues, loose sections, and rot before new work begins. For new installations we install a code-appropriate weather-resistive barrier, corrosion-resistant flashing at windows, doors, and terminations, and metal lath with proper fasteners and laps; repairs may include selective lath replacement and controlled demolition back to sound material. We protect openings, set control joints where needed, and mix cement plaster to consistent ratios so the scratch and brown coats cure evenly and stay bonded.
St. Louis weather brings freeze-thaw cycles, wind-driven rain, and humid summers, all of which punish stucco siding that lacks drainage and flexibility. We build in water management with proper kick-out flashing, weep screeds at the base, and clean transitions to brick, stone, siding, and soffits, then allow correct cure time between coats to reduce shrinkage cracking. Finish options include traditional hard-coat cement stucco, acrylic finish coats, and elastomeric coating systems when a breathable, crack-bridging top layer is the right fit. Texture and appearance are matched to the home or building, including sand, lace, dash, smooth, and custom blends, with careful color consistency and edge detailing.
Customers choose us because we treat stucco siding like an exterior wall system, not a cosmetic surface. Our crew focuses on the details that prevent call-backs: straight screeds, plumb corners, reinforced stress points, properly sealed penetrations, and clean, tight terminations at trim and masonry. You get clear recommendations based on what we see on-site, whether that is a targeted repair, a recoat, or a full removal and replacement when the base is failing. We are licensed and insured, and we provide a free written estimate with scope that spells out materials, prep, and finish so you can compare bids apples to apples.
At completion, we walk the job with you and document what was repaired or installed, including drainage and flashing tie-ins that are usually hidden once the stucco siding is finished. You receive a clean site, protected landscaping, and a clear maintenance plan, including what to seal, what to avoid (like trapping moisture with the wrong paint), and what early warning signs to watch for. If the project includes patching, we blend texture and color as tightly as conditions allow and explain any natural variation from sun exposure and existing coatings. The goal is a stucco siding exterior that looks uniform up close and performs through heavy rain, heat, and winter freezes.

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.
