Water damage often starts at the bottom of the wall, where the stucco weep screed and flashing should drain and dry out the assembly. Superior Stucco St. Louis repairs failed screeds, base flashing, and stucco terminations to stop moisture intrusion and prevent recurring cracking in St. Louis homes and buildings.
We start by confirming how the wall is built and where the moisture path begins, typically at a buried or damaged stucco weep screed, missing kickout flashing, or a bad termination at a slab, stoop, or brick ledge. Our crew protects landscaping and hardscapes, then opens the stucco at the base with controlled cuts to expose the metal lath, paper or WRB, and the condition of the framing. We replace rusted or crushed screed with code-appropriate galvanized or stainless components, rebuild the drainage plane with Grade D building paper or a modern WRB, integrate self-adhered flashing tape at transitions, and re-lace new lath with corrosion-resistant fasteners before applying new scratch and brown coats at proper thickness.
St. Louis weather cycles push water into small gaps, then freeze-thaw expands cracks around the bottom edge, window legs, and deck or roof intersections. We correct common local failure points like stucco installed too close to grade, clogged weep holes, improper sealant joints, and base coats that bridge onto concrete and trap moisture. After repairs cure, we match your finish, including sand float, smooth trowel, lace texture, or dash, then blend color using acrylic finish coat or elastomeric coating when appropriate. Where movement is expected, we add properly tooled control joints, backer rod, and a high-performance polyurethane or STPE sealant at terminations so the wall can drain without relying on caulk alone.
Customers choose us because we treat stucco weep screed repair as a water-management job, not a cosmetic patch. We document the cause, explain the assembly in plain language, and show you what we find behind the wall before we close it back up. Crews use proven methods, clean tie-ins, and compatible materials so the repair does not create a hard spot that cracks later. You also get a straightforward scope, a free written estimate, and work performed by a licensed and insured stucco contractor focused on long-term performance.
Before final payment, we do a closing walkthrough and verify the details that keep the base dry: screed height above grade, clear drainage gaps, intact flashing laps, and clean weep paths. We check that finish texture and color blend from typical viewing distance, and we leave expansion joints and sealant lines neat and uniform. You receive a written scope of work, product notes on the flashing and sealants used, and care guidance for paint, irrigation, mulch height, and future caulking intervals. If you are chasing an active leak, we can also recommend targeted water testing and complementary repairs like kickout flashing, window head flashing integration, and small-area re-stucco where the system was interrupted.
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.
A stucco weep screed is the metal track at the bottom of a stucco wall that supports the plaster edge and allows trapped moisture to drain out. When it is buried by soil or mulch, rusted through, installed too tight to concrete, or disconnected from the water-resistive barrier (WRB), water can wick into framing, stain interior finishes, and cause base cracking and bulging. Superior Stucco St. Louis focuses on correcting the drainage path, rebuilding the base assembly, and restoring a clean, durable stucco termination.
Most stucco failures at the base trace back to missing or incorrect flashing details. We commonly see stucco run into the ground, no drainage gap above a slab, sealant packed into the screed, or paper and flashing that do not lap shingle-style. Our process is to open the wall only as much as needed, replace the damaged stucco weep screed, and integrate the WRB, self-adhered flashing, and metal lath so drainage works by gravity. If there is structural damage, we will flag it and coordinate with a carpenter before stucco is rebuilt.
After the base is corrected, we re-stucco with compatible materials and proper cure time, then finish to match your existing look. Repairs may include adding control joints, correcting sealant joints with backer rod, and addressing related transitions like brick-to-stucco, deck ledger areas, and roof-to-wall kickouts. The goal is a wall that sheds bulk water, drains incidental moisture, and dries out between storms.
If you suspect a buried screed, peeling paint at the bottom edge, interior staining, or recurring cracks along the foundation line, schedule an inspection. We will provide a clear plan, a free written estimate, and a repair scope that prioritizes drainage and flashing details, not temporary surface caulk.
