When a stucco expansion joint fails, water gets behind the finish and cracks spread fast across the wall. Superior Stucco Henderson has served Henderson since 2017, repairing and replacing stucco expansion joints with proper sealants, lath tie-ins, and matching finishes.
We start by locating every control and expansion joint and checking adjacent cracking patterns, delamination, and moisture entry points around windows, doors, and rooflines. Loose stucco is sounded out and removed back to solid material, then the edges are squared for a clean patch. If the joint accessory is damaged or missing, we cut back to expose framing and sheathing as needed, install a new PVC or galvanized expansion joint (per the wall assembly), then rebuild the base with self-furring galvanized lath, corrosion-resistant fasteners, and a polymer-modified base coat over a properly integrated weather-resistive barrier and flashing details when accessible.
Henderson heat swings and intense sun beat up joint sealants, especially on south and west elevations where movement and UV exposure are highest. We set the joint width correctly, install backer rod to control sealant depth, then apply a high-performance elastomeric sealant with proper tooling for a concave profile and clean bond lines. After cure, we match the existing finish, including sand float, dash, lace, or smooth, and blend color when a tint coat or masonry coating is needed. The goal is a joint that moves as designed, sheds water, and does not telegraph a hard patch line through the finish.
Customers choose us because we repair the system, not just the crack. We look for the root cause, failed sealant, wrong joint placement, bridging with rigid patch material, or missing lath break, and correct it so the wall can expand and contract without tearing. Work is done with dust control, clean masking lines, and careful protection of windows, hardscape, and landscaping. You also get clear communication, documented options, and a scope that spells out materials like backer rod, compatible primers, and elastomeric sealants rather than vague promises.
Before we wrap up, we walk the project with you and verify joint continuity, sealant adhesion, and finish match from multiple viewing angles and lighting. We clean up all debris, remove masking, and leave the site ready for normal use the same day whenever possible. You receive a free written estimate up front, plus a straightforward plan for any related items we see, such as failed caulk at penetrations, stucco-to-trim transitions, or drainage at weep screeds. If additional cracking shows up elsewhere, we can map it, explain what is cosmetic versus water-related, and prioritize repairs to protect the building envelope.
We do both. We handle small patches and crack repairs, and we also take on full re-stucco and larger restoration projects when the existing system is failing or heavily patched.
In most cases, yes. We match common textures like sand-float, lace, skip-trowel, and dash by sampling and adjusting aggregate, trowel technique, and finish timing, then blending as needed.
Yes. We repair EIFS base coat and mesh, replace damaged foam shapes, and re-finish with compatible acrylic materials so the system performs as intended.
Small repairs can be completed in a day, but curing and finish blending can add time. Larger repairs or re-stucco projects depend on access, prep scope, and dry times between coats.
Yes. We provide a written estimate that outlines the repair method, materials, finish or coating, and any exclusions so you can make an informed decision.
A stucco expansion joint (often called a control joint) is there to manage movement and keep the stucco field from cracking randomly. When the joint accessory is bent, missing, or bridged with hard patch material, the wall loses that relief point and cracks open along stress lines. Superior Stucco Henderson repairs and replaces stucco expansion joints with the right accessories, backer rod, and elastomeric sealants so the assembly can move, shed water, and keep the finish looking consistent.
Most stucco expansion joint problems start with failed sealant, UV damage, or improper original installation. We inspect joint layout, look for missing breaks in lath, and check transitions at windows, doors, parapets, and dissimilar materials. When a joint needs replacement, we remove the surrounding stucco carefully, install the correct joint accessory, then rebuild the scratch and brown coats and re-texture to match the existing wall. When the accessory is sound, we can often restore performance by removing the old sealant, setting the correct backer rod, and applying a compatible, high-movement sealant with the proper depth-to-width ratio.
A lasting repair also depends on moisture control. If we see evidence of water entry, staining, or soft substrate, we address flashing laps, weep screed function, and damaged paper or housewrap where accessible, then tie the patch back in so drainage planes still work. We use proven materials, polymer-modified base coats, corrosion-resistant lath and fasteners, and primers when required for sealant adhesion on porous stucco.
If you are seeing straight-line cracking, separation at joint edges, or recurring cracks that reopen after patching, it is time to have the stucco expansion joint evaluated. Our process is built for practical results: identify the cause, repair the joint correctly, blend the finish, and leave you with a clear, written scope you can trust.
