Commercial · Salt Lake City, UT
Commercial leaks usually start where stucco meets joints, windows, and parapets, not in the field of the wall. Superior Stucco Salt Lake City has served since 2019, providing stucco waterproofing and leak repair that targets the water path and restores durable drainage, not just the finish coat.
We start with investigation and prep so repairs bond and stay watertight. After mapping moisture and entry points, we remove failed sealant, hollow delaminated areas, and loose base coat back to sound substrate, then clean and dry the work zone. From there we rebuild the system with corrosion-resistant lath as needed, code-appropriate weep screed and casing beads, and a compatible water-resistive barrier (Grade D building paper or a fluid-applied air and water barrier) shingled correctly with flashing. Base repairs are reinforced with alkali-resistant fiberglass mesh at cracks and transitions, using polymer-modified cement base coats and proper cure time before waterproofing layers and finishes go on.
Salt, freeze-thaw cycles, and big temperature swings can turn small sealant gaps into recurring leaks, so the finish details matter. We address common commercial weak points including window perimeters, control joints, expansion joints, parapet caps, balcony edges, scuppers, and stucco-to-EPDM or TPO roof transitions, tying in sheet metal or self-adhered flashing where appropriate. For stucco waterproofing, we select breathable coatings that shed bulk water while allowing vapor to escape, such as silane-siloxane penetrating water repellents, elastomeric wall coatings, and traffic-rated waterproof deck coatings on walkways and landings. Final texture matching is handled with traditional 3-coat stucco where needed, or acrylic finish coat systems when your building uses EIFS or an acrylic topcoat, keeping control joints, reveals, and terminations clean and functional.
Salt Lake City property managers and business owners choose us because we treat leak repair like a building-envelope scope, not a quick patch. Since 2019 we have focused on commercial stucco diagnostics, proper substrate prep, and details that prevent water from getting behind the assembly in the first place. Our crews work around operating businesses with clear staging, protection for storefronts and entries, and tidy daily clean-up, and we coordinate with roofing, glazing, and sheet-metal trades when the fix crosses scopes. You get a licensed and insured contractor who documents conditions, explains options in plain terms, and uses proven materials, correct fasteners, and manufacturer-approved sealants for long-term compatibility.
After repairs, we walk the building with you and verify that every transition is sealed, drained, and finished correctly. We check terminations at weep screeds, verify head flashing and end dams where accessible, confirm joint sealant depth and backer rod placement, and make sure scuppers, drip edges, and parapet details move water out and away. You receive a clear written scope, coating and sealant selections, texture and color matching notes, and maintenance guidance for joints and coatings to extend service life. If you need it, we can schedule periodic inspections to catch early cracking, coating wear, or sealant failure before leaks return.
Yes. We provide a free written estimate that outlines the recommended repair or installation method, finish, and timeline.
Yes. When damage extends past the finish, we can open the area, replace compromised sheathing or framing as needed, then rebuild the stucco or EIFS layers to spec.
We texture-match and color-match as closely as possible, but exact matches can be limited by sun fade and existing coatings. For highly visible areas, we may recommend blending a larger section or recoating an entire elevation.
Cure time depends on the system, thickness, and weather. Cement-based coats need time between lifts, and finish timing is planned around temperature and moisture so the surface hardens correctly.
Yes. We handle commercial, multi-family, and HOA stucco scopes, including phased repairs, consistent texture matching across elevations, and clear documentation for property managers.
Stucco waterproofing for commercial buildings is about controlling bulk water at penetrations and transitions while keeping the wall assembly able to dry. When leaks show up at storefronts, offices, warehouses, or multifamily exteriors, the cause is often failed sealant, missing flashing, cracked base coat, or water trapped behind an improperly lapped water-resistive barrier. Superior Stucco Salt Lake City focuses on finding the entry point, rebuilding the drainage and flashing details, and then restoring a durable, breathable finish.
Effective stucco waterproofing starts with the substrate. We remove compromised stucco down to sound material, then rebuild using corrosion-resistant lath and accessories, polymer-modified base coats, and alkali-resistant mesh where reinforcement is needed. At the assembly level we correct laps and terminations, integrate self-adhered or liquid flashing at openings, and verify that weep screeds and control joints are doing their jobs so incidental moisture can drain.
Coating selection depends on the wall type and exposure. For traditional cement stucco, silane-siloxane repellents can reduce absorption while preserving vapor permeability. Where bridging small cracks is required, elastomeric coatings are often the better fit, and traffic-rated deck coatings can protect walkways and balcony surfaces. We keep compatibility front and center so coatings, primers, and sealants work together instead of peeling or trapping moisture.
If you are dealing with recurring leaks, staining, blistering paint, or interior moisture around openings, schedule an on-site evaluation. We will provide a written plan that prioritizes the highest-risk details first, outlines prep and drying steps, and delivers a finish that looks consistent across repaired and existing areas while improving water shedding and long-term performance.
