Phoenix Stucco Repair Pros — Free Estimates & Fast Scheduling

Phoenix's climate and soil conditions create specific challenges for stucco. The intense year-round UV bakes the finish coat, causing older stucco to chalk, fade, and lose flexibility. The daily and seasonal thermal cycling, with swings from 110F-plus summer highs to cool winter nights, constantly expands and contracts stucco, opening hairline cracks at window corners and control joints. The July-through-September monsoon drives wind-blown rain and dust against west- and south-facing walls, leading to moisture intrusion through these cracks. Furthermore, much of the Valley sits on caliche, which can hold moisture against footings, or has pockets of expansive clay that swell and shrink, or alluvial desert soils with low cohesion, all of which transmit stress into stucco as diagonal, stair-step, or corner cracking. Our services address these issues using a Portland cement-lime three-coat stucco system applied over galvanized metal lath with two layers of grade-D building paper. We sound walls to map delaminated areas, cut failed stucco back to a sound edge, and lap fresh metal lath and building paper shingle-style. We hand-apply scratch, brown, and finish coats, moist-curing them to prevent shrinkage cracking, and match existing textures like dash, sand-float, or skip-trowel on a sample board. We re-cut control joints on the original grid and reset foundation weep screeds so water drains out. Penetrations and joints are sealed with closed-cell backer rod and masonry-grade polyurethane sealant. For EIFS walls, we use an EIFS moisture probe meter for surveying trapped water and re-survey after repair to confirm drying. Minor stucco patching is generally treated as ordinary repair, but installing, repairing, or replacing an EIFS system or repairing exterior wall waterproofing requires a permit through the Planning and Development Department, and many HOA communities require architectural approval for re-stucco or color changes.
