Expert Stucco Repair for Arizona Homes

Professional Stucco Repair for Phoenix Homes

Stucco is the exterior finish of choice for the vast majority of Phoenix-area homes, and for good reason - it’s durable, attractive, and well-suited to the desert climate. But no stucco exterior is immune to the effects of time, heat, and Arizona’s unique environmental conditions. Cracks develop, patches crumble, and holes appear from impacts, plumbing penetrations, and settling foundations.

At John Claude Painting, stucco repair is a natural extension of our exterior painting services. In fact, we believe that quality stucco repair is the essential first step before any exterior painting project. Painting over damaged stucco is a waste of money - the cracks and imperfections show through almost immediately. That’s why we offer comprehensive stucco repair services that restore your walls to like-new condition before a single coat of paint is applied.

Understanding Why Stucco Cracks in Arizona

Arizona’s climate puts extraordinary stress on stucco exteriors. During summer, surface temperatures on south-facing and west-facing walls can exceed 150 degrees. At night, those same walls cool by 70 degrees or more. This daily thermal cycling causes stucco to expand and contract, and over years, this movement creates hairline cracks that gradually widen.

Monsoon season adds another layer of stress. Sudden torrential rain can drive moisture into existing cracks, and when the desert sun bakes it dry again, the rapid moisture cycling accelerates deterioration. Soil settling - common in newer Phoenix subdivisions - can also cause foundation movement that transfers stress to stucco walls, creating larger structural cracks.

Types of Stucco Damage We Repair

Hairline Cracks: The most common type of stucco damage in Phoenix. These fine cracks are typically caused by thermal cycling and normal settling. While they may seem minor, they allow moisture penetration and should be repaired before painting.

Structural Cracks: Wider cracks that may indicate foundation movement, structural settling, or improper original installation. These require deeper repair that addresses the underlying substrate, not just a surface patch.

Holes and Impact Damage: From wayward baseballs to plumbing repairs to solar panel installations, holes in stucco are common. We rebuild these areas from the substrate outward, matching both the thickness and texture of the surrounding wall.

Water Damage: When moisture penetrates behind stucco, it can cause bubbling, crumbling, and delamination. We remove all compromised material, address the moisture source, and rebuild the stucco layers properly.

Expansion Joint Failures: The caulked joints between stucco sections eventually dry out and crack in Arizona’s heat. We remove old caulk and re-seal these joints with flexible, UV-resistant sealant.

Our Texture Matching Process

The hallmark of a great stucco repair is invisibility. When the work is done, you shouldn’t be able to tell where the repair was made. Our texture matching process involves carefully studying the existing stucco pattern - its depth, spacing, and application technique - and replicating it by hand. We work with the full range of Arizona stucco textures including smooth finish, sand float, dash coat, lace, and skip trowel.

Stucco Repair Before Painting

We strongly recommend addressing all stucco damage before any exterior painting project. Our combined repair-and-paint approach saves you money compared to hiring separate contractors, and it ensures that your new paint job goes onto a smooth, sound surface that will hold up for years. Every exterior painting estimate we provide includes a thorough stucco assessment with repair recommendations.
