Fix hairline, structural, and settlement cracks before they cause moisture damage. Free crack inspection for Van Nuys homes.
Cracks are the most common stucco problem in Van Nuys. The San Fernando Valley's extreme heat, dry climate, and soil movement create cracks in nearly every stucco home over time. The good news: most cracks are easy and affordable to repair if you catch them early.
We repair all types of stucco cracks on Van Nuys homes. From hairline surface cracks to structural cracks caused by foundation settlement. Every repair includes sealing to prevent moisture intrusion.
Hairline cracks are less than 1/16 inch wide. They are caused by normal thermal expansion and aging. In Van Nuys, hairline cracks appear on south and west-facing walls first because those walls get the most sun exposure. We fill hairline cracks with elastomeric caulk that stays flexible and moves with the stucco.
Structural cracks are wider than 1/8 inch and often run diagonally or in a stair-step pattern. They indicate movement in the wall or foundation. In Van Nuys, structural cracks are common in homes with clay soil that expands and contracts with moisture changes. We repair the crack and can refer you to a foundation specialist if needed.
Settlement cracks appear when the soil under your home shifts. Van Nuys has areas with expansive clay soil that moves seasonally. Settlement cracks typically appear near windows, doors, and corners. We repair the stucco and recommend drainage improvements to reduce future movement.
Thermal cracks form from repeated expansion and contraction. Van Nuys summer temperatures exceed 100°F, causing stucco to expand during the day and contract at night. Over years, this cycling creates cracks. We use flexible repair materials that accommodate thermal movement.

We measure every crack, check width and depth, and look for moisture behind the stucco.
We widen the crack into a V-groove so the repair material bonds properly.
We apply bonding agent, then fill with elastomeric caulk or stucco patch mix.
We texture to match and apply waterproof sealant to prevent future moisture intrusion.
