Stucco, with its classic look and robust nature, is a favored choice for home exteriors in Florida. Yet, one of the common issues homeowners face is cracking stucco. This blog will delve into why stucco cracks, explore the connection between these cracks and foundation settling, and discuss when repairs are necessary, highlighting why you should turn to professionals like Camrock Foundations for expert intervention.
Why Does Stucco Crack?
Natural Properties of Stucco: Stucco is essentially a mix of Portland cement, sand, lime, and water. As it dries, it undergoes natural shrinkage, which can lead to hairline cracks. In Florida’s climate, with its daily temperature fluctuations and high humidity, these cracks can become more pronounced.
Environmental Factors: The Sunshine State is known for its weather extremes – from scorching summers to torrential rains and hurricanes. These conditions can cause stucco to expand and contract, leading to stress and eventual cracking.
Settling of the Home: As a home settles into its foundation, which is quite common in the first few years after construction, the stucco can crack due to the movement. This settling is influenced by the ground beneath, which in Florida can be quite varied, from sandy to loamy soils.
Moisture and Soil Movement: Florida’s soil often experiences significant moisture changes. When soil gets wet, it can expand, pushing against the home’s foundation, and when it dries, it contracts, creating voids. This movement can stress the foundation, leading to cracks that might reflect on the stucco.
Installation Issues: Poor application, like not allowing enough time for each layer of stucco to cure, using an improper mix, or failing to install expansion joints, can also contribute to cracking.
Is Stucco Cracking Due to Foundation Settling?
Absolutely, there’s often a direct link between stucco cracks and foundation issues:
- Differential Settlement: If one part of your home’s foundation settles more than another, it can cause diagonal or stair-step cracks in your stucco, indicating uneven settling.
- Foundation Heaving: In contrast, if the soil beneath expands due to moisture, it can heave the foundation, which might show up as horizontal cracks or bulges in the stucco.
- Lateral Pressure: Poor drainage around the foundation can lead to soil erosion, causing the foundation to move sideways, which can stress the stucco in ways that result in cracks.
When Does Stucco Need Repair?
Cosmetic vs. Structural Cracks:
- Cosmetic Cracks: Small, hairline cracks below 1/16 inch typically do not need immediate repair unless they’re growing or allowing water penetration. However, they should be monitored.
- Structural Cracks: Wider cracks, those over 1/8 inch, especially if they’re diagonal, stair-step, or show signs of movement (like edges not aligning), are red flags for structural issues. These need professional attention.
Signs You Need Professional Repair:
- Cracks Reappearing: If cracks reappear after being filled, this suggests ongoing movement, likely from the foundation.
- Water Damage: Any sign of moisture intrusion through cracks is a call for immediate action.
- Doors and Windows: If doors or windows are sticking or showing gaps, it could be due to the foundation shifting, affecting the stucco.
- Cracks in Multiple Areas: Especially if they’re around window sills, doors, or at corners, it’s time to assess the foundation.
