Stucco structural problems can be caused by a wide variety of factors, including man-made disturbances, weather issues, and natural wear and tear. Understanding the root causes of these problems is crucial in finding effective solutions to maintain the integrity and appearance of your stucco exterior.
1. Foundation Settlement
One of the most common causes of stucco structural problems is foundation settlement. When the soil beneath the house compresses or is washed away by floods or heavy rainstorms, it can lead to foundation settlement. This can cause vertical cracks in foundation walls and exterior stucco, as well as uneven floors doors, and windows that no longer fit properly. To address foundation settlement, it may be necessary to stabilize the soil using techniques such as underpinning or soil grouting.
2. Water Infiltration
Water infiltration is another major culprit behind stucco structural problems. If water permeates the home’s structure (such as through excessive water around the home’s foundation), it can gradually deteriorate the lath and other material behind the stucco, resulting in cracks, mold growth, and even structural damage. To prevent water infiltration, it’s important to ensure proper drainage around the home, seal any cracks or gaps in the stucco, and regularly inspect and maintain the exterior.
3. Weather Circumstances
While stucco is considered a weather-repellent siding, it is not immune to the effects of extreme weather conditions. Wind, heavy rains, and humidity can weaken the material over time, leading to cracks, flaking, and other types of damage. To mitigate the impact of weather on stucco, it’s essential to use high-quality materials and ensure proper installation techniques are followed.
4. Vibrations
The external vibrations from nearby construction sites or heavy traffic can also lead to cracks in stucco siding. These vibrations can cause the stucco to separate from the underlying lath or substrate, resulting in visible cracks and damage. In some cases, it may be necessary to reinforce the stucco with additional lath or mesh to prevent this type of damage.
Addressing Stucco Structural Problems
If you notice any signs of structural problems in your stucco exterior, it’s important to address them promptly to prevent further damage and costly repairs. This may involve repairing cracks, sealing gaps, or even replacing sections of the stucco. In some cases, it may be necessary to consult with a professional stucco contractor or structural engineer to determine the best course of action.
By understanding the common causes of stucco structural problems and taking proactive steps to maintain and protect your exterior, you can help ensure the longevity and beauty of your home’s stucco siding for years to come.
