Cracked and Bulging Stucco - Signs of Foundation Problems?

Cracked and bulging stucco can be signs of foundation problems, as they may indicate that the foundation is shifting or settling. When a foundation shifts, it can cause the stucco on the exterior of a building to crack and bulge. This can happen if the foundation is not properly supported or is affected by soil movement or water damage.

It is important to address foundation issues promptly, as they can lead to more serious structural problems if left untreated. If you notice cracked or bulging stucco on your property, call Professional Foundation Repair in Garden Grove to assess the situation and determine the best action to address any underlying foundation issues.

Causes of Stucco Cracks - When to Worry

Various factors can cause stucco to crack or bulge, including foundation settlement, water damage, deterioration of the stucco mix, or seismic activity. It's crucial to pay attention to these signs as they could signify structural problems with the foundation of your property. Stucco cracks may start small but can worsen over time if left untreated. Hairline cracks are thin and may not seem severe initially However, they can grow into larger cracks if the underlying issue is not resolved, emphasizing that cracks can be caused by various factors not immediately visible. Stucco foam trim cracks often occur around doors and windows and should be inspected to prevent further damage to the stucco or plaster siding.

Stucco Bulges and Their Causes

Homeowners in Southern California may frequently encounter stucco bulges, which can be a prevalent problem, especially for those with older homes. Professional Foundation Repair's experts can help identify the underlying cause, which might be foundation damage, rot in the wood frame, improperly installed stucco, or seismic activity. Recognizing the symptoms of foundation issues early on can help prevent larger problems. If you notice bulges around your window and door frames, it may be time to consider a stucco repair job before the damage becomes more severe.
During stucco installation, the mud stucco must adhere properly to the foundation wall. A good foundation is essential to maintaining the integrity of your home. Without a solid type of foundation, the framework for the mud stucco can become compromised, leading to bulges and other issues.

Different Types of Stucco Cracks

Stucco Hairline Cracks & Cross-Patterned Cracks

Hairline cracks may resemble fine lines on the surface of the stucco. These are very thin cracks that are typically less than 1/16 of an inch in width. They can often be caused by normal settling and drying of the stucco, as well as temperature changes. However, while they may seem minor, these cracks can indicate underlying issues that need attention to prevent further damage to the stucco and the structure.

Stucco Foam Trim Cracks

Foam trim cracks are commonly found around doors and windows where the stucco meets the trim. These cracks can allow water to seep in, causing more significant damage to the stucco and potentially to the frame of the door or window. These do not necessarily indicate foundation problems, but left untreated, the home's water barrier can become compromised, leading to foundation problems that require significant repair.

Cross-patterned cracks in stucco can indicate that the foundation may be settling unevenly or that there is a structural issue causing the stucco to crack in a specific pattern. They are usually wider and more severe than hairline cracks. A professional should assess these cracks to identify the root cause. Ignoring these cracks can lead to further damage to the structure of the building over time. It is important to address the issue promptly to prevent further damage and potentially costly repairs in the future. The experts at Professional Foundation Repair can assess the situation, identify the root cause of the cracking, and provide recommendations for proper repairs to ensure the stability and safety of the building, including the application of plaster where necessary. 

Stucco Spider Cracks

Spider cracks in stucco, named for their web-like appearance, can indicate the stucco is pulling away from the underlying structure. Tiny fractures in stucco can result from shifting foundations, fluctuations in temperature, or water damage. If left untreated, these cracks can allow moisture to seep into the underlying structure, leading to more serious issues such as mold growth or structural damage.

In some cases, it may be necessary to consult a professional stucco contractor or an expert like Professional Foundation Repair to assess the extent of the damage and determine the best course of action for repair. Our experts can evaluate and address any underlying issues causing the cracks, such as poor drainage or inadequate support.

Stucco Diagonal Line Cracks

Diagonal line cracks form at an angle across the stucco surface. It's crucial to address diagonal cracks promptly to prevent them from worsening, as these are often clear signs and symptoms of foundation problems. Further, these cracks can allow water to seep into the stucco, causing more damage and potential mold growth. If left untreated, the structural integrity of the stucco can be compromised, leading to more extensive and expensive repairs.

To address diagonal line cracks in stucco, consult with our structural engineering specialists at Professional Foundation Repair or a professional stucco repair specialist to assess the cause of the cracks and determine the best course of action. Depending on the underlying issue, repairs may involve reapplying stucco, installing control joints, addressing foundation issues by recognizing the signs and symptoms of foundation damage or improving drainage around the home.

Stucco Corner Cracks

These cracks typically occur at the corners of the building where stress is concentrated. They are often caused by settling, shifting, or poor installation techniques. To fix corner cracks in a building, it is important to first determine the root cause of the problem. If settling or shifting is the cause, it may be necessary to address underlying foundation issues. This is where Professional Foundation Repair's experts can be of assistance.

If poor installation techniques are to blame, the cracks may need to be repaired by filling them with an appropriate sealant or patching material. In some cases, it may be necessary to reinforce the corners of the building to prevent further cracking. It is important to address corner cracks promptly, as they can lead to further structural damage if left unchecked.
