Read on to learn more about identifying and repairing stucco cracks!

Understanding Stucco

Before we can address stucco cracks, it’s essential to understand what stucco is. Stucco is a type of plaster made from cement, sand, lime, and water. It’s applied in several layers over a metal lath attached to the walls of a house, offering an appealing aesthetic, durability, and natural resistance to fire and pests. However, like any other building material, stucco isn’t invincible and may crack under certain circumstances.

Types of Stucco Cracks

Stucco cracks come in various forms, each with a unique set of implications. Identifying the type of crack on your stucco can give you an insight into the severity of the situation and the potential remedies:

  1. Hairline Cracks: These are thin cracks less than 1/16 of an inch wide. Often, hairline cracks are a normal result of the stucco drying and shrinking over time. Though they’re not a severe concern, they should not be ignored because they can allow water seepage, causing damage over time.
  2. Pattern Cracks or Spider Cracks: These are a network of fine cracks, somewhat resembling a spider’s web. They’re usually a sign of a poorly done stucco job, where the stucco mix might have been wrong, or it dried too fast.
  3. Shrinkage Cracks: These are typically bigger and more irregular than hairline cracks and are usually due to the stucco mixture not having enough time to dry properly. While not immediately serious, they can become larger and more noticeable over time if left untreated.
  4. Structural Cracks: These are the most serious type of stucco cracks. They are typically wider than 1/8 of an inch and can stretch across a large part of a wall. Structural cracks may indicate issues with the foundation or structure of the house itself, requiring immediate professional attention.

Causes of Stucco Cracks

Several factors can contribute to the formation of stucco cracks. Some common ones include:

  1. Improper Installation: If stucco isn’t applied correctly, it can lead to several issues, including cracking. This is why it’s crucial to hire a reputable contractor like Old Pueblo Stucco L.L.C.
  2. Extreme Weather Conditions: Extreme heat or cold, strong winds, and heavy rain can cause stucco to crack.
  3. House Settling: As a house settles over time, it can cause movement in the walls, leading to cracks in the stucco.
  4. Impact Damage: Objects hitting the wall, like a stray ball or hail, can cause cracks or chips in the stucco.

Crucial Signs: What Homeowners Should Be Mindful Of With Stucco Cracks

As a homeowner, staying on top of the health and integrity of your stucco finish can be a significant part of maintaining your property. Stucco cracks, in particular, should not be overlooked. Here are key things homeowners should be especially mindful of:

  1. The Size of the Crack: The width of a stucco crack can be a telltale sign of its severity. Hairline cracks are generally less serious than larger, structural cracks that are over 1/8 of an inch wide.
  2. The Location: Stucco cracks that appear near the corners of doors and windows, or along the foundation of the house, can often signal more serious underlying structural issues.
  3. The Pattern of Cracks: If your stucco is displaying a pattern of fine, interconnected cracks, this could be an indication of a poor stucco job. This ‘spider web’ of cracks can often be a result of a poor stucco mix or the mixture drying too quickly.
  4. The Number of Cracks: Multiple cracks appearing concurrently on your stucco might indicate a more serious issue. While a single crack could just be due to weather conditions or minor impact damage, multiple cracks might suggest problems with the house’s foundation or stucco installation.
  5. Changes Over Time: Homeowners should regularly monitor the condition of their stucco, noting any changes in the size, shape, or number of cracks. If a crack grows in size over time or new cracks develop, it could indicate ongoing structural movements that need to be addressed by a professional.

In essence, stucco cracks should never be brushed aside as a mere cosmetic issue. If you spot one, it’s worth taking the time to examine it closely. And when in doubt, it’s always wise to consult a professional for advice.
