The Popularity of Stucco

Stucco is a traditional building material that has been used for centuries, and its popularity continues to this day. 

It is a mixture of cement, sand, lime, and water that, when properly applied, creates a strong and attractive exterior finish. Stucco is known for its ability to resist fire, insects, and rot, making it a truly appealing choice for homeowners looking for a low-maintenance option.

The Risks of Stucco

While stucco offers many benefits, it is not without its risks, especially when it is not installed or maintained correctly. 

The primary issue with stucco homes is moisture infiltration, as when water finds its way behind the stucco facade, it can become trapped, leading to a host of problems:

Water Damage

Prolonged exposure to moisture can cause the underlying wood framing and sheathing to rot. This can weaken the structural integrity of the home and lead to costly repairs.

Mold and Mildew

Moisture trapped behind stucco can create the perfect environment for mold and mildew growth. Not only can this be a health hazard, but it can also damage the interior of your home.

Cracking and Peeling

Stucco that has absorbed moisture may develop cracks or begin to peel, compromising its appearance and protective qualities.

Insulation Issues

Water infiltration can reduce the insulation properties of your home, leading to higher energy bills as your heating and cooling systems work harder to maintain a comfortable indoor temperature.

Aesthetic Problems

Even if there are no structural issues, water damage can lead to unsightly stains and discoloration on the exterior of your home, reducing its curb appeal.

Assessing Stucco Damage

Detecting stucco damage early is crucial to prevent further issues and reduce repair costs. Here are some steps to assess the damage:

Visual Inspection

Begin with a visual inspection of your home's exterior. Look for cracks, peeling paint, or stains on the stucco surface. Pay attention to areas around windows, doors, and rooflines, as these are common entry points for moisture.

Probe Testing

Use a screwdriver or a similar tool to gently probe the stucco in suspicious areas. If the stucco feels soft, crumbles easily, or you can push the tool into the surface, it may be a sign of underlying moisture damage.

Moisture Testing

Moisture meters can be used to measure the moisture content of the stucco. High moisture levels in the stucco may indicate a problem. It's essential to test various areas of the home's exterior to get a comprehensive assessment.

Interior Inspection

Check the interior of your home for signs of any water damage, like mold growth, musty odor or water stains, as these can be indicators of moisture infiltration from the exterior.

Professional Inspection

When in doubt or if you suspect damage, it's wise to consult a professional stucco contractor. They have the tools and expertise to assess the extent of the damage accurately and properly repair it.

Stucco Remediation Options

If you've determined that your stucco-clad home has suffered damage, it's very important to promptly address the issue. Stucco remediation options vary depending on the severity of the damage:


In some cases, minor damage can be repaired by patching and reapplying stucco in the affected areas. This is a cost-effective solution for small issues.

Partial Remediation

If the damage is more extensive but limited to specific areas, you may opt for partial remediation. This involves removing and replacing the damaged stucco sections while leaving the unaffected portions intact.

Full Remediation

In severe cases of water damage or widespread issues, a full stucco remediation may be necessary. This involves completely removing the existing stucco, addressing any underlying structural problems, and applying a new stucco system correctly.

Improved Drainage

It's essential to improve the drainage and moisture management around your home in order to prevent future damage. This may involve installing proper flashing, sealants, and other moisture-resistant barriers.

Alternative Exteriors

If stucco remediation is not feasible or cost-effective, you may consider alternative exterior options, such as vinyl siding, brick, or stone veneer.

Choosing a Qualified Contractor

Regardless of the remediation option you select, you’ll need to work with a qualified contractor who specializes in stucco remediation. Here are some tips for choosing the right professional:

  • Experience: Look for contractors with a proven track record in stucco remediation. Ask for references and check their past projects.
  • Licensing and Insurance: Ensure the contractor is licensed, bonded, and insured to protect yourself in case of any unforeseen issues.
  • Warranty: Inquire about the warranty they offer on their work. A reputable contractor should provide a warranty that covers both materials and labor.
  • Detailed Estimate: Get a detailed written estimate that outlines all the work to be done, the materials to be used, and the cost breakdown.
  • Communication: Choose a contractor who communicates effectively and is responsive to your questions and concerns throughout the remediation process.

Whether you opt for repairs, partial remediation, or full stucco remediation, working with a qualified contractor is key to ensuring the job is done correctly.
