With over 35 years of experience under our belts, we know precisely what it takes to make your exterior stucco siding look beautiful again. Whether you need parging or a major stucco repair, we’ve got you covered!

Common Stucco Siding Issues

Despite stucco siding’s high durability, it’s not immune to issues. Fortunately, most problems can be easily fixed if caught early. Let’s look at several typical problems that homeowners might encounter with their exterior stucco siding:

1. Cracking
Cracks are the most common problem with stucco houses. They can be as small as hairline flaws or as big as big holes. Anything from house moving and earthquakes to temperature changes and impact damage can result in these cracks. If you don’t fix them, water can get in and cause structural damage.

2. Efflorescence
Efflorescence is a white, powdery material on the surface of stucco. It happens when water gets into the stucco and dissolves the salts in it. When the water evaporates, it leaves these salts on the surface. Aside from being visually unappealing, efflorescence can also be a tell-tale sign of a larger moisture problem.

3. Staining
Stucco’s porous nature makes it susceptible to staining. From mildew and mould to dirt and rust, various elements can cause discolouration.

4. Bulging or Bubbling
Bulging or bubbling of the stucco surface often indicates that water has seeped beneath the stucco, causing the underlying material to warp. This issue suggests that the stucco siding was not correctly installed, leading to detachment from the underlying surface.

Addressing Stucco Siding Issues

Understanding these challenges is a key step. It’s also critical to know how to address and prevent these issues to maintain the beauty and integrity of your stucco siding.

1. Regular Inspections

Routine visual inspections can help you spot any budding issues before they escalate. Check for cracks, staining, efflorescence, or bulging. If you witness any damage, it’s advisable to address it immediately or seek professional guidance.

2. Prompt Repairs

Small hairline cracks can typically be filled with a high-quality caulk that matches your stucco colours. Larger cracks, bulging, efflorescence, or persistent staining may require the services of a professional stucco repair company.

3. Prevention

You can prevent many stucco issues with proper maintenance. This might include regular cleaning with a power washer in a gentle setting to remove dirt and inhibit mildew growth. Furthermore, regular application of a waterproof sealant can help protect your stucco from water damage and staining.

How to Repair Exterior Stucco Hole

Step 1: Assess the Damage

Before making repairs, examine the extent of the damage. Small holes or cracks can be resolved using a patching compound. While larger ones may require reinforcement with mesh or metal lath. In some cases, you might need to replace whole sections of stucco.

Step 2: Gather Materials and Tools

  • A hammer and chisel
  • Stucco Repair Mesh or metal lath (if necessary)
  • Stucco patching compound
  • Paintbrush
  • Exterior paint that matches your siding

Step 3: Fixing the Hole

Small Holes and Cracks

With a small trowel or putty knife, apply the stucco patching compound, gently pushing it into the hole or crack. Smooth the compound to match the surrounding surface texture. Allow it to cure according to the manufacturer’s guidelines.

Larger Holes

For more substantial damage, follow these steps:

  • Chisel away: Use a hammer and chisel to remove damaged or loose stucco around the hole, creating a uniform edge.
  • Install mesh or metal lath: Attach mesh or metal lath inside the hole to provide a solid base for the new stucco.
  • Patch with stucco compound: Mix the stucco patching compound according to the package instructions. Apply the mixture over the lath, using a trowel or float, and press firmly for good adherence.
  • Cure the stucco: Allow the patch to dry, which could take several hours to a full day, depending on the size of the hole and weather conditions.
  • Apply a topcoat: Once the patched area has dried, apply a topcoat of the stucco patching compound. Use a trowel or float to match the texture of the surrounding stucco.


Step 4: Paint the Repaired Area

After the final coat has fully dried, you must paint the repaired area to match the rest of your exterior siding. Ensure you use stucco paint suitable for outdoor surfaces. Painting stucco can significantly enhance your home’s exterior, adding a fresh, vibrant look while providing a protective layer against weather damage and UV rays.


1. Why It’s Crucial to Parge and Repair Your Stucco Siding?

The Purpose of Parging

What is stucco parging? Parging is a method that involves applying a thin coat of a cement-like mixture to the surface of a wall, in this case, stucco siding. It serves multiple purposes:

  • • It’s an essential step in the installation of stucco siding, as it ensures a smooth and level surface for the stucco to adhere.
  • • It aids in protecting the exterior walls against moisture penetration, which can lead to a host of problems, including mould, mildew, and structural damage.
  • • Parging also enhances the aesthetic appeal of stucco siding by giving it a clean, uniform look.

Exterior Stucco Repair: Reasons to Act

Despite its reputation for durability, stucco siding isn’t indestructible. Regular wear and tear, exposure to the elements, and other incidents can lead to various issues that need prompt attention. Here’s why it’s crucial to address these problems and repair your exterior stucco siding:

1. Preventing Structural Damage

When stucco siding has cracks or breaks, water can get into the walls and cause problems like mould, mildew, and structural damage. By making fixes right away, you can stop these problems from getting worse and keep your home stable and safe.

2. Maintaining Aesthetic Appeal

A well-maintained stucco exterior can improve a home’s curb appeal. If you don’t make the necessary fixes, your property might get cracks, stains, or wear and tear that makes it look bad. By fixing problems right away, your stucco wall will keep its beautiful, smooth look.

3. Energy Efficiency

Stucco siding is a good insulator, so it helps keep your home cool when it’s hot and warm when it’s cold. If your stucco is damaged, it won’t insulate either, so your HVAC system must work harder to keep your home at a comfortable temperature. By fixing damaged stucco siding, you can make your house more energy efficient and save money on energy bills.

4. Protecting Your Investment

Your home is a significant investment, and maintaining its exterior is essential to preserving and, in some cases, enhancing its value. Timely stucco siding repairs maintain the structural integrity and aesthetic appeal of your home, ensuring a long-term return on investment.

5. Avoiding Costly Repairs

Attending to minor stucco siding issues early will save you time, money, and potential headaches in the future. Ignoring small problems can lead to more extensive damage, requiring costly repairs or even complete stucco replacement.

2. How Much Do Stucco Siding Parging and Repairs Cost?

The cost to paint stucco siding, parge, and repair it varies based on its size, the kind of wood used, and the extent of the damage.

But if you’re curious about what an exterior wood repair and carpentry might cost, here are some ballpark figures:

• Small handyman project: $1,500 to $3,000 + HST

• Medium handyman project: $3,000 to $5,000 + HST

• Large handyman project: $5,000 to $10,000 + HST

• XL handyman project: $10,000 to $20,000 + HST
