Stucco is a beautiful finish that can enhance the curb appeal of your home. However, stucco damage often requires major repairs that can be expensive.

Fortunately, homeowners can save money by repairing stucco damage when it occurs. Contact the professionals at Stucco Repair Philadelphia PA.

Hairline cracks in the stucco usually result from settling, while wider cracks can indicate structural problems. Cracks can be repaired by cleaning the damaged area, applying a bonding agent, and filling the crack with stucco mix.

Cracks in stucco are an unsightly and sometimes serious problem that can lead to moisture damage, mold, mildew and insect infestation. They can also weaken the structure of your home, causing it to shift and settle unevenly over time, potentially creating dangerous structural problems that should be addressed immediately.

While cracks in stucco are common and inevitable, they are not necessarily a cause for concern for every homeowner. It is important to determine the severity of the cracks before starting repairs, as larger cracks may indicate more significant issues and require professional assistance. Hairline cracks that are less than 1/16 inch wide are typically cosmetic and often result from minor settling and slight shifts in the building structure. Larger cracks, on the other hand, are more likely to be caused by structural shifts or severe weather conditions and should be repaired immediately to prevent further damage.

To repair small cracks, first clean the area and remove any loose debris using a wire brush. Then, apply a bonding agent to the edges of the crack. Next, fill the crack with stucco patching compound and use a trowel to smooth the surface and ensure that it blends with the surrounding stucco texture. Finally, smooth a second layer over the patch and use a texturing tool to match the existing stucco texture. After the repair is dry, mist the surface with water periodically to help it retain its elasticity and avoid further cracking.

It is best to do hairline crack repairs in the morning, when homes are cooler. This will make it easier to spot the cracks and fill them in without overdoing it. It is also best to use a high-quality water-based caulking as this allows the area to expand and contract with temperature changes without causing further damage.

Spider cracks are another common issue that is often mistaken for a structural problem. They appear as multiple vertical and horizontal lines that form a grid pattern on the surface of the stucco. This type of cracking is often caused by lath that hasn’t been nailed properly or is rotting, which creates stress on the stucco. In most cases, these cracks can be fixed by using a skim coat over the affected areas and then applying a new base coat over it.

Stains

Stucco is not impervious to stains, and it is important to be vigilant in identifying stains and taking action. Whether they are a result of water damage or simply a sign that the stucco has been exposed to the elements for too long, stains on your home’s stucco can lead to significant problems if left untreated.

One of the most common stains on stucco comes from dirt. This is often the result of debris kicked up in rainstorms or from people walking around the house. This type of stain is usually fairly easy to remove, and can be accomplished with a soft bristle brush or scrub brush along with regular detergent or stucco cleaner.

Another common type of stain is mold or mildew. This is often caused by a buildup of algae or other organisms that feed on the limestone in the stucco. These organisms tend to grow best in warm and damp conditions, and their presence often indicates a deeper moisture problem. If the mold or mildew is not killed and washed out, it will return and continue to cause a discoloration on the stucco.

Rust stains are also common on stucco. This may be the result of a rusty metal grate, vent, or gutter that is contacting the stucco. It may also be a sign that the underlying materials used to secure the EIFS are deteriorating and causing water intrusion.

When cleaning your stucco, be sure to test your cleaning solution on a less visible section of the wall first. This will allow you to see if the cleaner is effective, without damaging the surface. Once you’ve determined the cleaning solution is effective, wet down the lower sections of your stucco wall before washing the top areas. This will help prevent the dirty water that runs down the walls from above from absorbing into the stucco and causing additional damage.

In addition to addressing stains, be sure to address any chipping or cracking in the stucco before beginning a cleaning process. Small chips and cracks can be repaired with a bit of color-matched exterior acrylic caulk, but major damage should always be addressed by a professional who is familiar with stucco repair.

Harsh Weather Conditions

If your stucco is exposed to harsh weather conditions, it will likely wear down faster than it should. Extreme temperatures, moisture, and varying soils can all lead to damage. Fortunately, these issues can be repaired with regular maintenance and periodic inspections.

Water damage is one of the most common problems in stucco. Moisture can seep through cracks and erode the surface, causing discoloration and even mold growth. If left untreated, the damage can worsen and result in costly repairs.

Stucco is naturally porous and can absorb moisture, but this also causes it to deteriorate more quickly than other materials. This is especially true if there are areas of cracking or crumbling. If you notice any signs of water damage in your stucco, it’s important to take action right away.

One of the most obvious signs that your stucco needs repair is if you notice visible stains or different shades of color. This is usually a sign that there is water seepage behind the wall, which can be very dangerous for your home or building structure. It’s also a good idea to inspect the surrounding area for other signs of water damage, such as mold and mildew.

Another way to prevent water damage in your stucco is by ensuring that it has proper drainage. This means that any landscaping or flower beds should be far enough away from your stucco walls to avoid excess water build-up. If you have a sprinkler system, it’s essential that it is properly positioned to direct water away from the walls.

The harsh winter weather of Tucson can wreak havoc on stucco, causing it to crack and flake. This is usually due to the freeze-thaw cycle, where the stucco expands and then contracts as it freezes. If this happens repeatedly, it can lead to major cracks in the stucco, which can eventually lead to the complete failure of the material.

To prevent the damage, you can use a waterproof sealant to protect your stucco from moisture penetration and deterioration. Be sure to choose a waterproof sealant that is compatible with your existing concrete or stucco surface to ensure proper adhesion. Before sealing, be sure to clean the surface thoroughly to remove any dirt or debris that may interfere with the application of the sealant. Once it is dry, you can then apply a top coat of paint, stain, or varnish to protect the surface from moisture and further damage.

Remediation

When cracks in the stucco threaten to undermine the structure of your home, it’s time for remediation. Remediation is more involved than repair and involves addressing underlying issues that cause the damage. It can be costly but it provides a long-term solution that protects the structural integrity of your house and prevents future damage.

Isolated Cracks – If the cracks are isolated and do not seem to be spreading, repair is sufficient. Stains and Dark Spots – Musty smells, mold growth or discoloration around the windows or other fixtures are warning signs of a moisture problem behind the stucco. Bubbling or Blistering – This is a sign that water is trapped under the surface and can lead to serious problems down the road.

If you are unsure whether or not your stucco is in need of repair or remediation, a professional can perform a thorough inspection. They will check the integrity of the lath (the wooden slats that keep the stucco attached to the wall’s framework) and look for any evidence of water intrusion. The professionals will also check the insulation and sheathing for any signs of rot or moisture intrusion.

Once the professionals have inspected the stucco, they will decide if a repair or replacement is necessary. If the damage is severe, they will replace the damaged areas with new stucco and then the sheathing and insulation will be reinstalled. Then the new stucco will be applied and any final touches will be made.

If the experts do not find any moisture damage or rot on the sheathing, they may be able to simply repair the stucco and apply a fresh coat of paint. This will improve the overall appearance of your home and extend the life of your stucco.

Stucco is a beautiful and durable building material but it can be prone to cracking and other damages if the conditions are not favorable. Recognizing the warning signs of damage to your stucco and contacting a professional before the problems worsen will help you save money in the long run.
