Why Stucco Repair Is Important

Small hairline cracks (a quarter-inch wide and below) in stucco can usually be patched with sanded acrylic caulk. This product comes in a variety of exterior colors that match most stucco. Read on Stucco Repair Philadelphia to learn more.

Stucco ServicesBefore patching, chisel loose stucco to widen the crack. Then, secure grade D building paper over the area to create a moisture barrier. Using tin snips, cut a piece of metal lath to fit the repair area.

Although stucco is one of the most durable materials used in building construction, it can still show signs of wear over time. While small cracks may seem like a minor cosmetic concern, larger ones should be addressed soon. Otherwise, they could deepen, resulting in lasting damage to the structure of your home.

Stucco is a porous material, which means it absorbs moisture and other elements from the environment. This can lead to unsightly dark spots, blistering, cracking, and mold. Proper maintenance can prevent these problems, including cleaning, sealing, and painting. Stucco should be sealed and repainted every 5 to 10 years, depending on the type of sealant used.

Hairline cracks are the most common type of problem for homeowners with stucco homes. These cracks are usually 1/8-inch or less in width and occur on the surface of the plaster. These can be filled with caulk or other masonry products to make them look smooth and new again. It is best to do these repairs in the morning when it is cooler, as this will help the caulk or masonry product to set quickly.

Cracks deeper than 1/8-inch should be treated with a different type of repair. This is because they indicate a serious problem with the foundation of the building, which a professional should assess. In addition to repairing the crack, a professional should be able to provide solutions to prevent it from happening again, such as putting in expansion joints or a weep screed.

The best way to treat these cracks is by using a special product that is specifically designed for this type of repair. It is important to choose a product that will adhere well to the crack, and this can be done by choosing a mix that is ready to trowel on or that can be mixed in a wheelbarrow or plastic tray with a specific type of masonry primer. Ideally, the product should be a hydraulic lime or have a pozzolanic additive such as crushed brick dust to ensure a fast set.


Stucco is a beautiful material that adds value to your home and is very durable, but over time normal wear and tear can cause holes in stucco walls. When left unattended, holes can cause serious structural damage and allow water to seep behind the stucco, causing mold and mildew. This is why it is important to perform regular inspections for signs of damaged or broken stucco and have any problems repaired quickly by an experienced team like Orlando Stucco Repair Pros.

Small holes in stucco can be repaired fairly easily by using a premixed acrylic stucco patching compound that is available at most hardware and home improvement stores or mixing up a batch of stucco tinted to closely match the original color of the stucco on your house. Applying a thin coat of the patching compound with a putty knife should fill the hole and blend it into the surrounding stucco. You may need to apply more than one layer to fill the hole completely.

Before you apply the new stucco, make sure that the hole is framed with a piece of grade-D builder’s paper and affixed to the wooden lath underneath with galvanized roofing nails. This will help keep moisture and other unwanted substances from damaging the underlying wood. It’s also important that the new stucco be applied over a fresh, cured layer of sand and cement. Ideally, the cement should be hydraulic or pozzolanic and matched to the existing stucco in particle size, color, and consistency.

Once the patch is cured, you can paint over it to create a seamless look. You should wait a week or so before you paint this layer, though, so that the patch has had enough time to properly set and bond with the rest of your stucco.

While some larger cracks and holes are to be expected in a home, many of them could mean that there is an underlying problem. If you notice a lot of large cracks and holes, it might be time to call a professional to troubleshoot the issue and find out what is causing it.

Water Damage

Water damage in stucco is one of the most serious problems homeowners can face. It can lead to mold and other structural problems, and it’s crucial to seek repair as soon as possible. Stucco has a lot of structural integrity, but even small amounts of water can cause damage over time. The best way to prevent water damage in stucco is to have it installed correctly by a reputable contractor. In addition, a building inspector can help ensure that the stucco is properly sealed where it connects with windows, flashing and other areas where moisture can easily penetrate the walls.

The most common sign of water damage in stucco is stains or discoloration. These are caused by water seeping into the stucco and causing mineral deposits or efflorescence. They’re usually easier to notice than cracks or holes, and they may be accompanied by other signs of water intrusion, such as mold growth or a musty or stale odor.

Another sign of water damage in stucco is crumbling or brittle material. This is often a result of improper installation, but it can also indicate that there’s rotting wood or other underlying issues underneath. It’s important to get these issues fixed right away, as they can be a major safety hazard for your family.

If you’re noticing any of these 7 signs of water damage in your stucco, it’s time to call in the professionals. A stucco specialist can diagnose the problem and recommend the best course of action. They’ll start by checking the area for moisture penetration or other damage to sheathing and insulation, then repair it as needed. They’ll use a base coat and finish coat to match the existing color of your stucco, and they’ll perform a final inspection and cleanup.

Water damage in stucco can be hard to detect, especially if you don’t know what to look for. However, with regular maintenance and routine inspections, you can spot problems early on and avoid expensive repairs.

Besides being unsightly, mold in stucco can also lead to structural damage. It can seep into the walls, causing rot, or enter the living space and aggravate allergies and asthma in people. Stucco can be treated for mold and mildew stains, but the most important step is to find the cause of the problem.

Check the gutters, around windows and doors, as well as behind any bushes, flowers or trees that grow near the house for signs of mold and mildew. In addition, inspect the area where water pools, indicating a potential leak or drip. If the problem persists, a moisture meter reading may be required to determine the source of the problem.

Mold in stucco can be remedied with oxygen bleach, which can be purchased at hardware or home improvement stores. Liberally coat the affected area and allow it to sit for about 30 minutes, or longer for stubborn stains. After rinsing the area, scrub the stain using a soft-bristle brush or power washer with a rotating brush attachment, applying firm pressure. When the stains are gone, rinse the area again with water.

If the cracks in your stucco are not repaired, water may seep into the wall cavities and rot the framing. This is a more serious problem than just a cosmetic issue, and you should consult a stucco professional.

Depending on the extent of the cracks and the amount of water damage, the cost to repair stucco can vary. Generally, smaller cracks and minor rot can be repaired with a premixed stucco patching product. Larger cracks in the stucco or signs of excessive water damage require more extensive repairs, and the use of a special cement.

A professional can diagnose the cause of the damage by conducting an inspection, which includes inserting probes into suspected areas to determine the level of moisture in the wall cavity. Once the problem is determined, holes are caulked and the surface is resealed. Stucco is a tougher building material than EIFS, which means it usually costs more to repair. However, a contractor will be able to provide an accurate estimate once the inspection is complete.
