How Does Stucco Repair Work?

Stucco Repair is a job that involves the complete reapplication of exterior stucco walls. The professionals at Stucco Repair Philadelphia start by covering the repair area with plastic, allowing it to cure and seal without exposure to bad weather conditions.

They may then cut a piece of metal the size of the damaged area with tin snips and staple it to the studs or sheathing. A premixed stucco patch mix is then applied to the hole.

While stucco naturally retains moisture, it can leak and rot if the water is allowed to penetrate the walls. The most obvious sign is visible water spots that can appear as white hazy streaks or dark blotches in the color of your stucco. This isn’t just unsightly; it’s a sign of serious trouble that can lead to mold and other issues that will require further work and expense to resolve.

Moisture in a stucco repair situation can also cause cracks that run deeper than the surface of your home. These can be caused by a number of factors, including shifts in soil, the wrong mixing proportions, and poor workmanship. The best way to address these cracks is through a full remediation service.

This service involves an inspection and the replacement of sheathing, framing, and insulation that have been impacted by water intrusion. It is a more costly service than simple repairs, but it is the only solution that will stop the rot from spreading and save your home.

When it comes to preventing future water damage, the best preventative measure is proper installation of metal flashing at all window and door openings, and especially the bottom of the wall where it meets the foundation. Properly installed flashing will create a water-tight seal, and the use of step and kick-out flashing will ensure that any moisture that does get into your wall will be able to escape.

Stucco can also be protected by a properly installed and maintained caulking system. A high acrylic content caulk can fill cracks that are no wider than a dime, and should be used around windows and doors, as well as at the base of your stucco where it meets the building envelope.


Stucco is a resilient material, but it’s not infallible. Even small chips and cracks can cause problems if they’re not repaired quickly. These problems can lead to moisture intrusion, causing mold, wood rot, or other serious structural issues. In addition, moisture penetration can cause stains. Stucco staining can result from a variety of factors, including dirt, mold, rust, or a lack of proper preparation and cleaning before painting. Fortunately, most stucco staining is a simple fix. Simply clean the surface and apply a fresh coat of exterior paint.

Staining can also be caused by a lack of proper water drainage systems or improper use of rainwater disposal systems. Insufficient drainage can allow excess water penetration, which leads to salt efflorescence, staining, or crumbling surfaces. Water penetration can also cause loss of adhesion between the stucco coats or with the substrate, which may result in bulging and collapse.

In addition, if the original stucco was installed over an old plaster surface, this can accelerate deterioration. This can occur if the plaster is not thoroughly cleaned, sanded, and primed before it’s coated with new stucco. It’s important to choose a primer that’s compatible with concrete and cement-based materials.

Many stains on stucco can be remedied by removing the affected areas of the surface, prepping the remaining areas and adding a fresh coat of exterior paint. However, if the underlying issue is severe — such as moisture intrusion or mold — it may be time for remediation.

The best way to determine whether you need repair or remediation is to have a professional evaluate the structure. The best way to assess whether a homeowner needs repair or remediation is to examine the existing condition of the structure’s stucco, and determine the underlying causes of the damage. Repairing or rehabilitating a damaged stucco surface can prevent further damage and protect the rest of your home from moisture intrusion. In most cases, repair is a more cost-effective solution than remediation. If you suspect you need repair or remediation, contact a professional contractor for further evaluation and estimate.


Stucco is a great material to use for exterior wall coatings and adds value to homes and other buildings. However, like all materials, it can wear down and deteriorate over time. When this happens, the stucco becomes vulnerable to moisture and other factors that can lead to damage.

One of the most common causes of stucco damage is woodpeckers. These birds are known for using their beaks like jackhammers to drill holes in trees and other objects. They often do this in search of food, to communicate with other woodpeckers (through their drumming), or to build nests.

While a woodpecker’s pecking may seem harmless, the constant hammering can cause significant damage over time. It can create cracks, which allow water to seep behind the surface and wreak havoc in the long run.

This can also damage the structure of a building and weaken it, leading to structural issues. If you’re experiencing this issue, a stucco contractor can help.

To prevent woodpeckers from attacking your home, try hanging a suet feeder. These birds go wild over this type of bird feed and will leave you alone if they don’t have a source of shelter to seek out. If this doesn’t work, consider a special woodpecker deterrent paint such as Beakguard. This paint has an odor and taste that repels these birds and stops them from seeking out shelter in your home.

Other methods include installing a woodpecker birdhouse that’s specifically made for the species you have in your area. Or, try hanging fake owls and hawks around your property to scare them away. If you’ve already had damage caused by woodpeckers, it’s important to get these holes repaired as soon as possible.

A qualified contractor can make sure any repairs are done correctly, so that your stucco can last as long as possible. This is especially important if you live in a rainy climate, where moisture can saturate the walls and cause them to deteriorate over time. A stucco repair specialist can help you prevent future problems and keep your Phoenix home looking its best.


Stucco is durable, but it can be vulnerable to cracks and chips that detract from the beauty of your home. In addition to looking unsightly, these problems allow moisture to penetrate the structure and cause damage. It’s important to examine the stucco for these issues and address them immediately to avoid costly repairs in the future.

The best paint for stucco is acrylic latex, which is breathable and will not trap moisture inside the wall. It’s also very easy to apply and clean up, making it a good choice for exterior painting projects. It’s also a good idea to use caulking around windows and doors to prevent moisture from getting into these areas of the house.

During the prep phase for painting stucco, it’s essential to remove all loose dust and dirt. This can be done with a stiff bristle push broom, or in some cases, a power washer may be needed. Once the surface has been cleaned, a masonry-compatible primer should be used. This will help to seal any hairline cracks in the stucco. It’s also a good idea for the primer to be brushed on and left to dry completely before applying a second coat.

Another important factor in the preparation for paint is removing any mildew, mold, or efflorescence. This can be done with a scrub brush or power washer, and it’s also recommended that the surface be sanded down with 80- to 100-grit sandpaper. This will make it easier for the acrylic latex to bond with the stucco surface and hold up over time.

It’s also a good idea to consult a local paint store or home improvement center for recommendations on what kind of paint to use for your project. The store’s staff will be able to give you recommendations on what type of paint is best suited for your climate, as well as the condition of your stucco. They will also be able to offer advice on how to properly prepare the surface for painting, including any necessary repairs that should be made.

It’s important to remember that, even with the proper care and maintenance, your stucco will require some attention over time. It’s a good idea to check it regularly for any signs of wear and tear, such as cracking, chipping, or flaking. By addressing these issues as soon as they occur, you’ll help to ensure that your stucco lasts for decades to come.
