Stucco is more resilient than other home siding options but still requires proper care to avoid issues like moisture damage. If you notice stains, cracks, or mold, contact a stucco remediation contractor.
Remediation involves replastering the entire wall system to address the underlying issues that cause moisture damage. It’s more involved than a repair, but it offers lasting results. Contact Stucco Remediation Philadelphia now!
Stucco is porous, which means it can allow moisture into the interior walls if there are cracks or other damage. Moisture infiltration leads to mold, mildew, and other unwanted fungi growth that can stain the stucco surface.
Regularly inspecting your stucco exterior for dirt, grime, and other debris will help keep the surface clean and stain-free. If you notice any areas of discoloration, a thorough washing with a pressure washer will typically do the trick. Always be sure to use a sprayer with an extension hose and a nozzle set to “low” pressure. Using too much pressure can damage the stucco and force water into cracks.
Before you start washing, walk around your house’s perimeter to evaluate the stucco’s condition. A close inspection will show you if there are any cracks in the stucco that need to be repaired. This is important because cracks can allow moisture into the wall, which will lead to further problems.
Moisture stains on the stucco surface are common, but there are other signs that could indicate more serious problems. For example, if the paint is peeling, this is usually caused by water penetration and may indicate a moisture problem beneath the surface. Another sign of moisture is a musty odor, which could be an indication that there is mold growing behind the stucco.
In addition to stains, the stucco can also develop a powdery residue called efflorescence due to water exposure. Efflorescence occurs when water-soluble salts migrate to the surface of the stucco and leave a white, powdery residue as they evaporate. This can be especially noticeable in areas where there is a lot of humidity or water exposure.
Using a brush, scrub the affected area with a solution of mild detergent and warm water. If the stains are black, this is probably mildew and should be treated with bleach. If the stains are green, this is likely algae, and can be treated with a combination of bleach and Borax. A combination of this and a regular wash with liquid dish soap will keep the stucco looking great.
Cracks
When hairline cracks appear in the stucco, it’s best to remediate them right away. They may seem insignificant at first, but they’ll eventually become larger and cause even more damage. Moisture that is trapped behind these cracks can lead to black mold and rot. If left untreated, these problems can lead to costly structural repairs or even the loss of your home.
There are a number of causes for the cracking of stucco, including foundation settlement, excessive moisture exposure, and large temperature fluctuations. Foundation settling often occurs in older homes, and it can place stress on the walls. This can cause the stucco to expand and contract, which leads to cracks over time. Excessive moisture exposure can occur from rain or irrigation systems, or it can be caused by poor drainage, which allows water to seep through the wall and into the house. Large temperature fluctuations can also cause the stucco to expand and contract, leading to cracking.
Remediation is usually a more expensive service than repair, so homeowners should only use it when necessary. However, it is important to consider the long-term health of your home and make the best decision for you. Remediation can be used to fix serious issues that are unlikely to be fixed by simple repair, so it’s worth the investment.
The first step in the remediation process is to clean the crack. This is done by using a broom or brush to remove any dirt or debris that has collected. Next, the crack is carefully inspected to assess its size, shape, and depth. During this assessment, it is important to look for signs of moisture or damage in the surrounding area.
It is also important to determine if the crack is the result of improper installation or if it is part of the natural aging of the stucco. If the crack was caused by improper installation, it’s best to have a professional repair the issue as soon as possible to avoid further damage. If the crack is part of the aging process, it may be possible to fill in the crack with a product that’s designed for this purpose.
Interior Leaks
Stucco provides a traditional aesthetic and durability to homes, but without proper maintenance it can suffer from water damage and even structural failure. In addition to causing unsightly stains and cracks, water leaks from stucco can also lead to serious problems with mold and rot. By detecting and correcting stucco water leaks promptly, you can protect your home and save money.
The most common causes of stucco water leaks are due to a poor installation, or neglect of the weatherproofing system and painting maintenance. Since stucco is very porous, a thorough inspection of the exterior to identify problem areas such as cracked or missing stucco is recommended to prevent excessive moisture penetration. Inadequate flashing and paint maintenance can also cause moisture penetration, especially on south exposures where the wall is exposed to heavy wind driven rain.
If water penetrates the stucco and reaches the wood framing, it can create a rotting condition that requires extensive repair. In some cases, the rot may even reach the interior of your home. This can result in a musty odor and can damage drywall and other interior finishes. Identifying the presence of a hidden water leak in stucco can be difficult, but some cues to look for include dark spots around windows and doors or staining on the stucco itself.
Moisture stains and discoloration on the stucco are often a result of inadequate cleaning. Using a soft brush with a mild cleaner can help to remove these stains. Be sure to pre-wet the surface before washing to overcome absorption of dirty wash water back into the dull finish. Avoid using pressure washers on stucco, as this can erode the surface and accelerate deterioration.
The most important thing to remember is to catch leaks early, as water seepage through stucco will inevitably lead to mold, which in turn can damage your home’s structure and cause health issues for the entire family. Regular inspections of the exterior and interior walls can help you identify potential problem areas, such as a musty odor or brown stains on your stucco. By addressing these issues, you can save yourself the cost and hassle of mold remediation and other costly repairs.
Remediation
Stucco is a common choice for homes in hot and dry climates, but it may not be appropriate for every location. If heavy rains or snowstorms occur regularly in your area, the moisture can cause damage to your stucco. The problem stems from the fact that stucco is a very porous material, which means it will absorb the rain and snow that hits it. The moisture will eventually settle behind the surface, creating a pocket of water that can cause damage to wood and other materials in your home.
The best way to protect your stucco from moisture damage is to have it inspected annually for cracks, holes and separations. If you do spot a problem, it’s important to have it repaired in a timely fashion to prevent further problems. It’s also a good idea to wash your stucco periodically with a mild cleaner and a garden hose with a high-pressure jet. Pre-wetting the surface will help to overcome any absorption and keep dirty wash water from being absorbed back into the dull finish. Don’t use a pressure washer, though, as this can erode the finish.
Another problem is that a poorly executed stucco job can result in an uneven or unattractive finish. This can be a major drawback if you want a smooth, polished look on your walls. Additionally, the textured appearance of stucco may clash with certain interior design styles. While minor cracks and stains can be patched, extensive damage can be costly to repair.
Remediation is the process of reducing contamination at a site to levels that are acceptable for people and the environment. This can be done by removing the contaminants, treating them to reduce their effects, or containing them. Remediation is often required on sites where chemical or biological contaminants have been found.
In historic buildings, remediation can include cleaning or repairing the structure to remove deterioration and restore its appearance. It can also be used to repair a leaking roof or restore features such as doors, windows and moldings. It is important to record the extent of any damage before starting work, so that the results of the remediation can be compared with the original state. The initial step in most remediation projects is a scoping study, which uses information that’s already available to provide an overview of the site and issues. This is typically done as a desktop study, but may be supplemented by a field visit and meetings with key stakeholders.
