Why Does Mildew Grow On Your Building's Siding And How To Remove It
Why Does Mildew Grow on Your Building's Siding and How to Remove It: Understanding What It Means
Understanding Mildew and Mold
Mildew and mold are types of fungi that thrive in moist environments. While often used interchangeably, they are distinct entities. Mildew typically appears as a flat, powdery substance, usually white or gray, while mold tends to be fuzzy and black, green, or blue. Both can cause deterioration and discoloration on building surfaces, including house siding. Unlike mildew, which remains on the surface, mold grows deeper into materials, causing more extensive damage. The presence of mold can often be detected by a musty smell around the exterior walls, indicating potential hidden mold in less visible areas of siding.
What is Mildew and How Does it Differ from Mold Growth?
Mildew is a type of fungus that thrives on surfaces, particularly in damp and shaded areas. Often confused with mold, mildew has distinct characteristics that set it apart. Mildew typically appears as a white or gray powdery substance, whereas mold can be green, black, or brown with a slimy texture and reproduces with tiny spores that can’t be seen with the naked eye. Unlike mold, which can penetrate deeper into materials and cause extensive damage, mildew tends to remain on the surface, making it less aggressive. Understanding these differences is crucial for effective treatment and prevention of these fungi on your home’s exterior. Additionally, preventing mold growing on home siding is important to avoid potential damage to the house and associated health risks.
How Mildew Appears on Exterior Surfaces
Mildew manifests on house siding as unsightly patches that can impair the property’s appearance. It often appears in shaded areas where sunlight is minimal and moisture accumulates. Siding made from organic materials like wood is particularly susceptible, though vinyl siding is not immune to these growths. Visible mold and mildew can significantly detract from the aesthetic appeal of your home. The composition of the siding material influences its susceptibility to mold, with certain materials, like Hardie siding, specifically designed to resist such issues.
Mildew thrives in damp conditions, feeding off grime, dust, and organic debris that settles on the siding. This buildup provides a perfect breeding ground, especially if the siding is exposed to frequent rainfall or high humidity levels.
Environmental Factors Leading to Mildew Growth
Several environmental factors contribute to the appearance of mildew on house siding. Humid climates, overgrown vegetation, inadequate drainage, and poor ventilation can exacerbate the problem. The orientation of the building also plays a crucial role; north-facing walls receive less sunlight, remaining cooler and damper, thus promoting mildew growth. While bleach is effective on non-porous surfaces, its efficacy diminishes on porous surfaces like wood siding, emphasizing the need for specialized cleaners.
Recognizing these factors allows property owners and facility managers to take proactive steps in preventing and managing mildew. Understanding the causes can help tailor maintenance strategies that preserve the building’s aesthetic and structural integrity. By addressing these factors, you can prevent mold from growing on your siding and maintain your home’s exterior.
Causes of Mildew Growth on Siding
Mildew growth on siding is often the result of several contributing factors, including excessive moisture, poor ventilation, and inadequate sunlight. Recognizing these causes is essential for preventing mildew growth and maintaining the integrity of your home’s exterior. Additionally, it is important to prevent mold growth on siding by taking proactive measures to minimize moisture exposure, such as maintaining gutters, using dehumidifiers, and regularly inspecting siding.
Excessive Moisture Around the Home Exterior
Excessive moisture is a primary culprit behind mildew growth on siding which encourages mold growth. This can stem from various sources such as poor drainage around the home, clogged rain gutters and downspouts, leaks in the roof or walls, high humidity levels, and insufficient ventilation. To combat this, ensure your home’s drainage system is functioning correctly, and consider using a dehumidifier to reduce indoor moisture levels. Properly managing moisture is a key step in preventing mold and mildew from taking hold of your siding.
Too Much Shade Around the Home
Excessive shade around your home can also contribute to mildew growth on siding. Shaded areas tend to be cooler and more humid, creating an ideal environment for mildew to thrive. To mitigate this, consider trimming trees or shrubs to allow more direct sunlight to reach your home’s exterior. Increased exposure to sunlight can help keep these areas drier and less hospitable to mildew spores. Additionally, different cleaning agents vary in their ability to kill mold on various surfaces; for instance, while bleach can kill mold on non-porous surfaces, it is less effective on porous materials and may cause damage.
Poor Ventilation and Drainage
Poor ventilation and drainage are significant factors that can lead to mildew growth on siding. Ensuring your home’s ventilation system is working properly is crucial. Installing vents or fans can improve airflow, reducing the likelihood of mildew forming from wet or damp spots. Additionally, make sure your home’s drainage system is effective. Installing solutions like French drains can help prevent water accumulation around your home, further reducing the risk of mildew growth.
By understanding and addressing the causes of mildew growth on siding, you can take proactive steps to prevent potentially toxic substances from growing. Regular cleaning and maintenance, improving drainage and ventilation, and using the right cleaning solutions can all help to keep your home’s exterior looking its best and free from mildew. Maintaining the home's exterior is essential to prevent mildew and mold growth, which can thrive in damp conditions.
Can Mold On The Siding Make You Sick?
Mold, especially black mold on the outside of a house, can be a substantial concern for property owners and facility managers. While outdoor mold might not always seem as threatening as indoor mold, it can still pose health risks under certain conditions. Therefore, it is crucial to remove mold from siding to prevent potential health risks.
Health Risks Associated with Mold Exposure
Exposure to mold spores from the mold on the outside of a house can lead to various health issues, especially for those with respiratory conditions, allergies, or weakened immune systems. Symptoms of mold exposure can include nasal congestion, coughing, throat irritation, or more severe respiratory problems. It is essential to understand that while mold on siding is outdoors, wind or other elements can carry its spores indoors, potentially impacting indoor air quality. Therefore, it is crucial to prevent mold growth on home siding to avoid potential health risks.
Understanding Black Mold and Other Types of Mildew
Black mold on vinyl siding is often considered more hazardous due to the potential production of mycotoxins, which can pose serious health threats. However, not all black-colored mold is harmful; identifying the type is crucial for assessing risk accurately. Other types of mildew might not be as dangerous but can still cause aesthetic and structural issues. While bleach is effective on non-porous surfaces, its efficacy diminishes on porous surfaces like wood siding, emphasizing the need for specialized cleaners.
Evaluating the Impact on Indoor Air Quality
Although the mold resides on the exterior surfaces, its spores can penetrate indoor spaces through ventilation systems, open windows, or doors, compromising indoor air quality. Regular assessments and prompt remediation can prevent potential health risks and ensure a healthier indoor environment. Additionally, maintaining the home's exterior is crucial to prevent mildew and mold growth, which can thrive in damp conditions.
How To Remove Mildew From Exterior Siding?
Step-by-step Guide to Cleaning Mildew on Siding
The external appearance of your building plays a crucial role in its overall impression and value. Therefore, it is vital to remove mildew from the siding promptly and effectively. Begin with identifying the affected areas and assessing the extent of the mildew damage. Safety first: wear appropriate protective gear, such as gloves and masks, to avoid exposure to mold spores. Different cleaning agents vary in their ability to kill mold, with bleach being effective on non-porous surfaces but less so on porous materials, and professional techniques like soft washing using biodegradable solvents designed to kill mold and mildew safely.
Next, rinse the siding with a garden hose to remove loose dirt and debris. This cleaning step facilitates a better view of the mildew spots. A scrub brush with soft bristles can be used to gently scrub the siding using a warm water and soap cleaning solution for a more thorough cleanse.
Recommended Cleaning Solutions and Tools
For a more effective method to get rid of mold on the outside of the house, it is beneficial to use a commercially available vinyl siding cleaner or a mixture of vinegar and water. Mix one part white vinegar with three parts water and apply the solution with a spray bottle. Let it sit for at least 20 minutes before scrubbing it with the brush and rinsing it off with water.

While bleach is effective on non-porous surfaces, its efficacy diminishes on porous surfaces like wood siding, emphasizing the need for specialized cleaners.
Using Anti-Mold Spray for Effective Results
Once the initial mold removal is complete, applying an anti-mold spray for vinyl siding helps prolong the cleanliness and prevent recurrence. These sprays are formulated to inhibit mold spores from settling and thriving on surfaces. Follow the manufacturer’s instructions for application and drying times for optimal results.
How To Stop Mildew On Siding?
While cleaning and removing mildew from your building’s siding is essential, preventing growth is even more crucial.
