**"Atlanta Bricks: Humidity Hiding Deadly Mold?"**
By Franklin Everett ShawThe subtle discoloration on your Atlanta brick home might be more than just dirt. That faint musty smell wafting from the exterior walls? It could be mold, and in Atlanta’s humid climate, it’s a common, persistent problem. Ignoring it won’t make it disappear; in fact, it will only worsen, potentially impacting your health and devaluing your property. This guide provides Atlanta homeowners with a practical, step-by-step approach to identifying, testing, and safely removing mold from brick exteriors, tailored to our unique climate and the types of brick prevalent in neighborhoods like Buckhead and Midtown.
First, let’s talk about identification. Mold on brick often appears as dark green, brown, or black staining. Sometimes it can even be white or grey. Look for discoloration concentrated in areas that stay damp, like near the ground, under eaves, or around downspouts. A musty odor is another key indicator, even if you can’t see visible mold.
DIY testing is a good starting point. You can purchase a mold test kit from most hardware stores, including those on Cobb Parkway. These kits typically involve taking a surface sample with a swab and sending it to a lab for analysis. Alternatively, the “tape test” is a simple, albeit less precise, method. Press clear tape firmly onto the suspected mold, then stick it to a clean, dark-colored piece of paper. Examine the tape closely with a magnifying glass; if you see mold spores, it’s a strong indication of a problem. Remember, these DIY tests are screening tools; a professional mold inspection is recommended for definitive results, especially if you suspect widespread contamination.
Now, for the crucial part: safe removal. Before you even think about cleaning, prioritize your safety. Wear appropriate personal protective equipment (PPE), including a respirator mask rated N-95 or higher (available at most hardware stores), gloves, and eye protection. This is non-negotiable; mold spores can cause respiratory problems and allergic reactions.
Next, choose your cleaning solution carefully. Avoid bleach; while it might seem like a quick fix, bleach is often ineffective on porous surfaces like brick. It primarily removes the color of the mold, not the root system, and can even damage the brick over time. Instead, opt for an EPA-approved mold cleaner specifically designed for exterior use. These cleaners are formulated to penetrate the brick and kill the mold at its source. A good option is a solution containing quaternary ammonium compounds, readily available at home improvement stores in the metro area.
Application is key. Follow the manufacturer’s instructions carefully. Typically, you’ll apply the cleaner with a garden sprayer or brush, ensuring thorough coverage of the affected area. Allow the cleaner to dwell for the recommended time (usually 10-15 minutes) before scrubbing gently with a stiff-bristled brush. Avoid using a pressure washer, as it can damage the brick and spread mold spores.
Rinsing is just as important as cleaning. Use a garden hose to thoroughly rinse the treated area, removing all traces of the cleaning solution and dislodged mold. Be mindful of runoff; avoid directing it towards gardens or other sensitive areas.
Ventilation is critical, especially in Atlanta’s humid climate. After cleaning, ensure the area dries completely. Open windows and doors to promote airflow. Consider using a dehumidifier to speed up the drying process, particularly in shaded areas.
Preventing recurrence is the ultimate goal. Address the underlying cause of the moisture problem. Are your gutters clogged? Are your downspouts directing water towards the foundation? Are there any leaks in your roof or siding? Repairing these issues is essential to prevent mold from returning.
Consider applying a mold-resistant sealant to the brick after cleaning. This will help to create a barrier against moisture and prevent mold growth. Look for sealants specifically designed for brick exteriors, available at most paint stores.
Pay attention to landscaping. Trim back bushes and trees that are close to the house, as they can trap moisture and create a favorable environment for mold growth. Ensure proper drainage around the foundation.
One common mistake Atlanta homeowners make is underestimating the severity of the problem. They might try to clean a small area of mold with a household cleaner, only to find that it returns within a few weeks. This is because they haven’t addressed the underlying moisture problem or used an effective cleaning solution.
Another pitfall is improper safety precautions. Cleaning mold without proper PPE can expose you to harmful spores, leading to respiratory problems and allergic reactions. Always wear a respirator mask, gloves, and eye protection.
Finally, many homeowners fail to address the root cause of the moisture problem. They might clean the mold, but if they don’t fix the leaky gutter or improve drainage, the mold will inevitably return.
Let’s consider a specific example: a brick home in Midtown Atlanta. This neighborhood, known for its historic architecture, often features older brick homes that are particularly susceptible to mold growth due to their age and porous nature. Imagine a homeowner noticing dark staining on the north-facing side of their house, which receives little sunlight and stays damp for extended periods. They perform a DIY tape test and confirm the presence of mold spores. Following the steps outlined above, they carefully clean the affected area with an EPA-approved mold cleaner, address a leaky gutter that was contributing to the moisture problem, and apply a mold-resistant sealant. By taking these proactive steps, they can effectively remove the mold and prevent its recurrence, protecting their home and their health.
Remember, dealing with mold can be challenging, but with the right knowledge and tools, you can successfully remediate the problem and protect your Atlanta home. If you’re unsure about any aspect of the process, don’t hesitate to consult with a professional mold remediation company. They can provide expert advice and ensure that the job is done safely and effectively.
