Atlanta AC: Vinyl Siding Brewing Silent Lung Mold?
By Franklin Everett ShawThe musty smell hit me the moment I walked in. It wasn’t overpowering, but it was definitely there, a subtle undercurrent to the otherwise clean scent of lemon cleaner. My friend, Sarah, had called me in a panic, convinced something was wrong with her Atlanta home. She’d been experiencing persistent coughs and headaches, and her doctor suggested checking for mold. Little did she know, her seemingly innocuous vinyl siding, combined with Atlanta’s notorious humidity and constant AC use, was likely the culprit.
Vinyl siding, while a popular and relatively low-maintenance choice for Atlanta homeowners, can become a breeding ground for mold if not properly cared for. The combination of trapped moisture, warm temperatures, and readily available organic matter (dust, pollen, and other airborne pollutants) creates the perfect storm. Add to that the constant cycling of air conditioning, which creates condensation on exterior walls, and you have a recipe for disaster.
So, what specific types of mold are we talking about in Atlanta? Aspergillus and Penicillium are common culprits, often appearing as green or black spots. Cladosporium, another frequent offender, thrives in both warm and cool conditions. These molds aren’t just unsightly; they can trigger allergic reactions, asthma attacks, and other respiratory problems, especially in vulnerable individuals like children and the elderly.
Identifying mold early is crucial. Look for discoloration on your vinyl siding, particularly in shaded areas or near seams. Check for musty odors, both inside and outside your home. Sarah’s initial clue was the persistent smell, even after cleaning. Don’t ignore these warning signs!
Now, let’s talk remediation. The big question: DIY or professional? For small, localized mold growth (less than 10 square feet), a DIY approach might be sufficient. However, proceed with caution. You’ll need:
- A stiff-bristled brush
- A mold-killing solution (bleach and water, or a commercial mold remover)
- Protective gear (gloves, mask, eye protection)
Scrub the affected areas thoroughly, rinse well, and allow to dry completely. Important: Never mix bleach with ammonia or other cleaning products, as this can create toxic fumes.
However, if the mold covers a larger area, or if you suspect it’s present inside your walls, hire a professional mold remediation company. They have the expertise, equipment, and protective gear to safely and effectively remove the mold and address the underlying moisture problem.
Cost is a major factor, of course. DIY supplies might cost you $50-$100. Professional remediation, on the other hand, can range from $500 to several thousand dollars, depending on the extent of the problem. Sarah ended up needing professional help, and her bill came to around $2,500. It was a painful expense, but worth it for her health and peace of mind.
One common mistake homeowners make is simply cleaning the visible mold without addressing the source of the moisture. This is like putting a band-aid on a broken leg. The mold will inevitably return.
Another pitfall is using the wrong cleaning products. Some products may only bleach the mold, making it appear to disappear, while the roots remain intact. Always use a product specifically designed to kill mold.
Preventative maintenance is key to avoiding mold problems in the first place. Here’s what Atlanta homeowners should do:
- Regularly inspect your vinyl siding for cracks, gaps, or damage. Seal any openings to prevent water intrusion.
- Clean your siding at least once a year. Use a pressure washer with a low-pressure nozzle, or a soft-bristled brush and soapy water.
- Ensure proper ventilation in your attic and crawl space. This helps to reduce moisture buildup.
- Trim back any trees or shrubs that are touching your siding. This allows for better airflow and sunlight exposure.
- Consider installing gutters and downspouts to direct water away from your foundation. This can help to prevent moisture from seeping into your walls.
For Sarah, the solution involved not only mold remediation but also addressing a leaky gutter that was contributing to the moisture problem. She also invested in a dehumidifier for her basement to further reduce humidity levels.
Living in Atlanta means embracing the humidity, but it doesn’t mean accepting mold in your home. By understanding the risks, taking preventative measures, and acting quickly when problems arise, you can protect your health and your investment. Don’t let your vinyl siding become a hidden health hazard.
