Asheville Asthma: Is New Siding Fueling Lung Yeast?
By Franklin Everett ShawThe air in Asheville, North Carolina, is known for its crispness, its mountain freshness. But what if the very walls of your home were subtly undermining that purity? Could the siding you chose to protect your house be contributing to respiratory issues, specifically lung yeast infections like Aspergillosis? It’s a question worth asking, especially given the unique climate and construction trends in this vibrant mountain town.
Aspergillosis, an infection caused by Aspergillus mold, thrives in damp environments. Asheville’s humid summers and relatively mild winters create ideal conditions for mold growth. While mold can grow on any surface, certain siding materials, particularly when improperly installed or maintained, can exacerbate the problem.
Let’s delve into the potential link between siding materials and Aspergillosis in Asheville, focusing on popular siding types, their chemical compositions, and practical steps homeowners can take to protect their health.
One prevalent siding choice in Asheville is vinyl siding. It’s affordable and relatively low-maintenance. However, vinyl isn’t breathable. If moisture gets behind the siding – due to leaks, condensation, or improper installation – it can become trapped, creating a breeding ground for mold. Furthermore, some older vinyl siding contains plasticizers like phthalates, which can off-gas and potentially contribute to indoor air quality issues, although the direct link to Aspergillosis is less clear than the mold issue.
Another common option is fiber cement siding, like James Hardie. Fiber cement is more durable and fire-resistant than vinyl. It’s also more breathable, which can help reduce moisture buildup. However, fiber cement is porous and requires proper sealing and painting to prevent water absorption. If the sealant fails or the paint is compromised, moisture can penetrate the siding, leading to mold growth. The manufacturing process of fiber cement also involves chemicals that, while generally considered stable once cured, could potentially release trace amounts of volatile organic compounds (VOCs) under certain conditions.
Wood siding, while aesthetically pleasing and popular in Asheville’s historic neighborhoods, presents its own set of challenges. Wood is naturally susceptible to moisture damage and rot, making it a prime target for mold growth. Regular maintenance, including painting or staining, is crucial to protect wood siding from the elements. Furthermore, some wood siding is treated with preservatives that may contain chemicals that could off-gas.
Engineered wood siding, such as LP SmartSide, offers a compromise between the look of wood and the durability of other materials. It’s treated to resist moisture and insects. However, like fiber cement, it requires proper sealing and painting. Damage to the protective coating can expose the underlying wood fibers to moisture, leading to mold growth. The adhesives used in engineered wood can also be a source of VOCs.
So, how can Asheville homeowners determine if their siding is contributing to a potential Aspergillosis risk?
First, inspect your siding regularly. Look for signs of water damage, such as discoloration, staining, or warping. Pay close attention to areas around windows, doors, and rooflines, where leaks are more likely to occur. Check for visible mold growth, which may appear as black, green, or white patches.
Second, consider a professional mold inspection. A qualified mold inspector can assess the extent of any mold growth and identify the source of the moisture problem. They can also take air samples to determine the concentration of mold spores in your home.
Third, test your indoor air quality. There are DIY air quality test kits available, but a professional assessment is generally more accurate and comprehensive. These tests can identify the presence of mold spores, VOCs, and other pollutants that may be affecting your respiratory health.
Fourth, if you suspect a problem, take action. If you find evidence of mold growth, it’s important to remediate the problem promptly. Small areas of mold can often be cleaned with a bleach solution (one part bleach to ten parts water), but larger infestations may require professional remediation. Address any underlying moisture problems to prevent future mold growth. This might involve repairing leaks, improving ventilation, or installing a dehumidifier.
Fifth, consider the age of your siding. Older siding is more likely to have deteriorated and may be more susceptible to moisture damage and mold growth. If your siding is nearing the end of its lifespan, consider replacing it with a more durable and mold-resistant material.
Sixth, research the specific siding brand and model used on your home. Manufacturers often provide information about the chemical composition of their products and any potential health risks. Look for certifications like GREENGUARD, which indicate that a product has been tested for low chemical emissions.
Seventh, pay attention to your health. If you experience symptoms of Aspergillosis, such as coughing, wheezing, shortness of breath, or fatigue, consult a doctor. Early diagnosis and treatment are crucial to prevent serious complications.
Let’s consider a hypothetical scenario: A homeowner in the historic Montford neighborhood of Asheville notices a musty odor in their basement. They inspect their wood siding and find evidence of rot and mold growth near the foundation. They hire a mold inspector who confirms the presence of Aspergillus mold. The inspector recommends removing the affected siding, remediating the mold, and addressing the underlying moisture problem, which turns out to be poor drainage around the foundation. The homeowner follows the inspector’s recommendations and experiences a significant improvement in their indoor air quality and respiratory health.
Another example: A family in South Asheville recently built a new home with vinyl siding. After a few months, they notice a persistent chemical odor. They suspect that the siding is off-gassing VOCs. They purchase an air quality test kit and find elevated levels of formaldehyde. They contact the builder, who agrees to replace the siding with a low-VOC alternative.
These scenarios highlight the importance of being proactive about identifying and addressing potential siding-related health risks. While there’s no definitive proof of a direct causal link between specific siding materials in Asheville and increased Aspergillosis incidence, the potential for moisture buildup and mold growth associated with certain siding types warrants careful consideration.
Asheville homeowners should prioritize regular inspections, proper maintenance, and informed material choices to protect their respiratory health and enjoy the clean mountain air they deserve. Don’t let your home become a breeding ground for mold. Take control of your indoor environment and breathe easy.
