**Austin Walls: Is Cheap Drywall Fueling Summer Asthma?**
By Franklin Everett ShawThe air in your Austin home feels heavier than usual, and your allergies are acting up even with the windows closed. You’ve cleaned, you’ve dusted, but something still feels off. Could the very walls be the culprit? In the rush to rebuild after devastating hurricanes, some Texas homes, particularly those built or renovated in the mid-2000s, may have been constructed with imported drywall that emits sulfurous gases. This “problem drywall” can wreak havoc on your health and home.
This article will investigate the potential link between Austin Walls drywall, commonly used in Texas construction (especially post-hurricane rebuilding), and increased summer asthma symptoms, offering practical tips for identifying potentially problematic drywall and suggesting remediation steps specific to Texas homeowners. We’ll guide Texans on how to test their homes for sulfur off-gassing from drywall and explore air purification strategies effective against these specific compounds, referencing Texas-specific resources for air quality testing and remediation.
The problem with “problem drywall” stems from its composition and manufacturing process. Much of the drywall imported during the housing boom, particularly from China, contained high levels of strontium sulfide. This compound, when exposed to heat and humidity (hallmarks of a Texas summer), releases hydrogen sulfide, carbonyl sulfide, and carbon disulfide. These gases are not only odorous (think rotten eggs) but can also corrode copper wiring, blacken silver, and, most importantly, trigger respiratory problems.
How do you know if your Austin home might be affected? The most obvious sign is a persistent, unpleasant odor, especially noticeable in enclosed spaces like closets or bathrooms. Look for blackened copper wiring around electrical outlets and appliances. Check the manufacturing markings on exposed drywall in unfinished areas like the attic or garage. If you see markings indicating it was manufactured in China between 2004 and 2008, you have reason to be concerned.
But visual cues aren’t always enough. A more definitive step is to test for sulfur off-gassing. Several methods exist, ranging from DIY kits to professional air quality testing. DIY kits, available at many hardware stores in the Austin area, typically involve placing a copper coupon in a sealed container with a sample of your drywall. After a set period, you compare the coupon to a color chart to estimate the level of corrosion.
However, these kits offer only a rough estimate. For a more accurate assessment, consider hiring a certified indoor air quality professional. They can conduct more sophisticated tests, measuring the specific levels of hydrogen sulfide and other sulfur compounds in your home. In Texas, you can find qualified professionals through organizations like the Texas Department of Licensing and Regulations (TDLR), which licenses mold assessors and remediators. While mold isn’t the same as drywall off-gassing, these professionals often have the expertise and equipment to test for a range of indoor air pollutants.
Let’s say you’ve confirmed the presence of problematic drywall. What now? Remediation can be a complex and costly process, but it’s essential for protecting your health and property. The most effective solution is complete drywall removal and replacement. This is a major undertaking, involving not only the cost of new drywall and installation but also the expense of disposing of the contaminated material.
Before embarking on a full-scale removal, consider less invasive options, especially if the off-gassing is relatively mild. Air purification can help reduce the concentration of sulfurous gases in your home. Look for air purifiers with activated carbon filters, which are particularly effective at absorbing these compounds. Ensure the purifier has a high CADR (Clean Air Delivery Rate) appropriate for the size of the room.
Another strategy is to improve ventilation. Open windows and doors whenever possible to allow fresh air to circulate. Install or upgrade exhaust fans in bathrooms and kitchens to remove moisture and odors. In Austin’s humid climate, a dehumidifier can also help reduce off-gassing by lowering the moisture content in the air.
However, these measures are only temporary solutions. If the drywall is significantly off-gassing, removal is the only way to eliminate the problem completely. When replacing the drywall, ensure you use high-quality, US-made products that meet current building codes. Ask your contractor for documentation verifying the drywall’s origin and composition.
One common mistake homeowners make is attempting to seal the drywall with paint or other coatings. This may temporarily mask the odor, but it won’t stop the off-gassing. In fact, it can trap the gases, potentially leading to higher concentrations and more severe corrosion.
Another pitfall is neglecting to address the underlying cause of the problem. High humidity levels exacerbate off-gassing, so it’s crucial to control moisture in your home. Repair any leaks, ensure proper ventilation, and consider using a dehumidifier, especially during the humid summer months.
Navigating the complexities of “problem drywall” can be daunting, but resources are available to help Texas homeowners. The Texas Department of State Health Services (DSHS) offers information on indoor air quality and potential health hazards. The Better Business Bureau (BBB) can help you find reputable contractors for testing and remediation.
Consider the case of a family in Round Rock, Texas, who experienced persistent respiratory problems and a strange odor in their home. After suspecting “problem drywall,” they hired a certified indoor air quality professional who confirmed the presence of high levels of hydrogen sulfide. The family ultimately had to remove and replace all the drywall in their home, a costly but necessary step to protect their health.
Don’t underestimate the potential impact of “problem drywall” on your health and home. If you suspect your Austin home may be affected, take action. Test your air, consult with professionals, and implement appropriate remediation strategies. Your health and the value of your home depend on it. Remember, a healthy home starts with healthy walls.
