**Austin Air: Is "Green" Siding Hiding Deadly Mold?**
By Franklin Everett ShawThe tell-tale signs are subtle at first: a faint, earthy odor near the baseboards, perhaps a slight discoloration on the green siding that you initially dismiss as dirt. But then, the nagging feeling creeps in – could it be mold? In Austin, Texas, with its humid subtropical climate, the conditions are ripe for mold growth, especially behind siding, and the popular choice of green siding can sometimes mask the early warning signs. Ignoring this potential problem can lead to significant structural damage and health issues.
This article will explore the potential for mold growth behind Austin, Texas homes with green siding, focusing on factors like humidity and specific siding materials common in the area. We’ll provide a step-by-step guide on identifying mold, testing suspect areas, and safe removal or remediation methods, including specific local Austin resources.
The Austin climate is a breeding ground for mold. The combination of high humidity, especially during the spring and fall, and warm temperatures creates an ideal environment for mold spores to thrive. Add to this the fact that many Austin homes are built with wood framing, which provides a food source for mold, and you have a recipe for potential problems.
Green siding, while aesthetically pleasing and often chosen to blend with the natural surroundings, presents a unique challenge. Darker shades of green can absorb more heat, potentially creating temperature gradients behind the siding that encourage condensation. This condensation, trapped between the siding and the wall, provides the moisture mold needs to flourish. Furthermore, the green color can sometimes camouflage early stages of mold growth, making it harder to detect until the problem becomes more severe.
Common siding materials in Austin include:
Wood Siding: While offering a classic look, wood is highly susceptible to mold, especially if not properly sealed and maintained. Cedar and redwood are more resistant than pine, but all wood siding requires regular inspection and treatment.
Vinyl Siding: A more affordable and lower-maintenance option, vinyl is generally mold-resistant. However, improper installation or damage can create gaps where moisture can accumulate, leading to mold growth on the sheathing behind the vinyl.
Fiber Cement Siding (e.g., Hardie Board): This durable material is resistant to rot and insects, but it’s not entirely immune to mold. If the paint or sealant is compromised, moisture can penetrate the fiber cement and support mold growth.
Metal Siding: Aluminum and steel siding are generally mold-resistant, but condensation can still form behind the siding, especially in areas with poor ventilation.
Identifying mold early is crucial. Look for these telltale signs:
Musty Odor: A persistent musty or earthy smell, especially after rain, is a strong indicator of mold.
Visible Stains: Discoloration on the siding, even if subtle, should be investigated. Look for dark spots, streaks, or a fuzzy growth. Remember that on green siding, mold may appear as a slightly darker or lighter shade of green, or even black.
Water Stains: Water stains on interior walls or ceilings near exterior walls can indicate a leak behind the siding, which can lead to mold growth.
Allergic Reactions: Unexplained allergy symptoms, such as sneezing, coughing, or itchy eyes, can be a sign of mold exposure.
Step-by-Step Guide to Identifying and Testing for Mold:
Visual Inspection: Carefully examine the siding, paying close attention to areas around windows, doors, and vents. Use a flashlight to inspect hard-to-reach areas.
Sniff Test: Trust your nose. A musty odor is a strong indicator of mold.
Moisture Meter: Use a moisture meter to check the moisture content of the siding and the wall behind it. Elevated moisture levels (above 16%) indicate a potential problem. You can rent these from most hardware stores in Austin, like Home Depot or Lowe’s.
Surface Testing: If you suspect mold, you can use a mold test kit to collect a sample. These kits are available at most hardware stores and online retailers. Follow the instructions carefully. There are two main types of tests:
Swab Test: This involves swabbing a visible mold growth and sending the sample to a lab for analysis. This will identify the type of mold present.
Air Test: This involves collecting an air sample to determine the concentration of mold spores in the air. This is useful for detecting hidden mold.
Professional Inspection: If you’re unsure about the results of your testing or if you suspect a large mold problem, it’s best to call a professional mold inspector. They have the expertise and equipment to accurately assess the situation and recommend the appropriate course of action. In Austin, consider contacting companies like Mold Inspection Sciences Texas or Austin Mold Inspection.
Safe Mold Removal and Remediation:
Small Areas (Less than 10 Square Feet): You can often handle small mold problems yourself. Wear protective gear, including gloves, a mask (N-95 or higher), and eye protection. Clean the affected area with a solution of bleach and water (1 part bleach to 10 parts water). Be sure to ventilate the area well.
Large Areas (More than 10 Square Feet): For larger mold problems, it’s best to hire a professional mold remediation company. They have the training and equipment to safely remove the mold and prevent it from spreading. In Austin, companies like Dry Force and Blackmon Mooring offer mold remediation services.
Common Mistakes and Pitfalls:
Ignoring the Problem: Mold problems don’t go away on their own. The longer you wait, the worse the problem will become.
Improper Cleaning: Simply wiping away the visible mold is not enough. You need to kill the mold spores and address the underlying moisture problem.
Using the Wrong Cleaning Products: Some cleaning products can actually make mold problems worse. Avoid using ammonia or vinegar, as these can feed mold.
Not Addressing the Moisture Source: If you don’t fix the underlying moisture problem, the mold will simply return.
DIY Remediation for Large Areas: Attempting to remediate a large mold problem yourself can be dangerous and ineffective. You could inadvertently spread the mold spores to other areas of your home.
Local Austin Resources:
City of Austin Code Compliance: The City of Austin has codes and regulations regarding mold growth in rental properties. Contact them if you have concerns about mold in your rental unit.
Texas Department of State Health Services: The Texas DSHS provides information and resources on mold and indoor air quality.
Local Mold Remediation Companies: As mentioned earlier, companies like Dry Force, Blackmon Mooring, Mold Inspection Sciences Texas, and Austin Mold Inspection offer mold inspection and remediation services in Austin.
Preventing Mold Growth:
Control Humidity: Use dehumidifiers, especially in bathrooms and basements. Aim for a humidity level of 30-50%.
Ventilate Properly: Ensure adequate ventilation in bathrooms, kitchens, and laundry rooms. Use exhaust fans when showering or cooking.
Fix Leaks Promptly: Repair any leaks in your roof, plumbing, or siding immediately.
Clean Gutters Regularly: Clogged gutters can cause water to back up and seep into your home.
Maintain Siding: Regularly inspect your siding for damage and repair any cracks or holes. Re-seal or re-paint as needed.
Consider Mold-Resistant Materials: When building or remodeling, consider using mold-resistant materials, such as mold-resistant drywall and treated lumber.
Don’t let mold take hold behind your green siding. By being proactive, vigilant, and informed, you can protect your home and your health from the dangers of mold. Remember, early detection and prompt action are key to preventing serious problems. And when in doubt, consult with a qualified professional.
