**Reno's Mold: Cheap Siding Crashing Summer Lungs?**
By Franklin Everett ShawThe air in Reno during the summer months can be deceptively harsh. While the days are dry and sunny, the occasional humidity spikes can create a breeding ground for mold, especially in older homes with less-than-ideal siding. This isn’t just an aesthetic issue; it’s a potential health hazard, particularly for those with respiratory sensitivities.
Let’s dive into the connection between specific siding types, mold growth, and respiratory problems in Reno, Nevada.
Certain affordable siding options, popular in Reno’s older neighborhoods, are more susceptible to moisture retention. This creates the perfect environment for mold to flourish, especially during those brief periods of high humidity.
One culprit is T1-11 siding, a plywood product often used in the 70s and 80s. Its porous nature and vertical grooves can trap moisture, leading to rot and mold growth, particularly if not properly sealed and maintained.
Another common siding type in Reno is vinyl siding. While generally durable, improper installation or damage can create gaps where moisture can penetrate, leading to mold growth behind the siding.
The problem isn’t just the presence of mold; it’s the type of mold. Stachybotrys chartarum, often called “black mold,” thrives in damp environments and produces mycotoxins that can trigger respiratory issues like asthma, allergies, and even more severe health problems.
Identifying problematic siding is the first step. Look for these telltale signs:
- Visible mold or mildew growth: This can appear as black, green, or white patches on the siding surface, especially in shaded areas or near the ground.
- Warping or buckling: This indicates that the siding has absorbed moisture and is starting to deteriorate.
- Soft spots: Probe the siding with a screwdriver. If it feels soft or spongy, it’s likely rotting from the inside out.
- Musty odors: A persistent musty smell, especially after rain, can indicate hidden mold growth behind the siding.
If you suspect mold, don’t attempt to remove it yourself without proper protection. Disturbing mold can release spores into the air, exacerbating respiratory problems.
Instead, contact a certified mold inspector in Washoe County. They can conduct air and surface samples to determine the type and extent of the mold growth.
For remediation, it’s crucial to hire a licensed mold remediation contractor. They will use specialized equipment and techniques to safely remove the mold and prevent its recurrence.
Here’s a step-by-step guide to mold remediation:
- Containment: The affected area is sealed off to prevent the spread of mold spores.
- Removal: Moldy materials, such as siding, drywall, or insulation, are carefully removed and disposed of.
- Cleaning: The remaining surfaces are cleaned with antimicrobial solutions to kill any remaining mold spores.
- Drying: The area is thoroughly dried to prevent future mold growth.
- Repair: Damaged siding or other materials are replaced with mold-resistant alternatives.
Choosing safer siding alternatives is crucial for Reno homeowners. Consider these options:
- Fiber cement siding (e.g., Hardie Board): This durable material is resistant to moisture, rot, and pests.
- Engineered wood siding (e.g., LP SmartSide): This treated wood product is designed to resist moisture and decay.
- Metal siding: Aluminum or steel siding is highly durable and resistant to mold and pests.
When installing new siding, ensure proper ventilation and drainage to prevent moisture buildup. This includes:
- Installing a rain screen: This creates an air gap between the siding and the wall, allowing moisture to escape.
- Using flashing around windows and doors: This prevents water from penetrating the wall cavity.
- Ensuring proper grading around the foundation: This directs water away from the house.
Reno and Washoe County have specific regulations regarding mold inspection and remediation. The Washoe County Health District doesn’t directly regulate mold remediation, but they do offer resources and information on indoor air quality.
It’s essential to check with the Nevada State Contractors Board to ensure that any mold remediation contractor you hire is properly licensed and insured.
A common mistake homeowners make is simply painting over mold. This only masks the problem and doesn’t address the underlying moisture issue. The mold will eventually grow back, often worse than before.
Another pitfall is using bleach to kill mold. While bleach can kill surface mold, it doesn’t penetrate porous materials and can actually worsen the problem by providing moisture for the mold to feed on.
Instead of bleach, use a specialized mold cleaner or a solution of vinegar and water. Always wear protective gear, including gloves, a mask, and eye protection, when cleaning mold.
Preventing mold growth is always better than dealing with remediation. Here are some tips for Reno homeowners:
- Regularly inspect your siding for signs of damage or mold growth.
- Keep gutters clean and free of debris to ensure proper drainage.
- Trim trees and shrubs away from the house to improve ventilation.
- Use a dehumidifier in damp areas, such as basements or crawl spaces.
- Address any leaks or water damage promptly.
Don’t underestimate the potential health risks associated with mold growth in your Reno home. By understanding the connection between siding types, moisture, and respiratory issues, you can take proactive steps to protect your health and your home.
Remember to consult with qualified professionals for mold inspection and remediation, and choose safer siding alternatives to create a healthier living environment in the high desert.
