Las Vegas Homes: Mold, Drywall, and Desert Lung?
By Franklin Everett ShawThe relentless Las Vegas sun beats down, baking everything in its path. But it’s not just the heat you need to worry about in Sin City; it’s what that heat, combined with occasional monsoon rains and disturbed desert soil, can do to your home’s drywall and your lungs. We’re talking mold, and a particularly nasty fungal infection called “Desert Lung,” or coccidioidomycosis.
This isn’t just about aesthetics; it’s about your health. Let’s dive into how to protect your Las Vegas home and yourself.
First, understand the enemy: mold thrives in damp, dark places. In Vegas, that often means behind drywall, especially after a leaky pipe, a poorly sealed window during a dust storm, or even just condensation from your AC unit.
Drywall acts like a sponge, soaking up moisture and providing the perfect breeding ground.
Desert Lung, on the other hand, is caused by inhaling Coccidioides spores, which live in the soil. Construction, gardening, or even strong winds can stir them up.
Now, let’s get practical. Prevention is always better (and cheaper) than cure.
Start with regular inspections. Check around windows and doors for leaks, especially after heavy rain.
Look for water stains on your ceilings and walls. Feel for dampness, particularly in bathrooms and kitchens.
Don’t ignore musty odors; they’re a telltale sign of mold.
Next, focus on ventilation. Run your bathroom fan during and after showers.
Open windows when the humidity is low to circulate fresh air. Consider a dehumidifier, especially during monsoon season.
Keep your AC unit clean and well-maintained. A dirty AC can contribute to moisture buildup.
Now, let’s talk about DIY remediation. Small mold patches (less than 10 square feet) can often be handled yourself.
You’ll need:
- Protective gear: gloves, mask (N95 or better), and eye protection.
- A mold-killing cleaner: bleach solution (1 part bleach to 10 parts water) or a commercial mold remover.
- Scrub brush and sponges.
- Dry cloths.
Spray the affected area with the cleaner. Scrub thoroughly to remove the mold.
Wipe down the area with a clean, damp sponge. Dry the area completely with a clean cloth.
Dispose of the sponges and cloths properly.
Important: Never mix bleach with ammonia or other cleaning products. This can create toxic fumes.
However, there are times when DIY isn’t enough. If the mold covers a large area (more than 10 square feet), or if you suspect it’s behind walls or in your HVAC system, call a professional.
Also, if you or anyone in your family has respiratory problems, err on the side of caution and hire a professional.
Choosing the right professional is crucial. Look for companies that are licensed, insured, and certified in mold remediation.
Ask for references and check online reviews. Get multiple quotes before making a decision.
A good remediation company will:
- Identify the source of the moisture problem.
- Contain the affected area to prevent the spread of mold spores.
- Remove the mold-infested materials.
- Clean and disinfect the area.
- Repair the moisture problem.
- Conduct post-remediation testing to ensure the mold is gone.
Now, let’s address the Desert Lung risk. Minimize dust exposure by wearing a mask when gardening or doing yard work.
Water down soil before digging to reduce dust. Avoid disturbing soil during windy days.
Consider using HEPA air filters in your home to capture airborne spores.
If you develop flu-like symptoms, such as fever, cough, and fatigue, that don’t improve after a few weeks, see a doctor and mention your potential exposure to Coccidioides. Early diagnosis and treatment are crucial.
Las Vegas has specific challenges. The alkaline soil is particularly conducive to Coccidioides growth.
The rapid temperature changes can cause condensation inside walls. The intense sun can degrade building materials, creating cracks and leaks.
Common mistakes homeowners make include:
- Ignoring small leaks.
- Not ventilating properly.
- Using the wrong cleaning products.
- Trying to cover up mold instead of removing it.
- Delaying professional help when needed.
To find local testing and remediation services, check with the Nevada State Contractors Board for licensed contractors. The Southern Nevada Health District can provide information on mold and indoor air quality.
For Desert Lung information, consult your doctor or the Centers for Disease Control and Prevention (CDC).
Maintaining healthy indoor air quality in Las Vegas requires vigilance. Regular inspections, proper ventilation, prompt remediation, and awareness of Desert Lung risks are essential.
Don’t underestimate the power of prevention. A little effort can go a long way in protecting your home and your health in the challenging Las Vegas environment. Remember, your health is worth more than a gamble.
