Las Vegas Homes: Sick Building Syndrome's Desert Oasis?

By Franklin Everett Shaw

Is your Vegas home making you sick? You might not even realize it. Sick Building Syndrome (SBS) is a real problem, and it’s often lurking undetected in our homes, especially here in the desert.

It’s more than just allergies. SBS encompasses a range of symptoms, from headaches and fatigue to respiratory issues and skin irritation, all linked to the time spent inside a particular building.

Las Vegas presents unique challenges. The intense heat, dry air, and specific building materials used here create a perfect storm for indoor air quality problems.

Let’s dive into how to identify and combat SBS in your Las Vegas home.

First, understand the culprits. Mold, volatile organic compounds (VOCs), and poor ventilation are the primary offenders.

Mold thrives in unexpected places. Think beyond leaky pipes; your HVAC system is a prime breeding ground, especially with the constant temperature fluctuations.

VOCs are released from building materials. New carpets, paints, and even furniture emit these chemicals, and the desert sun intensifies the off-gassing process.

Poor ventilation traps these pollutants. Tightly sealed homes, designed for energy efficiency, can inadvertently create unhealthy indoor environments.

So, how do you know if you have SBS? Pay attention to your symptoms.

Do you feel better when you leave your house? That’s a big red flag.

Are your symptoms worse during certain times of the year? This could indicate seasonal mold growth or increased VOC emissions due to heat.

DIY testing is a good starting point. You don’t need expensive lab equipment to get a sense of your indoor air quality.

Mold test kits are readily available at hardware stores. These kits typically involve collecting a sample and sending it to a lab for analysis.

Look for kits that test for a wide range of mold species. Some molds are more toxic than others.

VOC monitors are another useful tool. These devices measure the levels of VOCs in your air in real-time.

Consider purchasing an air quality monitor that tracks multiple pollutants. These devices often measure particulate matter, carbon dioxide, and humidity in addition to VOCs.

Now, let’s talk about remediation. Addressing SBS requires a multi-pronged approach.

Start with ventilation. Open windows and doors whenever possible, especially during cooler hours.

Install exhaust fans in bathrooms and kitchens. These fans help remove moisture and pollutants from the air.

Upgrade your HVAC system’s air filter. Look for a filter with a high MERV rating (Minimum Efficiency Reporting Value).

A MERV 13 filter or higher is recommended for capturing small particles like mold spores and pollen.

Clean your HVAC system regularly. This includes cleaning the coils, drain pan, and air ducts.

Consider hiring a professional HVAC technician for a thorough cleaning. They have the equipment and expertise to remove stubborn mold and debris.

Address moisture problems promptly. Fix any leaks in your roof, plumbing, or foundation.

Use a dehumidifier to control humidity levels. Aim for a humidity level between 30% and 50%.

Choose low-VOC building materials and furnishings. Look for products that are certified by organizations like GreenGuard.

Air out new furniture and carpets before bringing them inside. This allows some of the VOCs to dissipate outdoors.

Houseplants can help improve indoor air quality. Certain plants, like snake plants and spider plants, are particularly effective at removing pollutants.

Avoid using harsh cleaning chemicals. Opt for natural cleaning products whenever possible.

Baking soda, vinegar, and lemon juice are effective and non-toxic cleaning agents.

Be mindful of your landscaping. Overwatering can create damp conditions that promote mold growth.

Ensure proper drainage around your foundation. This will help prevent water from seeping into your home.

Consider the impact of your pool. Evaporation can increase humidity levels indoors, especially if your pool is located close to your house.

Use a pool cover to reduce evaporation. This will also help conserve water.

Las Vegas homes often have stucco exteriors. Stucco can crack and allow moisture to penetrate the walls, leading to mold growth.

Inspect your stucco regularly for cracks and repair them promptly. Use a sealant that is specifically designed for stucco.

Pay attention to your garage. Garages are often poorly ventilated and can accumulate VOCs from cars, lawn equipment, and other stored items.

Ensure your garage is properly ventilated. Open the garage door periodically to air it out.

Store chemicals and paints in airtight containers. This will help prevent VOCs from escaping into the air.

Common mistakes to avoid: Ignoring the problem. SBS won’t go away on its own.

Masking the symptoms with air fresheners. Air fresheners often contain VOCs that can worsen the problem.

Over-relying on air purifiers. Air purifiers can help, but they are not a substitute for addressing the underlying causes of SBS.

Failing to identify the source of the problem. You need to find and eliminate the source of the pollutants to effectively combat SBS.

Here’s a step-by-step guide to tackling SBS in your Vegas home:

1. Assess your symptoms and identify potential sources of pollution.
2. Conduct DIY testing to measure mold and VOC levels.
3. Improve ventilation by opening windows and using exhaust fans.
4. Upgrade your HVAC system’s air filter and clean the system regularly.
5. Address moisture problems and control humidity levels.
6. Choose low-VOC building materials and furnishings.
7. Use natural cleaning products and avoid harsh chemicals.
8. Monitor your progress and adjust your strategies as needed.

Long-term health and wellness are the ultimate goals. Creating a healthy indoor environment is an investment in your well-being.

Don’t underestimate the impact of SBS. It can significantly affect your quality of life.

Take action today to identify and combat SBS in your Las Vegas home. Your health is worth it.
