Vegas Mold: Did Your New Home Hide Radon and Sick Building?
By Franklin Everett ShawThe closing papers are signed, the keys are in your hand, and you’re finally a homeowner in the dazzling Las Vegas valley! But before you start planning that pool party or converting the spare room into a home theater, there are a few invisible threats you need to be aware of: mold and radon. These silent invaders can contribute to “sick building syndrome,” turning your dream home into a health hazard. This guide is your step-by-step roadmap to identifying and addressing these issues, specifically tailored for new homeowners in Las Vegas, Summerlin, and Henderson, Nevada.
First, let’s understand what we’re up against. “Sick building syndrome” (SBS) is a collection of symptoms linked to time spent in a particular building. These symptoms can include headaches, fatigue, eye, nose, and throat irritation, and even skin rashes. Mold and radon are two common culprits, but poor ventilation, chemical contaminants, and even inadequate lighting can also contribute.
Radon is a colorless, odorless, radioactive gas that occurs naturally from the breakdown of uranium in soil, rock, and water. It can seep into homes through cracks in the foundation, gaps around pipes, and other openings. Long-term exposure to radon is the second leading cause of lung cancer in the United States, according to the EPA. Nevada, including Las Vegas, is considered a moderate radon risk area.
Mold, on the other hand, thrives in damp environments. Leaky pipes, poor ventilation, and even high humidity can create the perfect breeding ground for mold growth. Mold spores are everywhere, but they only become a problem when they find a suitable place to multiply. Certain types of mold can produce allergens and irritants, leading to respiratory problems and other health issues.
So, how do you protect your family and your investment? Let’s start with radon testing. The EPA recommends that all homes be tested for radon. Fortunately, DIY radon test kits are readily available at most hardware stores in the Las Vegas area, including Lowe’s and Home Depot. These kits typically involve placing a detector in the lowest livable level of your home for a specified period (usually 2-7 days). After the testing period, you mail the detector to a lab for analysis.
Follow the instructions carefully. Placement is crucial. Avoid placing the detector near drafts, windows, or exterior walls. Also, keep windows and doors closed as much as possible during the testing period to get an accurate reading.
If your DIY test comes back with a radon level of 4 picocuries per liter (pCi/L) or higher, the EPA recommends taking action to reduce radon levels. This is where professional radon mitigation comes in. Several reputable radon mitigation companies serve the Las Vegas area. Look for companies certified by the National Radon Proficiency Program (NRPP) or the National Radon Safety Board (NRSB).
A common mitigation technique is sub-slab depressurization. This involves installing a pipe through the foundation and using a fan to draw radon gas from beneath the slab and vent it safely outside. The cost of radon mitigation can vary depending on the complexity of the system, but it typically ranges from $800 to $2500.
Now, let’s move on to mold. Unlike radon, mold is often visible or detectable by its musty odor. However, hidden mold growth can be a challenge to find. Start by inspecting areas prone to moisture, such as bathrooms, kitchens, basements (if applicable), and around plumbing fixtures. Look for water stains, discoloration, or visible mold growth on walls, ceilings, and floors.
Pay close attention to areas that may have experienced water damage in the past. Even if the water damage has been repaired, mold can still linger if the area wasn’t properly dried and cleaned. In Las Vegas, air conditioning systems are running almost constantly, so check around AC units and ductwork for condensation and potential mold growth.
If you suspect mold growth but can’t find the source, consider hiring a professional mold inspector. Several companies in Las Vegas specialize in mold detection and testing. They use specialized equipment, such as moisture meters and thermal imaging cameras, to identify hidden moisture and mold growth. They can also take air samples to determine the type and concentration of mold spores present in your home.
DIY mold test kits are also available, but they are generally less accurate than professional testing. These kits typically involve collecting a surface sample or an air sample and sending it to a lab for analysis. However, DIY kits can only identify the type of mold present, not the extent of the mold growth.
If you find mold growth, it’s important to address it promptly. Small areas of mold (less than 10 square feet) can often be cleaned yourself using a bleach solution (1 part bleach to 10 parts water). Always wear gloves, a mask, and eye protection when cleaning mold.
For larger areas of mold growth, it’s best to hire a professional mold remediation company. Mold remediation involves not only removing the mold but also addressing the underlying moisture problem that caused the mold to grow in the first place. This may involve repairing leaks, improving ventilation, or dehumidifying the affected area.
Be wary of companies that offer mold remediation services without addressing the underlying moisture problem. If the moisture problem isn’t fixed, the mold will likely return. Also, be sure to check the company’s credentials and insurance before hiring them.
A common mistake new homeowners make is ignoring minor water leaks. A small drip under the sink or a slow leak in the roof can create the perfect environment for mold growth. Address these issues promptly to prevent them from escalating into larger problems.
Another pitfall is relying solely on visual inspections. Mold can grow behind walls, under floors, and in other hidden areas. If you suspect mold growth, don’t hesitate to hire a professional inspector to conduct a thorough assessment.
Finally, remember that ventilation is key to preventing mold growth. Make sure your home is properly ventilated, especially in bathrooms and kitchens. Use exhaust fans when showering or cooking, and open windows regularly to allow fresh air to circulate. In the dry Las Vegas climate, consider using a humidifier during the winter months to prevent your home from becoming too dry, which can also contribute to health problems.
By taking these steps, you can protect your family from the dangers of mold and radon and ensure that your new home in Las Vegas, Summerlin, or Henderson is a healthy and comfortable place to live. Don’t let these invisible threats steal your peace of mind. Take action today to create a safe and healthy home for years to come.
