Home Restoration - Benjamin Baker - September 30, 2023

“How dangerous is mold in a house?” is a question that deserves careful attention. While many dismiss mold as a mere cosmetic issue, it’s more than an unpleasant sight on walls or ceilings. In reality, mold lurking in our homes can have significant health implications for those living inside. Beyond the health concerns, the presence of mold can also devalue a property and lead to costly repairs if not addressed promptly. 

Everyone deserves to live in a safe environment, and understanding the dangers of mold is the first step towards achieving that. As homeowners and renters, it’s our responsibility to stay informed and proactive in maintaining the sanctity of our homes. Dive deeper into this article to fully understand the dangers of mold and learn effective strategies for prevention and remediation.

How Can Mold Enter Your Home?

Mold spores are everywhere in the environment and can enter homes in several ways:

  • Windows and Doors: Every time you open a window or door, mold spores can drift in, especially during humid days.
  • Ventilation Systems: HVAC systems, if not regularly cleaned, can circulate mold spores throughout your home.
  • Clothing and Pets: Been out for a walk? Your clothes or your pet’s fur can carry mold spores back inside.
  • Foot Traffic: People coming in and out can track spores on their shoes.
  • Damp Areas: Any water intrusion, like leaks from the roof or plumbing, can provide an ideal environment for mold growth. They don’t just need water; a little moisture from a humid day can suffice.

Remember, mold doesn’t need a grand invitation. A tiny water leak or just a bit of dampness can offer mold spores the perfect home.

The Risks of Exposure to Mold

How dangerous is mold in a house? Mold isn’t just an unsightly blotch on your wall; it’s a potential health hazard:

  • Respiratory Issues: Breathing in mold can lead to coughing, wheezing, and, in some cases, the onset of asthma or exacerbation of existing asthma.
  • Allergic Reactions: Mold can trigger sneezing, itching, and a runny nose in those allergic to it.
  • Weakened Immunity: For people with compromised immune systems, mold exposure can bring more severe reactions, even fungal infections.
  • Skin Irritations: Direct contact can result in rashes for some individuals.
  • Eye and Throat Discomfort: Mold can cause watery eyes and sore throat, making your living space uncomfortable.
  • Long-term Health Risks: Constant exposure might lead to chronic respiratory illnesses or other long-term health concerns.

Symptoms of Mold Exposure

Mold, while tiny, can have a colossal impact on our health. Its effects vary from person to person, but there are some common symptoms that people exposed to mold might experience:

Shortness of Breath

Breathing becomes a challenge when mold spores enter the respiratory system. For some, it might feel like an invisible weight on their chest, making it hard to draw a full breath. This isn’t just discomfort; it’s your body reacting to foreign invaders.

Asthma Attacks and Asthma Symptoms

Imagine an asthma sufferer’s airways as sensitive alarms. When mold spores are present, it’s like setting off these alarms, leading to inflammation and constriction. This can result in wheezing, coughing, and, in severe cases, asthma attacks that require immediate medical attention.

Allergic Reactions and Memory Loss

Mold spores are allergens. When they enter our system, our body might respond with itching, redness, sneezing, and even hives. But mold doesn’t stop at just triggering allergies. Over time, if you’re constantly breathing in these spores, it can cloud your thinking. Some people report forgetfulness, difficulty concentrating, and, in rare cases, more significant memory issues.

Lung Infections and Other Health Issues

For those with already weakened immune defenses, like the elderly or those with chronic illnesses, mold is an even bigger threat. The spores can settle in the lungs, leading to infections. Beyond the respiratory system, mold exposure can cast a wide net of symptoms, from persistent headaches and fatigue to dizziness. It’s like the body’s constant alarm signal that something’s not right.

Diagnosing a Mold Problem in Your Home

Understanding how to diagnose the presence of mold in your home can be your shield against its harmful effects. Here’s a deeper look into how you can ascertain whether mold has made a home within yours:

Visual Inspection for Water Damage or Leaks

Often, mold begins its invasion in areas where water has made an unwelcome appearance. Damp spots, water stains, or even unusual discoloration on walls, ceilings, and floors can be telltale signs that you need water damage restoration services. But it’s not just the sight; sometimes, the nose knows. If there’s a persistent musty odor, especially in areas like basements or bathrooms, it’s a red flag indicating possible mold growth.

Use a Moisture Meter to Test the Humidity Levels

Mold thrives in moist environments. While we might not always notice it, our homes can sometimes become unintentional greenhouses for mold growth, especially if the humidity levels rise. Investing in a moisture meter can be beneficial. These devices measure the amount of moisture in the environment. If you find that your home’s humidity levels regularly exceed 60%, it might be time to consider dehumidifiers or other measures to keep mold at bay.

Hire a Professional Inspector to Identify the Type of Molds Present

Not all molds are created equal. While some might cause mild allergies, others can be severely detrimental to health. By hiring a professional, you’re ensuring a thorough inspection of your space. They come equipped with the right tools and knowledge to pinpoint exactly where the mold is, identify its type, and offer guidance on the best course of action to remediate it. Remember, taking quick action can save not only your home’s structure but also safeguard the health of everyone living inside.

Removing Dangerous Molds from Your Home

The menace of mold isn’t something to be taken lightly. Its impact on health and home structures makes it imperative to act swiftly. Addressing mold isn’t just about aesthetics; it’s about creating a safe and breathable environment for all. Here’s a more detailed look at how you can tackle mold infestations in your home:

Identifying the Extent

Before diving into cleaning, it’s vital to determine the extent of the mold infestation. A surface inspection might reveal mold in visible areas, but sometimes, mold hides behind walls, under carpets, or in other hidden crevices. Shine a flashlight and do a thorough check, especially in damp areas of your home.

DIY Cleaning for Small Areas

For mold that covers a small area (less than about 10 square feet), many homeowners choose to handle the job themselves. Using a mixture of water and detergent, scrub the mold off hard surfaces, making sure to wear protective gloves and a mask. Once cleaned, it’s crucial to ensure the area is dried thoroughly, preventing any future mold growth.

Beware of Toxic Mold

Not all mold types are the same. Some, like Stachybotrys chartarum, commonly known as black mold, can be toxic and require careful handling. If you suspect the presence of toxic mold, it’s best not to disturb it yourself, as the spores can become airborne and pose respiratory risks.

Professional Remediation

In cases of extensive mold growth or if toxic mold varieties are suspected, it’s time to call in the experts. Professional mold remediators come equipped with specialized equipment and knowledge to safely and thoroughly remove mold infestations. They will not only remove the mold but also address the root cause, ensuring that conditions unfavorable for mold growth are established.

Prevention is Key

After addressing the immediate mold problem, it’s essential to focus on prevention. This might involve fixing leaks, ensuring proper ventilation, using dehumidifiers, or applying mold-resistant products to susceptible areas.

While mold removal can be a daunting task, with the right approach and awareness, you can ensure your home remains a safe haven, free from the threats of dangerous molds.
