A wall with sticky notes on myths and facts.

Mold. It's a four-letter word that can strike fear into the heart of any homeowner. And with that fear often comes misinformation and confusion. While you can ask for information from people you know, it's difficult to separate fact from fiction. While you can find much information online, the internet can also be a breeding ground for myths and misconceptions, and mold is no exception.

As the South Arkansas experts in mold remediation, we at the Restore-It team are familiar with homeowners' fears about mold. And with good cause, in over a decade of experience helping our neighbors deal with mold, we have seen how much damage mold can cause in a relatively short time. But today, we ask you to move beyond fear and step into the reality of household mold like a true expert.

In other articles, we have discussed the hidden risks of mold in homes and why it's best not to postpone mold remediation. This time, we will explore the most common myths regarding household mold. From what kind of cleaning solutions are actually a bad idea to the reality of mold growth. So, let's clear the air (literally!) and debunk some of the most common mold myths circulating around South Arkansas homes.

Myth #1: A Little Mold is No Big Deal

It's true that we encounter mold spores daily in the air we breathe, as they are a part of the natural environment. It's also true that small amounts of mold might not cause immediate health problems for everyone. However, ignoring even minor mold growth is like ignoring a small leak in your roof. It might seem insignificant initially, but it can lead to much bigger problems over time.

Mold can spread quickly, and even seemingly harmless species can trigger allergies, asthma, and other respiratory issues in sensitive individuals. The key takeaway? Don't dismiss any mold growth in your home. Address it promptly to prevent it from becoming a bigger issue.

Myth #2: Bleach Kills Mold – Problem Solved!

Ah, bleach. The go-to cleaning solution for many homeowners. But bleach is not the magic bullet you might think it is when it comes to mold. While bleach can kill mold spores on non-porous surfaces like tile or countertops, it's far less effective on porous materials like wood, drywall, and insulation. Why? Because bleach only kills surface mold. It can't penetrate porous materials to reach the mold's roots, which means the mold can easily grow back. Plus, bleach can actually damage certain materials and release harmful fumes.

If you are dealing with a big mold patch (larger than 10 square feet), it's best to leave it to the professionals. However, if you instead have a smaller mold problem, you can try some of our recommended DIY cleaning solutions. They are easy-to-find ingredients that can help you remove the mold while being gentler to your building materials.

Myth #3: All Mold is Black and Toxic

This is a common misconception. While "black mold" (Stachybotrys chartarum) can produce toxins, not all mold is black or toxic. Mold comes in various colors: green, white, gray, and even pink! The color of the mold doesn't necessarily indicate its toxicity. However, any significant mold growth, regardless of color, should be addressed promptly to prevent potential health risks and property damage.

Myth #4: Mold Only Grows in Dirty Homes

This one is simply not true. Mold doesn't discriminate. It can grow in any home, regardless of how clean it is. All mold needs is moisture and a food source (organic material). Even the cleanest homes can have hidden moisture problems, like leaky pipes, condensation, or poor ventilation, creating the perfect mold growth environment. Regular cleaning and good hygiene practices can help reduce the risk of mold, but they can't completely eliminate it.

Myth #5: I Can Handle Mold Remediation Myself

There is undoubtedly a space for DIY methods when addressing small, surface mold problems. However, larger mold patches (over 10 square feet) are best left to professionals. Mold remediation requires specialized knowledge, equipment, and safety precautions.

Professionals can accurately assess the extent of mold growth, identify the species involved, contain the affected area, and safely remove the mold while addressing the underlying moisture problem. Misguided attempts at DIY mold, especially in larger infestations, can be risky and even worsen the problem.

Myth #6: Mold Remediation is Too Expensive

The cost of mold remediation can vary depending on the extent of the problem, but ignoring mold growth will always be more expensive in the long run. Mold can cause significant damage to your home, leading to costly repairs or even replacement of structural components. Plus, mold-related health problems can result in medical expenses and lost productivity.

Addressing mold promptly with professional remediation can save you money and protect your health in the long term.

Myth #7: Painting Over Mold Will Make It Disappear

Out of sight, out of mind, right? Wrong! Painting over mold is like putting a band-aid on a broken bone. It might temporarily conceal the problem but won't address the underlying issue. Mold can easily grow through paint, especially if the moisture problem hasn't been resolved. In fact, painting over mold can actually trap moisture and make the problem worse. Addressing mold growth and moisture issues before repainting will save you from future headaches.

Myth #8: Mold Only Grows in Visible Places

Think mold only grows where you can see it? Think again! Mold loves hiding in dark, damp places, like behind walls, under floors, and in crawl spaces. Just because you can't see it doesn't mean it's not there.

If you notice a musty odor, water stains, or other signs of moisture, there's a good chance mold is lurking nearby. A professional mold inspection can help identify hidden mold growth.

Myth #9: Air Fresheners Eliminate Mold Odors

That "spring fresh" scent might mask the musty odor of mold, but it won't eliminate the mold itself. Air fresheners simply cover up the smell; they don't address the underlying problem. If you notice a persistent musty odor in your home, don't just mask it – investigate the source and address mold growth.

Myth #10: Mold Will Always Come Back

While it's true that mold can be persistent, it doesn't mean you're doomed to a life of moldy misery. Proper remediation and moisture control measures can significantly reduce the risk of recurring mold growth.

This might involve fixing leaks, improving ventilation, and addressing structural issues contributing to moisture accumulation. A professional mold remediation company can help you identify and implement effective prevention strategies.
