Understanding the Enemy: Where Does Mold Come From and Why Eliminate It?

Before you grab your cleaning supplies, first you must understand what you're up against. This section explains where mold originates, why it thrives in certain conditions, and, most importantly, why it needs to be eliminated from your home.

You see, mold is everywhere. As a natural part of our environment, it plays a vital role in breaking down organic matter. Mold spores are constantly floating in the air, both indoors and outdoors. The problem comes when mold spores land on a damp surface and find the right conditions to grow. The conditions for mold growth are moisture, a food source (like wood, drywall, or even dust), and a suitable temperature.

So, why is eliminating mold so important? Beyond the unsightly appearance and musty odor, mold can pose serious health risks. The United States Environmental Protection Agency (EPA) warns that mold can produce allergens, irritants, and sometimes toxic substances known as mycotoxins, which can impact people inhaling or touching mold or mold spores. Furthermore, mold can damage building materials, leading to costly repairs if left unchecked. Simply put, promptly addressing mold growth is essential for protecting your health and home.

Prevention is Key: Keeping Mold at Bay

The best way to deal with mold is to prevent it from growing in the first place. This involves controlling moisture levels in your home. Some tips to keep moisture levels under control are:

  • Regularly inspect areas prone to dampness, like basements, bathrooms, and kitchens
  • Fix leaky pipes and faucets promptly.
  • Use dehumidifiers in damp areas like basements and bathrooms.
  • Ensure proper ventilation by opening windows and using exhaust fans.
  • Clean and dry spills immediately.

These preventative measures will create an environment that's less hospitable to mold. By keeping a proactive and vigilant attitude, you can maintain a safe environment.

People Who Shouldn't Try to Clean Mold

We get it; you have a mold spot in your wall and want to remove it ASAP, and if so, there is a high chance you may ask for help from your family or friends. After all, the more hands, the better, right? Well, not necessarily… Certain health conditions may be exacerbated when exposed to mold during the cleanup. To avoid complications, the CDC suggests these individuals do not participate in the clean-up process:

  • Allergy-prone people. Mold can trigger allergic reactions in these individuals.
  • Immune-suppressed people or with underlying lung disease. They are at a higher risk of a fungal infection.
  • People with chronic respiratory diseases (e.g., asthma) or chronic obstructive pulmonary disease (COPD). Mold is likely to cause complications during breathing for these individuals.

How to Reduce Your Exposure to Mold If You Cannot Leave Your Home

The CDC also recommends that individuals with asthma, COPD, or compromised immune systems avoid staying in a moldy home, even during cleanup. Brushing and cleaning mold can release spores or dead mold into the environment, which may trigger reactions in these individuals. Here is how to reduce mold exposure:

  • Reduce the time spent in your home.
  • Designate a separate sleeping area. Seal the cleanest room with plastic tarps. Leave your shoes outside, refrain from bringing items from other parts of the house into this room, and avoid wearing moldy clothing.
  • Contain the mold. Seal off affected areas with plastic tarps.
  • Prevent mold from spreading throughout the house.
  • Check your HVAC system. Prevent mold from being spread.
  • Clean, discard, or seal any moldy items.

Gearing Up for Battle: Essential Mold Cleanup Supplies

Now that you know about your enemy, it's time to prepare your arsenal. Here is a list of essential supplies you will need for safe and effective mold removal:

  • Respirator mask (N95 or higher).
  • Gloves (non-latex).
  • Protective eyewear.
  • Scrub brushes and sponges.
  • Buckets or mixing bowls for the cleaning solutions.
  • Trash bags (heavy-duty).
  • Sealable containers or bags.

Choose Your Weapon: Effective DIY Mold Cleaning Solutions

With your safety gear on and supplies at the ready, it's time to choose your cleaning solutions. Several household solutions can be effective against mold:

  • Borax: This natural mineral inhibits mold growth and is recommended by many mold removal experts. Mix one cup of borax with a gallon of warm water. Spray the solution onto the mold, gently scrub it with a brush or sponge, and wipe it with a clean cloth. Do not rinse.
  • Vinegar: Undiluted white vinegar can be used in a spray bottle. Sprinkle some of the solution on the mold and let it sit for at least an hour. If mold remains, mix one teaspoon of baking soda with two cups of water and spray the area. Let it sit for a few minutes, then scrub it with a brush. Repeat if necessary. Once you are done, wipe the area with a clean cloth.
  • Baking Soda: This alkaline compound, which is excellent for absorbing moisture and odors, can be used as a paste or a spray solution. To make a paste, combine equal parts of baking soda and water in a bowl, apply it directly onto the affected area until it's dry, and then scrub the area until the mold is removed. If you prefer a spray, mix 2 tablespoons of baking soda with 2 cups of water, shake the bottle, apply it to the spots, and scrub away.
  • Hydrogen Peroxide: This powerful antiseptic is effective on porous and non-porous surfaces. Use a 3% solution and spray directly onto the area. Let it sit for 15 minutes, then wipe with a clean cloth. Repeat as necessary.

Once you are done cleaning, remember to dispose of any moldy materials properly. Place all moldy items in sealed bags. Also, thoroughly clean your gloves, brushes, and other cleaning tools to prevent further spread.

When to Get Professional Mold Remediation Services

While DIY mold cleanup can be effective for small mold spots, there are situations where professional help is necessary. Let's look at the signs indicating it's time to call in the experts.

  • Large Infestations: If the mold covers a large area (more than 10 square feet), it's best to consult a professional.

  • Recurring Mold Problems: If mold keeps returning despite your efforts, an underlying moisture issue may require professional attention.

  • Health Concerns: If you or your family members are experiencing health problems that you suspect are related to mold exposure, consult a doctor and a mold remediation specialist.

  • Hidden Mold: If you suspect mold behind walls or in other inaccessible areas, you will need the help of professionals.

You may feel anxious after discovering a mold spot on your wall or ceiling. However, with the right approach, you can effectively address this issue. By understanding mold and the importance of eliminating it, as well as the considerations for cleaning, you are now prepared to tackle the mold yourself.
