Black mold, also known as Stachybotrys chartarum, is a common issue that can harm your property and people’s health. It is recognized by its dark greenish-black color and musty smell. Mold usually grows in damp and humid areas, often appearing on walls and other surfaces. The Mold Assassins specializes in removing and preventing mold, ensuring your home remains safe and healthy. This guide will take you through the steps to effectively remove black mold from your walls.
What Is Black Mold?
Black mold is a fungus that grows in damp, warm, and humid conditions. It is often found in bathrooms, kitchens, basements, and other areas with poor ventilation and high moisture levels. Exposure to black mold can lead to respiratory issues, allergic reactions, and other health problems.
Common Causes Of Black Mold
- High Humidity: Areas with high humidity levels are prone to mold growth.
- Water Leaks: Leaky roofs, pipes, or windows can create an attractive environment for mold to thrive.
- Poor Ventilation: Insufficient airflow can trap moisture, contributing to mold development.
Signs Of Black Mold Infestation
- Look for dark, slimy patches on walls, especially in corners or damp areas.
- A persistent musty smell is a strong sign of mold presence.
- Unexplained allergic reactions and coughing
- Respiratory issues
- Irritation in the eyes, nose, or throat can indicate mold exposure.
Test For Black Mold
At Assassins, our local experts thoroughly inspect your walls for any symptoms of mold growth. Collect a sample of the suspected mold using a cotton swab and place it in a clear plastic bag for testing.
Safety Equipments
Before beginning the mold removal and inspection, it is important to ensure the necessary safety gear to protect ourselves from mold spores and cleaning chemicals:
- N95 Respirator Mask: Use this mask to prevent inhaling mold spores.
- Gloves: Using gloves to protect your hands from fungi, mold and cleaning solutions is essential.
- Goggles: Goggles play a vital role in protecting your eyes from mold spores and cleaning chemicals.
- Long-Sleeved Clothing: To minimize skin exposure to mold and cleaning agents.
- Spray Bottle: For applying cleaning solutions.
Types Of Solution To Remove Black Mold On Walls
Various cleaners can be effective against black mold. Here are some common options:
Vinegar
Vinegar is a natural disinfectant that kills most types of molds and mildew. It’s particularly useful for smaller tiles, grout, and wood patches. Spray undiluted vinegar onto the moldy surface and let it sit for an hour before scrubbing with a brush.
Hydrogen Peroxide
Hydrogen peroxide is another excellent option. It disinfects and helps remove mold stains. Apply a 3% hydrogen peroxide solution to the mold and let it sit for 10 minutes. Then, Scrub with a toothbrush or a larger brush for bigger surfaces.
Baking Soda
Baking soda removes mold and deodorizes. Mix one tablespoon of baking soda with water to form a paste and apply it to the moldy area. Scrub with a brush, rinse with water, and dry the area.
Soap and Water
Regular soap and water can sometimes be effective, especially in less severe mold infestations. Scrub the affected area with soap and water, then rinse and dry.
5 Steps To Get Rid Of Black Mold On Walls
After gathering the essential tools and ensuring safety, let’s dive into the mold-removing steps:
Seal Off The Affected Area
Seal off the mold-infested area during cleaning with plastic sheeting and tape to prevent mold spores from spreading to other parts of your home. Contrary to the common mold myth, this method is highly effective in containing and controlling the spread of mold spores.
Prepare The Cleaning Solution
Mix a solution in a plastic bucket with one part dishwashing liquid, ten parts bleach, and twenty parts water for larger walls. For smaller mold patches, combine one tablespoon of dishwashing liquid, half a cup of chlorine bleach, and one cup of warm water in a spray bottle.
Apply The Solution to the Moldy Wall
Apply the solution using a sponge or spray bottle, starting from the bottom. To avoid damaging drywall, ensure the wall is not oversaturated. If the mold is high, use a ladder or a sponge mop to apply the solution.
Dispose of Contaminated Items
If porous items, such as paper, clothes, or fabrics, have been affected by mold, it is best to dispose of them. Clean them thoroughly with soap and water for non-porous items like plastic or metal.
Let The Wall Dry Naturally
Allow the wall to air dry completely without scrubbing or rinsing.
Inspect For Residual Stains
Once the wall is dry, check for any remaining spots or stains. If discoloration persists, repeat the cleaning process with a new batch of the solution.
Common Places Where Mold Grows
Black mold consistently grows best in damp, humid places with high moisture levels. Common places where black mold may grow include:
Bathrooms: Showers, tubs, and sinks are often places where mold grows because of the high humidity and condensation in the air.
Kitchens: Cooking produces steam and moisture that contributes to dampness, encouraging mold growth.
Basements and crawl spaces: Basements and crawl space areas are damp due to poor ventilation and moisture accumulation.
Around windows and doors: Condensation around doors and windows can be a source of moisture that can encourage mold growth, especially if these areas are exposed to moisture frequently.
Behind wallpaper: Moisture behind wallpaper or on paper items such as books or pictures can cause black mold to grow.
Walls and ceilings: Moisture accumulation on walls and ceilings from poor ventilation or a leaking roof can easily cause mold to develop.
Preventing Future Mold Growth
Your health and safety are paramount. It’s always best to make some strategies for preventing mold at home. Here, I’ve mentioned some tips to follow:
Maintain Low Humidity Levels
- Use dehumidifiers in damp areas.
- Proper ventilation in bathrooms, kitchens, and laundry rooms is needed.
