Mold can be a huge problem in homes and businesses. Not only is it unsightly, but it can also be dangerous to your health. In this guide, we will discuss how to get rid of black mold on walls. We will cover the causes of black mold, the symptoms of black mold exposure, and how to remove black mold safely and effectively.

Why should you get rid of black mold?

Black mold is a toxic and hazardous type of fungus that can cause serious health problems and allergic reactions such as respiratory issues, headaches, and skin irritation. Since it thrives in warm environments, it primarily grows in homes, especially in areas that are constantly exposed to moisture. In places where there are leaks or flooding in the house, black mold usually starts to grow on the walls.

Signs of black mold on walls

The most common signs of black mold on walls are:

  • Discoloration: Black mold usually appears as greenish-black or brownish-black patches on the wall.
  • Staining: Black mold can also cause staining of the wallpaper or paint.
  • Peeling: If the black mold is severe, it can cause the wallpaper or paint to peel off the wall.
  • Musty smell: One of the most telltale signs of black mold is a musty smell in the room.


The first step to getting rid of black mold on walls is to identify it. Black mold often looks fuzzy and blotchy, but it can also appear as patches of black or brown, which may increase and multiply over time. Because the spores are airborne, black mold can also be found in small cracks and crevices that provide moisture.

How to get rid of black mold on walls

Put on your safety gear

Once you’ve spotted black mold in your home, protect yourself with gloves, goggles, a face mask and clothes that cover your arms and legs.

Find the source of the moisture problem

The first step in getting rid of black mold on walls is to eliminate the moisture problem that allowed it to grow in the first place. Track down any leaks in your roof or pipes and fix them immediately. If there’s a leaky pipe behind a wall that has led to mold growth, you should call in a professional who can fix it without damaging your house’s structure or spreading even more spores into the air.

Clean up or replace any affected materials

Use soap and warm water to clean up any surface that has just a little bit of black mold growing on it. You can also use natural cleaners like vinegar or baking soda. If the mold is more widespread, you might need to replace the affected materials entirely.

Dry out the area completely

Once you’ve cleaned or replaced the materials, make sure to dry out the area completely. Use a fan or dehumidifier to get rid of any lingering moisture and help prevent mold from growing back.

Monitor for future growth

Even if you’ve gotten rid of all the black mold in your home, it’s important to keep an eye out for any new growth. Check for signs of mold regularly and take action immediately if you see anything suspicious.

How to get rid of black mold on walls with white vinegar

Step 1: Mix white vinegar with water in a one-to-one ratio, filling your spray bottle completely full.

Step 2: Mist the affected area thoroughly with the vinegar solution, making sure to get the edges where the wall meets the ceiling or floor. Allow the solution to sit for 30 minutes, then wipe it away with a clean rag or sponge. For tough stains, use an old toothbrush to scrub away at stubborn areas until they disappear.

Step 3: Repeat this process until all signs of mildew are gone; then spray down the area again with an equal mix of white vinegar and water to disinfect the area and prevent mold from returning.

Tips for preventing black mold on walls

  • Inspect your walls regularly for any signs of water damage, such as peeling paint or wallpaper, damp spots, or condensation.
  • If you do find any water damage, dry it out immediately and repair the source of the leak.
  • Keep your home well ventilated to prevent moisture build-up. Use exhaust fans in your kitchen and bathroom, and open up windows when possible.
  • Reduce indoor humidity with a dehumidifier, especially in rooms like basements that are prone to dampness.
  • Regularly clean areas where mold is likely to grow, such as showers, tubs, toilets, and sinks. Use a mold-resistant cleaner if necessary.
  • Fix any plumbing leaks or other sources of water as soon as possible.
  • Be sure to dry the area completely afterwards to prevent new mold from growing.



Black mold can be a serious problem in your home, but luckily there are some simple steps you can take to get rid of it. Be sure to fix any moisture problems, clean affected areas thoroughly, and dry out the area completely to prevent mold from coming back. With a little effort, you can keep your home mold-free.
