How to Kill Mold on Walls – The Most Effective Ways

Mold is a common problem for many homeowners and can often be found on the walls of your home. Mold thrives in moist environments, such as bathrooms, kitchens and basements.

If you have mold on your wall, don't worry! This blog post will teach you how to get rid of mold in the simplest ways!

The Differences Between Mold and Mildew

Mold is a thick, hairy fungus that feeds on damp surfaces. Mildew is different in the sense that it only grows on dry surfaces such as bathroom tiles or shower curtains. It spreads quickly and easily so catching it early can save you time, money and your sanity!

Signs of Mold on Your Walls

Mold is a problem that can often go unnoticed. To find out if you have mold on your walls, check for the following:

  • Brownish or black spots on the surface of objects inside (especially tiles)
  • Rotten, musty smell in certain areas such as bathrooms and kitchens
  • Must be moist to create mold so look for damp surfaces like moisture stains in the corners of your ceiling
  • Musty odor and taste to food that has been stored or prepared in areas with mold growth.
  • Allergic and sickness symptoms such as sneezing, stuffy nose, itchy eyes, dizziness or headaches.

What Causes Mold on Walls?

Mold grows from spores found in nature, such as rainwater. If you have a leak or wet spot inside your house where mold could grow, it will spread quickly.

To avoid this problem altogether and to keep your home healthy for everyone living there, fix any leaks or replace any rotting wood that may be in the house.

Potential Health Risks of Mold

Mold is a hidden enemy! It can cause asthma in children and allergic reactions for some people. If you or someone living with you has allergies to mold, keep an eye out for the following symptoms:

  • Hives
  • Wheezing
  • Itching eyes
  • Nausea, abdominal pain
  • Coughing
  • Headaches
  • Fatigue and listlessness. 

If you experience any of these symptoms after noticing mold on your walls, seek medical attention immediately! Mold can spread quickly to other parts of the house and is very difficult to clean out if it isn't caught in time.

After getting rid of visible mold, you have to take some necessary actions to keep them at bay. To keep mold away and to prevent it from coming back, follow these tips:

  • Keep the area where you live free of any moisture. Keep your home well ventilated and dry to prevent mold growth.
  • Use a dehumidifier to remove any excess moisture from the air in your home and make sure it is well ventilated.
  • Keep your windows open in living quarters as much as possible, especially in humid climates.
  • Cover any porous materials with plastic or throw them out if they are infected.
  • Do not store any foods in your kitchen that would be affected by mold. If you have any foods that are affected, discard them and clean out all of the cupboards as well.
  • Throw away any clothes or bedding that has mold on it.
  • Keep any items in your basement away from the walls as this is where condensation will collect.
  • Clean the inside of your fridge and freezer regularly to remove any mold or bacteria that may be present. Do not leave anything more than a week old in your freezer or fridge.
  • If you live by the coast, do not store any wooden items near windows as saltwater will cause the wood to rot and create a moist environment for mold.
  • Use the right detergents and dryer sheets. Mold can grow on clothes that have been washed or dried incorrectly.
  • If you see any mold anywhere in your home, be sure to clean it up right away. If not addressed, the mold will only get worse and can spread throughout your home!

How to Get Rid of Mold on Different Types of Walls

Remove the mold by brushing it with a dry brush or scraping it off. You can also use a small amount of bleach diluted in water to kill the mold and then rinse well. If you have an abundance of mold, consider hiring professionals who specialize in removing this pesky substance from your walls.

Use a mild detergent and water to remove the mold. If it returns, use a bleach solution on small areas of cement and rinse well with warm water afterwards.

Painted Walls:
Cover the surface in baking soda/vinegar paste (equal parts) for about an hour before scrubbing off with a sponge or cloth.

Cement Tiles:
Mix a solution of bleach and water in a bucket to clean the mold. Rinse well with warm water afterwards.

In conclusion, getting rid of mold is a tough process that requires patience and hard work. But the results are well worth it!

Keep your home dry and clean to prevent mold growth by using dehumidifiers or opening windows for ventilation in high-moisture areas like bathrooms and kitchens. If you have a leak, fix it before the problem gets worse!

My name is Justin Williams. I am the founder and blogger at (read more about us). I was an allergy sufferer and that is also the reason why I began my trek to finding the best dehumidifier for my own personal health issues. All of the dehumidifier top picks on the site were put through their paces by Lance Perez - our dehumidifier researcher. He put each one through a series of tests to see how well they performed. Then, our editorial team compiled the insights into articles and published them.
