How to Remove Black Mold From a Basement


Basements are one of the best places for black mold to grow in your home because they are dark and usually humid. If you have noticed a musty smell in your basement, you might have a mold problem. Black mold can be dangerous to both pets and humans. If ingested, black mold spores can cause mold poisoning and other respiratory issues.

Things You'll Need

  • Cleaning mask
  • Rubber cleaning gloves
  • Bleach-based cleaner
  • Sponge
  • Soap
  • Broom
  • Bucket
  • Mop
  • Put on a cleaning mask and gloves before you go into your basement.

  • Go to the corners of your basement and look along the walls and floor for any traces of black mold. Black mold is a black substance that clings to walls and flooring. It will look like somebody has spread charcoal on your walls.

  • Take anything that you are storing in the basement out so you can have access to the whole room. Use a cleaner that contains bleach to kill the mold. Spray the mold down with the bleach cleaner and give it a few seconds to soak in. Use a paper towel to wipe the mold away from the walls.

  • Sweep the basement floor with a broom so get any dust or other mold spores off of the floor. Fill a bucket with hot water and pour a ½ cup of bleach-based cleaning solution into the bucket.

  • Use a mop to soak the entire floor with the cleaning solution. This will kill any remaining mold spores and help fight off the growth of mold in your basement.

  • Look at the pipes in your basement for any leaks. Mold grows in humidity. When a pipe leaks it creates humidity in the air and mold will form. Call a plumber to check your pipes or to tighten any connections that may be leaking.

Tips & Warnings

  • Always wear a mask when dealing with mold. Mold spores will cause respiratory problems if breathed in.
