What you will need

When cleaning the mold off of your bricks it is important to possess the proper equipment for the job but also to keep yourself clean and away from sickening contaminants. For this job you will need; goggles, rubber gloves, a firm broom, bucket with bleach and water and a hose and nozzle for rinsing.

Here are the steps you can follow at home:

  • Step 1: Mix 1 part bleach and 4 parts water in a bucket
  • Step 2: Put on safety equipment (gloves & goggles)
  • Step 3: Scrape the existing mold off of the bricks as best as possible
  • Step 4: Apply the bleach and water to the brick
  • Step 5: Let it sit for the day or overnight
  • Step 6: Rinse the wall and check for progress
  • Step 7: Repeat the process to ensure spores are all gone!

If you clean the mold or moss off of your brick walls and you still notice traces of black in the holes of the brick, use more bleach and water, repeat the process and let it sit for a longer period of time. If you have completed this process a few times to no avail, contact Steamatic at

What to look out for during the cleaning process:

When you are working on removing mold from your brick walls it is important that you take the proper precautions. Damages such as the brick color fading can occur if you use a power washer on the face of the brick. Sometimes, when attempting to remove mold from the bricks of your home you will find a white film like material, this is called efflorescence which is caused by excessive moisture endured by the bricks over time.  

Taking the time to clean your bricks and working to avoid mold growth, is a great way to ensure the safety and well-being of members in your household. As time goes on and mold builds up it becomes more difficult to remove.

Often times, it takes the work of professionals such as ourselves at Steamatic to complete this brick cleaning process for you in the most cost-effective way possible!
