How to Get Rid of Black Mold on Exterior Brick

Kimbry Parker

Black mold on an exterior brick surface is unsightly. Whether the mold growth is on your brick patio or the exterior of your home, it’s important to tackle the problem promptly so it doesn’t spread. Remove mold from brick the right way so you get rid of it without damaging the brick in the process.

Brick that isn't exposed to much sunlight is more suseptible to mold growth.
  1. Cover surrounding plants, foliage and landscaping with plastic sheeting. The cleaning solution used to remove black mold can harm or kill them.

  2. Fill a bucket with equal parts chlorine bleach and water.

  3. Dip a stiff scrub brush into the solution. Scrub the moldy spots on the brick vigorously with the brush and bleach. Rinse the scrub brush in the bleach solution frequently.

  4. Let the bleach sit on the moldy spots of brick for about two hours. Rinse the brick thoroughly with water from the garden hose.

  5. Tip

    More than one application of the bleach mixture may be necessary to remove all of the black mold.


    Wear protective eyewear, old clothing and rubber gloves when using chlorine bleach.
