The classic look of brick makes it a popular choice for homebuilders, but dirt, grime and moss can cause discoloration over time. Pressure washing is a quick way to restore your bricks to their former beauty.

Before you pressure wash your bricks, patch damaged mortar, and allow it to dry for at least a week. Remove obstacles from the work area, cover plants and electrical components, and close windows and doors before pressure washing.

Tips for Pressure Washing Brick:

  • Brick is porous and absorbs quickly, so before you apply detergents, thoroughly soak the surface of your bricks with clear water using a delicate, low-pressure spray pattern to prevent absorption of the detergent.
  • Apply detergent from the bottom to the top, and allow it to soak for five to 10 minutes. Keep the bricks wet as needed if any areas begin to dry out.
  • Use less pressure and more detergent to clean brick.
  • Use a rotating scrub brush as needed to scour areas that are heavily soiled.
  • Rinse the detergent and residue from the top to the bottom with a low-pressure, delicate spray pattern. You might have to make several passes to clean deep stains completely.
  • If efflorescence (a white, powder-like residue) remains a problem after your house has completely dried, clean with an efflorescence remover by hand. Follow the manufacturer’s instructions.
  • When you’re done cleaning, seal your bricks with a brick and mortar sealer. Follow the manufacturer’s instructions.
