Step 1 Prepare the Area for Washing
You’ll need to repair any cracks in your bricks or mortar before using a pressure washer on the required surface. Make sure to cover and protect light fixtures, electrical outlets and jacks with a waterproof material as you don’t want water to penetrate and harm them. Also, be sure to cover nearby shrubs, bushes and flower beds and ensure that your windows are closed so no water gets into your home. You may want to have a professional opinion before pressure washing brick that is older, as they may not stand up to the pressure from the washer.
