Step-by-Step

Wear gloves and goggles during this process. Chip out the damaged brick one piece at a time. Remove the old mortar, too. Thoroughly clean out dust and debris from the cavity.

Dampen the surrounding bricks to retard water absorption from the mortar, then lay fresh mortar on the bottom and sides of the cavity.

Wet the brick, mortar its top, slide it into place, and pack mortar into the joints. Scrape off excess mortar.

Match existing joints with the proper technique. Use a mason's jointer or a piece of pipe.
