Repairing joints with modern methods or mismatched mortar can significantly alter the home's appearance, even if the repair is structurally sound. For example, repairing a historic brick wall with wider, brighter, or rougher mortar joints instead of matching the original narrow, finished joints creates visible lines that disrupt the masonry’s appearance.

Historic masonry restoration is more than repairing damaged brick, stone, or mortar. It is the process of restoring older masonry so the finished work protects the home, matches the original materials, and preserves the character.
