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.

Using lime mortar for historic natural stone or brick ensures your project has the durability, breathability, and stature of good workmanship.
