Historic masonry requires specialized care that differs greatly from modern masonry practice. The wrong mortar can ruin otherwise fine brick or stone work. Shenandoah Restorations has experience with traditional masonry materials and can match the appropriate mortar to blend seamlessly into your existing brick or stone work. We can also repair or rebuild any damaged masonry.
The correct mortar is especially important when working with antique handmade bricks. Traditional brick walls are designed to breathe through the mortar joint. Modern portland-based mortars are too hard for soft wood-fired bricks, forcing moisture into the bricks themselves. Without a flexible mortar, absorbed moisture will cause the bricks to expand and crack. Moisture will also dissolve sulfites inside the brick, which can crystallize into efflorescence, causing the faces of the bricks to spall.
