How do you anchor a brick wall that has separated from an exterior wall?

To anchor a brick wall that has separated from an exterior wall, first assess the extent of the separation and any structural damage. Use wall ties or anchors specifically designed for masonry, inserting them into the brick wall and securing them to the framing of the exterior wall. Additionally, apply a masonry adhesive between the two surfaces to help bond them together. Ensure that any repairs comply with local building codes and consider consulting a structural engineer if the separation is significant.
