East Elevation Undergoes Final Repointing

Phase 2 stonework repair continues as Joseph Gnazzo Company Inc. turns their attention back to the main East elevation. Here they are using a bucket lift to do spot repointing on all remaining areas of the East wall. Repointing is the process of renewing the pointing, which is the exterior part of mortar joints. Over time, weathering and decay cause voids in the joints between the granite blocks, allowable undesirable entrance of water. Repointing will ensure a water-tight exterior. As the new mortar ages over time, its color will blend in to match the older mortar.
