A condition assessment was prepared in 2003 by the National Park Service which was used to prepare detailed cost estimates. The church contains its original iconostasis and many original nineteenth century icons. These irreplaceable relics are threatened by a failing roof and foundation, inadequate temperature control and fire. The restoration of St. Sergius will be costly and logistically challenging due to its remote location. Materials for the work must be barged in three months in advance to prepare for a summer project.
