In the summer of 2014, Plymouth Church began a project to renovate the sanctuary. The chief concern of the project was to replace the original pipe organ that had been damaged during the 6.8 Nisqually earthquake that hit the Puget Sound region at 10:54 am PST (18:54 UTC) on Ash Wednesday, February 28, 2001. The organ has been replaced with a new tracker organ, Opus 140, built and installed by C.B. Fisk Inc. in Gloucester, Massachusetts. The renovation project also involved repairing major structural damage to the Nave's roof trusses. It addressed acoustical problems with the space and saw the installation of a new energy-efficient lighting system. The new organ was inaugurated with a series of concerts in fall/winter 2015-16.
