The small sash at the watchtower level were replaced in 1916 after only 22 years of service. The original frames remained in place. The original configuration was 4 over 4 and then changed to a 1 over 1. No record has surfaced as to explain the change.
These current sash have multiple problems but no rot. The main issue being the inappropriate placement of utilities through the main members of the sash.
Before I started the repairs all the sash were documented and photographed and a paint sample was taken. Then they were off to have all the paint removed.

After I retrieved the sash from the paint removal company I could see right away why there was not rot. All the sash are made from Western Red Cedar which is naturally decay and insect resistant. The damage from the utility holes is very extensive. Especially through the main joint of the north top sash.
