Sash Window Sill and Frame Timber Splicing

Sash Window Sill and Frame Timber Splicing

For owners of period bay windows and sashes with soft sills or crumbling pulley stiles. We rout out decayed wood back to hard grain, treat the cavity with two-part epoxy consolidant, and splice in rot-proof Accoya timber profiles. The window closes tight, keeps rain out, and keeps its original character.

Feedback from local clients

★★★★★
Two dining chairs had fractured rear legs. The team spliced new oak matching the original grain and re-glued the loose stretchers. Completely solid now.

Our walnut sideboard had deep ring marks and a split door panel. They brought it back to an even satin finish using Danish oil. Clean workmanship.
