Sash Repair in Highland Park

A damaged window sash does not always mean the entire window has to be replaced. In many cases, the sash can be repaired, rebuilt, refinished, and reinstalled while preserving the original window structure.

Rotten Window Repair provides sash repair, wood window restoration, glass replacement, and window frame repair throughout Highland Park and surrounding Chicagoland communities. Our goal is to restore the damaged part of the window whenever repair is practical.

This residential window sash repair project was completed in Highland Park, Illinois.

The window sash had visible wood deterioration and damaged areas around the frame. Instead of replacing the entire window, our team worked on the sash separately, repaired the damaged wood sections, restored the surface, refinished the frame, and prepared the sash for proper installation.

The result is a restored wooden sash with a cleaner appearance, improved structure, and preserved original window character.
