3. Paint Seizure and Rattle
Years of over-painting can lead to windows being "painted shut." Conversely, wood shrinking over a century can cause sashes to fit loosely in their frames, leading to annoying rattles throughout windy weather condition.

Lumber Repair and Resin Splicing

This practically eliminates rattles and considerably lowers heat loss without changing the window's appearance.
Glazing Upgrades
