3. Paint Seizure and Rattle
Years of over-painting can lead to windows being "painted shut." Alternatively, timber shrinking over a century can trigger sashes to fit loosely in their frames, causing irritating rattles throughout windy weather.

Wood Repair and Resin Splicing
Instead of replacing a whole frame, professionals use "splice repair work." Decayed areas are cut away and changed with matching seasoned timber. High-performance epoxy resins are frequently used to combine weakened wood and develop a smooth, weather-proof bond between old and brand-new lumber.
Draught-Proofing Installation

This essentially removes rattles and substantially lowers heat loss without modifying the Window Restoration Services's appearance.
Glazing Upgrades
While many select to retain initial crown glass for its "wavy" visual, others choose "slimline" double glazing.
