2. Draughts and Thermal Inefficiency
Standard single glazing and the intrinsic spaces required for sash windows to slide efficiently result in considerable heat loss. This frequently leads to a cold living environment and high energy expenses.
3. Paint Seizure and Rattle
Years of over-painting can result in Casement Windows being "painted shut." Conversely, wood shrinkage over a century can cause sashes to fit loosely in their frames, causing annoying rattles during windy weather.

Timber Repair and Resin Splicing
Rather than changing a whole frame, specialists utilize "splice repairs." Decomposed areas are cut away and replaced with matching seasoned timber. High-performance epoxy resins are typically used to combine weakened wood and create a smooth, weather-proof bond between old and new timber.
Draught-Proofing Installation
One of the most significant upgrades throughout renovation is the installation of a detailed draught-proofing system. This includes machining grooves into the sashes or beads and inserting brush stacks or silicone seals. This virtually removes rattles and substantially decreases heat loss without changing the window's appearance.
Glazing Upgrades
While lots of choose to retain initial crown glass for its "wavy" visual, others choose for "slimline" double glazing. These units are thin sufficient to fit into initial sash profiles, offering the thermal benefits of modern windows while keeping the thin glazing bars important for a period appearance.
