Conventional single glazing and the intrinsic gaps required for sash windows to move smoothly lead to considerable heat loss. This often causes a cold living environment and high energy expenses.
3. Paint Seizure and Rattle
Years of over-painting can cause windows being "painted shut." Conversely, wood shrinkage over a century can cause sashes to fit loosely in their frames, causing irritating rattles during windy weather.

Timber Repair and Resin Splicing
Rather than replacing a whole frame, experts use "splice repairs." Decayed sections are removed and replaced with matching experienced lumber. High-performance epoxy resins are often used to combine weakened wood and produce a seamless, weather-proof bond in between old and brand-new wood.
Draught-Proofing Installation

| Thermal Efficiency | Significantly improved through seals. | Outstanding (Modern requirements). | Outstanding for acoustic/thermal. |
| Lifespan | 20-- 40 years with maintenance. | 30-- 50 years. | 10-- 20 years. |
| Preparation Permission | Typically not needed (Maintenance). | Frequently needed in Heritage areas. | Periodically needed for listed. |
| Cost | Moderate. | High. | Low to Moderate. |
The Benefits of Professional Renovation
