From a heritage viewpoint, preserving original timber is almost constantly preferred. In addition, expert repair can typically bring an old window’s thermal and acoustic efficiency up to modern standards without sacrificing its visual integrity.

Common Issues Affecting Sash Windows

Before looking for expert services, it is handy to recognize the typical disorders that impact these windows.

• Stuck Windows: Layers of old paint often seal the sashes shut, or the timber may have inflamed due to dampness.
• Rattling and Draughts: Gaps in between the sashes and the frame allow cold air to enter and heat to get away, typically resulting in bothersome rattling throughout windy weather.
