Understanding the Need for Specialist Sash Window Services
Unlike contemporary uPVC casement windows, traditional sash windows are complex mechanical systems including wheels, weights, and cables hidden within the “box” frame. House owners often face a predicament: change the initial windows with modern alternatives or buy remediation.
From a heritage point of view, protecting original timber is often chosen. Additionally, expert restoration can often bring an old window's thermal and acoustic efficiency up to modern-day standards without compromising its visual stability.
Common Issues Affecting Sash Windows
Before looking for professional services, it is handy to identify the common disorders that impact these windows.
- Rotting Timber: Moisture typically accumulates on the sills or at the bottom of the lower sash, leading to fungal growth and wood decay.
- Snapped Cords: Over time, the sash cables (normally made from waxed cotton) can fray and break, avoiding the window from remaining open.
- Stuck Windows: Layers of old paint typically seal the sashes shut, or the timber may have inflamed due to moisture.
- Rattling and Draughts: Gaps between the sashes and the frame permit cold air to go into and heat to escape, often leading to frustrating rattling during windy weather.
Glass Damage: Older glass can be thin and delicate, causing fractures or security concerns.
