    Should you repair/refurbish your sash windows or simply replace them?

    We think there a few good reasons to refurbish sash windows rather than replace them. 

    1. Historical and architectural value: Sash windows are often installed in older and historical buildings, contributing to their charm and character.  In Richmond, we’re lucky to have many heritage and period properties. Understandably, residents are keen to maximise the historical and heritage value of their homes. Refurbishing your windows helps preserve the original architectural features and maintains the authenticity of the property. By refurbishing sash windows, you can retain the historical value of your house, while enhancing its overall aesthetic appeal.

    2. Cost-effectiveness: Refurbishing sash windows can be a cost-effective alternative to complete window replacement. Replacing windows entirely can be expensive, especially when dealing with multiple windows. Refurbishing sash windows involves repairing and restoring the existing frames, replacing damaged components, and improving their functionality. This approach can save a significant amount of money compared to installing brand new windows.

    3. Energy efficiency and insulation: Older sash windows may have gaps, cracks, or inefficient glazing, which can result in drafts and heat loss. By refurbishing these windows, you can address these issues and improve energy efficiency. Upgrading from single to double glazing can significantly enhance insulation, reduce heat transfer, and contribute to lower energy bills. Additionally, sealing any gaps or cracks and ensuring proper weather-stripping can further improve insulation, making the space more comfortable and reducing energy waste.
