Maintaining sash windows authenticity: A Like-to-Like Repair
Ensuring any restoration work follows a like-to-like process gives you the best chance of retaining your sash window’s authenticity.
This means using the same materials in the same way as the original fitting. Choosing the wrong type of timber can lead to structural issues and irreparable damage to sash windows, as well as leaving a disjointed look that compromises the authentic feel of the architecture. For this reason, you want to consult with a reputable company that specializes in selling timber to ensure you have the right type for your project.
Matching the style of your property’s window
There are many different types of sash windows in England, including Venetian, Traditional, Hidden Spring, Georgian, and Half-Georgian sash windows.
Each style has distinctive architectural features that need consideration to maintain the overall authenticity of the window. Repairs need to be done to match the style of your property’s window. If you’re unsure about how to recognize which style your window is or how to maintain that style, contacting a professional is the best option.
Don’t replace the existing sashes with a new one which has a different glazing configuration
Make sure to understand the glazing configuration of your current sash windows, and if you ever replace the panes, make sure it’s in keeping with that configuration. Glazing refers to the number of panes within a window; your windows can have single, double, or triple glazing.
The window structure around the panes will have been originally constructed with a specific glazing configuration in mind.
By changing the glazing configuration and not the timber around it, you’ll be left with a mismatch between the two, which compromises the authenticity of the window’s appearance.
You could replace both the glazing and the timber around it to match the new configuration, but this would require extensive work akin to replacing the entire window. A full replacement also runs the risk of losing the original window’s architectural authenticity.
