Frequently Asked Questions About Sash Windows
For expert assistance, explore a comprehensive guide to how sash windows work.
If you own a period property in Edinburgh with sash windows, you probably have questions about their care, repair and modernisation. This comprehensive FAQ covers the most common questions Edinburgh homeowners ask about their sash and case windows.
General Questions
What are sash windows?
Sash windows, also known as sash and case windows in Scotland, consist of two vertically sliding panels (sashes) held within a timber frame. They are operated by a system of cords, pulleys and concealed counterbalance weights.
Why are they called sash and case windows in Scotland?
In Scotland, the frame is traditionally called the “case” and the sliding panels are the “sashes” — hence sash and case. This distinguishes them from the English box sash window design.
Are sash windows suitable for Edinburgh’s climate?
Yes, when properly maintained and draught-proofed. Timber sash windows perform well in Edinburgh’s climate if kept painted and sealed.
Repair and Maintenance
How long do sash windows last?
With proper maintenance, original Victorian and Georgian sash windows can last 150 years or more. Many Edinburgh tenements still have their original windows.
How much does sash window repair cost in Edinburgh?
Costs vary by repair type — cord replacement from £80 per window, draught proofing from £150 per window, and full restoration from £350 per window. Call 0131 381 8222 for a free quotation.
Do sash windows need to be replaced eventually?
Not necessarily. Most sash windows can be repaired and restored indefinitely if they receive regular maintenance. Replacement is only needed when rot is too extensive for economical repair.
Energy Efficiency
Can sash windows be energy efficient?
Absolutely. With professional draught proofing, secondary glazing or slimline double glazing, sash windows can achieve excellent thermal performance.
Will draught proofing affect window operation?
No — professional draught proofing is designed to allow smooth operation while sealing the gaps that cause draughts.
Is double glazing possible for sash windows?
Yes — slimline double glazed units can be fitted into existing sash frames without altering their traditional appearance.
Planning and Conservation
Do I need planning permission for sash window repairs?
Like-for-like repairs generally do not require permission. However, replacing windows or changing their appearance in a Conservation Area may require consent.
Can I replace sash windows with UPVC in a Conservation Area?
This is rarely permitted in Edinburgh’s Conservation Areas. Like-for-like timber replacement is usually required.
Are replacement UPVC sash windows a good option?
For period properties, we recommend timber over UPVC. Timber offers better authenticity, longevity and property value retention.
