Frequently Asked Questions
How long do sash and case windows last?
Properly maintained timber sash and case windows can last 100+ years. Original Victorian windows are still in service across Edinburgh. The key is regular painting and draught-proofing to prevent moisture ingress.
Can I get double glazing in a sash and case window?
Yes. We offer standard double-glazed units, slim-line heritage units, and Fineo vacuum glass — all fitted into traditional timber sash frames. For most non-listed properties, standard double glazing is the best option.
Do I need planning permission for new sash windows?
For most properties, replacing like-for-like does not require planning permission. If your property is listed or in a conservation area, you will need to check with your local authority. We can advise on what is and isn't permitted for your specific property.
How long does it take to get new sash windows?
Supply-only orders typically take 8–10 weeks from order to delivery. Supply and fit projects take longer depending on programme. We'll give you a firm lead time at the point of quotation.
Do you supply sash windows to the trade?
Yes. We are a specialist trade supplier of sash and case windows to joiners, developers, and main contractors across Scotland and the UK. Contact our trade team for pricing and lead times.
What timber do you use for sash windows?
We use slow-grown European softwood as standard, and Accoya® for clients requiring maximum durability — particularly for coastal, exposed, or heritage properties. Accoya carries a 50-year above-ground guarantee.
Are your sash windows suitable for listed buildings?
Yes. We have extensive experience with Category A and B listed properties across Scotland. We can specify Fineo vacuum glass or slim-line heritage units where original profiles must be maintained. We work with conservation officers to ensure compliance.
