Common questions about sliding sash windows
Considering sash windows for a period or tenement home? Here are quick answers about warmth, character, cleaning and installation across Scotland.
What is a sliding sash window?
A sliding sash window – or sash and case – has panes that slide vertically within the frame. It’s the traditional style of Victorian, Georgian and tenement homes across Scotland.
Are modern sash windows warmer than the originals?
Much warmer. Ours are A-rated, double glazed and draught-proofed, so you keep the classic look without the cold, rattles and draughts of an original single-glazed sash.
Will they suit my period or tenement home?
Yes. Run-through sash horns, astragal or Georgian bars and heritage colours preserve the traditional look. In conservation areas the rules can vary, so we’ll advise on what’s suitable for your property at your free survey.
Do your sash windows tilt in for cleaning?
Yes. Both sashes tilt inward so you can clean the outside of the glass from inside – a real advantage in upper-floor flats and tenements.
Do modern sash windows still use cords and weights?
No. Ours use modern spiral balances that glide smoothly up and down, with nothing to wear out or snap like the old cord-and-weight system.
Are uPVC sash windows secure?
Yes. Multi-point locking makes them far more secure than the simple catches on original sash windows.
What colours and bar options are available?
Traditional whites, heritage greys and realistic woodgrain finishes, with Georgian bar and sash-horn options to match the character of your home.
How much do sliding sash windows cost?
It depends on the size, glazing and detailing you choose. The best way to get an accurate price is a free, no-obligation survey – we’ll give you a fixed written quote with no hidden extras.
Do you fit sash windows across Scotland?
Yes. We supply and fit sliding sash windows across Scotland, including the tenements and period homes of Glasgow and Edinburgh, plus Aberdeen, Dundee, the Highlands and everywhere between.
Do you remove my old windows?
Yes. We remove your old frames, fit the new ones and leave your home clean and tidy.
