What Are Sash Windows?
Sash windows are recognised by their distinctive sliding design. Rather than opening outwards like a traditional casement window, one or more sections of the window move vertically within the frame.
Their balanced proportions and traditional appearance have made sash windows a familiar feature on many period and character properties. Modern sash window systems can retain this classic style while incorporating contemporary frames, glazing and hardware.
The vertical sliding design also allows homeowners to adjust the size of the opening depending on how much ventilation is required.

The performance of a new sash window
depends on accurate measurements and professional installation. Our window fitting service includes precise measurement and fitting to help ensure your new windows operate and seal correctly.
Classic Appearance for Traditional & Modern Homes
One of the main reasons homeowners choose sash windows is their distinctive appearance.
Their vertical proportions can complement older homes where retaining architectural character is important, but modern sash windows can also work effectively on newer properties where homeowners prefer a more traditional window style.
Our made-to-measure sliding sash windows in Deeside, Chester and the wider North West are designed to allow the dimensions and glazing arrangement to be adapted to the opening, helping the finished installation sit naturally within the property.
This makes sash windows particularly suitable for homeowners who want to improve the performance of their glazing without losing the visual character associated with a traditional sliding window.
Energy-Efficient Sash Windows
Traditional appearance does not mean homeowners have to accept outdated glazing performance.
Modern sash windows can be fitted with energy-efficient glass designed to improve insulation compared with older, failed or inefficient window units.
Our A+ rated glazing options can help to:
-
Reduce unnecessary heat loss
-
Improve indoor comfort during colder weather
-
Reduce draughts associated with ageing windows
-
Improve the performance of old glazing
-
Provide modern double-glazing performance
-
Reduce condensation associated with failed sealed units

Replacing Existing Sash Windows
Ageing sash windows can become difficult to operate or may no longer provide the insulation and comfort expected from modern glazing.
Signs that replacement may be worth considering include:
-
Draughts around the window
-
Difficult or stiff operation
-
Damaged or deteriorated frames
-
Failed double glazing
-
Misting between panes
-
Noticeable heat loss
-
Windows that no longer close or seal correctly
Our replacement window service includes professional assessment, accurate measurement and made-to-measure installation.
However, misted or failed glazing does not always mean the entire window needs replacing.
Where the frame and operating system remain in good condition, our glass replacement service may allow the failed sealed unit to be replaced while retaining the existing window.
If you are unsure which option is appropriate, read our guide to glass-only replacement vs full window replacement.
What to Expect from Our Sash Window Installation
Every project begins with an assessment of your existing windows and accurate measurements of the relevant openings.
We can then discuss the sash window design, frame and glazing requirements before your made-to-measure units are prepared.
The typical process includes:
-
Assessing your existing windows
-
Taking accurate measurements
-
Discussing the required sash window configuration
-
Selecting suitable glazing
-
Preparing made-to-measure window units
-
Professionally installing and sealing the windows
-
Checking operation, fit and final finish
Our aim is to provide a properly fitted sash window that operates smoothly and delivers the performance expected from modern replacement glazing.
