Read MoreReddish Joinery has been producing high-quality window joinery since 1967, so we understand the importance of retaining the period and character features of traditional windows. Getting these details right is important not only for the kerb appeal of the property, but particularly for maintaining the internal aesthetics of a period home.

The vertical sliding operation of sash windows is not only aesthetically pleasing, but incredibly practical too, requiring no swing space whilst letting in plenty of fresh air. Modern materials mean that wooden sash windows remain as in-demand today as they were during the Industrial Revolution, when they were found across the nation.
Thanks to these good looks and strong performance, it’s only natural to ask yourself ‘how much do new wooden sash windows cost?’
As a useful guide, we would suggest allowing around £3,500 to £5,000 per window, including installation, for a quality timber sash window. Larger windows, specialist glazing and bespoke detailing can push the price higher.
There is no universal figure, however, because costs vary on several factors such as the wood used, the glazing and your location.
Therefore, the most accurate way to understand your sash window replacement costs, by far, is to request a no-obligation quote from a reputable supplier. At Reddish Joinery, we consider the size of your openings, location, finish, type of glazing, access and the character of your property before providing an exact quote, which can be obtained by email, over the phone or simply by filling out our form.
Wooden sash windows: the key cost drivers
Several factors influence the final sash window cost:
| Cost factor | What it means for your budget |
| Timber grade | Premium timber such as Accoya can cost slightly more than standard softwood, but makes up for it in quality |
| Glazing | Double glazing and specialist glass can increase the price |
| Ironmongery | Traditional handles, locks and fittings vary in cost |
| Window size | Larger windows require more materials and manufacturing time |
| Location | Some areas of Cheshire, Lancashire and Greater Manchester can sit above national averages |
| Property condition | Older properties may require additional preparation |
| Access | Difficult access can increase installation costs |
| Detailing | Bespoke mouldings and conservation requirements can add extra cost |
| Job type | New sashes in an existing frame can cost differently from a full replacement |
Timber and glazing
There are several different forms of timber, so it’s important to choose the right one. At Reddish Joinery, we specialise in Accoya timber sash windows.
Accoya is a modified softwood produced using acetylation. This makes it highly resistant to swelling, shrinking, warping, rot and insect damage, which makes it just as durable as the vast majority of hardwoods. It is particularly well suited to sash windows, where this stability helps ensure smooth operation.
Glazing also affects sash window prices. Modern double glazing is designed to reduce heat transfer compared with old single-glazed windows, helping improve energy efficiency. Acoustic glass is available where reducing outside noise is important.
The design of the window matters, too. Traditional sash windows rely on carefully balanced sashes and sash cords, so replacing an old window involves considerably more than simply fitting glass into a frame.
Why we specify Accoya windows
We choose Accoya because it brings together the appearance of traditional joinery with impressive modern performance.
The timber is sustainably sourced and fully recyclable. It is highly resistant to rot, decay and insect attack, while its stability helps minimise swelling and warping.
For homeowners considering new windows, Accoya offers:
- Excellent durability
- Low maintenance requirements
- Strong resistance to rot and decay
- Excellent thermal insulation
- Smooth sash operation
- Authentic period property styling
- Sustainably sourced and recyclable timber
Our Accoya wood products are guaranteed for 50 years. We can also manufacture timber sash windows to match existing designs, making them particularly suitable for period homes.
Wooden sash window full cost comparison
You should expect to pay around £3,500 to around £5,000 for a proper wooden sash window.
This can cover supply, manufacture and installation with premium Accoya frames, although the full cost of timber windows depends on the individual project.
The cheapest option is not always the most appropriate. A higher-quality timber and carefully selected glazing may have a higher upfront price, but durability, appearance and performance are important considerations for a long-term investment, which is why we always recommend Accoya.
It is also worth comparing full replacement with old sash window restoration. Where an original frame remains suitable, replacing the sashes may require less work than replacing the entire window.
What are the benefits of new wooden sash windows?
New wooden sash windows can be a worthwhile choice for homeowners looking to combine period character with modern performance.
- Period appeal: Timber sash windows complement many historic and traditional properties.
- Energy efficiency: Modern glazing can reduce heat loss and may help reduce energy bills.
- Conservation suitability: New timber is often appropriate for a listed building and can be well suited to homes in a conservation area, subject to the relevant requirements.
- Durability: Accoya provides excellent resistance to rot, decay and movement.
- Bespoke design: We can manufacture windows to match existing architectural details.
- Low maintenance: Accoya requires less upkeep than many traditional timbers.
- Choice: For homeowners comparing materials, we also offer uPVC sash windows as a low-maintenance alternative.
A spacious alternative: Accoya bay windows
Bay windows typically come in at a higher price point, with a traditional three-section bay replacement window with existing brick pillars usually costing around £13,000-£15,000. Unlike a single sash window, a traditional bay involves three individual Accoya window sections, each carefully made to replicate the proportions and detailing of the original windows. The price also includes the internal timber and decorative finishing needed to ensure the completed bay looks right from inside as well as out, and closely matches the character of the existing property.
For period properties in particular, this level of detail is important. Replacing a traditional bay requires careful attention to the existing architecture, joinery details and internal finishes to create a result that feels sympathetic to the original building. This additional craftsmanship is why a traditional three-section bay costs more than an individual sash window.
