How Much Do Timber Windows Cost in Devon? A Practical Guide for Homeowners
How Much Do Timber Windows Cost in Devon? Pricing Guide (2026) - A Practical Guide for Homeowners
One of the most common questions we receive is:
“How much do timber windows cost?”
It’s a fair question—and one that many companies avoid answering online.
The reason is simple: no two properties or window projects are exactly the same. Window sizes vary, installation access differs, glazing specifications change and period properties often require additional detailing that can significantly affect cost.
That said, homeowners deserve some guidance before committing to surveys and quotations.
Below we’ve outlined some typical price ranges based on the kind of projects we regularly undertake at GS Haydon & Son Ltd in North Devon.
These are guide prices only and should not be treated as fixed quotations.We’ve included pricing for windows, doors and full replacement project
These typical installed prices are generally based on projects located within approximately 45 minutes of our workshop in North Devon. Projects further afield may involve additional travel or logistical costs.
Typical timber casement window costs
For a made-to-measure timber casement window, homeowners might typically expect:
£1,500 – £3,000 + VAT per window installed
At the lower end of this range would typically be:
- simpler opening styles
- straightforward rectangular windows
- standard glazing specifications
- easier installation access
- painted softwood windows in more sheltered locations where appropriate
At the upper end would typically include:
- more traditional detailing
- complex glazing bar layouts
- premium glazing specifications
- more involved installation requirements
- higher specification materials such as Accoya or oak where appropriate
Windows featuring shaped frames, unusual architectural details or particularly complex heritage requirements may exceed this range.
Real project example (see image below)
A recent client required:
- one heritage-style casement window
- durable hardwood construction
- pair of side-hung casements
- approximate size of 900mm x 900mm
- slim double glazing
- installation included
Total project cost: £1,700 + VAT
Traditional box sash window costs
Box sash windows are generally more complex to manufacture and install.
A typical range may be:
£2,000 – £4,500 + VAT per window installed
This reflects:
- weighted sash mechanisms
- specialist ironmongery
- heritage detailing
- glazing requirements
- access complications
Listed buildings may require additional care and consultation.
Timber entrance door costs
A bespoke timber entrance door project may typically range from:
£3,000 – £8,000 + VAT installed
At the lower end of this range may be:
- simpler painted softwood doors
- straightforward frame replacements
- standard ironmongery
- more sheltered installations
Many high-specification entrance door projects tend to fall around:
£5,500 + VAT
This may include:
- more exposed locations
- higher performance specifications
- premium ironmongery
- glazing
- more complex frame work
- higher specification materials such as Accoya or oak where suitable
Projects above this level are usually highly bespoke and often involve unusual designs or specialist requirements.
Full house replacement projects
Many homeowners ask what a complete project might cost.
As a very broad guide but this really depends on the amount of windows:
Smaller homes may begin from around:
£15,000 – £25,000+ VAT
Larger period homes can be significantly more depending on:
- number of openings
- access
- installation complexity
- design requirements
- material specification
Can I buy supply-only timber windows or doors?
Yes—sometimes clients simply want us to manufacture bespoke joinery without installation.
This may suit:
- homeowners with their own builder
- contractors managing larger renovations
- customers replacing a single door
- clients looking for a made-to-measure item only
- customers located further afield from North Devon
Supply-only pricing varies depending on design, specification and finishing requirements, but we’re always happy to discuss whether supply only or full installation is the best fit.
Why are timber windows often more expensive than online averages?
Homeowners may come across national pricing websites showing significantly lower figures.
These websites often reference:
- supply-only products
- standardised factory windows
- national averages
- simplified installations
At GS Haydon & Son Ltd, many projects involve:
- bespoke manufacturing
- heritage replication
- unusual openings
- local installation
- higher specification materials
- repair expertise where appropriate
This naturally creates a different pricing structure.
What about energy efficiency?
We can also provide whole window U-value calculations where required.
This can be useful for:
- renovation projects
- building regulation requirements
- homeowners looking to improve thermal performance
Higher performance glazing specifications can influence overall cost, and we’re happy to discuss what’s appropriate for your property rather than over-specifying unnecessarily.
Can existing timber windows be repaired instead?
Sometimes replacement isn’t necessary.
We regularly advise homeowners when repair may be more sensible than full replacement.
This could include:
- replacing failed glass units
- repairing localised timber decay
- easing windows
- draught proofing
- replacing hardware
- repainting and maintenance work
In some situations, repair can be significantly more cost effective.

When we may not be the right fit
We may not be the best option if:
- you’re looking for mass-produced windows at the lowest possible price
- you need nationwide installation
- you’re comparing bespoke joinery with off-the-shelf alternatives
We tend to suit homeowners looking for long-term value, repairability and traditional craftsmanship.
What affects the final cost?
The biggest variables tend to be:
- property access
- scaffolding
- glazing specification
- bespoke design requirements
- listed building constraints
- decorating requirements
- installation complexity
Our advice
We believe clearer pricing helps homeowners budget realistically and avoids wasting time pricing projects that are unlikely to be the right fit.
If you’re comparing timber windows, try to compare like-for-like.
The cheapest online figure may not include:
- installation
- decorating
- certification through CERTASS
- bespoke detailing
- aftercare
And equally, not every property needs full replacement.
If you’re unsure whether repair or replacement is the right route, we’re always happy to offer honest advice.
