How Much Do Timber Casement Windows Cost in Devon? A Practical Guide for Homeowners (2026)

How Much Do Timber Casement Windows Cost in Devon? A Practical Guide for Homeowners (2026)

One of the most common questions we are asked is:

"How much do timber casement windows cost?"

Unfortunately, there is no single answer.

Like most bespoke joinery, the cost depends on factors such as size, timber choice, glazing specification, detailing and installation requirements. A small cottage window will naturally cost less than a large feature window in a listed building.

However, we believe homeowners should have a realistic idea of likely costs before arranging surveys and quotations.

The figures below are intended as a practical guide based on the type of bespoke timber windows we manufacture and install throughout Devon.

What Is a Timber Casement Window?

A casement window is the most common style of opening window found in British homes.

The opening section is hung on hinges and opens either side-hung or top-hung. Casement windows can be manufactured in many different configurations, from simple single-opening windows through to larger multi-light designs with glazing bars and traditional detailing.

They are commonly found in cottages, farmhouses, period properties, village homes and more modern houses throughout Devon.

Typical Timber Casement Window Costs

As a broad guide, homeowners can expect the following:

Window Type

Typical Installed Cost

Small timber casement window

From £1,500 + VAT

Average timber casement window

£1,700 – £2,500 + VAT

Larger or more detailed windows

£2,500 – £3,500 + VAT

Complex heritage or listed building windows

£3,500+ + VAT

These figures are intended as guidance only but should provide a realistic indication of the investment required for high-quality bespoke timber windows.

A Real Example

As an example, a recently manufactured and installed hardwood casement window measuring approximately 900mm x 900mm, complete with traditional detailing and double glazing, was approximately £1,700 + VAT.

This is not intended as a fixed price but demonstrates the sort of costs typically involved for a bespoke timber window manufactured to suit an individual property.

Why Do Timber Window Costs Vary?

There are several factors that influence the final cost.

Size

Larger windows require more timber, larger glass units and additional manufacturing time.

Timber Choice

We commonly manufacture our casement windows windows from durable hardwoods, Oak and Accoya.

Each material has different characteristics, appearance and cost implications. If you would like more information on timber we use read our guide on the best wood for windows here

Glazing Specification

The choice between single glazing, standard double glazing, slim heritage double glazing and in extreme situations vacuum glazing can significantly affect costs.

Design Complexity

Simple windows are generally quicker to manufacture than windows incorporating glazing bars, shaped heads, traditional mouldings or heritage detailing.

Installation Requirements

Access, scaffolding requirements, internal finishes and the condition of the existing openings can all influence installation costs.

Are Timber Windows More Expensive Than uPVC?

In most cases, yes.

Bespoke timber windows typically cost more than mass-produced uPVC alternatives.

However, many homeowners choose timber because of its appearance, repairability and suitability for period properties.

Timber windows can often be repaired and maintained for many decades, whereas replacement is often the only option when many modern alternatives reach the end of their service life.

For listed buildings and traditional properties, timber is often the most appropriate choice aesthetically and, in some cases, a planning requirement.

Can Existing Timber Windows Be Repaired Instead?

Sometimes.

Not every window needs replacing.

In our experience, many older timber windows can be repaired, overhauled and upgraded at significantly lower cost than full replacement.

Where repair is a sensible option, we will generally recommend it.

How Long Does It Take?

Bespoke timber window projects are manufactured to order.

Lead times vary throughout the year but a typical project may take between 8 and 12 weeks from initial survey through to installation.

More complex projects or periods of high demand may extend these timescales. If you'd like to know more about lead times feel free to read our guide here.

Is It Worth Investing in Timber Windows?

For many homeowners, the answer is yes.

Well-designed timber windows can enhance the appearance of a property, improve comfort and preserve the character of older buildings.

They are particularly popular in Devon's cottages, farmhouses, village homes and listed properties where traditional appearance is often an important consideration.
