Wood Sash Windows
Bespoke timber sash windows for period, heritage and premium homes
H&C Joinery designs, manufactures and installs bespoke wood sash windows for period homes, heritage buildings, listed properties and premium residential projects.
Every sash window is made to measure in our workshop, with the profiles, glazing bars, mouldings, timber, glazing and finish chosen around your property. Whether you need new timber sash windows to match the originals, replacement sash windows for a renovation, or a full set of handmade windows for a high-end refurbishment, we can manufacture sash windows that look right and perform properly.
Our wood sash windows can include traditional weights and pulleys, slim glazing bar details, modern draught proofing, suitable glazing options and a factory-applied paint or stain finish.
What are wood sash windows?
Wood sash windows are traditional timber windows with one or more sliding panels, known as sashes. They are commonly found in Georgian, Victorian and Edwardian homes, as well as many listed buildings and conservation properties.
In most traditional sash windows, the moving sashes are balanced by weights hidden inside the box frame. This allows the window to slide open and closed smoothly while keeping the external appearance elegant and simple.
The main benefit of timber sash windows is that they can be made to match the character of the building. The thickness of the glazing bars, the moulding profile, the meeting rail, the horns, the sill and the overall proportions all affect whether the finished window looks right.
For period properties, those details matter.
Why choose bespoke timber sash windows?
Standard sash windows are made around product ranges. Bespoke timber sash windows are made around your property.
That gives you far more control over the appearance, proportions and detail of the finished windows. This is especially important where original windows need to be replicated, where a property is listed, or where the building has distinctive mouldings and glazing bar layouts.
Bespoke wood sash windows are especially useful when you need:
- Replacement sash windows for a period home
- New sash windows to match original joinery
- Narrow glazing bars and traditional mouldings
- Sash windows for listed or conservation-sensitive buildings
- Handmade windows for a premium refurbishment
- Better draught proofing and comfort
- Glazing options that suit the property
- A factory-painted finish matched to the building
Replacement wood sash windows
Replacement sash windows need to be handled carefully.
A poor replacement can damage the appearance of the whole property, especially if the glazing bars are too thick, the sections are too flat, or the proportions are wrong. This is why replacing sash windows is not just a product decision. It is a design and joinery decision.
H&C can manufacture replacement timber sash windows to closely match the original windows, including box frame proportions, sash profiles, glazing bar layouts, horn details, meeting rail details, sill sections, moulding profiles, paint colours and ironmongery style.
This allows the new windows to improve comfort and operation while preserving the character of the property.
Sash windows for listed buildings and conservation properties
Listed buildings and conservation properties often require a more careful approach.
In many cases, replacement windows need to match the original appearance very closely. That may include the same opening style, moulding shape, glazing layout, timber section and paint finish. In some cases, repair or restoration may be more appropriate than full replacement.
H&C can advise on whether new timber sash windows, sash window restoration or secondary glazing is likely to be the best route.
For listed and heritage projects, options may include like-for-like timber sash window replacement, slimline heritage glazing where suitable, single glazing where required by the specification, traditional weights and pulleys, matched mouldings and glazing bars, linseed oil paint or conservation-sensitive finishes where specified, and coordination with architects, contractors or conservation consultants.

Glazing options for timber sash windows
The right glazing depends on the age of the property, the depth of the sash, the required appearance and any planning or conservation restrictions.
For some heritage projects, single glazing may still be required. For others, slimline heritage glazing or vacuum glazing may offer a better balance between appearance and performance. In less sensitive settings, double glazing may be possible.
H&C can advise on suitable glazing options for the property and project requirements. Common options include traditional single glazing, slimline heritage double glazing, vacuum glazing, standard double glazing where appropriate, acoustic glass, toughened or laminated glass where required, and decorative or obscured glass.
The priority is to avoid forcing the wrong glazing into the wrong window. On period buildings, thick glazing units can damage the appearance of slender sash profiles if they are not specified carefully.
“With sash windows, the fine details make the difference. We look at the whole window, from proportions and mouldings to glazing, draught proofing and finish, so the result sits properly with the building.”
Draught proofing, comfort and operation
Old sash windows often suffer from rattles, draughts, sticking sashes and heat loss. New timber sash windows can address these issues while keeping the traditional style of the property.
Depending on the design and specification, H&C sash windows can include modern draught proofing, smoother operation, suitable weather seals and improved glazing performance.
Performance improvements can include reduced draughts, smoother opening and closing, improved thermal comfort, better acoustic performance, more secure fasteners, easier maintenance and better paint finish and timber protection.
For properties where the existing sash windows have historic value, restoration or secondary glazing may be the better choice. For windows that are beyond sensible repair, new bespoke timber sash windows can provide a more complete long-term solution.
Timber, finish and traditional details that matter
Good sash windows depend on good timber, careful detailing and the right finish.
H&C can manufacture timber sash windows using Accoya, Sapele or other selected hardwoods and modified timbers depending on the property, exposure and finish required. Accoya is often recommended for painted external joinery because of its stability and durability.
Windows can also be factory finished before installation. This helps create a consistent coating in controlled workshop conditions and gives the timber protection before it reaches site.
On sash windows, the small details are everything. H&C can manufacture sash windows around the features that define the building, including Georgian six-over-six glazing patterns, Victorian two-over-two arrangements, Edwardian sash window styles, cottage sash windows, narrow glazing bars, lamb’s tongue mouldings, ovolo mouldings, sash horns, deep sills and traditional ironmongery.
Designed around the building, not a standard product range
Every sash window is made to measure, with timber, profiles, glazing bars, mouldings, glazing and finish selected around the property. This gives H&C the flexibility to match original details while improving comfort, operation and durability where appropriate.
For period homes and heritage buildings, the aim is to preserve the fine proportions that make the windows look right, rather than making them bulky or generic.

Bespoke timber sash windows made for your property
Every sash window project starts with the building. H&C will review the existing windows, property style, opening sizes, planning constraints and desired performance before advising on the best route.
Where replacement is right, each sash window is designed and manufactured around the original details or the agreed specification.
New sash windows, restoration or secondary glazing?
Not every sash window project needs full replacement. If the existing windows are structurally sound and have real heritage value, restoration may be better. If the property is listed or restrictions make replacement difficult, secondary glazing may provide improved comfort without changing the external appearance.
H&C can help assess the right route for you.

How the process works
1. Initial conversation
We discuss your property, project requirements, existing joinery and what you want to achieve. Photographs, drawings, approximate sizes and information about listed or conservation status are useful starting points.
2. Survey and specification
Where appropriate, we survey the property, assess the existing joinery and review measurements, condition, access, performance requirements and surrounding architectural details.
3. Design and quotation
We explain the most suitable options and prepare a clear specification and quotation. Depending on the project, this may include drawings, materials, profiles, glazing, finishes, ironmongery and installation requirements.
4. Manufacture and finishing
The agreed joinery is manufactured, repaired or restored by H&C’s workshop team. Materials, profiles, construction details and finishes are completed to the approved specification.
5. Delivery and installation
Depending on the project scope and location, the completed joinery is supplied or installed. Final checks and adjustments are completed so the finished work looks right and performs properly.
Project example: heritage shopfronts and hardwood sash windows
H&C manufactured and installed three bespoke heritage shopfronts on Coatsworth Road, Gateshead, as part of a major regeneration project commissioned on behalf of Gateshead Council.
Alongside the shopfronts, H&C also supplied 25 large traditional hardwood sliding sash windows and hardwood doors, working through main contractor Wentworth Construction and alongside architects and conservation consultants.

FAQs about wood sash windows
Are wood sash windows suitable for listed buildings?
Yes, but the specification needs to be handled carefully. Listed buildings often require replacement sash windows to closely match the originals, including proportions, mouldings, glazing bars and materials. In some cases, restoration or secondary glazing may be more appropriate than replacement.
Can timber sash windows be double glazed?
Yes, in many situations. Timber sash windows can be made with slimline heritage glazing, vacuum glazing or standard double glazing depending on the property, sash design and any planning or conservation requirements.
Can new sash windows match the original windows?
Yes. Bespoke timber sash windows can be made to closely match original windows, including glazing bar layouts, moulding profiles, horn details, sill sections and paint colours.
Should I replace or restore my sash windows?
If the existing windows are structurally sound and have original heritage value, restoration may be the better option. If they are badly decayed, poorly altered or beyond practical repair, new bespoke timber sash windows may be more suitable.
What is the difference between sash windows and casement windows?
Sash windows usually slide vertically within a frame, while casement windows are hinged and open outwards or inwards. Sash windows are especially common on Georgian, Victorian and Edwardian homes.
What timber is best for sash windows?
Accoya is often recommended for painted external sash windows because of its stability and durability. Sapele and other selected hardwoods or modified timbers may also be suitable depending on the project and finish.
Can sash windows reduce draughts?
Yes. New timber sash windows can include draught proofing, weather seals and suitable glazing to improve comfort. Existing sash windows can also often be draught proofed as part of restoration.
Do timber sash windows need much maintenance?
They need sensible routine care. This usually includes keeping the finish clean, checking for coating damage, maintaining moving parts and touching up exposed areas before moisture can enter the timber.
