Overview
Mock sash windows combine the timeless appearance of traditional sliding sash windows with the practicality of a modern casement design. Carefully engineered to replicate the proportions and detailing of authentic sash windows, they preserve the character of period properties while delivering the performance, security and energy efficiency expected of contemporary timber joinery.
Unlike true sliding sash windows, mock sash windows operate on side-hung or top-hung hinges while maintaining the appearance of a classic sash window. Traditional features such as sash horns, meeting rails and glazing bars make them an excellent choice for homeowners seeking heritage styling with the simplicity and reliability of a casement window.
At James Wilding Joinery, every bespoke timber mock sash window is handcrafted to order in our workshop in Rylstone, near Skipton. Whether for a Victorian townhouse, Georgian home, country cottage, conservation project or contemporary property inspired by traditional architecture, every window is tailored to complement the character of your home.
Why Choose Timber?
Timber is an exceptional material for bespoke mock sash windows, combining natural character, structural strength and considerable design flexibility. Its authentic appearance makes it particularly well suited to period properties, heritage architecture and contemporary homes inspired by traditional design.
The versatility of timber allows glazing bars, sash horns, mouldings and carefully proportioned profiles to be manufactured with precision. This is particularly important with mock sash windows, where carefully considered proportions and detailing help recreate the appearance of traditional sliding sash windows.
Timber can also be repaired, refinished and maintained throughout its serviceable life. Responsibly sourced timber is a renewable building material, making it a considered choice for homeowners seeking high-quality bespoke windows.
WHy Choose Accoya?
Accoya® is a high-performance modified timber particularly well suited to bespoke external joinery, including mock sash windows. Its acetylation process significantly improves dimensional stability and durability, helping the timber resist swelling, shrinking and movement when exposed to changing weather conditions.
This dimensional stability is particularly valuable for precision-made windows, helping carefully manufactured components, seals and opening sections maintain their intended fit and operation. Accoya® also offers excellent resistance to rot, decay and insect attack.
Its stability provides an excellent substrate for professional factory-applied finishes, while its workability allows traditional glazing bars, sash horns, mouldings and bespoke timber profiles to be manufactured with precision.
For homeowners looking for high-performance bespoke timber mock sash windows, Accoya® offers an excellent combination of dimensional stability, durability and design versatility.
Why Choose Mock Sash Windows?
Mock sash windows combine the timeless appearance of traditional sliding sash windows with the simplicity and reliability of modern casement operation. Carefully designed to replicate classic sash proportions, glazing bars and authentic sash horns, they are an ideal choice for homeowners seeking period character without the complexity of traditional sliding mechanisms.
Unlike vertically sliding sash windows, mock sash windows are side or top hung, providing excellent weather sealing, enhanced security and straightforward everyday operation. Their versatile design makes them particularly well suited to period homes, conservation projects, barn conversions and contemporary homes inspired by traditional architecture.
Combining authentic detailing with modern glazing, precision engineering and exceptional thermal performance, bespoke timber mock sash windows bring together traditional character and modern practicality.

Architectural Window Hardware & Ironmongery
Beautifully crafted mock sash windows deserve carefully selected window furniture that complements both their appearance and everyday performance. The right architectural hardware enhances the character of your windows while providing smooth operation and dependable security.
Every bespoke timber mock sash window is individually specified using premium-quality hardware from trusted manufacturers including From the Anvil, Croft Architectural Hardware and Coastal Group.

Bespoke Glazing
Glazing plays an important role in the appearance and performance of bespoke timber mock sash windows. We offer a comprehensive range of glazing options, allowing the specification to be tailored to the property, window design and requirements of the project.
Our glazing options include:
- High-Performance Double Glazing
- Heritage Double Glazing
- Toughened Safety Glass
- Laminated Security Glass
- Acoustic Glazing
- Decorative Glass
- Obscure Privacy Glass
- Traditional Leaded Glass
- Bespoke Stained Glass
For period properties, conservation areas and heritage projects, Heritage Double Glazing can be incorporated where traditional proportions need to be considered alongside improved thermal performance. Where original leaded or stained glass survives, we can carefully incorporate existing panels where suitable or create bespoke replacements that complement the character of the property.
High-performance glazing can help improve thermal efficiency and reduce heat loss, while acoustic, safety, security and solar control glazing can be specified according to the individual requirements of the project.
Every glazing specification is individually considered to balance natural light, thermal efficiency, security and appearance while preserving the carefully considered proportions of the mock sash window.
Factory Finishing
A beautifully crafted timber mock sash window deserves an equally exceptional finish.
Every window is professionally prepared and factory finished in our dedicated spray facility using advanced Teknos microporous coating systems. These specialist finishes protect against moisture, UV exposure and the changing British climate while allowing the timber to breathe naturally.
We can colour-match most paint specifications, including Farrow & Ball, Little Greene, Dulux and the RAL Colour Collection. We also offer a carefully selected range of premium stains to enhance the natural beauty of Accoya®, European Oak and Sapele.
Every mock sash window undergoes a thorough quality inspection before leaving our workshop in Rylstone, near Skipton, helping to ensure the finish, operation and craftsmanship meet our standards.

Frequently Asked Questions
What are mock sash windows?
Mock sash windows are hinged casement windows that are carefully designed to replicate the appearance of traditional vertically sliding sash windows. Decorative features such as sash horns, meeting rails and glazing bars create an authentic heritage appearance while offering the practical benefits of modern casement operation.
What is the difference between mock sash windows and sliding sash windows?
The primary difference is how they open. Mock sash windows operate on side-hung or top-hung hinges like a casement window, whereas traditional sliding sash windows move vertically within the frame using sash balances or cords and weights. Mock sash windows provide the appearance of sash windows while offering simpler operation and maintenance.
Are mock sash windows suitable for period properties?
Yes. Their authentic appearance makes them an excellent choice for many period homes, cottages and sympathetic renovations. We carefully design each window to complement the architectural style of your property while incorporating modern performance and security features.
Can mock sash windows be installed in conservation areas?
In many cases, yes. Requirements vary depending on the local planning authority and the individual property. We regularly work with homeowners, architects and conservation professionals to produce bespoke timber windows that satisfy both aesthetic and planning requirements.
Which timbers do you offer?
We manufacture bespoke mock sash windows using carefully selected Accoya®, European Oak and Sapele. The most appropriate timber will depend on the property, design, desired appearance, finish and exposure to weather, and our experienced team can advise as part of the specification process.

We offer High-Performance Double Glazing, Heritage Double Glazing, laminated security glass, acoustic glazing, decorative glass, obscure privacy glass, traditional leaded glazing and bespoke stained glass, with the specification tailored to the requirements of the project.
Can you match my existing windows?

Can I choose the colour and finish?
