Our sash window services

We help our customers maintain the original detail of their period properties. We use industry-leading repair and renovation techniques, alongside crafting bespoke styles to your specifications in our UK workshop.

Our comprehensive range of services includes:

  • New and replacement timber sash windows: We specialise in the replacement of traditional sash windows and box sash windows, with like-for-like double-glazed substitutes. All new windows are fully painted and meet current British Regulations.

  • Full box sash window replacements: With a full box sash replacement, we remove the architrave from the wall, allowing us to remove the entire box. We will then replace the entire unit with a beautiful new window designed around your requirements.

  • Replacement casement windows: All timber casement windows are designed and custom-built. As specialists in period design, we will ensure the windows retain their original features.

  • Overhaul and draught-proofing: This service maintains and improves the functionality of the existing windows. Draught proofing will virtually remove all draughts, improve thermal and sound insulation, minimise dust levels and stop rattling. New window furniture will help open and close the windows, improve security and smarten the finish.

  • Secondary glazing: Secondary glazing is like double or triple glazing. It is a fully independent internal window, fitted to the primary window. This offers improved thermal performance, enhanced security and noise reduction.

  • Plantation shutters: We supply and install plantation shutters made for you, so they fit your window perfectly. If you want to gain more privacy or control the light flow into your property without having to fit curtains, these provide an excellent solution.

  • All uPVC windows: Alongside handcrafted timber windows, we can also supply and install uPVC windows, including uPVC sash windows.

What are the benefits of timber sash windows?

Sash windows make a fantastic addition to any property and there are many reasons that timber windows continue to be hugely popular.

Authentic Appearance

Timber windows and doors ensure your period property retains its original charm, by replicating both the design and material of the original windows. Timber windows are often a requirement for listed building renovations.

Long-lasting and durable

Unlike other materials that may discolour and degrade over time, timber can be easily maintained with a new coat of paint or staining. Despite many people thinking that timber requires intensive maintenance, this is not the case. Maintaining your timber sash windows is easier than you think.

Energy efficient

Timber is a naturally insulating material and can provide comfortable temperatures. Many people assume that timber windows cannot be double glazed, but this is not the case. They will ensure that your property remains warm in winter and cool in summer.


Timber is a sustainable material and the eco-friendliest choice when it comes to window frames.
