Top five sash windows

Handcrafted, energy-saving sash windows for period homes and listed buildings.

With a wealth of experience, we handcraft timber sash windows in the traditional way with full mortise and tenon joints.

We offer entirely new sash windows, draught-proofing, double glazing and restoration services. Over the years, we have also developed extensive experience in working with listed buildings and the associated rules, regulations and restrictions – we can guide you through the entire process, be it restoring, upgrading or fitting brand new windows.

We’ve installed superior sashes in a wonderful variety of properties, breathing new life into everything from a Grade II listed manor house, Victorian townhouse and elegant eighteenth-century home, as well as renewing spaces with brand new windows equipped for the modern world that still blend seamlessly with the original architecture…

18th century elegance restored

Sympathetic and exceptionally skilled restoration skills were needed to bring this handsome, eighteenth-century property back to life. Arched sash windows on the ground floor were replaced with new windows fitted with slim-profile double glazed units which provide all the benefits of modern double glazing whilst keeping the windows looking authentic.

Upstairs, bedroom sash windows were diligently restored to their former glory, fitted with draught proofing and finished with new shutters, panelling and architrave.

To ensure authenticity, the shutter design was based on the original shutters from the living room and the mouldings and architrave took their cue from period details of the property. All were handcrafted in sustainable, modified timber, Accoya selected for its durability and dimensional stability, and spray painted in the client’s choice of colour, Brilliant White.

Victorian splendour

This quintessential townhouse, crafted from iconic Bath stone, featured beautiful Victorian bay sash windows which were in need of restoration; upon inspection, the original sash boxes were still in great condition although the sashes were beyond repair.

Our specialist team removed the existing sashes from the window and replaced elements of the sash while keeping as much of the original timber as possible. We handcrafted replicas to match using Accoya, carefully measured and replicated the existing using traditional methods and finished with ironmongery and detailed mouldings. The new replacement sash windows were also fitted with double glazing and draught proofing.

Restoration on an ambitious scale

Unloved for decades and having survived extensive flooding in the 1960s, this very special Grade II listed manor house was undergoing significant restoration.

With the aim of sympathetically reinstating the property to its original styling, we helped to restore and replace some of the original Georgian windows, carefully copying and recreating the mouldings and original workings. Each window featured single glazing conservation glass and thin Astragal bars and was fitted on site with an exacting attention to detail.

We worked closely with the client to propose joinery options and highlight the implications of going down various design routes, ensuring that decisions made were informed choices which shouldn’t require compromise further down the line.

Authentic & acoustic 

In this property, nine new sash windows across three bays were handcrafted with Accoya frames (with a fifty-year timber guarantee), glazed with acoustic glass to minimise local traffic noise and finished with brass ironmongery. Installed and finished with care, they flood the generous expanse of living room with the morning sun.

By handcrafting timber sash windows in the traditional way, with full mortise and tenon joints, we ensure our joinery looks exactly how the original architect of your home intended and that crucial details remain authentic and high-quality.

Six over six

We were asked to restore some of the sash windows within this property as well as manufacture new windows, doors and shutters. Some windows were in need of a complete restoration, for others we crafted new boxes and sashes using Accoya.

The windows featured a unique six over six pane design, with the middle panes being larger than the others. We crafted the sashes to replicate their predecessors and also included our custom draught-proofing system.
