Conservation area
Sliding sash windows
We specialise in designing and installing bespoke conservation area windows for period, listed, and heritage properties across Yorkshire. Every window is crafted using traditional joinery techniques and high-quality timber to preserve the character of your home while meeting modern performance standards.
The example pictured shows a Grade II listed care home in Whitby, where we restored and installed sliding sash windows. We carefully matched all original window details and upgraded the windows with double glazing for improved thermal performance. Unlike traditional rope-and-pulley systems, we installed spiral balancers to reduce maintenance while preserving the authentic look. The windows were professionally painted as part of the restoration, and we guided and supported the client through the planning application process to ensure full compliance with conservation area regulations.
Our conservation windows include sliding sash, casement, and bespoke heritage designs, all tailored to comply with planning and conservation area requirements. Whether replacing windows in a listed building or enhancing a period property in York, Harrogate, Ripon, Skipton, Whitby, or surrounding towns, we ensure each installation is sympathetic, durable, and visually authentic.
With Carpentry and Joinery Conservation Ltd, your conservation area windows combine historic style with modern performance, careful planning compliance, and long-term durability, adding charm, value, and character to your property.
Conservation area windows
The example pictured shows a full conservation area project where we carefully matched all the original window details, carved new heart-shaped coving, and repaired the existing frame structure. Each window was upgraded with double glazing, and we encapsulated and repaired the stained glass to make it double glazed while preserving its historic charm. The entire structure, including the windows, was professionally painted, and we reroofed the building to complete the restoration. We also guided and supported the client through the planning application process to ensure full compliance with conservation area regulations.

Casement timber windows
At Carpentry and Joinery Conservation Ltd (CJ Conservation), we design and install bespoke timber casement windows for period, listed, and heritage properties across Yorkshire. Each window is crafted using traditional joinery techniques and high-quality timber, combining historic character with modern performance.
Our casement windows are fully custom-made to suit the style and period of your property, whether it’s a countryside cottage, a town centre listed building, or a conservation area home. We ensure all windows meet planning and conservation area requirements, working closely with clients and local authorities to secure approvals where needed.
We carefully restore or replicate original details, including traditional glazing bars and joinery patterns, while providing double glazing for improved thermal efficiency. Each window is finished with a professional paint system to enhance durability and preserve the authentic appearance.
Servicing York, Harrogate, Ripon, Skipton, Whitby, and surrounding towns, Carpentry and Joinery Conservation Ltd ensures that every casement window installation is sympathetic to the property, long-lasting, and visually authentic.
Original sashes, upgraded
We specialise in sliding sash windows, offering both new installations and the refurbishment of original sashes. Our services include sash window repair and refurbishment, addressing draughts, timber decay, worn joints, and glazing replacements. Original sashes can be carefully upgraded to double glazing, retaining the timber frames, mouldings, and glazing bars while improving heat retention, soundproofing, and energy efficiency. Each sash is carefully prepared and fitted to allow smooth operation and long-lasting durability, blending historic charm with modern comfort. New sash windows can be supplied with either single or slim-line double glazing, giving you the choice of insulation and efficiency.
Our services also cover casement windows, which are handcrafted to match original joinery patterns, decorative elements, and glazing styles. Whether restoring or installing new casements, we ensure every window is sympathetic to the period of the property while providing long-lasting performance.
We also provide guidance and support for planning applications and conservation compliance, particularly for properties in conservation areas or listed buildings. From restoration and repairs to fully bespoke new installations, we ensure every window is sympathetic, durable, and visually authentic.
Servicing York, Harrogate, Ripon, Skipton, Whitby, and surrounding towns, Carpentry and Joinery Conservation Ltd delivers expert craftsmanship, heritage authenticity, and long-lasting quality for all your timber window projects.
