Working with English Heritage & Listed Buildings
Sensitive restoration. Compliant craftsmanship. Respect for history.
At Cavendish & Cole, we specialise in sash window restoration, repairs, and upgrades for homes of historic significance—including listed buildings those protected by English Heritage, local conservation areas, or official listed building status.
With decades of combined experience, we understand the complexities of working on heritage properties and listed buildings, and we know that every detail matters. From traditional joinery to discreet Slimlite double glazing, we offer solutions that meet modern standards while staying true to the past.
Serving clients across Sussex, Kent, and Surrey, we are your trusted specialists for sash window work that honours the history of your home.
Listed Buildings & Conservation Areas
If your property is listed—or located in a conservation area—there are often strict rules regarding what you can and cannot change, especially when it comes to original features like timber sash windows.
We’re here to help with:
- Guidance on planning permission and listed building consent
- Heritage-appropriate materials and glazing solutions
- Accurate like-for-like timber replacements and restoration
- Bespoke joinery that respects original dimensions and profiles
- Advice on working with English Heritage or your local authority
- We can liaise directly with conservation officers on your behalf and provide documentation, specifications, and samples to support your application.
Traditional Joinery, Conservation-Sensitive Upgrades
We use traditional handcrafted joinery techniques and period-authentic materials—carefully replicating existing mouldings, profiles, and glazing bars. Where improvements are allowed, we introduce modern upgrades in the least intrusive ways possible.
Our heritage-appropriate services include:
- Slimlite double glazing for authentic sightlines and improved efficiency
- Single to double glazed upgrades in existing sash frames
- Draught-proofing, sash cord repairs, and frame restoration
- Use of Accoya timber, approved for historic building works
- Traditional glazing methods with putty and original-style fixtures
All works are bespoke and carried out in-house, ensuring consistent quality and sensitive handling from start to finish.
