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.

Additional Services
Sash windows are a defining feature of many Georgian, Victorian, and Edwardian homes—but over time, they can become worn, draughty, or difficult to operate. At Cavendish & Cole, we offer specialist sash window repair services designed to bring your original timber windows back to life.
At Cavendish & Cole, we specialise in sash window restoration, repairs, and upgrades for homes of historic significance—including those protected by English Heritage, local conservation areas, or official listed building status.
Original timber sash windows bring timeless character to your home—but they’re not always known for energy efficiency. Over time, natural movement, paint build-up, and ageing frames can cause gaps that let in cold air and outside noise.
At Cavendish & Cole, we believe that beautiful timber sash windows should offer more than just aesthetic appeal—they should also make your home feel safe and secure. That’s why we offer a range of sash window security upgrades, tailored to suit both modern and period properties, including listed buildings and homes in conservation areas.
Condensation on or around your timber sash windows can be frustrating, unsightly, and even damaging if left untreated. At Cavendish & Cole, we help homeowners across Sussex, Kent, and Surrey understand and manage condensation—while preserving the beauty and integrity of their period windows.
At Cavendish & Cole, every sash window we craft or restore deserves a finish that’s as timeless as the joinery itself. That’s why we offer a complete range of decorating options for timber sash windows—from classic heritage tones to modern neutrals, all applied with precision and respect for the character of your home.
