Custom Timber Windows
Every property is unique—especially period homes. That’s why at Cavendish & Cole, we specialise in designing and manufacturing custom timber windows that match your style, suit your space, and respect your home’s architectural history.
Made to measure. Built to last. Beautifully in keeping.
From grand Georgian sash windows to bespoke arched casements or uniquely shaped heritage replacements, our team brings decades of experience in made-to-measure joinery—all handcrafted in our Sussex workshop and installed across Kent, Surrey, and Sussex.
Why Choose Custom Windows?
Standard sizing and off-the-shelf solutions rarely work for period properties. Uneven openings, deep reveals, or unique proportions demand a more thoughtful approach. Our bespoke timber windows are tailored precisely to your home’s requirements, offering:
- A perfect fit—no compromises or unsightly filler trims
- True-to-period detailing and authentic mouldings
- Integration with original box frames, lintels or reveals
- Options for heritage-approved glazing (Slimlite, single, or double glazed)
- Timber choices including Accoya, hardwoods, and sustainable softwoods
We offer complete flexibility in style, configuration, glazing and finish—whether you’re replacing like-for-like, adding new windows to an extension, or blending old and new.
Styles We Custom Build
Our custom windows include, but are not limited to:
- Traditional sash windows – Georgian six-over-six, Victorian two-over-two, and bespoke arrangements
- Casement windows – side-hinged or top-hung, flush or stormproof
- Bay windows – curved or square, with seamless frame integration
- Arched or shaped windows – made to replicate original designs or create something unique
- Slimline and conservation windows – designed to meet local planning and English Heritage standards
Every window is crafted with care and an eye for detail, using traditional mortice and tenon joinery, premium ironmongery, and hand-applied finishes that protect and enhance.
Perfect for Listed Buildings & Conservation Areas
We regularly work with conservation officers, architects, and homeowners on listed buildings, providing custom sash windows and casements that meet strict planning regulations while retaining authentic charm.
- Exact profile matching and horn detailing
- Putty-glazed or bead-glazed options
- Slimlite double glazing for invisible upgrades
- Timber species and finishes that meet heritage requirements
- We can support your planning permission applications if needed
- Handcrafted in Our Joinery Workshop
Our Sussex-based workshop is where craftsmanship meets creativity. Your windows are made from raw timber to final finish by our skilled team—nothing is outsourced. This ensures:
- Superior quality control
- Faster turnarounds for bespoke projects
- Total consistency in finish and fit
- Personalised service from consultation to installation
Whether you want natural timber stain, heritage paint colours, or fully factory-finished sash windows, we offer a decorating service to match your vision.

Additional Services
At Cavendish & Cole, we don’t just restore sash windows—we enhance them with beautifully crafted wooden shutters, designed and made to order in our Sussex joinery workshop.

Every property is unique—especially period homes. That’s why at Cavendish & Cole, we specialise in designing and manufacturing custom timber windows that match your style, suit your space, and respect your home’s architectural history.
There’s a reason oak has been used in British joinery for centuries. It’s strong, stable, and full of character—and at Cavendish & Cole, we craft bespoke oak windows that reflect the very best of traditional craftsmanship and timeless design.
At Cavendish & Cole, we believe great design lives in the details. That’s why we supply and install a carefully curated range of traditional window hardware, designed to complement your timber sash and casement windows in both form and function.
At Cavendish & Cole, we take pride in creating timber sash windows and doors that combine heritage design with cutting-edge performance. That’s why we recommend and work extensively with Accoya® timber—a revolutionary wood that’s perfect for both traditional and contemporary joinery.
At Cavendish & Cole, we create bespoke timber doors that make a statement—designed to reflect the character of your property, stand up to daily use, and deliver long-lasting beauty.
At Cavendish & Cole, we understand that in period architecture, it’s the details that make all the difference. That’s why we offer a specialist custom timber moulding service—handcrafting architraves, trims, sills, glazing beads, and decorative profiles to suit the age, style, and character of your home.
At Cavendish & Cole, we know a beautiful window or door is only as good as its finish. That’s why we offer a premium workshop painted finish service for all our timber sash windows, casements, shutters, and doors—applied in a controlled environment using industry-leading materials and traditional care.
