Leading Victorian sash window company
Traditional sash windows define the character of thousands of homes across Sussex. From two-over-two terraces in Brighton to larger bay-fronted houses in Lewes and Hove, the proportions and detailing are what give these buildings their identity.
At Parsons Joinery, we design, manufacture and install bespoke timber Victorian sash windows that respect that architecture. Every window is made in-house to match your property, not adapted from a standard system.
Whether you need restoration, sash-only upgrades or full replacement Victorian sash windows, the starting point is always the same: get the details right.

Traditional sash windows with modern performance
Many modern sash windows are adapted from standardised systems. They may look similar at a glance, but the construction methods, jointing and material quality are often very different from traditional box sash joinery.
Our approach is rooted in how Victorian sash windows were originally made. That means proper timber sections, traditional box frame construction and components designed to be repaired, not replaced wholesale. The focus is long-term durability, accurate proportions and structural integrity.
Our Victorian sash windows are:
- Individually made to measure
- Constructed from carefully selected, stable timber
- Jointed and assembled using traditional box frame methods
- Designed for long-term repairability

Repair, sash upgrade or full replacement?
Not every traditional sash window needs replacing. If the original box frame is structurally sound and performing well, overhaul can be the most appropriate solution. We carry out a full draught-proofing and overhaul service.
Where suitable, we can retain the existing box and install new double-glazed timber sashes into it. This approach improves thermal performance while preserving the original structure.
Full Victorian sash window replacement becomes necessary when frames are extensively rotten, poorly altered or beyond economic repair. In those cases, we manufacture like-for-like replacements, carefully matching glazing patterns, horn details and frame proportions.
Our role is to assess each window honestly and recommend the option that makes sense long term.

New Victorian sash windows for period-style homes
We also manufacture new Victorian sash windows for:
- Period-style new builds
- Extensions to Victorian homes
- Renovations where original windows have already been removed
Planning departments across Sussex frequently require historically accurate timber designs in conservation areas. We are accustomed to working with architects and conservation officers and can provide drawings, sections and technical information where needed.
Projects regularly take place across Lewes, Brighton, Hove, Eastbourne and surrounding areas.
Why timber still matters for sash windows
For Victorian properties, timber is not just a preference. It is the appropriate material.
Properly detailed timber sash windows offer:
- Authentic, fine sightlines
- Structural strength without heavy sections
- Long-term repairability
- Suitability for listed buildings and conservation areas
Modern uPVC and aluminium systems struggle to replicate the subtle proportions of original Victorian joinery. Timber allows accurate reproduction and can be maintained and repaired over decades.
All windows are factory finished using high-quality paint systems for durability and reduced maintenance.

FAQs about Victorian sash windows
It’s important to feel comfortable with your choice of company when investing in traditional sash windows, so here are some helpful questions so you can come to the right decision. We would be delighted to talk to you in person about your project.
Matthew & Nathan Smith
We produce windows which are a close match to your existing Victorian sash windows in glazing bar design and horn profiles. Where variations exist across a property, we discuss whether to match individually or introduce consistency.
Often, yes. Local authorities usually require timber construction, traditional opening methods and accurate detailing. We regularly manufacture Victorian sash windows for conservation areas in Sussex and can provide supporting drawings where required.
With double-glazed glass or vacuum insulated glass and integrated draught-proofing, modern timber sash windows are significantly more efficient than original single-glazed versions. Performance depends on specification and site constraints, which we explain during survey.
We can do draught-proofing and overhaul work. We do not offer an extensive painting, splice repair or rot repair service to existing sash windows.
