The work
Timber sash window and bespoke joinery service across London and the South East
Barnsbury Joinery has worked on London's timber windows and doors since 1987. From our studio at 94 Vale Road in north London, our joiners cover the whole of the capital and the surrounding counties, and our reach now extends across the rest of the United Kingdom and as far as Melbourne. The map of places we serve is long, and the directory below sets it out street by street and borough by borough. This page is the shorter version: an overview of where we work, what we do in each region, and how our full service and supply‑only service fit together.
The heart of what we do is timber sash window restoration and repair, alongside casement windows, entrance doors, and bespoke fitted joinery made to match the character of the buildings around them. Whether you own a Victorian terrace, a Georgian townhouse, a converted warehouse, or a mid‑century semi, the principle is the same. We survey the joinery you already have, tell you honestly what can be saved and what genuinely needs replacing, and carry out work that respects the age and detailing of the property rather than papering over it.
London and the inner boroughs
London is where the business began and where the bulk of our work still takes place. Our joiners are on site across the inner boroughs week in and week out, from the Georgian and early Victorian stock of Islington and Camden through to the grand stucco terraces of Westminster and the varied housing of Hackney, Wandsworth, and beyond. Each area brings its own quirks. Islington and Camden are full of tall sash windows with slender glazing bars and shutters that were designed to be lived with, not sealed shut. Westminster holds some of the most tightly protected streetscapes in the country. Hackney mixes robust terraced housing with warehouse and industrial conversions, and Wandsworth spans everything from riverside mansion flats to modest bay‑fronted terraces.
Across these boroughs the common thread is age. Much of the housing predates the First World War, a great deal of it is Victorian, and a significant share sits within conservation areas or carries a listing. That shapes how we approach every job. We work with original timber wherever it can be repaired, we match profiles and mouldings to what is already there, and we specify glass, ironmongery, and finishes that suit the period rather than fighting it. For clients across inner London we offer the full service end to end: survey, restoration, repair, draught‑proofing, and bespoke fitted joinery, all managed from our own studio rather than subcontracted out.
Because we hold everything under one roof, a single point of contact runs your project from the first survey to the final coat of paint. That matters most in London, where access, parking, party‑wall considerations, and neighbourly timetables all have to be handled with care. Our teams are used to working in occupied homes, terraced streets with no off‑road space, and mansion blocks with strict rules about noise and communal areas.
The South East and the Home Counties
Beyond the capital, our full service extends across the South East and the commuter belt. Hertfordshire is a natural extension of our London work, and we regularly travel out to the market towns and villages of the Home Counties where period property is the rule rather than the exception. Much of this housing shares the same DNA as the London stock we know so well: Georgian and Victorian frontages, timber sashes and casements, panelled doors, and interiors that reward joinery made to measure rather than bought off the shelf.
The difference in these areas is often the setting. A townhouse on a conservation street in a Hertfordshire market town, a Victorian villa on a leafy commuter road, or a period cottage in a village all call for the same restraint and attention to detail, but they come with their own planning contexts and their own weathering. Windows facing open country take a harder battering from wind and rain than those tucked into a sheltered London terrace, and our surveys account for that when we recommend repairs, timber species, and finishes built to last.
For homes across the South East we provide the same full service we offer in London: an on‑site survey, honest advice on what to repair and what to replace, careful restoration and repair, and bespoke fitted joinery made in our north London studio and installed by our own people. The commuter belt is close enough to London that clients get the benefit of a genuine London studio without any drop in the level of hands‑on service.
Conservation areas and listed buildings
A large part of our work sits within conservation areas or involves listed buildings, and this is where specialist joinery earns its keep. When a property is listed or falls within a conservation area, the timber windows and doors are usually part of what makes it special, and the rules that protect them are there for good reason. Replacing original joinery with modern like‑for‑like substitutes is rarely the right answer and is often not permitted at all. The better route, and frequently the required one, is careful repair and sensitive restoration that keeps the original fabric in service for another generation.
We understand how these constraints work in practice. Original timber sashes can almost always be repaired rather than ripped out, with rotten sections spliced in, cords and weights renewed, and draught‑proofing added discreetly so the window performs far better without losing its appearance. Where a window or door genuinely cannot be saved, we make an accurate replacement by hand, matching the section sizes, glazing bar profiles, and mouldings of the original so the result reads as authentic from both inside and out. This craft‑led approach is what allows homeowners to improve comfort and thermal performance while staying on the right side of conservation and listed building requirements.
Owners of protected properties across London and the South East come to us precisely because we treat original joinery as something worth conserving. We are happy to discuss what a scheme is likely to involve before any formal consents are sought, so you have a realistic picture of the work from the outset.
Supply‑only made‑to‑measure joinery across the rest of the UK
Our full survey and installation service is focused on London and the South East, but our studio serves the whole country. For clients elsewhere in the United Kingdom we offer supply‑only made‑to‑measure joinery: timber sash windows, casements, doors, and bespoke pieces manufactured to your exact sizes and specification in north London, then delivered to you or your own installer.
This is a practical option for homeowners, architects, builders, and joiners outside our travel radius who want London studio quality without a London studio on their doorstep. You provide the measurements and detailing, or work with us to nail them down, and we build to order using the same timber, the same profiles, and the same standards we apply to our own installed projects. Whether you are restoring a period property in the North, the Midlands, Scotland, or Wales, or matching existing joinery on an extension, supply‑only lets you draw on our manufacturing while managing fitting locally.
The made‑to‑measure principle is central here. Nothing we send out is a stock size forced to fit. Every unit is cut to your opening and your specification, which is what makes it suitable for older buildings where no two openings are quite the same.
Heritage homes in Melbourne
Our reach also extends to Australia. Heritage homes in Melbourne are served through our sister company, Sash Restoration Australia, which brings the same craft‑led approach to timber sash windows and period joinery in a very different climate. Melbourne's Victorian and Edwardian terraces, with their characteristic double‑hung sashes and decorative timberwork, share a great deal with the London housing we know best, and the restoration principles carry across directly.
If you own a period property in Melbourne, Sash Restoration Australia is the right point of contact for local survey, restoration, and repair. It operates as part of The Barnsbury Group, so you benefit from the same heritage joinery expertise, adapted to Australian conditions and delivered on the ground.
