Barnsbury Joinery restores heritage timber sash windows across Keilor Park and the wider City of Brimbank, in Melbourne's north‑west. This is a pocket where interwar and post‑war homes sit alongside older weatherboard cottages that trace back to the original Keilor settlement along the Maribyrnong River, and the timber windows in these houses are worth keeping. We repair, rebalance and reglaze double‑hung sashes and casements so they run smoothly and seal properly again, without stripping away the character that gives a Californian bungalow or a period cottage its warmth.
Our approach is conservation‑led rather than replacement by default. Where a window is draughty, rattling or painted shut, we assess exactly what can be saved, splice in new timber only where the old has failed, and return the sash to balanced, weathertight operation. Barnsbury Joinery brings over two decades of British heritage joinery expertise to Australia, and we apply the same standards to a modest bungalow off Fullarton Road as we would to a listed terrace in London.
Period homes and streetscapes in Keilor Park

Keilor Park sits within the historic Keilor district, one of the oldest settled areas on Melbourne's north‑western fringe, where the Maribyrnong River valley and volcanic plains shaped a very different pattern of building to the inner‑city terraces. The suburb itself grew substantially through the interwar and post‑war decades, so the timber‑window stock here is dominated by Californian bungalows, interwar cottages and early Federation‑influenced homes, with older weatherboard dwellings surviving closer to the original Keilor township.
On the bungalows and interwar homes you will typically find double‑hung timber sashes with broad glazing bars, sometimes paired in banks beneath a wide eave, and often with leadlight or coloured‑glass detailing to the upper sashes or the front porch. Federation‑era and earlier cottages carry more slender double‑hung sashes with fine putty lines and weighted cords. These windows were made from dense, slow‑grown timber that was always intended to be repaired rather than thrown away, and when properly maintained they last well beyond a century.
We match our work to the era and detailing of each house, so a restored sash sits comfortably against its neighbours and preserves the low, horizontal rhythm that gives Keilor Park's residential streets their period feel. Keeping original joinery in service matters not just for one home but for the character of whole streets, where consistent timber detailing is easily eroded by unsympathetic aluminium replacements.
What we do for Keilor Park homes

We offer a complete range of heritage timber window services, so a single visit can address anything from one sticking sash to a full conservation programme across the whole facade. Our work includes sash window repairs for rattling, sticking and draughty windows, sash cord replacement and rebalancing of the weights, timber rot repairs to sills, rails and frames, glazing repair and reputtying, draught proofing, and slimline heritage double glazing where an insulation upgrade is wanted.
Where a window is genuinely beyond saving, or a previous owner has already fitted an unsympathetic replacement, we manufacture bespoke timber windows to match the originals. Profiles, glazing bar widths, meeting rails and hardware are copied from surviving examples on the property so a new sash reads as part of the original house rather than an obvious modern insertion. This bespoke joinery to match original profiles is where our heritage experience counts most.
Draught proofing is often the single most cost‑effective improvement for a Keilor Park bungalow. Discreet brush and compression seals are routed into the meeting rails and staff beads to cut rattles and cold draughts off the plains wind, while leaving the window fully operable and visually unchanged. Paired with rebalanced cords, it transforms how an old window feels to live with.
Our local approach and delivery model

Barnsbury Joinery combines British heritage joinery expertise with local Australian delivery. The bespoke timber window sections are manufactured in our UK studio to the exact profiles surveyed on your home, then shipped to Australia. Glass is sourced and installed locally, and our trusted local partners carry out all on‑site work while Barnsbury's heritage specialists specify the methods, timbers and profiles. It is a model built to protect original detailing rather than compromise it, and our long‑term plan is to train and employ local craftspeople here as the work grows.
This matters in Keilor Park because the local climate is demanding on timber. Hot, dry summers on the volcanic plains followed by damp winters open up joints, dry out old putty and accelerate rot where paintwork has failed at the sills. We specify repairs and finishes that account for these conditions, so the window you get back is not just cosmetically sound but genuinely weathertight for the years ahead.
Every enquiry is handled by people who understand period joinery. If you own a home near the Maribyrnong River, off Fullarton Road, or on one of the quiet streets running toward Keilor East and Airport West, we can help you keep its original windows in good order. You can explore our full Australian service on the Barnsbury Joinery Australia hub at our Australia page.
Our restoration process

Every project begins with an initial consultation to understand the house, the condition of its windows and what you want to achieve. Our local partners then carry out an on‑site inspection, examining the timber, the state of the cords and weights, the paint history and the glazing, so nothing is guessed at.
From there we prepare a detailed proposal setting out exactly what should be repaired, what should be upgraded and what can safely be left alone, with a clear written quote. Once approved, the studio preparation begins: bespoke sections are made to the surveyed profiles, and timber splice repairs are prepared for the sills, rails and frames that need them.
Finally, installation and finishing are completed on site by our local partners, with glazing sourced and fitted locally and the sashes rebalanced, draught proofed and finished to run smoothly. The result is an original window conserved and returned to service, not discarded. When you are ready, request a quote and our team will respond within one business day.
Heritage overlays and planning in Brimbank

Parts of the historic Keilor area fall within a Heritage Overlay under the Brimbank Planning Scheme, particularly around the original township and its river valley setting, though much of Keilor Park's interwar and post‑war housing sits outside overlay controls. Where a property is affected, altering or removing original external windows can require council permission, so it is always worth checking the overlay status of your specific address first.
The good news is that like‑for‑like repair and restoration of original timber windows keeps the external appearance unchanged and is often exempt from planning approval, because you are conserving the heritage fabric rather than altering it. Where you want to go further, for example a slimline double glazing upgrade or replacement of windows that have already been changed, council permission may be needed. We can advise on what your project is likely to involve and recommend confirming the specific requirements with the City of Brimbank before any work that changes external appearance.
Common questions
Can my Keilor Park sash windows be restored instead of replaced?
In most cases, yes. The timber sashes in Keilor Park's bungalows and older cottages were built to be repaired, so we splice in new timber only where sections have failed, renew the cords and weights, ease sashes painted shut and reglaze where needed. The original window is conserved and returned to smooth operation rather than discarded, which is almost always better value than a modern replacement.
Do I need council approval to work on my windows in Keilor Park?
It depends on your address. Parts of the historic Keilor area sit within a Heritage Overlay under the Brimbank Planning Scheme, while much of Keilor Park's interwar housing does not. Like‑for‑like repairs to original timber windows are often exempt because the external appearance is unchanged, but replacements or glazing upgrades may need council permission. We recommend confirming your overlay status with the City of Brimbank before any work that changes external appearance.
Can heritage timber windows be double glazed?
Yes. Slimline heritage double glazing can often be installed within existing timber sashes to improve insulation and cut noise while keeping the traditional appearance. Where the timber sections are too slender for a slimline unit, we specify alternatives that suit genuine heritage windows. Glass is sourced and installed locally, and we advise on whether an upgrade needs council approval for overlay‑affected homes.
Is Barnsbury Joinery based in Australia?
Yes. We are an Australian operation, The Barnsbury Joinery Group Pty Ltd, based in Mount Waverley, serving Melbourne including Keilor Park. Our bespoke timber sections are manufactured in our UK studio using traditional sash joinery, then shipped to Australia where glass is sourced locally and trusted local partners carry out the on‑site work under our heritage specialists' direction.
