Heritage sash window restoration in Malvern and East Malvern. Timber repairs, sash cord replacement, rot repair and bespoke joinery for period homes. Request a quote.
We are a conservation‑led specialist, not a replacement window company. Where a sash is rattling, sticking or draughty, our first instinct is to save the original timber and its detailing rather than tear it out. Where a window is genuinely beyond repair, we manufacture a faithful bespoke replacement matched to the original profiles.

Period homes in Malvern and East Malvern

The housing stock across Malvern and East Malvern spans the boom‑era Victorian period through to the Federation and Edwardian building that followed. Around Malvern Road, Wattletree Road and the older pockets near Malvern station you find double‑hung timber sashes with slender glazing bars, sometimes paired into bay windows with coloured or leadlight margins. Further into East Malvern, towards Darling and Waverley Roads, the Edwardian and Federation villas tend towards wider sash proportions, deeper timber mouldings and generous timber joinery around the openings.
These windows are integral to the character of the streetscape, which is precisely why they matter. Original cedar and Baltic pine sashes were built with counterweights and cords hidden in the boxed frame, glazed with hand‑drawn glass and finished with putty lines and mouldings that modern off‑the‑shelf windows simply cannot reproduce. When one is replaced with an aluminium or bulk‑standard timber unit, the loss shows immediately against the neighbouring homes. Our work is about keeping that fabric intact.
Much of Malvern and East Malvern sits within the City of Stonnington and, in parts, falls under a Heritage Overlay. That context shapes what is appropriate: sympathetic repair and like‑for‑like restoration are almost always preferable to wholesale replacement, both for the building and for any planning considerations.
What we do

We cover the full range of heritage timber window work. That includes sash window repairs for windows that rattle, stick or let in draughts, sash cord replacement and rebalancing so the sashes glide and hold their position, and timber rot repairs to sills, rails and frames where moisture has taken hold. We also fit slimline heritage double glazing where a discreet thermal upgrade is wanted, and we manufacture custom timber windows and bespoke joinery matched to the original profiles when a section is past saving.
Every profile, moulding and glazing bar is specified to match what was there before. The bespoke timber sections are manufactured in Barnsbury Joinery's UK studio and shipped to Australia, with glass sourced and installed locally. Our heritage specialists set the methods and profiles, and trusted local partners carry out all the on‑site work, so a Malvern home is restored to the same standard as the heritage projects behind our reputation.
Our local approach and Melbourne conditions

Melbourne's climate is hard on timber windows in a particular way. Wet winters drive moisture into unmaintained sills and bottom rails, while long dry summers cause timber to move and old paint to crack, which then lets in more water. On the south and west elevations common across Malvern's larger blocks, this weathering is often worst. We assess each window on its own terms rather than applying a single fix.
Because we specify the work centrally and rely on established local partners for installation, you get a consistent, documented approach: the right timber species, the right repair method for each defect, and finishes chosen to suit the elevation and exposure. This is deliberately different from a quick reglaze or a paint‑over that hides problems for a season. If you would like to understand more about how we operate in Australia, our Australia hub at /au sets out the full picture.
Our restoration process

We keep the process clear from the first contact. It begins with an initial consultation to understand the home and what you want to achieve. A local partner then carries out an on‑site inspection, examining each sash, cord, frame and sill and noting the condition of the glass and putty lines.
From there we prepare a detailed proposal setting out exactly what will be repaired, replicated or upgraded, and why. Once agreed, the studio preparation stage begins, with any bespoke sections manufactured to match the originals. The final stage is installation and finishing on site, leaving windows that operate smoothly, seal properly and read correctly against the period detailing of the house.
Heritage overlays and approvals

A common worry among Malvern and East Malvern owners is whether restoration will trigger a planning process. In most cases like‑for‑like repairs to original windows are exempt from planning approval, even within a Heritage Overlay, because you are conserving existing fabric rather than altering the building. That is one of the reasons repair is so often the sensible route.
Where the work goes further, for example replacing a window entirely or adding a glazing upgrade that changes the appearance, the City of Stonnington may require a planning permit. We flag this early and specify the work so that it respects the heritage character, which makes any council conversation far more straightforward. We give you a clear, honest written proposal before any work is committed.
Common questions
Do I need council approval to restore my sash windows in Malvern?
Usually not for like‑for‑like repairs. Even within a Heritage Overlay in the City of Stonnington, restoring or repairing original timber windows is generally exempt from planning approval because you are conserving existing fabric. Full replacement or a glazing upgrade that changes the appearance may need a permit, and we will flag that early and specify the work to suit the heritage character.
Can you match the original glazing bars and mouldings on an Edwardian home in East Malvern?
Yes. Matching original profiles is central to what we do. We record the existing glazing bars, mouldings and sash proportions, and any bespoke timber sections are manufactured to replicate them. The aim is that the restored or replicated window reads correctly against the rest of the house and the street.
My sashes rattle and stick and the room is draughty. Can that be fixed without new windows?
Almost always, yes. Rattling, sticking and draughts are typically caused by worn cords, painted‑shut sashes, movement in the timber or perished seals, all of which we repair. We replace sash cords, rebalance the sashes and address any rot, so the windows operate smoothly and seal properly while keeping the original timber.
Where are the windows made, and who carries out the work on site?
Our bespoke timber sections are manufactured in Barnsbury Joinery's UK heritage studio and shipped to Australia, with glass sourced and installed locally. Our heritage specialists specify the methods and profiles, and trusted local partners carry out all on‑site inspection and installation across Malvern and East Malvern.
