Sash window restoration in Surry Hills
Heritage sash window restoration in Surry Hills. Barnsbury Joinery repairs, rebalances and remakes timber windows for Victorian terraces and warehouse conversions.
Surry Hills is one of Sydney's most tightly woven Victorian streetscapes, where narrow terraces, corner pubs and former rag‑trade warehouses still carry their original timber sash windows. Barnsbury Joinery restores those windows to work as they were built to: smooth‑running, weather‑tight and true to the period. We bring over two decades of British heritage joinery expertise to Australia, pairing it with trusted local partners who carry out the on‑site work here in Sydney.
Whether you own a two‑storey terrace off Crown Street, a workers' cottage near Bourke Street or a warehouse conversion in the Reservoir Street precinct, we work with the fabric you already have. Original joinery is repaired and conserved wherever it can be saved, and only remade where decay leaves no other option.
Surry Hills terraces and warehouse conversions

Surry Hills grew densely through the late nineteenth century, and its housing stock reflects it: single and double‑fronted Victorian terraces, often on narrow allotments, with double‑hung timber sashes to the front rooms and smaller sashes to the rear. Many retain fine detailing such as slender glazing bars, moulded sash horns and rendered or face‑brick facades that the windows were designed to sit within. On the commercial edges around Wentworth Avenue, Foster Street and Reservoir Street, former warehouses and light‑industrial buildings have been converted to apartments and studios, frequently keeping tall, large‑paned timber sashes that define the character of the building.

Because streets here are narrow and terraces share party walls, windows carry much of a home's period character on the facade. A poorly matched replacement stands out immediately. Our approach is to keep original timber and profiles intact, matching the exact sightlines, horn detail and glazing bar widths that make a Surry Hills sash read correctly from the footpath.
What we restore and repair

We cover the full range of sash window work. That includes easing sticking sashes and curing rattles and draughts, replacing broken or perished sash cords and rebalancing the weights so both sashes glide and hold position. Where timber has decayed at the sill, bottom rail or where cills meet the frame, we carry out targeted rot repairs and splice in new sections of matched timber rather than tearing out sound joinery.
For windows beyond economical repair, we manufacture bespoke replacement sashes and box frames to the original profile. Our heritage timber window sections are made in Barnsbury Joinery's UK studio and shipped to Australia, with glass sourced and installed locally. Where owners want better comfort against Sydney's traffic noise and temperature swings, we can specify slimline heritage double glazing designed to sit within traditional sightlines rather than bulking out the frame.
Our local approach and Sydney conditions

Barnsbury's heritage specialists set the methods, profiles and finishes for every job, while trusted local partners handle inspection, installation and finishing on site in Surry Hills. This keeps the conservation standard consistent with our British work while giving you a responsive local team who knows Sydney buildings.
Surry Hills sits a few kilometres from the harbour and the coast, and while it is more sheltered than beachside suburbs, salt‑laden air and humidity still drive paint failure and timber movement over time. West and north‑facing sashes take strong afternoon sun. We specify durable, breathable finishes and detailing that manages moisture, so restored windows keep performing in the local climate rather than needing constant attention.
How the process works

We begin with a consultation to understand your building and what you need. A local partner then carries out an on‑site inspection in Surry Hills, assessing each sash, the box frames, cords and timber condition. From there we prepare a detailed written proposal covering exactly what will be repaired, remade or upgraded, with the profiles and methods specified by our heritage team.
Once approved, bespoke sections are prepared in the studio, glass is arranged locally, and installation and finishing are completed on site with minimal disruption to your home. To begin, request a quote and we will respond within one business day.
Heritage conservation and council approvals

Much of Surry Hills falls within a Heritage Conservation Area under the City of Sydney Local Environmental Plan, and some individual buildings carry heritage listings. Like‑for‑like repair and maintenance of original timber sash windows is often exempt from approval, which is one reason careful restoration is usually preferable to replacement.
Where work goes beyond straight repair, such as replacing whole windows or changing glazing, council approval may be required. We can advise on where your project is likely to sit and specify solutions that respect the heritage character of the area. For anything requiring formal consent, we recommend confirming requirements with the City of Sydney before work begins. You can see more about our services across Australia at our Australia page.
Common questions
Do you restore sash windows in Surry Hills terraces and warehouse conversions?
Yes. We work on Victorian and Edwardian terraces, workers' cottages and former warehouse conversions throughout Surry Hills, restoring original double‑hung timber sashes and box frames and matching period profiles.
Can original Surry Hills sash windows be saved rather than replaced?
In most cases, yes. We prioritise repairing and conserving original timber, splicing in new sections only where decay requires it. Full replacement is a last resort and is made to the original profile when needed.
Will I need council approval for sash window work in Surry Hills?
Much of Surry Hills is a Heritage Conservation Area under the City of Sydney LEP. Like‑for‑like repairs are often exempt, but replacements or glazing changes may need council approval. We can advise, and we recommend confirming with the City of Sydney.
Where are the windows made and who does the on‑site work?
Bespoke timber sections are manufactured in Barnsbury Joinery's UK studio and shipped to Australia. Glass is sourced and installed locally, and trusted local partners carry out the on‑site work in Surry Hills while our heritage specialists specify the methods and profiles.
