Heritage Timber Window Restoration & Custom Manufacturing in Melbourne (VIC): A Complete Guide

Melbourne is home to some of Australia’s most distinctive heritage architecture — from Victorian terraces in Carlton and Fitzroy to Edwardian homes in Camberwell, Hawthorn and Kew, plus interwar and Arts & Crafts gems across the inner suburbs.

And one feature ties many of these homes together: traditional timber windows.

At Barnsbury Joinery, we specialise in manufacturing and restoring heritage timber windows, using traditional joinery methods paired with modern performance upgrades. With demand for authentic heritage restoration continuing to rise across Victoria, we’re excited to share that Barnsbury Joinery will be opening a Melbourne office in 2026 to better support homeowners, architects and builders across the region.

If you’re researching whether to restore your existing timber windows, replace them like-for-like, or upgrade performance without compromising heritage character — this guide is for you.

Why Heritage Timber Windows Matter in Melbourne Homes

Heritage timber windows are not just decorative — they’re part of the building’s identity. In many Melbourne heritage precincts, original window profiles and proportions are critical to maintaining the streetscape.

Replacing original timber windows with modern aluminium or poorly-matched substitutes can:

• reduce the home’s heritage value

• create planning issues in heritage overlays

• damage resale appeal

• lead to condensation and thermal discomfort

• introduce aesthetic mismatches (thicker frames, incorrect glazing bars, wrong proportions)

In many cases, restoring timber windows is the best long-term option — both visually and structurally.

Restore or Replace? How to Decide

A common misconception is that old timber windows are “too far gone” — when in reality, many can be restored to a near-new condition.

Restore your existing timber windows if:

• the majority of the timber frame is sound

• you want to keep original glass or heritage details

• the window proportions are historically accurate

• the home sits within a heritage overlay

• you want the most authentic outcome

Replace (like-for-like) if:

• the windows have severe rot throughout the sash and frame

• previous repairs have distorted the window geometry

• the joinery has been heavily altered

• the windows are missing or not original

• you need improved performance while keeping the heritage profile

Barnsbury Joinery regularly supports projects where we do a mix of both — restoring what can be saved, and manufacturing new heritage timber windows where needed.

Common Types of Heritage Timber Windows in Melbourne

Melbourne’s architectural variety means window styles vary by suburb, era, and home type. Some of the most common heritage window types we work with include:

Victorian-era timber sash windows

Often seen in:

• Fitzroy

• Carlton

• Collingwood

• Richmond

Key features:

• tall proportions

• Hawthorn

• Kew

• Camberwell

• Malvern

Key features:

• multi-pane upper sashes

• coloured glass highlights

• decorative timber detailing

Interwar timber casement windows

Found in:

• Glen Iris

• Brighton

• Elwood

Key features:

• side-hinged openings

• timber reveals

• lead-light glazing in some homes

What’s Involved in Heritage Timber Window Restoration?

A proper restoration is far more than “patching and painting.”

At Barnsbury Joinery, restoration typically includes:

• removal of sashes (where required)

• careful stripping of paint build-up

• repair of rot using appropriate timber splicing techniques

• reconditioning rails, stiles, and glazing bars

• sash rebalancing (cords, weights, pulleys)

• draught sealing upgrades

• glazing repairs or re-puttying

• hardware repair or replacement (matched to heritage style)

• refinishing for longevity and weather resistance

The goal is always the same: retain heritage character while improving function, comfort and durability.

Can You Upgrade Heritage Timber Windows for Better Thermal & Acoustic Performance?

Yes — and this is one of the biggest shifts in heritage restoration across Melbourne right now.

Older timber windows can be upgraded significantly without destroying their authenticity.

Common upgrades include:

1) Draught proofing

A major comfort upgrade. Draught sealing reduces:

• winter heat loss

• rattling

• dust ingress

• noise leaks

2) Improved glazing (where appropriate)

Depending on heritage requirements, options can include:

• slim-profile double glazing (for new manufacture)

• acoustic glass

• toughened safety glass

• secondary glazing solutions

  
  

3) Timber repair for airtightness

Even small distortions in a sash can create gaps. Correcting the geometry improves sealing and performance.

Heritage Overlay Considerations in Melbourne (VIC)

Many Melbourne suburbs fall under heritage overlay planning controls, which may restrict window changes visible from the street.

If your home is in a heritage overlay, it’s often important that any replacement windows are:

• like-for-like in profile

• correct in glazing bar thickness

• historically accurate in proportions

• consistent with the original window style

• finished appropriately (paint colours, sheen, etc.)

A specialist joinery team makes the process easier by ensuring the windows are built with heritage compliance in mind.

Why Melbourne Homeowners Still Choose Timber Windows

Even with modern alternatives available, timber remains the preferred choice for heritage homes because it offers:

• authentic character

• superior repairability

• longevity (when maintained)

• better profile detail than most substitutes

• compatibility with heritage overlays

• strong thermal properties compared to aluminium

Most importantly: timber windows can be restored and maintained, rather than replaced every couple of decades.

FAQ: Heritage Timber Windows in Melbourne

Is it cheaper to restore timber windows or replace them?

It depends on the condition and number of windows. Restoration can be highly cost-effective when frames are sound. Replacement becomes more viable when rot is widespread or windows are missing.

How long do restored timber windows last?

When restored properly and maintained, heritage timber windows can last decades — often longer than modern substitutes.

Can I double glaze heritage timber windows in Melbourne?

In many cases, yes — especially with new timber window manufacturing using slim-profile double glazing. In heritage overlays, it depends on visibility and planning requirements.

Do heritage overlays restrict window replacement?

Often, yes — especially for street-facing windows. Like-for-like replacements with correct profiles are typically preferred.
