You get a free itemised written quote, no subcontractors, and a 10-year product warranty as standard.

Decision Guide

Replace or Repair — Know the Difference

The most common question we hear. Here's a definitive framework so you can decide with confidence.

Replace your windows if…
  • Frame is rotting, warping, or corroding — structural failure cannot be patched
  • Glass is broken, cracked, or the double-glaze seal has failed (fogging between panes)
  • Significant heat loss in winter or heat gain in summer — the thermal barrier is gone
  • Windows won't close, lock, or seal properly — a security and weather issue
  • Updating from single-glazed aluminium and want real acoustic and thermal gains
  • Original 1970s–90s aluminium frames at end of useful life
  • Renovating and want a clean, lasting result backed by warranty
Consider repair if…
  • Frame is structurally sound and issue is a single isolated broken pane only
  • A handle, latch, or hinge has failed on an otherwise solid window
  • Weatherstripping or sealant has dried out but the frame itself is fine
  • Window is heritage-listed and must be retained under council overlay rules
  • Budget constraints make partial repair a reasonable short-term measure

Our Process

How Window Replacement Works at Windows Republic

Every stage handled in-house — measure to handover. Here's exactly what to expect.

1
Free Measure & Written Quote

Our team visits your property, measures every opening with precision, and provides a free itemised written quote. No obligation, no ballpark figures — you'll know exactly what's included before any decision is made.

2
Manufacture at our Cheltenham Factory

Your windows are made to measure at our Cheltenham facility. Australian Made manufacture means direct quality control — no importing, no third-party fabrication, no middleman margin added to your cost.

3
Careful Removal of Existing Windows

Our installers carefully remove your old frames and glass. We protect your interior, manage disposal of old material, and assess the opening condition before new installation begins.

4
Installation of New uPVC Double Glazed Units

New windows are fitted into prepared openings — plumb, level, and square. Fixings are selected to suit your wall type: brick, weatherboard, or rendered masonry.

5
Sealing, Finishing & Testing

All reveals are caulked, sealed, and finished neatly. Internal and external trims are fitted where required. Every window is tested for operation, locking, and weathertightness before our team leaves.

6
Handover & Warranty Documentation

We walk you through the finished installation, demonstrate all hardware, and hand over your warranty documentation. We're available for any follow-up after the job is complete.


Frame Replacement Explained

Window Frame Replacement — What It Actually Means

Many Melbourne homeowners search for "window frame replacement" when they mean the whole window — frame and glass together. That's exactly what we do.

In the vast majority of residential replacement projects, frame and glass are removed and replaced as a single unit. There's rarely value in keeping an old aluminium frame and inserting new glass — the frame itself is typically the source of thermal transfer, condensation, and air infiltration. A complete uPVC double glazed unit solves all three at once.

Our uPVC frames are multi-chambered, thermally broken by design, and available in a range of standard colours — single-sided (interior white, colour exterior) or double-sided (matching colour inside and out).

Available Frame Colours Single & double-sided options available
White
Classic, most popular
Cream
Warm period homes
Ash Black
Contemporary homes
Anthracite Grey
Modern & industrial

All colours available single-sided (white interior, colour exterior) or double-sided (matching colour both sides). Confirm availability for your specification at quote stage.

Aluminium to uPVC Upgrades

Changing Window Frames — Why Melbourne Homes Are Switching

Melbourne's older housing stock — particularly homes built between 1960 and 2000 — is heavily fitted with standard aluminium frames. These conduct cold directly into your home in winter, heat in summer, and cause condensation that leads to mould and plasterwork damage.

Switching from aluminium to uPVC double glazed windows is one of the highest-impact improvements you can make. Full removal of the existing frame, preparation of the reveal, and installation of a custom-manufactured uPVC unit to fit your existing aperture — no structural changes required in most cases.

Pricing Transparency

What Affects the Cost of Window Replacement in Melbourne

We don't publish fixed prices — every project is different. What we do provide is a free, itemised written quote so you know exactly what you're paying for. Here are the key cost drivers.

Window Size

Larger openings require more uPVC profile and heavier glass units. A narrow awning window and a full-height casement are priced differently — your written quote will break down every window by size and style.

Window Style

Casement, awning, sliding, fixed, and tilt-and-turn windows each have different hardware and profile requirements that affect price.

Glass Specification

Standard double glaze, acoustic laminated glass, and Low-E coatings affect unit cost. Acoustic glass is specified for busy roads.

Number of Windows

Whole-home replacement benefits from scheduling and delivery efficiencies compared with single-window jobs.

Access Difficulty

Second-storey windows, restricted-access sites, or windows over extensions may require additional equipment or time on site.

Wall & Substrate Type

Brick veneer, double brick, weatherboard, and rendered masonry each require different fixing methods and reveals. Most are straightforward — your quote will specify the approach for your property.

Value Without Compromise

Affordable Window Replacement — How We Make It Work

Windows Republic manufactures at our own Cheltenham facility rather than importing finished units. This removes the importer's margin from your invoice entirely. When you buy imported windows, you pay four layers of cost.

🏭 Typical Import Supply Chain — You Pay All of These
Overseas manufacturer margin
Importer / freight margin
Australian distributor margin
Installer / retailer margin
🏠 Windows Republic — Only Two Margins
Production cost (Cheltenham)
Installation cost (our team)
No importer
No distributor

Being Australian Made also means shorter lead times, easier warranty resolution, and windows engineered for Melbourne's climate — not European winters.


Period & Heritage Homes

Window Replacement in Melbourne's Victorian & Edwardian Homes

Melbourne has one of Australia's largest concentrations of intact Victorian and Edwardian housing stock. Many carry heritage overlays under local council planning schemes, which can affect what changes are permissible to the exterior facade.

Heritage Overlay Awareness

uPVC windows are available in profiles that replicate the visual character of original timber sash and casement windows — including woodgrain foil finishes designed to complement the appearance of painted or stained timber from the street.

We recommend checking your property's heritage overlay status before proceeding with any external changes. Your local council's planning department can advise, and a planning permit may be required. We're familiar with Melbourne's inner-city council requirements and can guide you through what applies to your property.

Common Questions

Frequently Asked Questions

How much does window replacement cost in Melbourne?
The cost varies with window size, style, glass specification, and project volume. Because Windows Republic manufactures in-house at Cheltenham, we remove importer and distributor margins that most suppliers pass on — keeping our pricing competitive at the quality we deliver. We provide free, itemised written quotes. For a general guide, see our window replacement Melbourne cost page.
Do I need a permit to replace windows in Melbourne?
In most cases, like-for-like window replacement in Victoria does not require a building permit — it falls under exempt development. However, if your property is in a heritage overlay, if you're changing the size of an opening, or if the work involves structural changes to the building fabric, a planning or building permit may be required. We recommend checking with your local council. We're happy to advise based on your specific suburb and property.
How long does window replacement take?
A single window is typically replaced in a few hours. A full-home replacement of 10–15 windows generally takes 4 to 5 days on site. Lead time from confirmed order to installation is typically 4 to 6 weeks from order confirmation — we'll give you a clear production and installation schedule at the time of quote.
Can you replace aluminium windows with uPVC double glazed windows?
Yes — one of the most common projects we carry out. We remove the existing aluminium frame and glass unit completely, prepare the opening, and install a custom-manufactured uPVC double glazed window to fit your existing aperture. No structural changes required in most cases. The thermal and acoustic improvement over standard aluminium is dramatic.
What is included in the installation price?
Our price includes: removal and disposal of existing windows, supply and installation of new uPVC double glazed units, internal and external sealing, fitting of all hardware (handles, locks, stays), and site clean-up on completion. The written quote specifies exactly what's included — no unexpected extras.
Do you replace windows in heritage homes?
Yes. We have experience with Melbourne's Victorian and Edwardian homes. Our uPVC profiles are available in woodgrain foil finishes designed to replicate the appearance of original timber windows. We recommend confirming your heritage overlay requirements with your local council first — we can then advise on the right approach for your property and any planning constraints that apply.
How do I know if I need new windows?
Key signs: visible frame damage (rot, warping, corrosion); condensation or fogging between panes (failed double-glaze seal); windows that won't close, lock, or seal; significant draughts adjacent to the window even when closed; and excessive noise intrusion despite closed windows. Our free site visit gives you an honest, no-obligation assessment.
What is the difference between window repair and replacement?
Window repair addresses a specific component failure — a broken pane, failed handle, dried-out weatherstripping — while the frame itself is structurally sound. Window replacement removes the entire unit (frame and glass) and installs a new one. Replacement is appropriate when the frame is compromised, when thermal or acoustic performance is the underlying problem, or when you want a new product warranty and a lasting result rather than a patch on an ageing system.

Alex and his team recently did double glazing for us. It was a huge job with multiple large windows in a two-storey house. The windows are top quality with quality think glass. Windows Republic is great value for money and their quote was well below other companies. The noise and heat differences are noticeable. The final look and feel of the house are definitely a lot more premium. Thanks, Team!
