Get a fast, honest price range for new windows, whether you’re after double glazing, timber, aluminium or uPVC. Add each window, choose a frame and glass, and the estimator works out a ballpark using typical 2026 Victorian installed prices.
These are typical supply-and-install prices for a standard window of about 900 × 1200 mm, including removal of the old window and making good. Larger windows, sliding doors and specialty glass cost more.
| Window type | Typical installed price | Best for |
|---|---|---|
| Aluminium, single glazed | $500 – $900 | Budget replacements, sheds, laundries |
| Aluminium, double glazed (thermally broken) | $900 – $1,700 | Modern homes, large openings, low maintenance |
| uPVC, double glazed | $900 – $1,800 | Best thermal value, coastal homes, noise |
| Timber, double glazed | $1,200 – $2,500 | Character, period and coastal-style homes |
| Aluminium-clad timber | $1,400 – $2,800 | Timber inside, low-maintenance outside |
| Retrofit double glazing (keep your frames) | $350 – $800 | Sound timber frames, heritage homes |
| Secondary glazing | $250 – $600 | Renters, heritage overlays, noise |
| Double glazed sliding door (1800 × 2100) | $2,000 – $3,900 | Living areas opening to the deck |
Prices include GST and are drawn from published 2026 Victorian and Melbourne price guides. A whole home of 10–15 windows usually lands between about $9,000 and $28,000 depending on frames and glass.

* Subject to conditions. This estimator gives an indicative price range only and is not a quote. It uses typical 2026 Victorian installed prices including GST, removal of old windows and standard making good. Your final price depends on a site measure and inspection, frame condition, access, wall construction, glass specification, bushfire attack level (BAL), heritage controls, any rotten framing or lintel repairs, and current material prices. BAL-40 and BAL-FZ windows are priced on request.
Choosing new windows comes down to three decisions: the glass (single or double glazed), the frame (aluminium, timber, uPVC or a mix), and whether to replace the whole window or keep your frames. Here’s how each option stacks up for homes on the Mornington Peninsula, from salty beachside streets in Rye and Sorrento to the bushfire-rated hills around Red Hill and Arthurs Seat.
Windows are the weak point in most homes. The Australian Government’s Your Home guide says up to 40% of a home’s heating energy can be lost, and up to 87% of its heat gained, through windows. Double glazing puts two panes of glass in one sealed unit with an insulating gap between them. The Victorian Government notes that double-glazed windows reduce heat loss or gain by almost 30% compared with single glazing.
Upgrade tip: Low-E coated glass with an argon-filled gap is the sweet spot for Victorian homes. It adds a little to the glass cost but makes a real difference in a Peninsula winter.
Aluminium is the most common window frame in Australia. It’s strong, slim and affordable, and it suits large sliding doors and modern designs. The catch is that aluminium conducts heat very well, so a standard aluminium frame loses a lot of warmth even with double glazed glass. A thermally broken aluminium frame has an insulating barrier built into it to fix that.
On the Peninsula: if you live close to the water, ask for a marine-grade powder coat or anodised finish, plus 316 stainless steel hardware. Standard finishes can start breaking down within years in direct sea air.
Timber is a natural insulator and has been used in Australian homes for well over a century. Quality hardwood or engineered timber windows suit weatherboards, period homes, coastal cottages and anything with a warm, crafted look. As carpenters, this is our home ground: we build, repair and replace timber windows across the Peninsula.
uPVC (unplasticised PVC) frames are multi-chambered plastic profiles reinforced with steel. They’re standard in Europe and are growing fast in Victoria because they insulate almost as well as timber for less money.
Aluminium-clad timber windows have timber on the inside and an aluminium shell on the outside. You get the warmth and insulation of timber in the room with a weatherproof, low-maintenance exterior.
If your existing timber frames are sound, you may not need new windows at all.
Neither fixes rotten, warped or draughty frames, so we always check frame condition first. Often the best value is repairing sashes and retrofitting the glass rather than replacing everything.
| Frame | Price (double glazed) | Insulation | Maintenance | Near the beach | Lifespan |
|---|---|---|---|---|---|
| Standard aluminium | $800 – $1,500 | Poor | Very low | Needs marine grade | 20–30 yrs |
| Thermally broken aluminium | $900 – $1,700 | Good | Very low | Needs marine grade | 20–30+ yrs |
| uPVC | $900 – $1,800 | Excellent | Very low | Excellent | 25–40 yrs |
| Timber | $1,200 – $2,500 | Excellent | Repaint every few years | Very good | 30–60 yrs |
| Aluminium-clad timber | $1,400 – $2,800 | Excellent | Low | Good with marine finish | 30+ yrs |
Homes in beachside suburbs like Mornington, Mount Martha, Rosebud, Rye, Sorrento, Portsea, Flinders and Shoreham get constant salt spray. Timber and uPVC don’t corrode. If you choose aluminium, insist on a marine-grade finish and stainless hardware in writing, and rinse the frames with fresh water a few times a year.
Much of the Peninsula’s hinterland, including Red Hill, Main Ridge, Arthurs Seat and parts of Mount Eliza, is bushfire prone. New windows there must meet Australian Standard AS 3959 for your site’s bushfire attack level, which can mean toughened glass, metal screens or specially rated frames. We’ll check your BAL before quoting.
Some older streets in Mornington, Sorrento and Flinders sit under heritage overlays. Changing a window’s look may need a planning permit, so retrofit double glazing or like-for-like timber replacements are often the easiest path.
Through the Victorian Energy Upgrades program, Victorian households replacing single-glazed windows may get a discount on eligible double or secondary glazing installed by an accredited provider. Check eligibility before you sign.
We’re local carpenters, not a window factory, so we’ll tell you honestly whether to repair, retrofit or replace. We’ll measure every window, check frame condition, BAL and heritage controls, and give you a fixed written quote.
Book a free measure & quoteIn 2026 most standard windows cost about $500–$900 installed for single-glazed aluminium, $900–$1,800 for double-glazed aluminium or uPVC, and $1,200–$2,500 for double-glazed timber. Size, glass, access and site conditions move the price up or down.
For most homes, yes. The Peninsula’s cold, windy winters and hot summer afternoons make windows a major source of heat loss and gain. Double glazing improves comfort, cuts condensation and noise, and reduces energy bills, and it may qualify for a Victorian Energy Upgrades discount.
Timber and uPVC don’t corrode in salt air, so they’re the safest choices for beachfront homes. Aluminium works well too, but only with a marine-grade powder coat or anodised finish and stainless steel hardware.
Often, yes. If your timber frames are sound, retrofit double glazing fits new double-glazed units into the existing sashes for roughly $350–$800 per window. Secondary glazing is another option, fitted on the inside of the existing window.
Most windows are made to measure, which usually takes a few weeks. Installation is quick: typically 2–4 hours per window, and a whole house can often be done in a few days with each room open for only a short time.
Like-for-like replacements usually don’t need a building permit. You may need approval if you change the size of an opening, if your home is under a heritage overlay, or if your site is in a bushfire area with a high BAL. We’ll check before work starts.
