Cottesloe sits on the Indian Ocean about 11 km west-south-west of the Perth CBD, in the Town of Cottesloe. It’s a compact suburb, under 4 km², with the ocean along one side and the Fremantle railway and Stirling Highway along the other. The 2021 Census counted 3,492 private dwellings: 69.1% separate houses, 12.5% semi-detached homes and townhouses, and 18.6% flats and apartments (ABS QuickStats).
Living this close to the water changes what you need from your windows: salt in the air, strong afternoon sun off the ocean, winter weather coming in from the west, and on many streets, traffic and trains. 24/7 Glazing is a family-owned Perth glazier based in Malaga. We can supply and install double glazed windows and doors for Cottesloe houses, townhouses and apartments, and we’ll help you choose frames and glass that suit a coastal site.
What this page covers
Choosing frames and hardware for salt air, keeping west-facing rooms comfortable, cutting noise from Curtin Avenue, Stirling Highway and the railway, heritage-listed homes, apartments and townhouses, what drives the price, the questions to ask before you accept any quote, and when retrofitting is enough.

Salt is the first thing to plan for in Cottesloe. It settles on frames, tracks and fixings, and it stays there unless something washes it off.
Why the coast is different
Window makers set different care rules for homes near the sea. Trend Windows, for example, asks for aluminium windows within 10 km of breaking surf to be cleaned at least every month, and says products in sheltered spots need cleaning more often because salt builds up where rain can’t wash it away (Trend Windows). All of Cottesloe is well inside that distance.
Frame choices
uPVC frames don’t corrode. Aluminium frames can suit a coastal home too, but the powder coat, the hardware and the fixings all need to suit the site. Corrosion usually starts where fixings meet the frame, so ask what they are made of. We’ll tell you what each frame system is suited to before you choose.
Hardware and tracks
Double glazed panels are heavier than single glazed ones, so rollers, hinges and locks do more work. On a coastal home, ask for hardware made for coastal conditions and find out how it’s serviced.
Looking after them
A regular rinse with fresh water does more for coastal windows than anything else, especially under eaves and on the sheltered side of the house. We’ll give you the maker’s care instructions with your windows so the maintenance matches the warranty.
Windows are the weak point in most homes. Research reported in The Conversation found that up to 87% of a home’s heat gain on hot days comes through the windows, and about 40% of its heat loss on cold days goes out the same way (The Conversation).
Cottesloe looks west. The rooms with the ocean view are the same rooms that take the late sun, often through the biggest windows in the house.
What helps
A double glazed unit slows heat moving through the glass. Add a Low-E coating and more of the sun’s heat is reflected before it gets inside. On a west-facing living room that is the combination that makes the most difference late in the day.
The breeze isn’t enough on its own
Perth’s summer sea breeze cools the outdoors, but a closed room with the sun on the glass keeps heating up. Perth averages around 26 days a year at 35°C or more, and January and February are the hottest months.
Keeping the view
Nobody wants a grey ocean. There are clear and lightly tinted Low-E glasses that cut heat without dulling the view. We can bring samples so you can judge them against your own outlook.
Winter from the west
Most of Perth’s rain falls between May and September, and Cottesloe gets the weather first. Double glazing keeps the heat you pay for inside and cuts condensation on the inside pane on cold mornings.
The eastern side of Cottesloe is a transport corridor. Curtin Avenue, the Fremantle railway line and Stirling Highway run side by side through the suburb.
Main Roads WA counted an average of 24,280 vehicles each weekday on Curtin Avenue between Grant Street and Eric Street in June 2016, 1,416 of them heavy vehicles (Main Roads WA report, Town of Cottesloe). Five stations on the Fremantle line serve the suburb: Swanbourne, Grant Street, Cottesloe, Mosman Park and Victoria Street.
What works on noise
For traffic and train noise, what the glass is made of matters more than the fact that it’s double. WA’s road and rail noise guidelines give a benchmark: their quiet-house packages call for glazing such as 6mm-12mm-10mm double insulated glazing in bedrooms, where the two panes are different thicknesses (State Planning Policy 5.4 Guidelines). Laminated acoustic glass goes a step further.
Seals matter as much as glass
The same guidelines say the ratings depend on acoustic seals, with a seal on every edge of each window and a drop seal on doors. A gap lets sound straight through, so we’ll look at the seals as well as the glass.
Start with the bedrooms
If the budget won’t stretch to the whole house, begin with the bedrooms that face the corridor. We can quote those rooms on their own.
Samuele Caspani - Managing Director
Cottesloe has a lot of history for a small suburb, and some of its homes are protected. Check before you change the windows on a listed home.
The suburb is named after Thomas Fremantle, 1st Baron Cottesloe, and the Town of Cottesloe has been a local government since 1895. Wikipedia lists 430 heritage-listed places in the Town, 27 of them on the State Register (Wikipedia).
What the Town says
The Town of Cottesloe says places on its Heritage List need development approval for most development works, and a Heritage Impact Statement may be needed with the application (Town of Cottesloe). Being in the Local Heritage Survey alone gives no legal protection. The Town’s page doesn’t mention windows specifically, so if your home is on the Heritage List, ask the Town before you order.
Keeping the character
On an older home you may want to keep the frames. A double glazed unit retrofitted into the existing frame, or secondary glazing fitted behind it, can keep the look from the street while making the rooms inside quieter and more comfortable.
Frame condition first
Sound timber frames can often take new glass. Frames with rot, movement or failed joints usually can’t. We’ll give you a straight answer on what your frames can take.
Nearly a third of Cottesloe’s homes are apartments, townhouses or semi-detached. Double glazing works for them too, with a few extra steps.
Check with your strata company first
In many strata schemes the windows, or the way they look from outside, are covered by the by-laws or form part of the common property. Ask your strata company what needs approval before you order anything.
Secondary glazing leaves the outside alone
Where the outside of the building can’t change, secondary glazing fits a second pane inside the existing window. It doesn’t alter the facade and it’s effective against noise.
Balcony doors
Sliding doors onto a balcony take wind and sun and are often the biggest glass in the apartment. Glass in doors must be safety glass, and upper-level doors carry more wind load. We’ll specify each one for where it sits.
Access and timing
Upper floors, lifts and building rules all affect how the job runs. We’ll plan the installation around your building’s requirements.
Double glazing is priced opening by opening, so there’s no honest one-line figure. These are the things that move it.
Frame system
uPVC, aluminium and thermally broken aluminium perform differently and cost differently. On a coastal home, the finish and hardware you choose for salt air are part of the price.
Size and type of each opening
A small awning window and a four-panel stacker door are very different jobs. Large panes and stackers cost more because of the glass area, the hardware and the handling.
Glass make-up
Low-E, argon fill, laminated, toughened and acoustic glass each add cost and each does a different job. A bedroom facing Curtin Avenue and a living room facing the ocean may need different glass.
Replacement or retrofit
Taking out old frames and making good the opening is more work than fitting new glass into sound existing frames.
Access
Upper floors, apartments and tight side setbacks can need extra equipment or time.
How we’ll price it
We’ll measure each opening and give you a written, itemised quote so you can see where the money goes and change the specification room by room. For general glass replacement pricing, see our Glass Replacement Pricing page.
A good quote answers these before you have to ask. On a coastal home, the first two matter more than usual.
What are the frames and hardware suited to? Ask whether the finish, rollers, locks and fixings are meant for a site this close to the sea, and what care the warranty expects.
What glass is in each unit? Low-E or clear, argon or air, toughened or laminated, acoustic or standard, and the thickness of each pane.
What are the U-value and SHGC? These figures from the Window Energy Rating Scheme let you compare two quotes on performance, not just price.
Is it itemised? Each opening should be listed with its size, frame system and glass.
What’s included? Removal and disposal of the old windows, making good, and any access equipment for upper floors.
What does the warranty cover? Ask about frames, seals, glass, hardware and installation separately.
What’s the lead time? Double glazed units are made to measure, so ask how long manufacturing takes as well as installation.
We’ll answer every one of these in writing. Call 08 6150 8090 to arrange a measure.
Not every Cottesloe home needs new frames. The right option depends on the frames you have, the building you’re in and what the street sees.
Full replacement
New frames and new double glazed units. The best performance, and the chance to choose a frame system suited to the coast. It’s the right call when frames are failing or you’re renovating anyway.
Retrofit into existing frames
A double glazed unit fitted into your current frame, where the frame is deep and sound enough. It keeps the look of the house and costs less than replacement.
Secondary glazing
A second pane inside the existing window. Useful on heritage frames and in strata buildings where the outside can’t change, and good against noise.
How we’ll help you decide
We can inspect your frames and price each option so you can choose. See our Double Glazed Windows and Doors In Perth page for more, or our Window and Door Installation page if you’re replacing frames too. Nearby, we also cover Peppermint Grove, Claremont and Dalkeith.

They can be, if the finish, hardware and fixings suit a coastal site and the windows are rinsed regularly. uPVC frames don’t corrode. We’ll explain what each frame system is suited to before you choose.
It helps, and the right glass helps more. Panes of different thicknesses, laminated acoustic glass and good seals on every edge make the biggest difference to traffic and train noise.
If your home is on the Town’s Heritage List, most development works need development approval, and a Heritage Impact Statement may be required. The Town’s heritage page doesn’t mention windows specifically, so check with the Town before you order.
Usually, but check with your strata company first, as windows and the look of the building are often covered by the by-laws. Secondary glazing is an option where the outside can’t change.
It depends on the number and size of the openings, the frame system, the glass and access. We’ll measure each opening and give you a written, itemised quote so you can adjust the specification room by room.
It doesn’t have to. There are clear and lightly tinted Low-E options that reduce heat without greying the view. We can show you samples to judge in your own light.
Rinse the frames, tracks and hardware with fresh water regularly, especially in sheltered spots that rain doesn’t reach. Follow the maker’s care instructions, which we’ll give you with your windows.
Often, yes. If the frames are sound and deep enough, a double glazed unit can be retrofitted. If not, secondary glazing is another option. We’ll inspect them and tell you what suits.
They come from the Window Energy Rating Scheme. The U-value shows how much heat passes through the window and the SHGC shows how much of the sun’s heat gets in. Lower is better for both on a sunny west-facing room.
