Out along O’Hares Road and Wedderburn Road, the homes sit on big blocks with bushland reserves on more than one side, and Fire Trail SH 1.2 is a reminder of what surrounds them. Many were built in the 1980s and 1990s as brick veneer or brick and tile houses, often with the original single glazed frames still in place. If you are weighing up whether those windows have another few summers in them, this guide walks through the signs installers look for and the right time to act.
Key takeaways
- Age alone is not the trigger; draughts, sticking sashes, fogged glass and summer heat gain are the practical signs.
- The Australian Building Codes Board treats glazing as one of the largest influences on a home’s heating and cooling load, so window upgrades tend to pay off in comfort first.
- On bushland edge blocks, the glass and frame may need to meet bushfire construction requirements, so check before you order.
- Spring and autumn are the easiest seasons to schedule a full changeover, but a made to measure installer can work year round.
- Do the whole house in one go where the budget allows, or start with west facing and bedroom windows if staging it.
What are the clear signs a window has reached the end of its life?
A window is due for replacement when it no longer seals, no longer slides or locks cleanly, or when the glass itself has failed. These are the things we check first on a measure, and most homeowners can spot them without tools.
Run a hand around the frame on a windy afternoon. If you feel air moving at the corners, the seals have compressed or the frame has moved. Sticking sliders and sashes that drop on one side usually mean worn rollers or a frame that has racked slightly.
Look at the glass too. Condensation between panes in an older double glazed unit means the seal has gone, and chipped edges on single glazing point the same way. Newage supplies and installs new windows only, so the question becomes whether a new frame is the better long term answer, and in most of these cases it is.

Why do homes in this part of Wedderburn feel the heat more than others?
Many homes in this part of Wedderburn sit on open blocks with little shade on the western side, so the afternoon sun comes straight through the glass for hours. That is a different situation from a suburban street where a neighbour’s roofline gives some relief.
Modern aluminium windows made in Smeaton Grange with the right glass handle this far better than the thin frames of the 1980s. Moving to a low emissivity glass, or to double glazed windows on the worst facing rooms, keeps the inside temperature steadier and takes pressure off the air conditioner.
The Bureau of Meteorology’s records for western Sydney show summer days well into the high thirties are a regular feature, and window choice is one of the few things you can change about a brick veneer house that directly affects how that feels inside.
Does a bushland edge block change what windows you should choose?
Yes. Homes close to bushland and fire trails are often mapped as bushfire prone land, so the glass and frame may need to meet a particular bushfire construction level, and the dust and leaf litter out here are harder on seals and tracks.
Many homes in this part of the bushland edge were built before the current bushfire construction rules came in, so their windows were never assessed against them. When you replace them, a certifier or council may require the new windows to meet a bushfire attack level, which usually means toughened glass, metal framed screens on openable sashes and specific seals. Newage can quote to those requirements once the level is known, and the team will say plainly when an assessment is needed before anything is ordered.
Fully framed aluminium windows with good compression seals also cope better with dust and insects than older designs, and properly fitted mesh screens keep the breeze without the bugs on warm evenings near Mansfield Creek Reserve.

When does replacing windows need council or certifier approval in NSW?
In general, replacing a window with a new one of the same size in the same opening is treated as minor work in NSW and does not need a development application. Changing the size or position of an opening, altering a structural wall or working on a heritage listed property is different and may need approval from council or a private certifier.
Bushfire prone land adds another layer. Even a like for like change may need the new window to meet the bushfire construction requirements for that block, and a certifier may want evidence that it does. The NSW Government publishes guidance on which works are exempt, and it changes from time to time, so check the current version.
Newage advises on this during quoting. The team will tell you when something looks like it needs sign off and whether the opening can be kept as is to avoid the extra step. The business does not act as a certifier, but it has been through the process on many Macarthur homes since 2009.

Which season is the right time to book a full window changeover?
Spring and autumn are the most comfortable seasons to have openings exposed for a day or two, but there is no wrong month for a made to measure installer. What matters more is lead time and how many windows you are doing at once.
Every window is measured on site, made in the Smeaton Grange workshop, then installed by the same team, so allow several weeks between measure and install. If you want the house done before summer, measure in late winter or early spring. If you want it before winter, aim for late summer.
| Approach | Suits | Disruption | Things to weigh |
|---|---|---|---|
| Whole house in one visit | Homes where most frames are the same age | Two to three days | One measure, one install, consistent look throughout |
| Staged by elevation | Budget spread over a year or two | One to two days per stage | Start with west and north facing rooms; mixed frames for a while |
| Staged by room type | Bedrooms first for comfort and noise | Half a day to a day per stage | Quick gain where you sleep; living areas wait |
| Tied to a renovation | Kitchen or extension work already planned | Fits the builder’s program | Openings can be resized while walls are open |
How do you plan a window upgrade on an acreage home step by step?
The process is the same whether you do one window or twenty, and knowing the order helps you plan around it.
- Walk the house Note every window that draughts, sticks, fogs or faces the hot western sun.
- Check the land Find out whether the block is mapped as bushfire prone, because that shapes the glass and frame specification.
- Book a free measure An installer measures each opening, checks reveal depth and sill condition, and talks through frame styles and glass.
- Review the written quote Confirm sizes, opening types, glass, colour, screens and any bushfire requirements before approving.
- Fabrication Frames are made and glazed in the Smeaton Grange workshop, with an install date set once they are ready.
- Install and finish Old frames come out, new ones go in, flashings and seals are completed, and every sash and lock is checked.

What glass and frame choices suit an older brick veneer on a big block?
For a brick veneer home from the 1980s or 1990s, a fully framed aluminium window with a thermally efficient glass is usually the right balance of durability and comfort.
On glass, the choice comes down to exposure. North facing living areas with eave shade can often stay single glazed with a low emissivity coating. West facing bedrooms with no shade benefit from double glazing, which also takes the edge off noise if the house sits closer to Wedderburn Road. Toughened glass is required in some locations regardless, and on bushfire prone land it is often required across the board.
Newage aluminium windows for homes across Macarthur are made to measure, so odd sized openings in older houses are not a problem. For a companion read, see this checklist for windows on a bushland block.
Every Newage window is made in the Smeaton Grange workshop to suit your openings, including bushfire rated glass where the block needs it. Ask about options for your Wedderburn home.
What homeowners near O’Hares Road usually run into
Installers working on homes along O’Hares Road and the streets off Hillcrest Road and Bellbird Lane see a familiar pattern. The original frames are often a lightweight aluminium section with simple brush seals and single glass, and after decades of sun and dust the seals have flattened to almost nothing. Owners have lived with the draughts without noticing how much they have grown.
Ground movement is the next common thing. Many homes in this part of Wedderburn sit on clay soils that swell and shrink with the seasons, and the brickwork can move just enough to put a frame out of square, so a sash catches at one corner or a lock only lines up in winter. New frames are packed and fixed plumb in the opening, though the measure will note any cracking that a builder should look at separately.
Finally, bushfire requirements catch out homeowners who have ordered windows elsewhere without checking, which is why Newage asks about the land classification at the first conversation. You can read more about how the business works on its about page.

FAQ
How long do aluminium windows usually last before they need replacing?
Well made aluminium frames can last for decades, but the seals, rollers and glazing around them wear out much sooner. Most homeowners start noticing draughts, sticking sashes and failed seals somewhere between 25 and 40 years. When several windows show those signs at once, replacement is generally the sensible step rather than patching each one.
Do new windows on a Wedderburn acreage block need bushfire rated glass?
It depends on whether the block is mapped as bushfire prone land and what construction level applies to the house. Many properties near bushland reserves and fire trails in Wedderburn are affected. Newage asks about this at the first conversation and quotes to the required level once it is known, so the right glass and screens are ordered from the start.
Can I replace windows one room at a time?
Yes. Staging the work by elevation or by room type is common when the budget is spread over a year or two. West facing rooms and bedrooms usually come first for comfort. Each stage is measured and installed separately, and the frames are made to match so the finished house looks consistent once the last stage is done.
How much disruption is a full window changeover?
Less than most people expect. Each opening is typically exposed for only a few hours while the old frame comes out and the new one goes in, and a small crew works room by room. A whole house commonly takes two to three days. Furniture near windows needs to be moved back, and the team cleans up as it goes.
Will new windows fix cracks in my brickwork?
No. New frames are fixed plumb and square in the opening, which solves a sash that catches or a lock that does not line up, but any cracking in the brick itself is a separate matter for a builder. The installer will point out anything noticed during the measure so you can have it looked at before or after the window work.
