A Practical Home Upgrade
Give Old Timber Windows a Clean, Modern Aluminium Upgrade
Older timber windows can add character to a home, but years of weather exposure may leave them difficult to open, swollen, cracked, rotting or in need of repeated sanding and painting.
Improve Everyday Use
New aluminium windows can provide smoother operation, updated locks and practical opening configurations suited to each room. Instead of continuing to work around stiff sashes or ageing hardware, the replacement window is designed as a complete new system.
Refresh the Appearance of the Home
Slim, clean aluminium framing can give an older property a sharper and more consistent look. Frame colours can be coordinated across bedrooms, living areas, bathrooms and doors to create a more unified exterior.
Reduce Ongoing Frame Maintenance
Powder-coated aluminium does not require the same ongoing sanding and repainting commonly associated with exposed timber frames. Normal cleaning and hardware care are still recommended, but the frame finish is designed for easier long-term upkeep.
Upgrade the Glass at the Same Time
Timber-to-aluminium replacement is an opportunity to select new safety glass, privacy glass or suitable double glazing instead of simply replacing the frame with the same old glass arrangement.
Common Reasons to Replace
When Timber Windows Become More Trouble Than They Are Worth
Complete replacement may be worth considering when repeated repairs no longer solve the underlying frame, operation or appearance problems.
Rotten or Soft Timber
Moisture exposure can cause timber to soften, split or deteriorate around sills, corners and joints.
Swollen or Warped Frames
Seasonal movement and ageing can make timber windows difficult to open, close or lock properly.
Frequent Painting
Peeling finishes and exposed timber may require repeated preparation and repainting to maintain appearance.
Outdated Window Layouts
Old configurations may provide limited ventilation, small opening sections or an appearance that no longer suits the renovation.
Ageing Glass and Hardware
Older glass, catches, hinges and stays can be upgraded as part of a complete aluminium replacement system.
Whole-Home Renovation
Replacing mismatched timber windows can help create a consistent colour, frame profile and modern exterior across the property.
Designed for the Existing Opening
How Timber Windows Are Replaced with Aluminium
The new aluminium window is custom made from confirmed measurements. The installation method depends on the condition and construction of the existing timber frame, reveal, architrave and surrounding wall.
Where the internal timber reveal is sound, correctly positioned and suitable for the new window, it may be retained as part of the installation approach. Where it is damaged or unsuitable, a different trim or reveal solution may be required.
Final manufacturing dimensions are taken from the actual opening and selected installation method. The window is then made to suit the confirmed size, panel layout, glass and frame colour.
Internal architrave or trim can be discussed as part of the quotation. The required finish depends on how the original timber window is removed and the condition of the surrounding internal wall.
The new aluminium frame is sealed according to the agreed installation method and surrounding exterior finish. Brick, render and weatherboard homes can require different detailing.
Removal of the old timber windows and disposal of removed materials can be included where stated in the written quotation.
A Better-Finished Replacement
Why Aluminium Is a Strong Upgrade from Ageing Timber
A well-planned replacement combines the practical strength of aluminium with a layout and colour selected to suit the existing home.
Clean, Consistent Framing
Matching aluminium frames can bring together windows that were previously different ages, colours or styles, creating a more cohesive appearance across the property.
Practical Window Operation
New tracks, sashes, stays, locks and hardware are supplied as part of the selected window system, giving customers a complete replacement rather than another temporary repair.
Flexible Design Choices
Sliding, awning, fixed and casement sections can be combined to improve ventilation, light and everyday usability while retaining a coordinated frame finish.
Window Configurations
Choose the Right Aluminium Window Style for Each Room
The replacement does not have to copy the original timber window exactly. Subject to the opening and project requirements, the new configuration can be redesigned to improve ventilation, light and convenience.
Aluminium Sliding Windows
Practical for bedrooms, living areas and locations where an outward-opening sash is not suitable.
View Sliding Windows →Aluminium Awning Windows
Provide controlled ventilation and are commonly selected for bedrooms, kitchens, bathrooms and laundries.
View Awning Windows →Aluminium Fixed Windows
Ideal where natural light, a cleaner view or a larger uninterrupted glass area is the priority.
View Fixed Windows →Aluminium Casement Windows
Side-hinged openings can provide strong ventilation and a crisp architectural appearance for suitable locations.
View Casement Windows →Frame Colour and Home Appearance
Create a More Unified Look Across the Property
Replacing old timber windows is also an opportunity to coordinate the frame colour with brickwork, weatherboards, roofing, gutters, doors and interior finishes.
Black
A strong contemporary choice that creates clear definition against many brick, render and cladding finishes.
White
A clean, versatile finish that can suit light interiors, rendered homes and many traditional renovations.
Monument
A popular deep neutral often coordinated with modern roofs, gutters, garage doors and exterior details.
Woodland Grey
A softer natural grey-green tone that can complement weatherboard, brick and landscaped surroundings.
Glass Upgrade Options
Replace Old Single Glass or Upgrade to Double Glazing
The new aluminium frame can be specified with suitable single glazing or double glazing, allowing the glass choice to be considered at the same time as the timber-frame replacement.
Single Glazed Replacement Windows
Single glazing can provide a practical option for standard replacement projects. Clear toughened, laminated safety, frosted and selected tinted glass may be available depending on the window and application.
- Practical option for many standard projects
- Safety and privacy glass choices available
- Suitable for different room requirements
Double Glazed Aluminium Windows
Double glazing can be selected for suitable frames and openings where customers want a more substantial upgrade in thermal performance and indoor comfort.
- Two glass panes with a sealed air space
- Frame, seals and glass designed as one system
- Can be planned for selected rooms or the full home
Different Home Constructions
Timber Window Replacement in Brick and Weatherboard Homes
The surrounding building construction affects how the old timber window is removed and how the new aluminium frame, internal trim and external sealing are completed.
Brick and Brick Veneer Properties
The installation may involve the existing timber reveal, internal architrave, brick opening and external sealant. The goal is to install the new frame neatly while limiting unnecessary disturbance to surrounding finishes.
Brick Veneer Window Replacement →Weatherboard Properties
Weatherboard replacement may require consideration of external boards, flashing, trims and the condition of surrounding timber. The installation approach is confirmed according to the existing exterior detail.

Coordinate Timber Window Replacement Across the Property
Customers can replace one priority window, complete one section of the house, or plan a full-home upgrade with matching aluminium frame colours and room-specific window designs.
Priority Windows First
Start with the windows that are most damaged, difficult to use or exposed to weather, then continue in later stages if required.
Match New Windows and Doors
Coordinate aluminium windows with sliding or hinged doors, flyscreens and selected security screens for a more complete exterior upgrade.
Plan a Whole-House Upgrade
Choose one frame colour while tailoring the opening style and glass to bedrooms, bathrooms, kitchens and living spaces.
