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.

Not every timber window needs the same solution. Some homes have sound internal timber reveals that may be retained, while others require new trim or a different finishing method. The most suitable approach is confirmed after the existing opening is assessed.

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.

01

Rotten or Soft Timber

Moisture exposure can cause timber to soften, split or deteriorate around sills, corners and joints.

02

Swollen or Warped Frames

Seasonal movement and ageing can make timber windows difficult to open, close or lock properly.

03

Frequent Painting

Peeling finishes and exposed timber may require repeated preparation and repainting to maintain appearance.

04

Outdated Window Layouts

Old configurations may provide limited ventilation, small opening sections or an appearance that no longer suits the renovation.

05

Ageing Glass and Hardware

Older glass, catches, hinges and stays can be upgraded as part of a complete aluminium replacement system.

06

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.

Existing Timber Reveal

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.

New Window Measurements

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.

Architrave and Internal Trim

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.

External Sealing

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 and Disposal

Removal of the old timber windows and disposal of removed materials can be included where stated in the written quotation.

Painting: Painting is generally not included unless specifically stated. New or modified timber trims may require painting after the aluminium windows are installed.

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.

Sliding

Aluminium Sliding Windows

Practical for bedrooms, living areas and locations where an outward-opening sash is not suitable.

View Sliding Windows →
Awning

Aluminium Awning Windows

Provide controlled ventilation and are commonly selected for bedrooms, kitchens, bathrooms and laundries.

View Awning Windows →
Fixed

Aluminium Fixed Windows

Ideal where natural light, a cleaner view or a larger uninterrupted glass area is the priority.

View Fixed Windows →
Casement

Aluminium Casement Windows

Side-hinged openings can provide strong ventilation and a crisp architectural appearance for suitable locations.

View Casement Windows →
Combination designs: Many timber replacements use a combination of fixed and opening panels, such as awning-over-fixed, fixed with sliding panels or casement with fixed glass.

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.

Colour availability: Final powder-coat colours depend on the selected aluminium system and supplier range. The chosen colour should be confirmed before manufacturing.

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 Homes

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.

Weatherboard Homes

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.
