Melbourne Window Replacement
Custom Aluminium Replacement Windows for Melbourne Properties
Replacing old windows involves more than ordering a new frame at approximately the same size. The existing frame material, wall construction, internal trim, external finish, access, glass selection and required opening style should all be considered before the final product is confirmed.
1StopSupply supplies custom aluminium replacement windows made to suit the measured opening and intended use of each room. We work with homeowners, renovators, builders, property managers and commercial clients who need practical window replacement solutions.
Projects may include one window, several windows in one part of the property, or a complete whole-house window and door replacement.
Depending on the written quotation, our service may include site measurement, custom fabrication, delivery, removal of existing windows, installation, external sealing and selected internal trim.

Replacement Considerations
When Should Old Windows Be Replaced?
Some problems can be repaired by replacing rollers, locks, seals or individual glass panels. Complete replacement may be more suitable when the frame itself is damaged, outdated or no longer suitable.
Rotten Timber Frames
Timber windows may become soft, cracked, warped or difficult to maintain. Aluminium replacement can reduce ongoing frame maintenance and create a cleaner, more consistent appearance.
Rusted Steel Windows
Older steel windows may become rusted, difficult to operate or poorly sealed. The removal method depends on how the steel frame is connected to the surrounding wall.
Outdated Aluminium Windows
Older aluminium windows may have worn tracks, damaged frames, ineffective locks, poor seals or outdated glass and opening configurations.
Difficult Operation
Windows that no longer slide, wind, close or lock correctly can affect ventilation, everyday use and property security.
Water Entry or Gaps
Water entry may come from the window, surrounding sealant, flashing or adjacent building structure. The likely source should be considered before replacement proceeds.
Renovation or Glazing Upgrade
Replacement may be considered when updating the property exterior, matching existing windows or upgrading from single to double glazing.
Existing Window Frames
What Types of Windows Can We Replace?
Timber to Aluminium Window Replacement
Old timber windows can often be replaced with custom aluminium windows. The installation method depends on the existing frame, reveal, architrave, surrounding wall and condition of the opening.
The replacement can use sliding, awning, fixed, casement or combination window designs with suitable single or double glazing.
Timber to Aluminium Replacement →Steel to Aluminium Window Replacement
Older steel windows may be installed into brickwork, render or other surrounding finishes. A site inspection is normally required to understand the removal method and finishing requirements.
New aluminium systems can provide updated glass, opening sections, locks and frame colours.
Steel to Aluminium Replacement →Old Aluminium Window Replacement
Existing aluminium windows may be replaced when their frames, tracks, seals, locks or overall configuration are no longer suitable.
The new window can retain a similar arrangement or use a redesigned combination of fixed and opening sections.
Old Aluminium Replacement →Replacement Window Configurations
Replacement Window Styles
Different rooms and openings may require different configurations. A whole-house project does not necessarily need to use the same opening style for every window.
Sliding Windows
A practical option for bedrooms, living areas, rental properties and locations where an outward-opening sash is not suitable.
View Sliding Windows →Awning Windows
Awning windows open outward from the bottom and are commonly used where controlled ventilation is required.
View Awning Windows →Fixed Windows
Fixed windows are suitable where natural light, open views or a larger uninterrupted glass area is the main requirement.
View Fixed Windows →Casement Windows
Casement windows open from the side and can provide a wide opening and strong ventilation for suitable locations.
View Casement Windows →Glass Selection
Single, Double and Safety Glazing Options
Glass should be selected according to the room, window dimensions, location, safety requirements and intended performance.
Single Glazing
Single glazing can provide a practical and economical option for many standard window replacement projects.
Available choices may include clear toughened glass, laminated safety glass, frosted glass and selected tinted glass, depending on the system and project requirements.
Double Glazing
Double glazed units use two glass panes separated by a sealed air space. They may be selected for improved thermal performance, indoor comfort or a more substantial whole-home upgrade.
The frame, seals, opening style and installation should be considered together rather than treating the glass as the only part of the window system.
Laminated Safety Glass
Laminated glass may be suitable for selected safety, security or noise-control applications. The appropriate thickness and configuration depend on the window and project requirements.
Privacy and Tinted Glass
Frosted glass can be used in bathrooms, toilets, laundries and other privacy-sensitive areas. Selected tinted glass options may also be available for suitable applications.
Project Size
Individual Windows or Whole-House Replacement
Individual Window Replacement
A single damaged or outdated window may be replaced where the opening, location and surrounding conditions make replacement practical.
Multiple Window Replacement
Several windows can be replaced in bedrooms, living areas or one side of the property while leaving other suitable windows unchanged.
This can be useful for staged renovation projects or customers working within a specific budget.
Whole-House Window Replacement
A complete home project allows window layouts, frame colours, glass selections and opening styles to be planned together.
Property Construction
Window Replacement for Different Melbourne Homes
Brick and Brick Veneer Homes
Replacement may involve the existing reveal, internal architrave, external sealant and the connection between the original frame and surrounding structure.
Brick Veneer Window Replacement →Weatherboard Homes
Weatherboard replacement may require consideration of external boards, flashing, trims and the condition of surrounding timber.
Weatherboard Window Replacement →Older Melbourne Homes
Older properties may contain timber, steel and aluminium windows within the same building, as well as openings that have previously been altered.
