There is no getting around it, old windows will eventually need replacing. Single-pane or ageing windows offer poor sound insulation, letting outside noise filter freely into your home. They also do little to protect against Australia’s extremes of heat and cold.
Over time, frames can warp or become damaged, making windows difficult to open, close, or lock correctly, a genuine safety risk in an emergency. Seals deteriorate, creating drafts and cold spots as air travels freely in and out. In double or triple glazed windows, condensation forming between panes is a clear sign that the seal has failed and the unit needs replacing.
One of the most important considerations when weighing up window replacement is not the upfront cost of new windows, but the ongoing savings they generate. Modern, well-sealed windows mean your heating and cooling systems work far less to maintain a comfortable temperature, and that difference shows up on your energy bills every month.

The Timeline: From Initial Quote to Installation Day
Energy efficient windows are one of the most effective ways to reduce living costs in Australian homes. Ultimate Windows specialises in uPVC double glazed windows, keeping us at the forefront of the glazing industry in Victoria, New South Wales, and the ACT.
Once our team has visited your home and assessed your needs, you will receive your quote. It is not possible to give a generic timeline for every job because every order is different. Lead time depends on the complexity of your order and current production demand.
Key factors that influence the timeline include:
- Manufacturing time: Because we manufacture locally in Wodonga, our turnaround times are generally faster than companies relying on imported products. Standard designs move through production quicker than custom-configured windows.
- Order complexity: Larger orders, unique sizing, or specialised window types such as tilt and turn windows or triple glazed windows will naturally require more production time.
- Seasonal demand: High-demand periods may extend the wait for an installation date. We keep you informed throughout the entire process so you are never left wondering where your order is up to.
- Installation duration: The time spent on-site varies depending on the number of windows, their size, and the complexity of the job.
Throughout the entire process, our team communicates clearly and keeps you updated at every stage.
How to Prepare Your Home for the Installation Crew
A little preparation before our team arrives goes a long way toward protecting your belongings and helping the job run smoothly. The area around each window, both inside and outside, needs to be fully accessible so our crew can work safely and efficiently on both sides of each opening.
Inside the Home
- Remove curtains, blinds, and any window furnishings.
- Move furniture and valuables away from the window areas.
- Take down wall hangings or artwork near windows, as vibrations during removal can cause them to fall.
- Cover floors and remaining furniture with old sheets or plastic sheeting to protect against dust and debris.
- Disable any window or door security alarms to prevent false triggers during installation.
Outside the Home
- Clear away plant pots, outdoor furniture, and any other obstructions around the window openings.
- Trim back any plants or bushes that may obstruct access to the work area.
- If possible, ensure there is adequate parking nearby to make loading and unloading easier for our crew.
On the Day
- Be prepared for some noise and dust during removal and installation.
- If you work from home, consider making alternative arrangements for the day.
- Plan for children and pets to remain in a separate part of the home, or away from the property entirely, for their safety and the crew’s ability to work freely.
Installation Day: The Step-by-Step Process
Before work begins, take the opportunity to ask our team any last-minute questions you may have. Our installers are experienced professionals who are happy to walk you through what to expect.
The professional window installation process follows a clear sequence:
- Remove the old window and frame carefully, ensuring the surrounding wall structure is not damaged in the process.
- Clean and prepare the opening by removing old sealant, foam, and debris.
- Check the opening is level and square, making any adjustments needed before the new window is positioned.
- Apply waterproof flashing tape to the perimeter of the opening.
- Position and level the new window frame, securing it with appropriate fixings.
- Seal the frame both internally and externally to complete the installation.
The Critical Professional Difference: Flashing, Sealing and Compliance
What separates a professionally installed window from a DIY job comes down to three non-negotiable elements: flashing, sealing, and compliance. Each plays a distinct role in the long-term performance and legality of your new windows.
Flashing
Flashing is a waterproof barrier installed around the window frame that physically redirects water away from the opening and prevents it from entering the wall cavity. It is a mandatory requirement under the National Construction Code (NCC) and represents the primary line of defence against water ingress and the structural damage that follows.
Sealing
Sealing refers to filling the gaps between the window frame and the surrounding wall to prevent air and water from penetrating the installation. Proper sealing provides secondary weather protection and is critical for achieving the thermal and acoustic performance that quality windows are designed to deliver. Poor sealing is one of the leading causes of condensation, drafts, and premature window failure.
Compliance
All replacement windows in Australia must comply with Australian Standard AS 2047 and the NCC. Professional installers are responsible for ensuring this compliance and, where required, providing performance labels or compliance certificates. This protects you from liability and ensures your home insurance remains valid.
| Element | What It Does | Why It Matters |
|---|---|---|
| Flashing | Redirects water away from the opening | Primary defence against water damage and wall rot |
| Sealing | Closes gaps between frame and wall | Prevents air leaks, drafts, and condensation |
| Compliance | Meets AS 2047 and NCC requirements | Protects your legal standing and home insurance |
The Final Walkthrough, Clean-Up and Warranty
When the installation is complete, our team conducts a thorough clean-up and removes all debris, off-cuts, and packaging from your property. We leave your home tidy so all you need to do is clean the new windows, frames, and sills, then sit back and enjoy the difference.
Before our crew leaves, they will walk you through the new windows, demonstrate how they operate, and answer any questions you have about maintenance or care. You can find further guidance in our window maintenance resources.
Every installation carried out by Ultimate Windows is backed by a comprehensive warranty that goes well beyond the industry standard of five years. We are confident enough in the quality of our energy efficient uPVC windows and doors to offer extended cover, because we know you are unlikely to need it.

Frequently Asked Questions
How long does a professional window installation take in Australia?
The duration of a professional window installation depends on the number of windows, their size, and the complexity of the job. A single window typically takes a few hours. A full home replacement can take one to several days. Custom-manufactured windows, such as those produced by Ultimate Windows in Wodonga, may have a production lead time of several weeks before installation day.
What is the difference between flashing and sealing in window installation?
Flashing is a waterproof membrane installed around the window frame that redirects water away from the wall cavity, it is the primary barrier against water ingress. Sealing refers to filling the gaps between the frame and the surrounding wall to prevent air and water movement. Both are required for a compliant, weatherproof installation under the NCC.
Do I need to be home during window installation?
It is generally recommended that a responsible adult be present at the property during installation, at least at the start and end of the job. This allows you to ask questions, confirm access to all areas, and complete the final walkthrough with the installation team once the work is finished.
Are professionally installed windows covered by a warranty in Australia?
Yes. Reputable window companies provide a warranty covering both the product and the installation workmanship. Ultimate Windows offers a warranty that exceeds the Australian Window Association’s recommended five-year minimum, giving homeowners greater long-term protection and peace of mind.
