Installing windows in a new home or extension is different from replacing old ones. There are no existing frames to remove, but there is a build program to keep, other trades waiting on lock-up and energy requirements to meet. Our new window installations are planned with all of that in mind.
We fit aluminium windows, sliding and stacking doors and fixed glazing into new timber or steel frames, then flash and seal each opening to suit the cladding. We check sizes against the plans and the frame before installation, so problems are found early rather than after the plasterers arrive.
The service suits builders, owner-builders, knock-down rebuilds, extensions and second-storey additions.
In short: Hustle Installations installs windows and doors in new homes, extensions and rebuilds for builders and homeowners. Cost depends on the number and size of windows, glass type, storey height and cladding. We aim to respond to enquiries within one business day, and quotes from plans are free.
On a new build, windows are one of the key steps toward lock-up. Once they are in, the home can be closed against the weather, insulation and plaster can go in, and internal trades can start. If windows arrive late, are fitted out of square or are left without proper flashing, the delay or defect flows through to every trade that follows and can show up later as leaks or sticking sashes.
We work from your plans and window schedule, confirm opening sizes once the frame is standing, and book installation to suit the builder’s program. Each window is packed, fixed and flashed to suit brick veneer, weatherboard, lightweight cladding or render. You can read more about our general approach on our window installations page. For new homes, we also coordinate with the glazing and energy specifications so the windows that go in match what was assessed.
Many defects in new homes trace back to window installation. These are the issues we see most often:
Frames not matching the plans. Openings built slightly out of size or square mean windows do not sit correctly. We check every opening before fitting.
Missing or poor flashing. Sill and head flashings that are left out or lapped the wrong way can let water into the wall cavity. We flash each opening to suit the cladding.
Wrong glass for the energy rating. Installing windows that differ from those in the energy assessment can cause compliance problems. We match glass and frames to the documents.
Rushed installation. Windows squeezed in between trades without proper packing often stick or leak later. We schedule enough time to do the job properly.
We tailor each installation to the home, the cladding and the program.
New build installation pricing reflects the scope of windows and the conditions on site:

We fit around the builder’s program rather than the other way round. That means confirming dates early, checking the frame before we arrive and finishing each window so it is ready for the trades that follow.
Our new build installations follow four steps:

Fully licensed and insured window and door specialists you can trust.
The highest quality products and materials at very reasonable prices.
We deliver the results you want on budget and on time, every single time.
Windows in new homes generally need to comply with AS 2047, the Australian Standard for windows and external glazed doors, which covers structural performance, water resistance and air infiltration. Glass in doors, low windows, bathrooms and other areas of risk must be selected in line with AS 1288. For homes in bushfire-prone areas, windows and glazing need to suit the site’s BAL rating under AS 3959 where required.
Energy efficiency is the other big factor. Under the National Construction Code, new homes need to meet minimum energy performance, and windows have a major influence on the result. We install the frames and glass specified in your energy assessment and seal each opening carefully to reduce air leakage. Building in Melbourne?

Builders tell us their main frustrations with window installers are missed dates, rushed work and defects that only show up after handover. Owner-builders often struggle to coordinate the window order, delivery and installation with everything else on site. Homeowners building their first home worry about leaks and draughts in a brand-new house.
We address these concerns by planning installation alongside the build program, checking frames before we fit and taking care with flashing and sealing. We communicate clearly with the builder or owner, so everyone knows when windows will go in and when the next trades can start.
What sets us apart:
Installation dates are set around your build so lock-up stays on track.
We measure the standing frame before fitting to catch size and square issues.
Every opening is flashed and sealed to suit the cladding type.
We fit the glass and frames specified in your energy assessment.
Builders and owners are kept updated before, during and after installation.
We aim to respond to enquiries within one business day.
Tell us what you need, where the project is located, and what outcome you want. We ask the right questions, review the scope, and provide a clear quote with no obligation.
We inspect access, openings, levels, existing frames, surrounding finishes, and any site-specific requirements. Accurate measurement helps prevent delays, gaps, and unnecessary rework.
We confirm the installation approach, materials, scheduling, and finish expectations. For Melbourne projects, we can also discuss thermal performance, double glazing, weather sealing, and BAL rating considerations where required or relevant.
Our team installs with care, precision, and safety. We focus on alignment, fixing, glazing, sealing, operation, and clean presentation.
Before we leave, we check the installation, clean the work area, and walk through the finished result. You get a tidy site and a result built to perform.
New window installations involve fitting windows and glazed doors into a new home, extension or rebuild, usually at frame stage before cladding and lining are complete. Unlike replacement work, there are no old frames to remove, but the installation must fit the build program, suit the cladding and match the energy specification for the home.
Windows are usually installed once the frame is up and the roof is on, as part of reaching lock-up. Timing depends on the cladding type and the builder's program. We recommend booking new window installations early so dates can be confirmed once the frame is ready, avoiding delays for later trades.
Yes. We install windows for builders on new homes, townhouses and extensions, and for owner-builders managing their own projects. We can price from plans, check openings on site and schedule installation around other trades. Owner-builders often appreciate our guidance on flashing and sequencing.
Yes. Many builders order windows through their own supplier and need a reliable team to fit them. We can install supplied windows, provided they suit the openings and arrive complete with the right components. We can also supply and install if you prefer one team to handle both.
Windows have a big influence on a home's energy rating. The glass and frames installed need to match the performance values used in the energy assessment, and careful sealing reduces air leakage. We install new windows to the specified glazing so the finished home reflects what was assessed.
Windows generally need to comply with AS 2047 for windows and external glazed doors, and safety glass must be used where AS 1288 requires it. In bushfire-prone areas, windows must suit the site's BAL rating under AS 3959 where required. Our new window installations are carried out with these requirements in mind.
A typical single-storey home usually takes one to a few days, depending on the number and size of windows and doors. Double-storey homes and large stacking doors can take longer. We confirm the expected timeframe with your quote so the builder can plan the following trades.
Yes. We remove packaging, offcuts and protective materials from our work areas and leave the site tidy for the next trade. Protective films on frames are usually left on until the builder is ready, to protect the finish during the rest of construction.
Yes. Large sliding and stacking doors are common in new homes and extensions. They are heavy and need careful handling, level sills and precise adjustment to run smoothly. We plan the installation so these doors are fitted correctly and protected until handover.
