When it comes to windows and doors, quality products are only half the story. The other half? Proper installation. At Forever Green Windows, we understand that even the best uPVC double-glazed units won’t perform at their peak without precise, expert fitting. That’s why we now install what we make — every window and door is fitted by our installation team, so every project is completed to the highest standard.
Made in Gregory Hills: Supporting Local Quality
Every window and door supplied by Forever Green Windows is manufactured in our facility located in Gregory Hills, NSW. This local manufacturing not only allows us to maintain strict quality control but also helps us ensure faster turnaround times and a more personal, attentive customer experience. It also means we can respond quickly to queries or changes because we’re just around the corner.
Supplied and Installed by Forever Green
Forever Green Windows now supplies and installs everything we manufacture. We offer premium, double-glazed uPVC windows and doors to homeowners, builders, and renovators — and our installation team fits them. Because your windows are made and fitted by one company, they arrive on site exactly right for the opening, and you have a single point of contact from measure to final fit. If you’re a builder or owner builder with your own installer, supply only is still available.
Partial Installation Services for New Builds
For new home constructions, Forever Green Windows offers a flexible, partial installation service that allows builders to stay in control of the initial framework while ensuring expert attention is given to the most technical parts of the job.
Here’s how it works:
The builder installs the reveals, frames, and flashing on site. Once that step is complete, the Forever Green team steps in to complete the critical components:
- Glazing the windows and doors
- Fitting flyscreens
- Installing handles and functional hardware
This hybrid approach allows builders to maintain control of the build schedule while giving clients peace of mind that the most delicate and precise elements of the installation are handled by the window professionals themselves.
Why Proper Installation is Critical
The performance of double-glazed windows depends heavily on installation quality. Poor installation can lead to:
- Draughts and air leaks
- Condensation between glass panes
- Decreased energy efficiency
- Reduced acoustic insulation
- Operational issues with handles and locks
When installed correctly, however, uPVC double-glazed units provide:
- Exceptional thermal insulation
- Effective noise reduction
- Long-lasting performance
- Enhanced security
That’s why your Forever Green windows are installed by the team that made them — installation is never an afterthought.
