Melbourne's replacement window and door specialists
Northstar supplies and installs premium double glazed uPVC windows and doors throughout Melbourne — specialising in replacement, and taking on new builds and renovations.
Windows and doors, considered properly.
Northstar Double Glazing is a Melbourne-based double glazing supplier and installer. Our speciality is replacement: taking out tired aluminium or timber windows and doors in occupied homes, and fitting high-performance double glazed uPVC in their place without leaving a mess behind. We also work on new builds, renovations and custom openings that need something specific.
Every project is measured, specified and quoted individually — no catalogue orders, no guesswork. All windows, doors and glass are manufactured to the relevant Australian Standards, and the work is backed by a 10 year warranty on frames, glass and workmanship.

The Northstar way
Four principles every project runs on.
How we approach a window and door package, from the first conversation through to installation.
Principle 01
Specified, not guessed
Every window and door package is specified around the home in front of us — the openings, the orientation and how the rooms are used.
Principle 02
Measured on site
Openings are measured and confirmed in person before anything is ordered, so what arrives is what the home actually needs.
Principle 03
Premium uPVC only
Northstar supplies premium double glazed uPVC window and door systems. Systems, glazing and hardware are specified per opening rather than sold as a catalogue item.
Principle 04
Clear written quotes
You receive a clear written quotation covering supply and installation before any work is scheduled.

Google reviews
Five stars from Melbourne homeowners.
Every review below was posted publicly on Google by a Northstar client.
“Really impressed with the quality of the windows and the overall finish. The tradies were professional, tidy and looked after my home throughout the installation. Noticed a huge difference already!”
“I got my front door replaced by Northstar Double Glazing. Great service and will be back for the rest of the house.”
“Had my whole house of windows and doors replaced by Northstar Double Glazing. It has made a significant difference in keeping the heating in the home during winter and as I live on a busy main road the noise reduction we get from the new windows is remarkable (I now have a peaceful sleep). From sales to the installation the process was straight forward and all of the installation team are true professionals. The quality of the finishing is A grade. Highly recommend using Northstar if you want a premium product at a good price.”
