Our double glazing installations are the perfect choice to regulate the temperature of your Williamstown home. In the winter, warm air will be trapped more effectively in your home, cutting down the need for central heating and keeping your home cosy. In the summer heat will be reflected out from the home, keeping you cooler and more comfortable.
Our uPVC products offer incredible energy efficiency, reaching U-values as low as 1.0 W/m2K. Our windows and doors will effortlessly improve the performance of your home.
uPVC is also incredibly sustainable and can be recycled up to 10 times! To make an environmentally friendly choice to elevate your home, our uPVC products are the way to go.
When choosing new doors and windows, security is a top priority for Williamstown residents. Our doors and windows are specially designed to offer increased protection. Our windows have six-point locking mechanisms, and our doors have nine-point locking mechanisms. All of our uPVC home improvement products meet UK police security standards.
Enjoy the benefits of our uPVC double glazing products beyond the enhanced performance and efficiency. uPVC is very low maintenance, only needing a wipe with a cloth now and then to keep them looking factory-fresh. They won’t fade or discolour with UV exposure, so no need for touch-ups.
Our double glazed windows and doors will also elevate the aesthetics of your Williamstown property. Our stunning profiles will become an eye-catching feature of your home, elevating your home’s kerb appeal and market value.
Our products are specially designed with Australia’s harsh climate in mind. They are constructed to be resistant to damage from sand, erosion, UV exposure, and more.

We have had several window installations done by Ecostar over a period of approximately 3 years. Their service had been excellent and any problems encountered have been courteously, promptly and professionally resolved. We are delighted with the work done and are very happy with our purchase.

Love my new windows. Great service from start to finish. Made such a difference to keeping our old house warmer and keeping street noise out. Initially my husband was a bit sceptical, but he is now a fan. And we were still able to have the lead light copied to match my old windows. Which no other company was prepared to do.
Kim Gardner
Ecostar were professional from their first sales visit. The salesman was promptly on time, easy to deal with and gave us options when we couldn’t decide. We installed 4 sliding doors, replacing our 1980s windows.
The double glazed doors are more than we expected, the locking mechanism makes me feel safe, the double glazed glass makes a huge difference in both winter and summer, and also cuts the traffic noise down. The installers were lovely and put them in place with no mess to clean up. I can’t wait to get the rest of the house done.
Jerry Balej
Ecostar’s installers were prompt and efficient. Quality of product and workmanship is excellent. During the colder months we were pleased at how warm it was inside without heating. Also it was so much quieter indoors as outside road noise has been significantly reduced that you need to listen carefully to hear any of it. All in all my wife and I are very pleased with our choice in having Ecostar Double Glazing replace our windows and doors.
Kristen Ingram
We were so happy with our first set of windows that we completed the job and had the remainder of the house upgraded. Noise is down significantly and the heater and coolers are not working as hard to keep the temperature comfortable. The windows themselves are terrific, as is the service afterwards when they move a little out of alignment with the house. Just a tweak and they’re all good again. Sturdy, easy to use and well worth the investment.
Georgina Last
The team at Ecostar were amazing from start to finish. Professional and punctual from the moment of engagement, quotation, surveying, installation and post-installation service. Extremely friendly and high quality team and the product is definitely worth the investment.
Jon Hill
The windows and doors are great, the team who fitted them were excellent, they kept me informed throughout the install and patiently answered my many questions. Everything done to a very high standard. I would recommend Ecostar Double Glazing.
