Des Irwin

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.

Angela Stante

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.

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.

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.
