Purchased doors and windows through GEM Castle Hill branch. Worst quality and service I have seen in 20 years of renovating homes. Doors don't close, scratched flimsy aluminum, wrong doors for frame and 4 month delivery after paying in full and being told 6 weeks. Don't use them and I'm sure any positive reviews are fake. Google more reviews and you will see many unhappy customers. I wish I had done this prior to throwing thousands of dollars away. Consumer Fair Trading complaint for sure. read more
