Let these idiots into your house at your own risk.
I had Gregs Glass measure (ha!) and replace some old glass windows. The installer that turned up for the first job of the day (@ 11am). One window pane was measured too big so it had to go back, the main panel left only 1mm gap around the frame so the beading didn't fit, he then decided to silicon the beading to the glass... Clearly a professional, he then continued to chip the wall paintwork and scratch the alloy frames with his tools as he went. The black handprints that couldn't be removed were a great touch.
The mess, packing and alloy metal bits was left behind for me to trip over and clean up. To cap it off , the installer removed and then lost the alarm magnet that was attached to one of the old glass panels, so I was thrilled when I could no longer set my house alarm. It was all resolved with a quick call to the cretin in their showroom who accused me of removing the alarm component myself before the glass was removed by them and that actually they never work on houses that have alarm systems! The install bill was extortionate for a few pieces of glass and the call out to the security company to fix the alarm was a further $200.
It was such a great job that when an actual proper professional Glass company in Rockingham installed my shower they were in disbelief when I showed them the quality work done by Gregs Glass, so much so that they said I should have asked for my money back...
Don't let these clowns into your home! (unless of course you want to get it done properly afterwards by real glaziers.)
