Recently went union 2 years ago after residential work. It's a whole new world, hoping to learn more. More importantly, hoping to some-day help one of you fine installers figure out a problem. And I may have an issue of my own from time to time, and would appreciate professional courtesy, as it will be given from my end as well.. A g'day to you all...Go Blue, Go Lions, and drink a beer for me (if you need a reason)
