Our trade needs certifacations as much as any other trade does. Would you let an unliscensed electrician work on your house? How about a plumber without any insurance? I had a new roof put on my house last year and got several quotes. Did i go with the lowest? No, I went with the guy who showed me his insurance as part of his quote. The point is, we want to make as much as a plumber or an electrician but we do not want to do our homework! Do we need standards? You bet ya! If I were to change one thing it would mandate a certified installer. By demanding certifacation installers would be easier to track. If a customer chooses to hire someone for a reduced cash rate they would be nullifying their mill warrantee. If a certified installer becomes a hack he should lose his certifacation. I know this is idialistic, but it is the only way. There are still installers out there who do not seal seams or powerstretch their jobs. Is it fair that you should have to bid against these hacks? By having standards that have teeth and certifacations to back them up we can earn our fair dollar by doing things the correct way. LEVEL THE PLAYING FIELD PLEASE!
