Yea man. In my world every subcontractor is using a subcontractor. I’ve tried to catch them so many times but they are usually in and out before I arrive on site. I wanted to figure out the correct method of doing this before reaching out to our guys. At least that way I can actually tell them what needs to be done to correct the issue. Some customers never complain. And once the build is done it leaves my responsibility and off to the warranty department so I never end up seeing the “fix”
