I'm going to tell the Contractor that there is NO WAY he should send just ONE guy to do so much work. This guy is prepping, scraping and "cleaning". Because he is doing all three, I do see a bit of sloppiness in Prep and cleaning. He's a bit absent minded. AFTER he swept the garage, I lowered the door only to find popcorn goo on the door track and spring. I said EFF it and just grabbed my garden hose and washed everything. Including the wall panels. It's so hot outside it will dry in 30-40 minutes. Super nice kid and VERY Polite. But he is too inexperienced to be working alone.
