I had a 3 season porch changed to a 4 season porch. I had new drywall put up. The contractor says that they are done; however, I can still see the drywall tape enough that I could peel it off if I choose. the contractor says that painting will take care of this. Is that true? Also, he has put some caulking in the corners of the baseboards. Is that normal? Thank you in advance for answering my questions.
