We just had new vinyl siding (Certainteed) put on our old house. The corner cuts around the windows are not good fits. Should the builder need to put some sort of caulking in those corners to finish it off. If not only for asthetics, but is there any other reason to insist on this being done? Please let me know before I sign off on the job. Amazingly, it took them 4 weeks to do this simple under 2000 sq. foot home, so I'm not real confident in their workmanship. Please help!
