Innovative Home Improvements

Had Paul install a new skylight, and caulk all windows & other skylights. He lied that he caulked the other skylights, then he said they didn't need to be caulked, but did the caulking once I insisted. The new skylight leaked the first night, he claimed he wasn't finished, but he told me he was. He "fixed it", but it leaked even worse that night. He refuses to fix it because I paid $1,500 of the $1,800; which I paid right away, saying his warranty doesn't count until I pay in full, but the job is clearly not completed.
