My contactor he is not responding to finish the Job or fix the issue on the work he has done. What should I do?

I hired a Contarctor, to demo old stucco, replace rotted studs, install new sheathing and apply new stucco for whole house (over 12000Sq.) with phase approach (1st front of the house, second right side of the house, 3rd left side of the house and last back of the house). He started first project early Nov, 2018 and completed in late Jul 2019 (took over 9months) to finish since he did not had a license to do residence work in my township. He also, did not took permit to do construction which was then later resolved. He supposes to start second project in early Aug, 2019, however he is not responding and in mean time I have water coming in my house where he completed stucco. Please let me know what should do so, he can come and fix his work? I’m not planning to hire him for rest of project now due to lack of his professionals and poor work.
