You are caught in the "Pool Company Nightmare." You should have gotten references from others who have used this company...actually, it isn't a company, but a contractor who subs out all the work to this or that party...Digging is one person, rebar is another person, gunnite is another person, electric is another person, tile is another person, plaster is another person..ladders,etc is another person...you get the idea. Call a Pool plasterer, an electrician, and a tile man...get estimates for completion immediately, when can they do it, etc. Get price on tile...must be installed before the plaster (use epoxy thin set...spec that in the tile contract). Once you have this in place, call the pool company and tell them you are canceling the contract with them for Non-performance. I hope you have taken pics and dated them along the way, kept a journal of all calls made and promises made and broken. If not, reconstruct on right now...you will need it when the pool contractor sues you..he won't win if you can produce the journal and pics of how he has left the place. What is happening to you is: The contractor is spending money faster than it is coming in. His subs will not work for him unless they are paid up front, for he has not paid them in a timely manner in the past. He must sell new jobs to get money to finish each phase of your job, and he can't get new money until he has started the new job..he is doing a juggling act, still spending more than he takes in between living and paying subs. He is a very poor contractor !! Don't even think there is a guarantee on the job! He will not be able to afford to fix anything that is wrong. And the "he" could well be a "she." I have seen both sexes play this game in all phases of contracting, but it is really pronounced in the pool game. Don't even think about given them one more cent until the job is finished, regardless of what the contract says. Call the company after you have talked to all these different subs..you can act as your own contractor at this point! Tell them you are cancelling the contract as of ...give a 4 day period. Tell them that once you have a new company on the job, they will not be allowed access to the site, period. See if that doesn't do some good....probably will get you a new set of lies...too wet, too dry, too hot, too cold, too anything but too much labor...what he is really saying is ...it costs too much for me to fininsh. Good luck
