I just had my pool contractor finish an install of a new vinyl liner on my in ground pool today (was supposed to be done April 16th, whole other story to why it took so long). He had to come back on 4 different occasions to try to get 3 of the corners set into the track and after doing so I'm really not happy with the way it looks. I also have many wrinkles on and around my steps that he said he can do nothing about, the liner also has so much slack at the stair wall that I can almost pinch my fingers around it in the middle of the wall. I would love to post some pictures (words won't give you the best feel for my concerns) of all this to get some honest opinions of his work as I still have to pay off half the balance of what I own and my gut is telling me i shouldn't do that quite yet. He has admitted to filling the pool to fast and the "factory" measurements for my pool may be off because the pool is over 30 years old and has settled.
