The 8 yr old liner needed replaced from a leak under the steps so I called the original pool builder knowing he'd had problems when he originally built it and knew the size/shape of the liner and could order it from the previous owners info. Ordered it in Dec 09. Here comes January, a very wet January. We got 2.50 inches so far that month, and .50 inches of this was the day before the contractor calls and says I'm coming to put your liner in. I was surprized and said "YOU better be wearing boots as my back yard is FLOODED." He sent his crew and they pumped the remaining water out which was just a few inches below the steps where the leak was and took out the liner/smoothed the bottom with concrete and quickly put the new liner in. They left after they started filling the pool until they could come back and cut out the steps ect. The next morning early, my husband and I noticed large lumps and bumps around the edge of the pool. When the guys came they called the owner and I asked him if he wanted to see pics. He didn't but said to withhold money and he'd be back when the ground water was gone.The walls have caved in and hardened and I suspect the liner is ruined. It looked like the edges of Grand Canyon. It's June. I've tried calling him since April, he won't return calls. I reported him to BBB, Licensing Board, Attorney General and a demand letter from a lawyer. He only responded to BBB saying he's not responsible for the damage from the ground water. He lives in the vincinity, he knew how much it rained, he knew about the ground water problem from building the pool, he knew I lived 5 houses from a lake. How much is a contractor responsible for?
