I was very pleased with the installation and careful attention that Suffolk Liner paid to the liner installation. We had a Merlin pool liner installed. They were very clear about how to refill the pool after installation. Because we had the liner replaced in late September, we chose not to fill the pool up to the skimmers, so will not know if there are any problems until next summer when we open and fill the pool to above the skimmers and the pool light. I am pleased with the quality of the Merlin liner, the wall foam insulation, and the liner lock around the entire pool The pool looks great.
