been in my house for a few months. we have an inground SW pool that was recently refinished, however the tiling along the top apparently was not. the tile runs from under the pool deck topping to about 6" down, about half and half with the water line. I have seen quite a few cracks running parallel with the deck along the top of the tile and also some areas of grout missing. I assume I need to get this corrected. Do I need to have someone come in and re-do all the tile and grout...or is there a product that I could use to replace some holes and fill/waterproof the cracks? the cracks are about wide enough to insert a house key into
