We're thinking about making an offer on a house that has a 6 year old in ground pool. Pool details are as follows: Shotcrete, white plaster finish, free form shape and approx. 24K gallons. The pool is located in the Northeast so it's presently closed for the winter. For some reason the current owners choose not to open the pool this past summer (left the Loop-Loc installed) causing a large build up of algae. In addition to algae it appeared they didn't keep the water level below the tile line last winter and some of the tiles have popped off. My question is, if the pool needs an acid bath what should we expect to pay? As for the tile, what would it cost to remove and replace 6" the tile line?
Any help/advise would be greatly appreciated.
