Just bought the house and this is the first time I've owned a pool. Pool had been negelected because the house was a foreclosure. Plaster is stained from algae and leaves in the pool. Plus it is about 10 years old. My wife would like to have it redone with pebble tech but the quote we got was almost $8000 to do it so thats out. What would be a FAIR price for just having it redone in regular white plaster? And should I even try to see if an Acid wash will work? Pool cleaner quoted me $450 for that but I'm not sure if it will work?
