How do you know when you need to re-plaster?
I twisted the arms of Gary Pools here in San Antonio and, while they wanted to send someone out, they did tell me that plastering starts at $5,000 and goes up. Is this true?
(The pool is perhaps 10 years old, and we have been maintaining a good chemical balance for the last six years, but I have no indication that it was maintained well prior to that.)
ETA: If we need it at all it's likely because of one 4 square inch part that looks bare.
