We just bought our 1st house which includes a beautiful 30k gal gunite pool. I have the original pool contract which shows the pool was installed in 1993 by Anthony & Sylvan. The pool appears in perfectly fine shape, but I'm wondering how long we have left before needing to replace or heavily overhaul? As I've googled a bit, I'm seeing things saying we'll need to replaster every 5-6 yrs at $5-6k each time or that the pool only has a life of about 10-15 yrs. Is that true? The previous owners supplied pretty extensive records of changes & improvements to the house, and I don't see anything about major work being done to the pool beyond equipment replacement (new heater, filter & polaris within the last 10 yrs). Is it possible that the pool's never been replaster and if so is that a problem? Having the original contract, what sort of details should I look for to get a better idea? We're pool newbies!
