I'm rehabbing a house in Phoenix Arizona that has a large diving pool. I just received a quote to renovate the pool for at least $25,000, he said it could go more. I just don't understand how replumbing and resurfacing this pool costs more than 15k. All I want is the pool functional again so I can advertise the house with pool. Anyone have recommendations or anyone want to have a go and provide a quote? Thank you so much!
