I have an approximately 30,000 gallon custom-shape pool and a 7-foot circular spa at a home I'm in the process of purchasing that needs replastering and tile replacement. It's the original plaster from 1978 and oddly looks mostly OK except for some bubbling and peeling in the deep end. The seller obtained a bid from an Anderson Pool & Spa in Pomona to chip and replaster for $4,000 and replace the tile for $2,000. That seems more than reasonable to me, but I know nothing about this outfit. I want to get a bid from at least another company or two. Does anybody have recommendations for the Los Angeles-Pomona area?
