Thanks everyone for your advice. That thread is insane, WOW! That was quite the redo. My husband took a few hours today power washing the rough area in more detail than before. Hopefully that will buy us a little time and get us through the rest of the season, especially if I keep the FC levels higher. I can see now why the previous owners said the pool can with the home sale "as is".
What should I know when shopping for contractors to do a resurfacing? Is the average cost in the $8,000-$9,000 range? Anything that should put up a red flag when talking to contractors? What are some options we should know about? I've seen different names of products, but I don't really know what any of that is.
