I have seen post similar to this before but I can not find any solid information on prices. When searching on the internet I find that I should expect to pay between 4 and 7 dollars a sqft. to replaster a pool. I know this depends on a lot of things but I have gotten a couple of quotes that are far off from what I was expecting. My first quote was for $9500. And all it said was plastered with quartz plaster. My second quote was for $23,000. It was more detailed. They were charging $13,150 for 462 sqft of the pool and 64 sqft in the spa. $6,000 for 133 ft of tile replacement. And an additional $1,600 dollars because I have an infloor cleaning system. Plus 10.5% sales tax, which I didn't think was charge on services in Louisiana. My problem is I have no idea if any of these are fair. I have an issue with companies jacking up the prices on work they provide due to the neighborhood I live in. I was expecting somewhere around 6,000 to 7,000. Is this an unrealistic expectation?
