I hired this company to do a refinish plaster work for my pool and install a salt system about 5 years ago. 2 weeks ago a drained my pool to wash it and replace the water, immediately I noticed cracks and hallow spots behind my plaster, I called the company to ask for them to come and inspect the plaster. Not only that they didn't want come to check the situation they also blamed me that I drained the pool and voided the warranty on the product. Joe the salesman's response was: "why did you drain the pool, you should not do it since it is voiding the warranty, put water back in your pool and it will push the air pockets back and you will not see the cracks....", (seriously???!!!). I called several other companies and they all told me that it is absolutely not true, if you drain to wash the pool and right away refill the pool you shouldn't have any problems. I ended up refinishing my pool and paid over $6000 since I had to remove about 25% of the plaster work that they did, I had huge air pockets and cracks behind the plaster work that they did since they didn't prep the pool properly before applying the "Florida Gem" product. I brought over 5 different professionals and they all said the exact same "bad prep work". On top of that I discovered the the salt system that they sold me was half the size that I needed for my pool. Stay away from this company.
