We had to get our pool replastered last year. We went with a company called All American Pool and Spas based out of Redlands. I wasn't certain how they were going to do so I first checked out there website and then I checked up on them at places like the BBB. When I requested my free quote, I spoke with the contractor about this exact potential issue. He said this: If something goes wrong He'll fix it without an issue. The problem," he continued, "is that the cost of defending himself in court is higher than the cost of replastering and if he were to lose in court, he would still have to pay for the fix." Whether or not it was the actual truth or not, I do not know but it was enough for me to go with his company. The best part is that the pool came out exactly as it was intended.
