The provider was involved from the beginning and was prompt with the bid and recommendations. We were able to come to terms and our early confidence in Carlos allowed us to move quickly. What we did not realize is that Diamond Pools subcontracted the entire deal out to a another group that did all of the work. We made it clear that communication and engagement were expected from DP and Carlos indicated he would provide regular updates so we would always know what was going on. We only saw Carlos when he picked up his first check and the last check. He never checked the work or the job. We became the contractors having to manage the work and call him to fix issues that he should've handled. When the determination was made that my sauna had to have $350 of additional modifications he never came by to handle or look at the situation. Fortunately the subs were capable and professional and we handled it. My property was not treated poorly but on multiple occasions we had to call Carlos to address trash, debris and clutter left on and around our property. The job was finished on time and our pool looks beautiful, but it had very little to do with Diamond Pools. We paid additional funds for solutions to problems they created. We paid for a leak detection and our pool still leaks. We knew this was going to be a problem when i asked Carlos if the leak was repaired now that the job was complete and water is pouring into the pool. Carlos looked at his subcontractor and me and said he did not know..." was it?". At this point we decided to cut ties with DP. We have gone to another service to handle this leak due to the lack of confidence in Diamond pools. We liked Carlos and he was extremely nice to us. Our pool is great and we receive compliments all the time. The bottom line is they are a good pool service company...but not a pool design company. If you choose to use DP you should ask for more from them and be very engaged in the process. In time they may improve and we wish Carlos well and success.
