Recent Review: I have used Crystal Blue Pools services on multiple occasions and referred their service to clients, as well. ?Each time they have responded quickly, provided pricing that outmatches other competitors and handles the job all the way to the end with great professionalism. ?Our previous job by them about 4 months ago was a larger job with cement work of pouring colored cement for an approximate 700 sq ft patio, including the demolition and managing an existing sprinkler system. ?It could not have been handled better from beginning to end. ?The several other jobs I have asked their help with all went the same. ?A big thumbs up.
