Imperial Pools Inc. technicians were excellent! This was my first time using them. A friend referred me to them. I had them do my pool opening for the season. The workers were knowledgeable and professional. They showed up on time and were respectful of my property. They knew what they were doing and worked quickly and efficiently. They really did good work. The reason I only give four stars is that the communication and customer service with the company is lacking. Scheduling with them was difficult, getting callbacks was difficult, they were not consistent. So if you need something done with your pool the workers are wonderful and knowledgeable but beware of the poor customer service at Imperial Pools Inc.
