Diamond Pools is a Cape Cod and South Shore pool-service company focused on the practical work that keeps a pool usable: openings, cleaning, maintenance, repairs, winterization, liner replacement, and pool-cover services. Its website also describes pool design and safety or automatic-cover work. The three recent Google reviews are all five-star accounts. One homeowner cited punctual arrival, advance reminders, and efficient service; another described years of pool openings and closings, fair competitive rates, and a knowledgeable, hard-working operator. A May 2026 reviewer said communication was clear and planned to use the company again. For an owner looking for seasonal pool care or repair, the clearest next step is to discuss the scope of the opening, closing, maintenance, or cover work needed. The written reviews point most directly to recurring service and communication rather than a large documented portfolio of design projects.
Excellent communication, showed up on time, and sent an email a week prior as a reminder. Very proficient and efficient service, and a nice person! I plan to use again.
John owner of Diamond Pools one of the most knowledgeable and professional pool guys out there if I could give him 6 stars I would. He is responsible and well worth the money. He always goes above and beyond. Mike in Forestdale
John @ Diamond has opened and closed our pool for a few years now. He is friendly, hard working, and knows what he’s doing. His rates are fair and competitive.
