One name runs through nearly every review of this Methuen pool service: Drew. Diamond Pool Service — customers also write it as Diamond Pools — handles the seasonal round of openings, closings and cleanings, plus the equipment work that decides whether a summer is salvageable. The most recent write-ups are about hardware, not housekeeping. This August a customer had a sand filter repaired and a pool pump replaced in the same season, and mentioned that Drew swung back a week later while he was in the neighborhood to make sure the new pump was running right. In May another homeowner, referred by the contractor who built their pool patio, dealt with John and came away describing him as quick to answer and deep on the equipment side. The rescue jobs are what customers write longest about. In a June 2024 review, a homeowner described a pool "as green as can be" when the crew first arrived, and their first calm season after it; in a 2025 review, another credited him with saving a pool after sand got into it and has used him for openings, closings and cleanings ever since. A September 2024 customer called him honest and prompt after a previous company had closed their pool badly. The one thing worth pinning down is the quote. In July 2024 a homeowner asked about replacing the filter pump on an inground pool, got a fast callback, and was told $1,900 for the pump, installation, fittings and labor — a figure they already thought high. Drew said he would confirm the price against their exact pump, and the customer left a one-star review after the conversation stopped there. Nothing since suggests it repeated, but get the scope and the number in writing before work is scheduled. A reasonable call for Merrimack Valley homeowners who want one person handling the season start to finish and the pump-and-filter problems in between. Just note how short the written history is — eight reviews since 2024, all on Google — so treat the strong tone as encouraging rather than settled, and confirm pricing up front.
Drew is great. He repaired my sand filter and replaced my pool pump this summer, and both were positive experiences. He’s responsive, reliable, and easy to schedule with. He even stopped by a week later while he was in the neighborhood to check in and make sure the new pump was working properly. Highly recommend!
I was introduced to Diamond Pools by a contractor who did our pool patio. John from Diamond Pools was very responsive and extremely knowledgeable about our pool and equipment. His service, communication and timeliness is excellent. Highly recommend!!
THESE GUYS ARE AWESOME
Drew is fantastic. He saved our pool after sand got in it, ever since then we have been using him for openings, closings, and some cleanings. Great guy and easy communication. Highly recommend giving diamond pools a shot!
Drew opened our pool after another company had improperly closed it for us prior. He was honest, knowledgeable and prompt from start to finish! Was very happy with our experience using Diamond Pools :)
