A new liner in April, then a custom safety cover at the close of the season: a recent Google customer says A-1 Pools & Spas handled both on one custom pool. The company names a service area of Oxford, Southbury, Seymour, Shelton, Middlebury, Beacon Falls and nearby towns, and says it has been in business 43 years. Its Better Business Bureau grade is A+, and it holds 4.3 stars from 78 Google ratings. A customer who hired A-1 for a pool project says the pool came out great and the family is enjoying it every day. One reviewer credits Mario and the team with everything from the design of a pool and patio through annual service. A customer who has used A-1 for years says the company has handled openings, closings, repairs and replacements. At the store, a recent customer calls Tyler knowledgeable and helpful. A 2025 customer said an inground pool was installed at their new construction home and that the installation team arrived on schedule. A 2024 customer who bought a new in-ground pool and an Aspen Spa said Mario, the owner, was with them every step of the way. A 2024 reviewer said A-1 had opened and closed their pool for many years in Wilton, and had rebuilt the pool and replaced heaters and pumps. A 2022 customer said Mario was on site daily for a custom in-ground pool with a sun deck, and that it finished ahead of schedule. A 2021 customer said the team was straightforward about supply-chain delays and long material lead times during their pool install. In a 2015 Houzz review, a customer said A-1 installed an in-ground pool, an above-ground spa and a decorative aluminum fence in Oxford, CT. A recent customer says a service call promised for the end of June, 7 weeks after they called, never happened, and that the owner then said the company was not coming at all. A 2024 customer wrote that they had used A-1 for 20 years before switching providers over bad service and the owner's treatment of people. A 2023 customer wrote that the owner insisted on doing the pool and patio his own way, ignoring their choices.
Mario and his team did an excellent job. They installed a new liner in my custom pool back in April and they installed a custom safety cover at the close of the season. Top notch crew excellent work I highly recommend!! Tyler who runs the front, Excellent customer service. I highly recommend Mike in Oxford ct
So very helpful! Always giving me tips on managing the pool water. Definitely returning!
A1 indicated they would come out to handle a service call on my pool “ end of June” which was 7 weeks from when i called. I waited and called a couple times to nail down the day with never an answer. After 7 weeks, the owner said they are not coming at all with no apology or discussion. I asked for owner to call me as that seemed unacceptable. No call. This is now way to run a business.
Hired A1 late last year for our pool project and I could not be any happier with the decision to go with them. Mario and his team went above and beyond with everything they did. Guided me with ideas on what to do and what not to do. Mario is super responsive and professional. Pool came out great and we are enjoying it every day.
Great customer service. Tyler will hook you up
