The Ranking
Our top 10 pool companies in San Antonio
Pool season in San Antonio is long, and there is no opening and closing routine like the one in northern cities, so most service plans here run all year. The hot months from late spring into fall are when chemistry, algae and worn equipment cause the most service calls. The companies on this list point to the same local problems again and again. Hard, mineral-heavy water leaves a white ring of calcium scale on waterline tile and builds up inside heaters and salt cells. Cedar and oak pollen and leaf drop load skimmers and filters. Heavy rain can throw off a balanced pool and turn it green, as one customer on this list describes, and long stretches of heat wear on pumps, motors and plaster. Hard freezes are rare here, but they do happen, so ask any service company how it protects equipment during a freeze.
Weekly service in San Antonio usually covers skimming, brushing, vacuuming, emptying baskets, testing and balancing the water, and a quick check of the equipment, with filter cleaning every few months. Prices vary with pool size, a spa and how many trees surround the water. Blue Science is the only company on this list that posts its rates: full weekly service from $209 a month and partial service from $149, with a $179 filter cleaning every three to four months. Several of the others are builders whose service departments handle repairs, leak detection and resurfacing, and we say so in each entry.
The City of San Antonio requires an enclosure around private pools, hot tubs and spas deeper than 24 inches. According to the city's Development Services guidance, the barrier must be at least 48 inches high with self-closing, self-latching gates; a privacy fence can serve as the enclosure, and lockable safety covers are accepted as an alternative. Residential pool and spa permits go through the city's BuildSA portal. If a repair involves fencing, gates or new equipment, ask whether a permit is needed.
For licensing, the Texas Department of Licensing and Regulation says holders of a Residential Appliance Installer licence may install and replace pool pumps, motors, heaters, underwater lights and automation on the load side of the control panel, while work that needs a new or upgraded circuit is reserved for a licensed electrical contractor. Before any equipment job, ask for the TDLR licence number and check it on the TDLR licence search. For routine cleaning, ask for proof of liability insurance and get the service plan, including what chemicals are covered, in writing.
