Editorial Review

Our Take on Blue Science

Blue Science is the most transparent company on this list about price, with posted monthly rates, no contract and a written algae guarantee. It is a multi-state operation, so the local technician matters more than the brand. A good pick for owners who want costs settled up front.

    i had been putting off pool cleaning for over two years, and my backyard pool had turned into a pond with frogs in it. after searching online, i called a pool cleaning service and set up an appointment. brandon arrived right on time, which really mattered to me, and got straight to work. about five hours later, the pool was drained, scrubbed, cleaned, and being refilled with fresh water.<br><br>the final result was a clear, sparkling pool that looked swim-ready again. even with the warm san antonio weather, it feels great knowing the pool is finally back in shape and easy to maintain. very professional, polite, fair pricing, and excellent pool service. he will definitely be my pool guy from now on.

    Blue Science has been our go-to team for pool equipment, service, repairs, and helpful advice in San Antonio.<br><br>Their guidance on protecting our pool system during extreme weather really paid off, and we were able to avoid any equipment damage. In the Texas heat, it also helps to have a company that understands how to keep everything running smoothly and efficiently.<br><br>Over time, they have helped us repair or upgrade our heater, filter, pool cleaner, booster pump, and actuator valves. Their recommendations have always made sense and have helped keep our pool in great shape.<br><br>Brent and the team are friendly, professional, and always courteous. They show up on time, explain the work clearly, and make the whole pool service process easy.<br><br>It is great to have a reliable local pool service company that consistently delivers such strong customer care and quality work.

    Great company! I have worked with Blue Science for many years, and they have always handled my pool cleaning and equipment repair needs quickly for the short-term rental properties I manage. They understand how important fast service is for keeping the pools clean, the water clear, and guests happy. Christopher and the team really care about customer satisfaction, and I truly appreciate their reliable service and attention to detail.

    I switched to a new pool service in San Antonio after not being happy with my previous pool cleaning company, and the difference has been huge. They show up when scheduled, handle the regular pool cleaning, and keep everything running smoothly without me having to follow up.<br><br>Their service updates are clear and helpful, and they stay on top of filter cleaning, water care, and routine maintenance. It really feels like they pay attention to the details and make pool ownership much easier.<br><br>The whole experience has been simple and stress-free. Great people, dependable pool service, and my pool has stayed clean, balanced, and ready to enjoy. Highly recommend.

  • Trevor Wilson5.0

    Highly recommend this pool service team for finishing my pool setup and getting everything ready for regular pool cleaning and maintenance. Maxwell and his crew stepped in after another contractor left the job incomplete, and they made the whole process smooth and stress free. They were professional, on time, easy to reach, and gave me a fair estimate for the remaining work. Maxwell clearly explained my options for the pool finish, equipment, water care, and ongoing cleaning service, which helped me feel comfortable with every final choice. He also went above and beyond with permit details, final setup, and helpful guidance on keeping the pool clean and running well in the San Antonio heat. The team paid close attention to the filtration system, startup, and maintenance needs, and their service was reliable from start to finish. I plan to keep using them for pool cleaning and maintenance going forward and only wish I had found them sooner.

Company Background

About Blue Science

Blue Science does something few pool companies in San Antonio do: it posts its prices. Full weekly service starts at $209 a month and includes routine chemicals, netting, vacuuming, equipment checks and water balancing. The partial plan starts at $149 a month for owners who skim and vacuum themselves. Both plans require a filter cleaning every three to four months at $179, both come without a long-term contract, and both carry a written algae-free and water-balance guarantee. Final quotes depend on pool size, a spa and the amount of landscaping around the water.

The company was founded in 2007 by Gabriel Ullmann, who still owns and runs it, and it says it now serves seven cities. In San Antonio it works from a stand-alone shop at 10855 I-35 on the Northeast side, the address printed on its San Antonio page. The site describes the same technician every week, GPS-verified visits and a photo report before the truck leaves. Beyond weekly care, Blue Science handles equipment repair, leak detection, remodeling and new construction, and its local page mentions the hard water and cedar and oak pollen that San Antonio pools fight.

Credentials on the site include Texas Appliance License TICL 587, licensed, bonded and insured status, and BBB membership since 2010. Reviewers mention Christopher for quick equipment repairs on rental properties, and Brent and Ryan for a resurfacing, tile and waterfall upgrade. Many of the newest reviews are short and use similar wording, so it is worth reading the older ones too. Blue Science holds 4.6 from 330 Google reviews, read November 11, 2026.

Blue Science suits owners who want to know the monthly cost before anyone visits and who dislike contracts. It suits less well owners who want an owner-operator who knows every pool on the route. Before booking, confirm what the filter-cleaning fee covers for your filter type, and check the phone number: Google lists 210-361-5006 while the San Antonio page shows 210-704-1400. You can check the TICL licence on the TDLR licence search.
