"Compared to numerous hot tub repairs I had experienced/endured with other company all these years, Mr. Sergie's service (from the beginning to the end) is excellent - on time, responsible, professional, knowledgeable and friendly. Mr. Segie's work is neat and efficient. He gets the job done without any confusion or uncertainty. He will be my go to guy for any hot tub issues from now on. Also, I highly recommend him/spa total upgrade, LLC for everyone who needs hot tub services. Overall, GOOD JOB/ EXCELLENT SERVICE!!!"

"I had an amazing experience. From the moment Victor walked in my backyard to fix my pool, I knew my problem would be solved. He’s knowledgeable, professional, friendly and talked me through everything that he was doing. When I say top notch customer service I really mean it. I hired him on the spot to open and close my pool. If you want quality service I recommend BPS. They exceeded our expectations. Thank you so much!!!!!"

"Robin was very nice and informed, easily reachable any time. Since my spa hasn’t been used and left empty for years Robin has tried to get the information about my spa as much as possible and also guided me to fill the spa with water to see whether there is any leak beforehand in order to save time and money. John and Austin came to work on time. They are very kind, professional and knowledgeable about my unusual type of Emerald spa which was sold only in Staten Island and off the market already. The spa turned out to have leaks and motor problems after testing. John explained it to us in detail , pros / cons for repair and gave advice in customer’s shoes as well. Both Robin and John were willing to take time to answer our questions and concerns. We are glad to hire them and their service is highly recommended."

Pool and Spa Servicing FAQs, answered by experts

Shocking your hot tub means adding extra chemicals to the water. Most spa experts recommend doing this once a week for proper hot tub maintenance, but you can do it more if needed. Shocking has multiple benefits, including preventing the water from becoming murky and it’s essential in removing harmful bacteria from the water.

If you want to have a chemical-free spa, or if you are wondering how to keep your hot tub clean naturally, there are several options. Some individuals choose to run their hot tub without treatment at all and simply clean it more often (although you risk bacteria, fungi, and algae growth if you take this route); others use natural products like vinegar or Borax. Ozone, ultraviolet light, and electrolysis systems are also eco-friendly ways to have a clean hot tub without chemicals. Saltwater hot tubs are popular with people who are sensitive to chlorine, bromine, and other traditional hot tub chemicals.

It’s possible to move a hot tub on its side or base as long as it fits snugly in the moving truck, with plenty of padding around it. This moving method requires specialized equipment and careful planning, like moving straps, dollies, and moving blankets.

Follow these general safety tips for spas and hot tubs:

  • Keep your exterior electrical receptacles covered and dry, especially around your hot tub and pool during periods of use.

  • Make sure you have a GFCI (ground fault circuit interrupter) properly installed to ensure no one gets accidentally shocked or injured by electrocution. 

  • Don’t use the hot tub or your pool during a thunderstorm. 

  • Before using the hot tub, have a certified electrician thoroughly inspect your hot tub and its wiring to make sure you’re in full compliance with all applicable local building codes. 

Whether you can repair a hot tub depends on the severity of the problem and the location. With the right tools and knowledge, you can fix problems like small leaks or switching out a dirty filter. However, electrical and plumbing issues require a licensed professional due to the inherent risk, particularly when mixing water with electricity.
