"Omar, is absolutely amazing. He turned my green pool,crystal blue after just one treatment. I was told from my other pool company that I needed a new pump. That wasn't the case, just needed someone that knows what they are doing. Highly recommend Oasis."

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

Pool and Spa Servicing FAQs, answered by experts

Algae-related green hot tub water is generally safe to use, as algae aren't usually harmful to your health. However, if the conditions in the hot tub are hospitable to algae growth, they may also be hospitable to the growth of other types of microorganisms, including Pseudomonas aeruginosa, bacteria that can cause hot tub rash, or Legionella bacteria, which can cause respiratory illness.

How often you change the water in your swim spa depends on how often you use it. Most manufacturers recommend changing the water every three to six months. If you use your swim spa throughout the seasons, it’s a good idea to set up a quarterly deep cleaning schedule. The ideal instructions should be in the owner’s manual.

To refill a hot tub after winter, start by opening up the tub and giving it a quick cleaning. If you use antifreeze, drain out the water then grab a hose and thoroughly clean the tub shell out, spraying water into each jet of the tub. 

Reconnect the hot tub and turn the power back on. When it’s time to fill the tub again, insert the hose into the filter well (if available). Avoid trapping too much air in the water lines, which can cause the pump to lock up when it starts again. Add the necessary chemicals and start the heating process. It will take some time—most of a full day—for the water to heat up again.

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. 

Hot tub repair costs are less expensive than purchasing a new one, especially if your warranty is still intact. You can shop for a secondhand unit or find a deal for a trade-in. If the price to repair your hot tub is higher than the cost of a new one, consider replacing your unit.
