"Very happy with service. They came out inspected my pool leak and repaired a crack. That didn't do the trick unfortunately so they returned the next day and found a leaking pipe. That was fixed and we're all-set. Very happy with quick response, great communication and reasonable pricing."

"Very thorough and helpful in going over the equipment and maintenance. As well as the seasonal requirements that a pool needs. I thought the water just needed to stay chlorinated but there is so much more. Great company I would recommend to anyone."

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.

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 repairs cost between $200 and $500 on average. You can minimize those costs by maintaining your hot tub and keeping necessary supplies on hand. An elevated shelf in the garage is a great place to store your water care chemicals so that kids and pets will stay safe and you’ll always have them around. 

Your hot tub should be drained of existing water, cleaned, and refilled every three to four months at a minimum. Follow your tub manufacturer’s recommendations for cleaning, and rinse thoroughly when finished to eliminate any residue from the cleaning products. This is also a good time to inspect your tub’s cover in good lighting for any leaks, tears, or other damage that might cause problems. 

Using your hot tub manufacturer’s suggested cleaners and methods, keep your hot tub filters clean to avoid a loss of water heat. This will help extend the filter’s useful life and efficiency. If the filter is more than two to three years old, replace it with a new one and buy a second filter to keep around as a spare.

You can and should use a hose to fill a hot tub. There shouldn’t be anything special about the hose other than it shouldn’t be damaged. Kinks or leaks could slow down the filling process. Attach the hose to the nearest spigot and get the water flowing.

If you don’t clean your hot tub filters, they’ll build up dirt and grime, preventing them from filtering out contaminants like dirt and bacteria. The dirty water will then circulate through the filter and back into the hot tub, leading to dirty water, a damaged pump and jets, and low heat. This can lead to higher hot tub costs because you may have to pay for repairs.
