"Great working with Angelo and his team. They did a fantastic job of repairing pool leaks, coping, tile, and completing the area around the pool. They cleaned up after themselves, were approachable, hard-working, and courteous. I will hire them again!"

"Juston he is amazing! Poseidon pool service company is a big reason why we started using their service but Juston is the main reason why we stay with this company. They service our pool to a level like Iâ  ve never experienced before. Iâ  ve owned many many pools in my lifetime and Iâ  ve never had such a good quality of pool service at a great price. Cole the owner is fantastic but nobodyâ  s as good as Juston"

Pool and Spa Servicing FAQs, answered by experts

Properly maintaining your hot tub will prevent serious issues from occurring down the road. You should replace the filter once a year, regularly look for and repair small cracks in the shell, and test the water quality every few months. You can do this yourself for less than $100 per year.

You can also hire a hot tub service to service your hot tub annually to identify problems early, which could save you money in the long run. They cost about $100 to $200 per call.

Hot tub maintenance can cost between $500 and $1,000 annually. These costs typically cover deep cleaning the tub, refilling it several times a year, and maintaining the water's chemical balance. While you can perform maintenance yourself, a professional can clean and treat your hot tub with chemicals to save you time. The biggest expenses are often heating and repairs, but regular maintenance can help you avoid more complicated and costly repairs and preserve your investment.

Yes, hot tubs can use a significant amount of electricity, primarily to keep the water heated. A typical hot tub uses between 1,500 and 6,000 watts, and the pump can add another 1,500 watts. This usage can result in a monthly cost of around $20 to $30. The exact amount of electricity consumed depends on several factors, including the hot tub's age, size, heater voltage (120V vs. 240V), usage habits, and thermostat setting. Newer, energy-efficient models generally use less power than older ones. To reduce electricity costs, consider investing in an energy-efficient model, using a quality insulated cover with a thermal blanket, and keeping the filters clean.

In most cases, it is safe to clean a hot tub with vinegar. You will want to verify that your hot tub manufacturer lists vinegar as a safe cleaning product; however, given that vinegar is chemical-free, cleans, deodorizes, and is safe for people and pets, it is usually a good option. You can use vinegar to clean the hot tub shell, interior and exterior spa surfaces, hot tub jets, hot tub filter, and other parts. It is considered a strong, safe, and natural cleanser that can kill bacteria, remove mold and mildew spores, erase water spots, and remove hard water stains.

For a fully-foamed hot tub, freezing typically occurs when the temperature drops below 28 degrees Fahrenheit and remains at or below this level continuously for a minimum of 36 hours. If your hot tub and pumps are still operational, however, the water circulates, and this continuous movement helps prevent freezing, even in very cold conditions. This circulation, along with the insulation provided by the foam, helps maintain the water temperature and prevent it from freezing during extended cold periods. Still, if you’re not planning to run it regularly, be sure to winterize the hot tub properly to prevent damage from freezing.
