"Cannot recommend more highly! My pool heater went out the morning we were hosting my 9-year old daughter’s birthday pool party. Naji arrived within an hour of contacting him, found that the issue was only a loose wire, and charged me only a home visit fee - on a Saturday! Everyone else that I reached over the phone wanted to schedule weeks out and recommended replacing the equipment. I’m so pleased, I will look for more work to send his way!!"

"I have been impressed with Oasis Pool Service, LLC, led by Kevin and his dedicated team. Their expertise in pool maintenance, particularly in chemical management, has made a significant difference in the clarity and health of my pool. Kevin has an extensive understanding of water chemistry and ensures that pH levels, chlorine, and alkalinity are meticulously monitored and adjusted. This careful attention has not only kept the water safe for swimming but has also contributed to the longevity of my pool equipment. I appreciate Kevin's commitment to educating me about the importance of regular chemical maintenance. He proactively identifies potential issues, saving me both time and future costs. Overall, I recommend Oasis Pool Service, LLC for anyone seeking reliable pool care, especially regarding chemical management. Their professionalism and dedication to quality service are commendable."

"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."

"Matt and his team did a FANTASTIC job of getting exactly the work we needed. Matt is so kind and really listened to our needs and our budget and was able to tailor the project to give us exactly what we were hoping for. Additionally we were able to get the work done really quickly and the team were very professional, worked quickly, were on time, and left the job site spotless. I am so relieved and grateful we found Matt at Paradise Pools- we weren’t expected to need to have a fiberglass pool repair/resurface when we moved to a new house, and people with the skills to do the job are few and far between. Definitely give them a call if you need work done on your pool!"

Pool and Spa Servicing FAQs, answered by experts

Yes, you can use silicone or epoxy hot tub repair kits to repair cracks in a hot tub. Always read the manual to see what the manufacturer recommends before attempting to repair a hot tub.

No. In fact, some owners prefer to “summerize” their hot tubs and use them primarily over winter to enjoy the contrast of cold and hot water. It’s possible to keep the tub filled and running year-round, and some pros may even recommend this method compared to the work and risks of a full winterization every year.

However, keeping the hot tub running will require additional resources. You’ll use more power and more chemicals to keep it in good shape. Weigh the pros and cons of your situation before making a decision.

Hot tubs don’t necessarily add value to a home—but they don’t take it away either. It depends on the potential buyer. A well-landscaped in-ground hot tub is attractive to buyers who prioritize relaxation and fun. Others would rather not deal with the maintenance. 

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.

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.
