"This is our second time hiring WaterMark Swimming Pool Service, and once again, they did not disappoint! This most recent project was more extensive, as we needed our pool completely replastered. Not only was WaterMark’s quote thousands of dollars less than other companies, but their team was also professional, fast, and extremely efficient. Nick and his crew did an amazing job from start to finish. They had our pool completely finished and back up and running in just a week and a half! We couldn’t be happier with the quality of their work and the overall experience. If you’re looking for a reliable, professional, and affordable pool company, we highly recommend WaterMark Swimming Pool Service! ⭐⭐⭐⭐⭐"

"I honestly dont even know where to start we love Do Rite construction I would hire this company 100 times over and over again. Louie and his brother are such amazing people. We decided to get a pool all because of this covid 19.Not knowing to much about in ground pools Louie answered all the questions we had from start to finish. They started our pool ahead of schedule and kept us informed the whole time . His company was the most reasonable price that we had. In the end he explained everything to us till we were confident with how to work our pool and said if we had any questions to feel free to call him anytime he truly cares. Our pool looks amazing our 2 kids love it and cant wait to have pool party's. TRUST ME FOLKS YOU WONT BE SORRY ! LOUIE AND HIS CREW ARE AMAZING :)"

"This is the second time that Dig M Pools did and installation for us. Again we were very happy with the job they did. We purchased our pool from them and it is a well made product. The owners wife was very helpful when we were deciding what pool to purchase. I would recommend Dig M Pools as first choice. Excellent job. Thanks Dig M."

"Great work and service by Eric, Ricardo and the crew. They went above and beyond with fixing the fireplace stone, power washing the patio, installing our grill, running the gas line from the house to the grill, and reporting the patio and stone wall. Highly recommend their service."

"could not be happier. They did a great job for a lot less than other contractors that gave me bids. Glen the owner made sure everything was done right. Since you don't do this very often I was concerned about getting someone to do this but Leisure pools was all I could have asked for."

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.

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.

Yes. If you test the water and the alkalinity is too low, you can raise it by adding an alkalinity increaser, which likely came with your hot tub’s chemical kit. In a pinch, you can use baking soda to raise the hot tub’s alkalinity. Raising the alkalinity will prevent the hot tub water from becoming too acidic.

Many people find saltwater tubs worth the upfront expense. They cost less to maintain than traditional hot tubs, so you can save in the long term. Maintenance is also easier, typically involving balancing the pH and cleaning the tub rather than adding chemicals. They’re also gentler on sensitive skin, and you won’t walk away with a strong chlorine odor.

You should have your spa or hot tub inspected and serviced yearly to prevent more costly repairs. Regular hot tub maintenance can save money and help keep you safe from hazards such as faulty wiring. Call a professional hot tub repair specialist, who will know what common issues to look for and have the parts and tools on hand to fix them immediately.
